RESUMO
PURPOSE: The objective of this study is to perform a meta-analysis comparing the effectiveness of uterine artery embolization (UAE) versus peripartum hysterectomy for acute refractory postpartum hemorrhage (PPH) control. MATERIALS AND METHODS: We systematically searched 6 medical databases for studies comparing UAE and hysterectomy in PPH. Outcomes examined were mortality, hospitalization duration (HD) in days, and red blood cells (RBC) units utilization. Statistical analysis used RevMan 5.1.7 and random-effects models. Odds ratios (OR) and mean differences (MDs) with 95% confidence intervals (CIs) were used for dichotomous and continuous outcomes, respectively. RESULTS: We included 833 patients from 4 cohort studies, with 583 (70%) undergoing UAE. The UAE population required fewer RBC units (MD: -7.39; 95% CI: -14.73 to -0.04; p=0.05) and had shorter HD (MD: -3.22; 95% CI: -5.42 to -1.02; p=0.004). Lower mortality rates were noted for UAE in the pooled analysis, but no statistical significance. Uterine artery embolization demonstrated lower procedural complications (16.45% vs. 28.8%), in which UAE had less ureter and bladder lesions (OR: 0.05; 95% CI: 0.01-0.38; p=0.004 and OR: 0.02; 95% CI: 0.00-0.15; p<0.001, respectively). Only 35 (6%) required conversion to hysterectomy, while 27 (4.6%) underwent re-embolization with 100% bleeding control. Uterine artery embolization did not hinder fertility, with normal menstruation restored in 19 patients with postoligomenorrhea. CONCLUSION: Uterine artery embolization for the control of PPH is associated with lower use of RBC units and HD, but similar rates of mortality are noted when compared to hysterectomy. These results associated with uterine preservation could support its importance for refractory PPH management. CLINICAL IMPACT: Uterine Artery Embolization is associated with a shorter hospitalization duration and reduced use of red blood cell units when compared with hysterectomy in refractory postpartum hemorrhage. Although demonstrating similar mortality rates, these findings, together with fertility preservation, support the method incorporation as a valuable option in obstetric services.
RESUMO
INTRODUCTION: Cesarean scar ectopic pregnancies (CSEPs) are associated with significant maternal morbidity and termination is often recommended in the early first trimester. Management of more advanced cases is challenging due to higher risks of major intraoperative hemorrhage. Hysterectomy is currently the intervention of choice for advanced cases. This study aimed to investigate if advanced live CSEPs could be managed effectively conservatively using suction curettage and interventional radiology. MATERIAL AND METHODS: A retrospective single-center cohort study was performed. A total of 371 women diagnosed with CSEP were identified between January 2008 and January 2023. A total of 6% (22/371) women had an advanced live CSEP with crown-rump length (CRL) of ≥40 mm (≥10 weeks' gestation). Of these, 77% (17/22) opted for surgical intervention, whilst the remaining five continued their pregnancies. A preoperative ultrasound was performed in each patient. All women underwent suction curettage under ultrasound guidance and insertion of Shirodkar cervical suture as a primary hemostatic measure combined with uterine artery embolization (UAE) if required. The primary outcome was rate of blood transfusion. Secondary outcomes were estimated intraoperative blood loss, UAE, intensive care unit admission, reintervention, hysterectomy, hospitalization duration and rate of retained products of conception. Descriptive statistics were used to describe these variables. RESULTS: Median CRL of the 17 patients included was 54.1 mm (range: 40.0-85.7) and median gestational age based on CRL was 12 + 3 weeks (range: 10 + 6-15 + 0). On preoperative ultrasound scan placental lacunae were recorded in 76% (13/17) of patients and color Doppler score was ≥3 in 67% (10/15) of patients. At surgery, Shirodkar cervical suture was used in all cases. It was successful in achieving hemostasis by tamponade in 76% (13/17) of patients. In the remaining 24% (4/17) patients tamponade failed to achieve complete hemostasis and UAE was performed to stop persistent arterial bleeding into the uterine cavity. Median intraoperative blood loss was 800 mL (range: 250-2500) and 41% (7/17) women lost >1000 mL. 35% (6/17) needed blood transfusion. No women required hysterectomy. CONCLUSIONS: Surgical evacuation with Shirodkar cervical suture and selective UAE is an effective treatment for advanced live CSEPs.

BACKGROUND: There have been conflicting outcomes regarding the use of lidocaine to reduce pain after uterine artery embolization (UAE). PURPOSE: To investigate the efficacy of intra-arterial lidocaine injection for pain and inflammatory response control within 24â h of UAE for symptomatic uterine fibroids. MATERIAL AND METHODS: Of 1530 patients who underwent UAE for uterine fibroids in 2007-2021, 5â mL of 1% lidocaine was injected into each uterine artery immediately after UAE in 23 patients. A disease-matched control group (n = 23) who did not receive intra-arterial lidocaine was generated from the same registry. The pain score, white blood cell (WBC) count, C-reactive protein (CRP), neutrophil/lymphocyte ratio (NLR), and fentanyl consumption were compared before and after UAE. Complete infarction of the dominant fibroid was assessed using magnetic resonance imaging. RESULTS: Significantly lower WBC count, CRP level, and NLR were noted 24â h after UAE in the lidocaine group. No statistically significant difference was noted in the pain score between groups at 0-24â h. The cumulative fentanyl dose administered during the first 24â h after UAE was not significantly different. After embolization, fibroid-related symptoms resolved in all patients. No significant difference was observed in the rate of complete infarction of the dominant fibroid. CONCLUSION: Lidocaine administration immediately after UAE resulted in a significant reduction in the inflammatory response. However, such a difference in the inflammatory reaction did not contribute to significant reductions in pain scores or fentanyl consumption.

BACKGROUND: Postpartum hemorrhage (PPH) and post-abortion hemorrhage (PAH) are life-threatening conditions. PURPOSE: To evaluate the efficacy and safety of uterine arterial embolization (UAE) for PPH and PAH and to investigate future fertility after UAE. MATERIAL AND METHODS: This study included 57 consecutive patients (mean age = 34 years) who underwent UAE for PPH (n = 46) and PAH (n = 11) at our institution between January 2011 and December 2022. Technical success, non-visualization of the peripheral portion of bilateral uterine arteries on angiography, and clinical success, complete hemostasis after UAE, were assessed. UAE-associated complications and factors related to clinical success were analyzed. Pregnancy outcomes after UAE and complications during subsequent pregnancy were investigated in 16 patients who desired fertility and were followed up for >1 year. RESULTS: The technical and clinical success rates were 100% and 84.2%, respectively. Sepsis (n = 1) and uterine empyema (n = 1) were observed as severe complications. Placental disorder, bleeding within 24â h after delivery or abortion, ≥1.5 shock index, ≥6 units of transfusion erythrocytes, and ≥8 obstetrical disseminated intravascular coagulation score were significantly associated with unfavorable clinical outcomes. In total, 16 pregnancies were observed in 12 patients after UAE, three of which were miscarriages and 13 were successful live births. During pregnancy, uterine rupture (n = 1) and accreta (n = 1) were observed. CONCLUSION: UAE is an effective treatment for PPH and PAH. Although UAE could preserve future fertility, careful attention should be paid to perinatal management for unusual complications.

PURPOSE: Postpartum haemorrhage (PPH) remains a leading cause of maternal death despite current medical management. Surgical interventions are still needed for refractory bleeding. Interventional radiology (IR) can be a successful intermediary that avoids the need for hysterectomy. Nevertheless, IR outcome data in a peripartum setting are limited. The objective of this study is to document the efficacy and safety of IR. METHODS: Retrospective study reviewed the records of consecutive patients who underwent peripartum IR from 01/01/2010 until 31/12/2020 in a tertiary academic centre. Patients were divided in a prophylactic and a therapeutic group. Information about interventions before and after IR, and IR specific complications was retrieved. Efficacy was defined by the number of transfusions and additional surgical interventions needed after IR, and safety was assessed by the incidence of IR related complications. RESULTS: Fifty-four patients, prophylactic group (n = 24) and therapeutic group (n = 30), were identified. In both groups, IR was successful with 1.5 ± 2.9 packed cells transfused post-IR (1.0 ± 2.1 prophylactic vs 1.9 ± 3.3 therapeutic; p = 0.261). Additional surgical interventions were required in n = 5 patients (9.2%), n = 1 (4.2%) in the prophylactic vs. n = 4 (13.3%) in the therapeutic group. Complications were reported in n = 12 patients (22.2%), n = 2 (8.3%) prophylactic vs. n = 10 (33.3%) in therapeutic group. Mostly minor complications, as puncture site hematoma or bleeding, were reported in n = 4 (7.4%). Severe complications as necrosis and metabolic complications were reported in n = 2 patients (3.9%). CONCLUSION: IR for prevention and treatment of PPH was highly successful and associated with minor complications.
RESUMO
Background and Objectives: Cesarean scar pregnancy (CSP) represents a type of ectopic pregnancy in which the embryo implants inside the scar of a previous cesarean section. This condition can lead to maternal morbidity and mortality. The best therapeutic approach in terms of clinical effectiveness and patient safety for CSP has not been described yet, although different therapeutic strategies are currently available. The purpose of the present study was to analyze the success rate of two different treatments in a single institution. Materials and Methods: A retrospective study was performed among patients diagnosed with CSP at the Gynecology and Obstetrics Department of the "Cannizzaro" Hospital in Catania (University of Enna-Italy) from January 2016 to December 2022. The diagnosis was made by 2D/3D transvaginal ultrasound, following Timor-Tritsch criteria. Two treatment strategies were performed: local and systemic methotrexate (MTX) injection and uterine artery embolization (UAE) with subsequent dilatation and curettage (D&C). All treated women underwent subsequent clinical and sonographic follow-up. Complete recovery was defined as the reduction of ß-HCG values until it was undetectable and the disappearance of the mass in the uterine scar on ultrasound. Results: Nineteen patients were included; nine were in the MTX group and ten were in the UAE + D&C group. No significant differences were found between the two groups in terms of clinical parameters. Treatment was successful in 4 of 10 (44%) patients in the MTX group and 10 of 10 (100%) in the UAE + D&C group (p = 0.01); the length of hospital stay was significantly shorter in the latter group (p < 0.0001). Conclusions: In our experience, administration of MTX is not recommended as the primary treatment or pre-treatment. Dilatation and curettage after uterine artery embolization are better than methotrexate injection for the treatment of cesarean scar pregnancy in a single-institution series in terms of complete recovery and length of hospital stay.

BACKGROUND: Placenta accreta spectrum disorders are a continuum of placental pathologies with significant maternal morbidity and mortality. Morbidity is related to the overall degree of placental adherence, and thus patients with placenta increta or percreta represent a high-risk category of patients. Hemorrhage and transfusion of blood products represent 90% of placenta accreta spectrum morbidity. Both tranexamic acid and uterine artery embolization independently decrease obstetrical hemorrhage. OBJECTIVE: This study aimed to provide an evidence-based intraoperative protocol for placenta accreta spectrum management. STUDY DESIGN: This study was a pre- and postimplementation analysis of concomitant uterine artery embolization and tranexamic acid in cases of patients with antenatally suspected placenta increta and percreta over a 5-year period (2018-2022). For comparison, a 5-year (2013-2017) preimplementation group was used to assess the impact of the uterine artery embolization and tranexamic acid protocol for placenta accreta spectrum. Patient demographics and clinically relevant outcomes were obtained from electronic medical records. RESULTS: A total of 126 cases were managed by the placenta accreta spectrum team, of which 66 had suspected placenta increta/percreta over the 10-year time period. Two patients were excluded from the postimplementation cohort because they did not undergo both interventions. Thus, 30 (30/64; 47%) were treated after implementation of the uterine artery embolization and tranexamic acid protocol for placenta accreta spectrum, and 34 (34/64; 53%) preimplementation patients did not undergo uterine artery embolization or tranexamic acid infusion. With the uterine artery embolization and tranexamic acid protocol, operative times were longer (416 vs 187 minutes; P<.01), and patients were more likely to receive general anesthesia (80% vs 47%; P<.01). However, blood loss was reduced by 33% (2000 vs 3000 cc; P=.03), overall blood transfusion rates decreased by 51% (odds ratio, 0.05 [95% confidence interval, 0.001-0.20]; P<.01), and massive blood transfusion (>10 units transfused) was reduced 5-fold (odds ratio, 0.17 [95% confidence interval, 0.02-0.17]; P=.02). Postoperative complication rates remained unchanged (4 vs 10 events; P=.14). Neonatal outcomes were equivalent. CONCLUSION: The uterine artery embolization and tranexamic acid protocol for placenta accreta spectrum is an effective approach to the standardization of complex placenta accreta spectrum cases that results in optimal perioperative outcomes and reduced maternal morbidity.

BACKGROUND: Few studies have directly compared different surgical procedures for uterine fibroids with respect to long-term health-related quality of life outcomes and symptom improvement. OBJECTIVE: We examined differences in change from baseline to 1-, 2-, and 3-year follow-up in health-related quality of life and symptom severity among patients who underwent abdominal myomectomy, laparoscopic or robotic myomectomy, abdominal hysterectomy, laparoscopic or robotic hysterectomy, or uterine artery embolization. STUDY DESIGN: The COMPARE-UF registry is a multiinstitutional prospective observational cohort study of women undergoing treatment for uterine fibroids. A subset of 1384 women aged 31 to 45 years who underwent either abdominal myomectomy (n=237), laparoscopic myomectomy (n=272), abdominal hysterectomy (n=177), laparoscopic hysterectomy (n=522), or uterine artery embolization (n=176) were included in this analysis. We obtained demographics, fibroid history, and symptoms by questionnaires at enrollment and at 1, 2, and 3 years posttreatment. We used the UFS-QoL (Uterine Fibroid Symptom and Quality of Life) questionnaire to ascertain symptom severity and health-related quality of life scores among participants. To account for potential baseline differences across treatment groups, a propensity score model was used to derive overlap weights and compare total health-related quality of life and symptom severity scores after enrollment with a repeated measures model. For this health-related quality of life tool, a specific minimal clinically important difference has not been determined, but on the basis of previous research, a difference of 10 points was considered as a reasonable estimate. Use of this difference was agreed upon by the Steering Committee at the time when the analysis was planned. RESULTS: At baseline, women undergoing hysterectomy and uterine artery embolization reported the lowest health-related quality of life scores and highest symptom severity scores compared with those undergoing abdominal myomectomy or laparoscopic myomectomy (P<.001). Those undergoing hysterectomy and uterine artery embolization reported the longest duration of fibroid symptoms with a mean of 6.3 years (standard deviation, 6.7; P<.001). The most common fibroid symptoms were menorrhagia (75.3%), bulk symptoms (74.2%), and bloating (73.2%). More than half (54.9%) of participants reported anemia, and 9.4% women reported a history of blood transfusion. Across all modalities, total health-related quality of life and symptom severity score markedly improved from baseline to 1-year with the largest improvement in the laparoscopic hysterectomy group (Uterine Fibroids Symptom and Quality of Life: delta= [+] 49.2; symptom severity: delta= [-] 51.3). Those undergoing abdominal myomectomy, laparoscopic myomectomy, and uterine artery embolization also demonstrated significant improvement in health-related quality of life (delta= [+]43.9, [+]32.9, [+]40.7, respectively) and symptom severity (delta= [-]41.4, [-] 31.5, [-] 38.5, respectively) at 1 year, and the improvement persisted from baseline for uterine-sparing procedures during second (Uterine Fibroids Symptom and Quality of Life: delta= [+]40.7, [+]37.4, [+]39.3 SS: delta= [-] 38.5, [-] 32.0, [-] 37.7 and third year (Uterine Fibroids Symptom and Quality of Life: delta= [+] 40.9, [+]39.9, [+]41.1 and SS: delta= [-] 33.9, [-]36.5, [-] 33.0, respectively), posttreatment intervals, however with a trend toward decline in degree of improvement from years 1 and 2. Differences from baseline were greatest for hysterectomy; however, this may reflect the relative importance of bleeding in the Uterine Fibroids Symptom and Quality of Life, rather than clinically meaningful symptom recurrence among women undergoing uterus-sparing treatments. CONCLUSION: All treatment modalities were associated with significant improvements in health-related quality of life and symptom severity reduction 1-year posttreatment. However, abdominal myomectomy, laparoscopic myomectomy and uterine artery embolization indicated a gradual decline in symptom improvement and health-related quality of life by third year after the procedure.

BACKGROUND: Although abnormal uterine bleeding is a known adverse effect of anticoagulant drugs, true rates have not been widely studied. Society-backed recommendations and guidelines do not yet exist for prevention and management of abnormal uterine bleeding among anticoagulated patients. OBJECTIVE: This study aimed to describe the incidence of new-onset abnormal uterine bleeding among patients receiving therapeutic anticoagulation by anticoagulant class, and to evaluate gynecologic treatment patterns. STUDY DESIGN: We conducted an institutional review board-waived retrospective chart review of female patients aged 18 to 55 years and prescribed therapeutic anticoagulants, including vitamin-K antagonists, low-molecular-weight heparins, and direct oral anticoagulants, in an urban hospital network from January 2015 through January 2020. We excluded patients with antecedent abnormal uterine bleeding and menopause. Associations between abnormal uterine bleeding, anticoagulant class, and other covariates were evaluated with Pearson chi-square and analysis-of-variance tests. The primary outcome, abnormal uterine bleeding odds by anticoagulant class, was modeled with logistic regression. Age, antiplatelet therapy, body mass index, and race were included in our multivariable model. Secondary outcomes included emergency department visits and treatment patterns. RESULTS: Of the 2479 patients who met the inclusion criteria, 645 were diagnosed with abnormal uterine bleeding after initiating therapeutic anticoagulation. After adjusting for age, race, body mass index, and concurrent use of antiplatelet therapy, those receiving all 3 classes of anticoagulants had higher odds of experiencing abnormal uterine bleeding (adjusted odds ratio, 2.63; confidence interval, 1.70-4.08; P<.001), whereas those taking only direct oral anticoagulants had the lowest odds (adjusted odds ratio, 0.70; confidence interval, 0.51-0.97; P=.032), with vitamin-K antagonists as the reference group. Race other than White was associated with higher odds of abnormal uterine bleeding, as was lower age. The most common hormone therapies used among patients with abnormal uterine bleeding were levonorgestrel intrauterine devices (7.6%; 49/645) and oral progestins (7.6%; 49/645). Sixty-eight patients (10.5%; 68/645) had an emergency department visit for abnormal uterine bleeding; 29.5% (190/645) of patients received a blood transfusion; 12.2% (79/645) began any pharmacologic therapy for bleeding; and 18.8% (121/645) underwent any gynecologic procedure. CONCLUSION: Abnormal uterine bleeding occurs frequently among patients on therapeutic anticoagulation. Incidence in this sample varied considerably by anticoagulant class and race; use of single-agent direct oral anticoagulation carried the lowest risk. Important sequelae such as bleeding-related emergency department visits, blood transfusions, and gynecologic procedures were common. Balancing bleeding and clotting risk in patients on therapeutic anticoagulation requires a nuanced approach and should involve collaborative management between hematologists and gynecologists.

OBJECTIVE: To evaluate angiographic findings and outcomes of repeat uterine artery embolization (UAE) for recurrent postpartum hemorrhage (PPH) in patients who previously underwent UAE for PPH after a previous delivery. MATERIALS AND METHODS: Among 1805 patients who underwent UAE for PPH from 2007 to 2020 at four participating hospitals, the data of 21 (1.16%) patients who underwent UAE for PPH after subsequent delivery were collected and analyzed retrospectively. The rate of placental abnormalities, causes of PPH, angiographic findings, and clinical success rate were evaluated. RESULTS: The technical success rates were 100% and 95.2%, and clinical success rates were 85.7% and 95.2% in association with first and second UAEs, respectively. The time intervals between first and second UAEs ranged from 15.6 to 103.3 months (46.5 ± 25.0 months). The rate of placental abnormalities was significantly higher in association with second UAEs than with first UAEs (71.4% vs. 42.8%, p = 0.034). The causes of PPH were different between first and second UAEs with borderline significance (p = 0.049); uterine atony (81.0%) and placenta accreta spectrum (57.1%) were most common in association with first and second UAEs, respectively. During second UAEs, obliterated arteries were observed in 27 uterine arteries (27/42, 64.3%) of 16 patients (16/21, 76.2%), with partial obliteration predominating over total obliteration. Collateral arteries were observed in 15 patients during second UAEs. CONCLUSION: Repeat UAE is safe and effective for recurrent PPH after subsequent delivery in patients with prior UAE. Obliteration of UAs and formation of collateral arteries are common at the second UAEs. KEY POINTS: ⢠The rate of placental abnormalities was significantly higher in association with second UAEs than with first UAEs (71.4% vs. 42.8%, p = 0.034). ⢠Obliteration of UAs and formation of collateral arteries are common at the second UAEs. ⢠Repeat UAE is safe and effective for recurrent PPH after subsequent delivery in patients with prior UAE.

OBJECTIVES: To investigate whether the number and size of endometrial-leiomyoma fistulas (ELFs) change following uterine artery embolization (UAE) for leiomyoma and the correlation between ELFs and vaginal discharge (VD). MATERIALS & METHODS: This study was a retrospective analysis of 100 patients who underwent UAE at a single institution between May 2016 and March 2021. They all underwent MRI at baseline, 4 months, and 1 year after UAE. The number and size of the ELFs were compared with the MRI images each time. The ELF tumor characteristics and the correlation between the ELFs and VD were assessed. Additional gynecologic interventions due to VD associated with ELFs were evaluated. RESULTS: No ELF was observed at baseline. Ten ELFs were noted in nine patients at 4 months, and 35 ELFs were noted in 32 patients 1 year after UAE. The ELFs significantly increased over time (p = 0.004, baseline vs. 4 months; p < 0.001, 4 months vs. 1 year). The ELF size did not significantly change over time (p = 0.941). The tumors developing ELFs after UAE were mainly located at the submucosal or intramural area contacting the endometrium at baseline, with a mean size of 7.1 (2.6) cm. Nineteen patients (19%) had VD 1 year after UAE. There was no significant correlation between VD and the number of ELFs (p = 0.80). No patients underwent additional gynecologic interventions due to VD associated with ELFs. CONCLUSION: ELFs increased in number and did not disappear over time after UAE in most tumors. CLINICAL RELEVANCE STATEMENT: Despite the MR imaging findings, within the limited data of this study, ELFs were not seemingly associated with clinical symptoms, including VD. KEY POINTS: ⢠Endometrial-leiomyoma fistula (ELF) is a complication of uterine artery embolization (UAE). ⢠ELFs increased in number over time after UAE and did not disappear in most tumors. ⢠Most tumors developing ELFs after UAE were located near/contacted the endometrium and were larger.

OBJECTIVE: To compare the efficacy and safety of different treatment options for cervical pregnancy (CP). MATERIALS AND METHODS: A total of 74 patients diagnosed with CP at Hunan Provincial Maternal and Child Health Care Hospital between January 2016 and September 2022 were retrospectively analyzed. Among them, 31 were treated with uterine artery embolization (UAE) followed by hysteroscopic curettage, 34 were treated with hysteroscopic curettage alone, and nine were treated with high-intensity focused ultrasound (HIFU) followed by hysteroscopic curettage. Medical records and pregnancy outcomes were analyzed. RESULTS: There were no significant differences in age, gravidity, parity, abortion, or preoperative hemoglobin levels among the patients in the three groups; however, significant differences in gestational age, gestational sac diameter, preoperative ß-hCG, and presence of cardiac pulsation were observed (p < 0.05). After treatment, there was no conversion to laparotomy, and the uterus was preserved in all patients. Significant differences in blood loss during curettage, hospitalization costs, hospital days, menstrual recovery interval, ß-hCG decline rates, retained products of conception, and intrauterine adhesions rate among the three groups were observed (p < 0.05). There were no significant differences in the placement of the uterine Foley balloon, effective curettage rate, pre-and postoperative hemoglobin decline, live birth rate, or proportion of subsequent pregnancies among the three groups. CONCLUSION: Our results showed that hysteroscopic curettage, HIFU, and UAE followed by hysteroscopic curettage are safe and effective for treating patients with CP. Compared with the UAE, HIFU has the advantages of lower hospitalization costs, shorter hospital stays, and shorter menstrual recovery intervals.

OBJECTIVES: To investigate the menstruation recovery after two therapeutic regimens, high-intensity focused ultrasound (HIFU) or uterine artery embolization (UAE) combined with ultrasound-guided suction curettage, for premenopausal women with cesarean scar pregnancy (CSP). MATERIALS AND METHODS: Seventy patients with CSP treated with HIFU followed by ultrasound-guided suction curettage and 63 patients with CSP treated with UAE followed by ultrasound-guided suction curettage in our hospital were retrospectively reviewed. The treatment parameters and the menstrual blood loss (MBL) volume at 6 months after the two therapeutic regimens were compared between the two groups. RESULTS: There was no significant difference in treatment results between the two groups. With regard to postoperative MBL volume, 5 out of 70 patients in the HIFU group and 22 out of 63 patients in UAE group exhibited a reduction in MBL, respectively. Multivariate logistic regression revealed that hypomenorrhea was more likely to occur in the UAE group than in the HIFU group (UAE group vs. HIFU group; OR 11.328, 95% CI 3.158-55.871; p < 0.001). CONCLUSION: Compared to UAE, HIFU has less influence on postoperative MBL volume, which may be a fertility-sparing option for patients with CSP.

BACKGROUND: Uterine arteriovenous malformation (UAVM) is a relatively rare but potentially life-threatening situations abnormal vascular connections between the uterine arterial and venous systems. Lack of recognized guidelines and clinic experience, there is a lot of clinic problems about diagnosis and treatment. By analyzing the clinical data of patients with pregnancy-related UAVM, we aim to confirm the safety of direct surgeries and the benefit of pretreatment (uterine artery embolization or medical therapy) before surgery, and to explore more optimal therapies for patients with pregnancy-related UAVM. METHODS: A total of 106 patients in Qilu Hospital of Shandong University from January 2011 to December 2021 diagnosed of pregnancy-related UAVM were involved in this study. Depending on whether preoperative intervention was performed, the patients were divided into direct surgery group and pretreatment group (uterine artery embolization or medical management). Clinical characteristics, operative related factors and prognosis were analyzed. RESULTS: The most common symptom of pregnancy-related UAVM was vaginal bleeding (82.5%), which could also be accompanied by abdominal pain. Pretreatments (uterine artery embolization or medical therapy) had no obvious benefit to the subsequent surgeries, but increased the hospital stay and hospital cost. Direct surgery group had satisfactory success rate and prognosis compared to pretreatment group. CONCLUSION: For pregnancy-related UAVM, direct surgery has good effects and high safety with shorter hospital stays and less hospital cost. What is more, without uterine artery embolization and other medical therapy, patients could remain better fertility in future.

BACKGROUND: Cesarean scar pregnancy (CSP) treated with either high-intensity focused ultrasound ablation (HIFU-a) or uterine artery embolization (UAE) combined with ultrasound-guided dilation and curettage (USg-D&C) was effective. However, there is insufficient comparative research evidence on clinical efficacy and subsequent pregnancy outcomes after previous CSP treatment. This study aims to investigate the efficacy, safety, and subsequent pregnancy outcomes of HIFU-a compared to UAE before USg-D&C for the treatment of CSP. METHODS: Between January 2016 and July 2020, a total of 272 patients received the pretreatment with HIFU-a or UAE(HIFU-a group: n = 118; UAE group: n = 154). The clinical characteristics, treatment success rate, postoperative pregnancy rate and outcome of the two groups were compared and analyzed. RESULTS: The demographic characteristics of the two groups were similar. After pretreatment, the adverse events rate of HIFU-a group was lower than that of UAE group (10.40% (16/154) vs. 40.70% (48/118), P = 0.00). All patients received the USg-D&C. The HIFU-a group was of less intraoperative blood loss (10.00 (5.00-20.00) vs. 12.50 (5.00-30.00) ml, P = 0.03). There was no statistically significant difference between the two groups in success rates. However, the HIFU-a group was of a shorter duration of postoperative vaginal bleeding (12.00 (9.00-13.00) vs. 14.00 (12.00-15.00) days, P = 0.00). There was no significant difference between the two groups in terms of subsequent pregnancy rates (P = 0.317). However, the recurrent CSP (rCSP) rate in the HIFU-a group was lower than that in the UAE group (7.70% (6/78) vs. 19.70%(13/66), P = 0.03). CONCLUSIONS: CSP treated with either HIFU-a or UAE combined with USg-D&C was safe and effective. Although no significant difference was found in the subsequent pregnancy outcomes of the two groups, the rCSP was more common in the UAE group. So, we recommend HIFU-a combined with USg-D&C treatment modality.

BACKGROUND: Caesarean scar pregnancy (CSP) is a special type of ectopic pregnancy with a high risk of massive haemorrhage. Few studies have focused on the efficacy of prophylactic abdominal aortic balloon occlusion as a minimally invasive method in caesarean section. This study aimed to evaluate the effectiveness and safety of prophylactic abdominal aortic balloon occlusion for patients with type III CSP. METHODS: This was a prospective cohort study. Patients with type III CSP in the First Affiliated Hospital of Zhengzhou University from January 2020 to June 2022 were enrolled. Eligible patients received prophylactic abdominal aortic balloon occlusion (defined as the AABO group) or uterine artery embolization (defined as the UAE group) before laparoscopic surgery. Clinical outcomes included intraoperative blood loss, body surface radiation dose, hospitalization expenses, and time to serum ß-hCG normalization, and safety were also assessed. RESULTS: A total of 68 patients met the criteria for the study, of whom 34 patients were in the AABO group and 34 patients were in the UAE group. The median intraoperative blood loss in the AABO and UAE groups was 17.5 (interquartile ranges [IQR]: 10, 45) and 10 (IQR: 6.25, 20) mL, respectively (P = 0.264). The body surface radiation dose of the AABO group was much lower than that of the UAE group (5.22 ± 0.44 vs. 1441.85 ± 11.59 mGy, P < 0.001). The AABO group also had lower hospitalization expenses than the UAE group (2.42 ± 0.51 vs. 3.42 ± 0.85 *10^5 yuan, P < 0.001). The average time to serum ß-hCG normalization in the AABO group was 28.9 ± 3.21 d, which was similar to that in the UAE group (30.3 ± 3.72 d, P = 0.099). In addition, the incidence of adverse events in the AABO group was lower than that in the UAE group (5.9% vs. 58.8%, P < 0.001). CONCLUSION: Prophylactic AABO was equally as effective as UAE in patients with type III CSP but was safer than UAE during and after the operation.

BACKGROUND: The aim of this systematic review and meta-analysis was to introduce the relatively novel method of ultrasound-guided local lauromacrogol injection (USG-LLI) followed by dilatation and curettage for caesarean scar pregnancy (CSP) and to investigate the clinical safety and efficacy between uterine artery embolization (UAE) and USG-LLI in the treatment of CSP. METHODS: The relevant literature and articles about USG-LLI, UAE and CSP published in eight electronic databases were searched to extract the primary outcomes for the selected articles. Review Manager Software(RevMan) V.5.2 was used for quantitative data synthesis and data analysis. Forest plots, sensitivity analysis and bias analysis were also performed on the included articles. RESULTS: Of 10 studies included in our search, 623 patients were in the USG-LLI group and 627 patients were in the UAE groups. There were no significant differences between the two groups in terms of success rate, blood loss and time to human chorionic gonadotropin (hCG) normalization. However, USG-LLI group patients than UAE group patients had a shorter duration of hospital stay (mean difference [MD] = -1.97; 95% confidence intervals [CI] -2.63 to -1.31; P < 0.05; I2 = 95%), shorter restored menses (MD = -4.84; 95%CI -5.78 to -3.90; P < 0.05; I2 = 95%), and lower complication rates [odds ratio(OR) = 0.21; 95%CI:0.15 to 0.30; P < 0.05]; and cheaper on expenses of hospitalization (MD = -8028.29; 95%CI -10,311.18 to -5745.40; P < 0.05; I2 = 100%). CONCLUSIONS: The results demonstrate that USG-LLI is comparable in curative effect and success rates with UAE in the therapy of CSP, but patients in the USG-LLI group seem to have fewer complications rates, shorter duration of hospital stays and lower costs.

A 37-old III gravida II para with two previous cesarean sections (CS) presented in 7 + 3 weeks of pregnancy with cervical ectopic pregnancy (CEP). At 12th week of pregnancy, a cerclage was performed to avoid cervical distention by the expanding placenta. Due to missing experience in CEP management and to avoid emergency operation, we recommended CS in 30th week of pregnancy due to unspecific pain of the patient. Vaginal bleeding never occured.After transverse laparotomy, the urinary bladder was sharply dissected from the anterior uterine and cervical wall. The baby was delivered by transverse cervicotomy caudally of the placenta. The placenta was left in situ. The patient then got prophylactic embolization of the uterine arteries to prevent further severe hemorrhage. 48 h later, ultrasound showed a floating, avascular placenta within a poor echogenic fluid-filled cervical space as well as macrohematuria. After re-laparotomy and cervicotomy at the same day, the placenta was completely and easily evacuated. A bladder injury was recognized and closed. We performed a cervical internal os plasty by inverting the cervical lips and suturing their distal ends on the proximal cervical tissue, resulting in complete bleeding cessation. Although, the patient got 8 erythrocyte concentrates at all, she was always in a stable condition without hemorrhagic shock.This case demonstrates for the first time a live-birth with uterus-conserving management in CEP.

OBJECTIVE: High-intensity focused ultrasound (HIFU) followed by curettage or uterine artery embolization (UAE) followed by curettage are relatively effective methods for cesarean scar pregnancy (CSP), which can provide a high success rate and repregnancy while reducing blood loss and adverse events. Therefore, we conducted this meta-analysis to evaluate the efficacy, safety, and pregnancy outcomes of HIFU groups versus UAE groups with CSP. DATA SOURCES: The PubMed, EMBASE, Cochrane, China National Knowledge Infrastructure, and Wanfang databases were systematically searched to find studies that compared the therapeutic effects of HIFU groups versus UAE groups. METHODS OF STUDY SELECTION: Our primary end points were blood loss, adverse events, success rate, and repregnancy. We implemented random-effects models or fixed-effects models to evaluate the pooled data. TABULATION, INTEGRATION, AND RESULTS: Thirty-four eligible items were included in studies. The blood loss was significantly reduced in HIFU groups compared with UAE groups (standardized mean difference = -1.45, 95% confidence interval [CI], 2.21 to -0.68; p <.001). Significantly fewer adverse events occurred in the HIFU groups than in UAE groups (odds ratio [OR] = 0.36, 95% CI, 0.23-0.57; p <.001). The success rate of HIFU groups was higher than that of UAE groups (OR = 1.56, 95% CI, 1.05-2.32; p = .03). There were more pregnancies in HIFU groups than in UAE groups (OR = 1.64, 95% CI, 1.28-2.11; p <.001). CONCLUSION: In the CSP, the effect of HIFU groups was better than that of UAE groups: less blood loss, high success rate, fewer adverse events, and favorable fertility protection. Thus, it is a promising therapeutic method for patients.

OBJECTIVE: To investigate the efficacy and safety of high-intensity focused ultrasound (HIFU) compared with uterine artery embolization (UAE) in cesarean section pregnancy (CSP) and to calculate the success rate of HIFU. DATA SOURCES: We searched PubMed, Cochrane, Scopus, Web of Science, and Embase on September 30, 2022, and the related studies were independently reviewed by 2 researchers. METHODS OF STUDY SELECTION: Medical subject headings and relevant terms from other articles were used for the database search. Patients with CSP who underwent HIFU were included in this analysis. The following results were recorded: success rate, intraoperative blood loss, time for serum beta-human chorionic gonadotropin (beta-HCG) normalization and menstruation recovery, adverse events, hospitalization time, and hospitalization expenses. We used the Newcastle-Ottawa Scale scoring system and the methodological index for nonrandomized studies system to evaluate the quality of the studies. TABULATION, INTEGRATION, AND RESULTS: Data from 6 studies were used to compare the efficacy and safety of UAE and HIFU. We pooled the success rate of HIFU by including 10 studies. No data overlap between the 10 studies. Success rate was higher in the HIFU group (odds ratio [OR] = 1.90; 95% confidence interval [CI] 1.06-3.41; p = .03; I2 = 0). We performed the meta-analysis of single rate in R 4.2.0 software, and the success rate of HIFU group was 0.94 (95% CI 0.92-0.96; p = .04; I2 = 48%). Intraoperative blood loss (mean difference [MD]= -21.94 mL; 95% CI -67.34 to 23.47; p = .34; I2 = 99%) and time for serum beta-HCG normalization (MD = 3.13 days; 95% CI 0.02-6.25; p = .05; I2 = 70%) were not significantly different. Time to menstruation recovery (MD = 2.72 days; 95% CI 1.32-4.12; p = .0001; I2 = 0) in the UAE group was shorter than that in the HIFU group. Adverse events were not significantly different between the 2 groups (OR = 0.53; 95% CI 0.22-1.29; p = .16; I2 = 81%). Hospitalization time was not significantly different between the HIFU and UAE groups (MD = -0.41 days; 95% CI -1.14 to 0.31; p = .26; I2 = 55%). Hospitalization expenses of the HIFU group were lower than those of the UAE group (MD = -7488.49 yuan; 95% CI -8460.13 to -6516.84; p <.000; I2 = 0). Heterogeneity of the time for beta-HCG normalization, adverse events, and hospitalization time were improved after excluding one study, and HIFU showed better results in the sensitivity analysis of adverse events and hospitalization time. CONCLUSION: According to our analysis, HIFU demonstrated satisfactory treatment success, accompanied by similar intraoperative blood loss, slower normalization of beta-HCG levels, and menstruation recovery, but potentially shorter hospitalization time, lower adverse events and lower costs than UAE. Therefore, HIFU is an effective, safe, and economical treatment for patients with CSP. These conclusions should be interpreted with caution because of the significant heterogeneity. However, large and strictly designed clinical trials are required to verify these conclusions.
