RESUMO
BACKGROUND: Cesarean sections are the most common abdominal surgical interventions worldwide, with increasing rates in both developed and developing countries. Postpartum (hemorrhage PPH) during cesarean sections can lead to maternal morbidity, prolonged hospital stays, and increased mortality rates. Although various non-surgical measures have been recommended for PPH prevention, surgical techniques such as uterine artery ligation and embolization have been used to manage PPH effectively. OBJECTIVE: This study aimed to evaluate the effectiveness of a surgical technique based on the temporary bilateral clamping of uterine arteries to reduce blood loss during cesarean sections. METHODS: A longitudinal prospective, randomized, controlled study was conducted with a preliminary population group of 180 patients at the University Hospital Regional de Málaga from November 2023 to January 2024. The study protocol was approved by the Ethics Committee of the Regional University Hospital of Malaga (protocol 1729-N-23 and registred with ISRCTN15307819|| http://www.isrctn.org/ , Date submitted 12 June 2023 ISRCTN 15307819). The patients were divided into two groups based on whether the clamping technique was applied during their cesarean sections. The study assessed hemoglobin levels before and after surgery, hospitalization durations, and the prevalence of anemia at discharge as the primary outcomes. RESULTS: The patients who underwent the clamping technique demonstrated significant reductions in hemoglobin differences (0.80 g/dL) compared to the control group (1.42 g/dL). The technique also resulted in shorter hospital stays (3.02 days vs. 3.90 days) and a lower prevalence of anemia at discharge (76.2% vs. 60%). CONCLUSION: Temporary clamping of uterine arteries during cesarean sections appears to be an effective measure for preventing postpartum hemorrhaging, reducing hospital stays, and decreasing the prevalence of anemia at discharge. Further research with larger sample sizes and standardized indications is warranted to confirm the benefits and potential broader applications of this technique. TRIAL REGISTRATION: ISRCTN 15,307,819.

RATIONALE: Uterine arteriovenous fistula (UAVF) is a rare vascular abnormality that can cause severe and potentially life-threatening hemorrhage. Uterine artery embolization is a common treatment that may affect ovarian and uterine perfusion and cause fertility problems. We herein report our experience treating 2 patients with UAVF who underwent resection after temporary occlusion of both internal iliac arteries. PATIENT CONCERNS: Both patients presented with a large UAVF after incomplete miscarriages in the second trimester. Magnetic resonance imaging revealed a UAVF measuring 3.6â ×â 2.6â ×â 2.1 cm over the myometrium of the posterior uterine in case 1, and a UAVF of 7.1â ×â 4.1â ×â 4.5 cm was identified in case 2. DIAGNOSIS: Uterine arteriovenous fistula, retained products of conception. INTERVENTIONS: The patients underwent resection of UAVF with temporary occlusion of the internal iliac arteries and hysteroscopic removal of the retained products of conception. OUTCOMES: Intraoperative bleeding were minimal. Neither patient exhibited abnormal uterine bleeding at the 6-month follow-up. Follow-up ultrasonography and magnetic resonance imaging showed normal uterine myometrium and endometrium and no residual disease. LESSONS: UAVF resection after temporary occlusion of the internal iliac arteries is a promising treatment approach for UAVF. This technique can reduce intraoperative bleeding and remove the potential hemorrhage-related lesion while preserving fertility.

The aim of the study was to study robotic cervical radical trachelectomy, aimed at standardizing and optimizing surgical procedures, thereby facilitating the learning process. All surgical procedures were based on the anatomy of the embryonic compartments, which not only help prevent tumor spillage due to disruption of the embryonic compartments, but also maximize the avoidance of inadequate resection margins. Using robotics to perform radical trachelectomy, combined with the concept of membrane anatomy, not only enables a bloodless surgical process, but also streamlines and simplifies the procedure, making it more efficient and precise. Utilizing robotics for radical hysterectomy can lead to a more meticulous and refined outcome. Precise surgical techniques contribute to standardizing and optimizing surgical procedures, thereby facilitating the learning process.

Performing a minimally invasive surgery comes with a significant advantage regarding rehabilitating the patient after the operation. But it also causes difficulties, mainly for the surgeon or expert who performs the surgical intervention, since only visual information is available and they cannot use their tactile senses during keyhole surgeries. This is the case with laparoscopic hysterectomy since some organs are also difficult to distinguish based on visual information, making laparoscope-based hysterectomy challenging. In this paper, we propose a solution based on semantic segmentation, which can create pixel-accurate predictions of surgical images and differentiate the uterine arteries, ureters, and nerves. We trained three binary semantic segmentation models based on the U-Net architecture with the EfficientNet-b3 encoder; then, we developed two ensemble techniques that enhanced the segmentation performance. Our pixel-wise ensemble examines the segmentation map of the binary networks on the lowest level of pixels. The other algorithm developed is a region-based ensemble technique that takes this examination to a higher level and makes the ensemble based on every connected component detected by the binary segmentation networks. We also introduced and trained a classic multi-class semantic segmentation model as a reference and compared it to the ensemble-based approaches. We used 586 manually annotated images from 38 surgical videos for this research and published this dataset.

OBJECTIVE: We investigated the efficacy of a combination of laparoscopy and bilateral uterine artery occlusion (BUAO) for the treatment of type II cesarean scar pregnancy (CSP). METHODS: Patients with type II CSP underwent laparoscopy + bilateral uterine artery embolization (control group) or laparoscopy + BUAO (study group). Data regarding the duration of surgery, intraoperative hemorrhage, postoperative complications, the duration of the hospital stay, and the costs of hospitalization were retrospectively collected. One year later, the time to the return of the ß-human chorionic gonadotropin (ß-hCG) concentration to normal and to the return of menstruation were compared. RESULTS: The duration of surgery, time to the return of menstruation, and incidence of postoperative complications in the study group were significantly less than in the control group, but there was no significant difference in the time for ß-hCG to return to normal or the volume of intraoperative hemorrhage. The duration of hospitalization and costs for the control group were higher than those for the study group. CONCLUSION: Laparoscopy in combination with BUAO is associated with minimal trauma, rapid recovery, a short duration of surgery, low cost of hospitalization, and a low postoperative complication rate. Thus, it represents a useful new surgical treatment for type II CSP.

The objective of this article is to compare the amount of intraoperative blood loss during laparoscopic myomectomy when performing bilateral transient clamping of the uterine and utero-ovarian arteries versus no intervention. It´s a randomized controlled prospective study carried out in the Department of Obstetrics and Gynecology Ramón y Cajal University Hospital and HM Montepríncipe-Sanchinarro University Hospital, Madrid, Spain, in women with fibroid uterus undergoing laparoscopic myomectomy. Eighty women diagnosed with symptomatic fibroid uterus were randomly assigned to undergo laparoscopic myomectomy without additional intervention (Group A) or temporary clamping of bilateral uterine and utero-ovarian arteries prior to laparoscopic myomectomy (Group B). Estimated blood loss, operating time, length of hospital stay, and postoperative hemoglobin values were compared in both groups. The number of fibroids removed was similar in both groups (p = 0.77). Estimated blood loss was lower in the group of patients with prior occlusion of uterine arteries (p = 0.025) without increasing operating time (p = 0.17) nor length of stay (p = 0.17). No patient had either intra or postoperative complications. Only two patients (2.5%) required blood transfusion after surgery. We conclude that temporary clamping of bilateral uterine arteries prior to laparoscopic myomectomy is a safe intervention that reduces blood loss without increasing operative time.

OBJECTIVE: To describe a retroperitoneal transient occlusion of the uterine or internal iliac artery in conjunction with a high-risk evacuation of products of conception. The procedure was performed vaginally, minimally invasively, via vaginal natural orifice transluminal endoscopic surgery. DESIGN: Description of the surgical technique using original video footage. This study was exempted from requiring hospital institutional review board approval. SETTING: Teaching hospital. PATIENT(S): A 34-year-old woman (G8P3) with a medical history of 2 cesarean sections, 1 partial mole, and a missed abortion with 2.8 L of blood loss. The patient presented after 10 weeks of amenorrhea. Ultrasound revealed a large blood-filled niche in the cesarean section scar with a thin overlying myometrium. A partial mole was suspected as well as increased vascularization in the myometrium and enhanced myometrial vascularity with arterial flow velocities of 100 cm/s. A risk of heavy blood loss in conjunction with curettage was anticipated. The patient had a strong preference for a fertility-preserving treatment, and after informed consent, she opted for transient occlusion of the uterine arteries with subsequent suction evacuation of the molar pregnancy. The patient signed a consent form accepting the procedure. The patient included in this video provided consent for publication of the video and posting of the video online including social media, the journal website, and scientific literature websites. Institutional review board approval was not required in accordance with the IDEAL guidelines. INTERVENTION(S): A vaginal incision was made over the bladder, and the vaginal mucosa was dissected. The paravesical space was dissected over the arcus tendinous, and the pelvic retroperitoneal space was opened. A small (7 cm) GelPOINT V-Path (Applied Medical, Rancho Santa Margarita, California) was inserted into the obturator fossa and insufflated with 10 CO2 mm Hg. Standard laparoscopic instruments were used through the gel port. Under endoscopic view, dissection to the right obturator fossa and iliac vessels was made, and the internal iliac artery was identified. A removable clip was placed on the origin of the right uterine artery. The same procedure was performed on the left side where the internal iliac artery was clipped. Different vessels were clipped to demonstrate and investigate the feasibility of both approaches. Both vessels were equally accessible. Care should be taken not to injure the uterine vein at the time of clipping. Dilation and evacuation was performed under transanal ultrasound surveillance. When hemostatic control was assured, first, the right clip was removed from the iliac artery. Hemostatic control was ensured, and after 10 minutes, the second clip on the left iliac artery was removed. The GelPOINT was removed, and the vaginal incision was sutured. The patient bled in total 500 mL. MAIN OUTCOME MEASURE(S): Not applicable. RESULT(S): The patient recovered swiftly without complications. Pathology confirmed a partial molar pregnancy. CONCLUSION(S): Uterine or internal iliac artery ligation can be lifesaving in situations with massive bleeding from the uterus. Current minimally invasive approaches are laparoscopic vessel ligation and, more commonly, uterine artery embolization, which has unclear impact on fertility and has shown an increased risk of intrauterine growth restriction, miscarriage, and prematurity. As the patient was undergoing a vaginal evacuation of pregnancy, a vaginal and retroperitoneal approach of artery ligation was deemed least invasive. In patients with fertility-preserving wishes, care should to be taken to avoid as much trauma as possible to the endometrium. Optimized blood control, and a shorter duration of using a curette, may potentially reduce the risk of endometrial damage. We present a novel minimally invasive approach via vaginal natural orifice transluminal endoscopic surgery-retroperitoneal transient occlusion of the internal iliac or uterine artery. The whole procedure can be performed by the operating gynecologist, and the occlusion is transient and can be reversed in a stepwise controlled manner.

AIM: To compare intraoperative and postoperative clinical results of laparoscopic and laparotomic myomectomy operations in patients with and without bilateral uterine artery ligation. MATERIALS AND METHODS: A retrospective analysis of 217 patients with intramural ≥ 5 cm myoma who underwent laparoscopic (n = 100) or laparatomic (n = 117) myomectomy was conducted. The patients were grouped according to the number of uterine myomas removed (≤2 or > 2). Clinical results of both laparoscopic and laparotomic myomectomy methods and the presence of uterine artery ligation were compared. The recurrence of myomas and pregnancy outcomes were also reported. RESULTS: For patients with > 2 myomas removed without uterine artery ligation, the amount of bleeding, operation time, and hospital stay were significantly lower in patients who underwent laparotomic myomectomy but no significant difference in patients with <2 myomas removed. The rate of hemorrhage was lower in both the laparoscopy and laparotomy uterine artery ligation groups. The recurrence rate of myomas ≤ 3 cm was higher in the laparoscopic myomectomy group (p = .022) and in patients without uterine artery ligation group (p = .028) but recurrence rates for myomas > 3 cm were similar between in groups. Pregnancy occurred in 24 of the 96 patients who underwent uterine artery ligation, and 14 pregnancies resulted in live births. CONCLUSION: Uterine artery ligation might be a suitable addition to myomectomy surgery to reduce intraoperative bleeding and the recurrence of myoma, especially in cases where more than two uterine myomas are removed laparoscopically. KEY WORDS: Laparoscopic myomectomy, Laparotomic myomectomy, Myomas, Haemorrhage, Uterine artery ligation.

Large loop excision of the transformation zone is an extremely common procedure routinely carried out in a gynaecology or colposcopy outpatient setting under local anaesthetic. Here, we present a rare case resulting in emergency hysterectomy. A healthy para 3, who had been diagnosed with microscopic cancer of the cervix, attended colposcopy for repeat excision. The colposcopy revealed a normal cervix, and diathermy loop excision was performed. During the procedure, heavy bleeding from the anterior cutting edge was noted. Despite the best attempts to manage the haemorrhage conservatively in outpatients, the bleeding persisted, and the patient was transferred to theatres. Examination under anaesthesia revealed an injury to the descending branch of the uterine artery, and emergency hysterectomy was performed. Immediate recognition of an extremely rare complication, fast decision-making and a cross-disciplinary approach led to a satisfactory outcome.

RATIONALE: Uterine artery spontaneous rupture is a rare but potentially life-threatening complication during pregnancy and puerperium. The lack of typical symptoms makes it difficult to diagnose, which can result in serious consequences for both the mother and fetus. PATIENT CONCERNS: Case 1 presented with fainting and lower abdominal discomfort, while Case 2 developed hypotension after delivery and remained in poor condition even after rehydration. DIAGNOSES: Both cases were diagnosed with uterine artery spontaneous rupture, with intraoperative findings revealing ruptures in different branches of the uterine artery. INTERVENTIONS: Both cases underwent surgical interventions, with laparoscopic surgery performed in Case 1 and repair of the ruptured artery in Case 2. OUTCOMES: Both cases had successful outcomes, with the ruptured arteries repaired and the patients discharged from the hospital within a week after surgery. LESSONS: Uterine artery spontaneous rupture is a rare but potentially life-threatening complication that may present with atypical symptoms. Early diagnosis and prompt surgical intervention are crucial in preventing serious complications for both the mother and fetus. Clinicians should maintain a high level of suspicion for this condition when evaluating patients presenting with unexplained symptoms or signs of peritoneal irritation during pregnancy and puerperium.

BACKGROUND: Transcervical resection of adhesion (TCRA) and postoperative adjuvant estrogen and progestin are the main treatments for cavity adhesions, but the recurrence rate after surgery is still high. It was showed that aspirin could promote endometrial proliferation and repair after TCRA in patients with severe cavity adhesions, but the effect on reproduction was uncertain. OBJECTIVE: To assess the effect of aspirin on uterine arterial blood flow and endometrium in moderate and severe intrauterine adhesion after transcervical resection of adhesion. METHODS: The databases used included Cumulative Index to PubMed, EMBASE, Chinese National Knowledge Infrastructure (CNKI), and Wanfang database. Studies published before June 2022 were included. Each participant received an aspirin-based intervention aimed at improving uterine status, which was compared to a sham intervention. The primary outcome measure was a change in endometrium thickness. Secondary outcomes included uterine artery resistance index, blood flow index, and endometrial arterial resistance index. RESULT: A total of 19 studies (n = 1361 participants) that met the inclusion criteria were included in this study. The aspirin-based intervention was strongly associated with better clinical outcome at second-look endometrium thickness (MD 0.81, CI 0.46-1.16; p < .00001) and blood flow Index (FI) (MD 4.1, CI 2.3-5.9; p < .00001). Besides, the analysis of arterial pulsatility index (PI) showed a significantly reduced after transcervical resection of adhesion (MD -0.9, CI -1.2 to 0.6; p < .00001); whereas no significant difference was found in endometrial arterial resistance index (RI) (95% CI, -0.30 to 0.01; p = .07). CONCLUSION: Our study proved the effect of aspirin on uterine arterial blood flow and endometrium in moderate and severe intrauterine adhesion after transcervical resection of adhesion. However, the review requires evidence from additional randomized controlled trials and high-quality research. More strictly designed research studies are needed to assess the effectiveness of aspirin administration after transcervical resection of adhesion.

OBJECTIVES: The present study aimed to investigate the efficacy of ultrasonic dissectors for adenomyomectomy using the double/multiple-flap method combined with temporary occlusion of the temporary bilateral uterine artery and the utero-ovarian vessels for the treatment of symptomatic adenomyosis. DESIGN: This was a retrospective study. PARTICIPANTS: In total, 162 patients with symptomatic adenomyosis were included, and all of them had originally been scheduled to group A (n = 82) and group B (n = 80) with each group representing a different surgical application. All eligible women were informed of the potential complications, benefits, and alternatives of each approach before they were assigned to one of the two groups, and patients chose group A or group B by themselves. In group A, we performed laparoscopic ultrasonic dissectors in adenomyosis with the double/multiple-flap method combined with temporary occlusion of the bilateral uterine artery and utero-ovarian vessels, while in group B, we performed adenomyomectomy with scissors. During the period of treatment, we evaluated operative time, intraoperative blood loss, and the degree of fatigue of surgeons' fingers. RESULTS: The estimated blood loss, operative time, and the degree of fatigue of surgeons' fingers in group A were significantly lower than that in group B (p < 0.001). No serious perioperative complications were observed in either group. LIMITATIONS: This was a retrospective study. CONCLUSION: The use of ultrasonic dissectors in laparoscopic adenomyomectomy with temporary occlusion of the bilateral uterine artery and the utero-ovarian vessels leads to improvements and releases the fatigue of surgeons' fingers in laparoscopic adenomyomectomy.

Background: The proximity of the uterus and the cervix to the urinary tract predisposes the latter to injury during obstetrical and gynaecological surgical procedures. Following a difficult surgical procedure on the lower uterine segment and or adnexa, urinary tract injury should be excluded. Methods: A booked 39-year-old G3P2 lady who suffered an ischaemic stroke in the index pregnancy had a caesarean delivery at 39 weeks of gestation and sustained an extensive tear that extended inferiorly on the left lateral aspect of the uterus and this resulted in postpartum haemorrhage. Following the repair of the tear, uterine artery ligation was performed to achieve haemostasis. Results: Postoperatively, conventional ultrasonography which was performed to exclude ureteric injury suggested left hydronephrosis and a preliminary report of computerized tomography (CT) showed the same finding. The patient subsequently had left ureteric stenting. The final report of the CT scan was delayed but showed a simple left renal cyst and no hydronephrosis. Conclusion: Renal cyst is a differential diagnosis of hydronephrosis. Delayed availability of the final result of medical investigations jeopardises patients' safety. A preliminary imaging report is prone to error and its use to determine the indication for an invasive procedure should be limited to emergencies.

STUDY OBJECTIVE: To demonstrate the "trick" knot, a technique of temporary ligation of the uterine artery at origin, a modification of the previously published "shoelace" knot. DESIGN: A video demonstration. SETTING: A private hospital. INTERVENTION: Bilateral uterine arteries at origin are exposed after dissection of the peritoneum over the triangle formed by the round ligament, the infundibulopelvic ligament, and the pelvic sidewall [Video 1]. A 60-cm long free polyglactin absorbable suture with preformed knots at each end is introduced around the skeletonized uterine artery. Using a single throw, the "trick" knot is made by pulling out a loop of thread. The end is cut short, and the same suture is used to similarly ligate the other uterine artery. Each knot thus formed has a free end and a knotted end. Laparoscopic myomectomy is performed. On completion of the procedure, the knot is released by pulling the free end, restoring the blood supply to the uterus. CONCLUSION: Bilateral uterine artery ligation, although an effective method to curb bleeding during a laparoscopic myomectomy, when performed permanently, may lead to undesirable outcomes in women who wish to preserve fertility [1-3]. Methods for temporary ligation of the uterine artery at origin, such the removable vascular clips, are thus regarded justifiable [4]. In contrast to the removable "shoelace" knot, which uses a loop to make a throw, the technique of performing the "trick" knot mimics the steps of forming a regular intracorporeal knot [5]. This makes the latter technically easier and hence faster to perform, while still being as economic and reproducible as the former.

BACKGROUND AND OBJECTIVES: Lateral occlusion prior to TLH has been suggested to reduce perioperative bleeding, operative time, and hospital stay. Furthermore, reducing the amount of bleeding and the length of the operation may affect parameters such as postoperative pain and the number of patients with postoperative vaginal vault hematoma. METHODS: This RCT was conducted at a single center at Odense University Hospital in Denmark. Between February 2016 and February 2019, a total of 58 patients undergoing TLH and bilateral salpingectomy for benign cases were recruited to the study. RESULTS: The mean operating time was significantly longer in the LA group with a mean difference between the two groups of six minutes. No other discrepancy regarding the primary outcomes was observed between the two groups. Total blood loss was similar in the two groups as well as the average hospital stay and the VAS score during the first seven days. 93% of the patients were discharged from the hospital within the first 24 h postoperatively. CONCLUSION: This RCT demonstrates that lateral occlusion of the uterine artery prior to TLH does not improve outcome for the patients and should therefore not be used as a standard procedure.

STUDY OBJECTIVE: To demonstrate a laparoscopic technique to remove a scar pregnancy. DESIGN: Stepwise demonstration of the surgical technique. SETTING: Santa Croce and Carle Hospital, Cuneo. INTERVENTION: Patient B.B. is a woman referred to our center for a suspected cesarean scar pregnancy (CSP) at 9 weeks gestation. CSP occurs approximately in 6% of all ectopic pregnancies. The estimated incidence is reported to be 1:1800 to 1:2500 in cesarean deliveries. Depending on its location, CSP can be categorized as either type 1, if the growth is in the uterine cavity, or type 2, if it expands toward the bladder and the abdominal cavity. If inadequately managed, it can lead to severe complications; most of them are hemorrhagic and can threaten the woman's life. There are several therapeutic approaches: local excision seems to be the most effective choice in type 2 CSP. In expert hands, the laparoscopic approach is perhaps the best surgical choice as tissue dissection, electrosurgical hemostasis, and vascular control can be effectively managed with minimal invasive access. Because severe intraoperative bleeding can occur, retroperitoneal vascular control is mandatory in this surgery. In type 1 CSP curettage, aspiration or hysteroscopic approach can be considered if the CSP is of small dimensions. A hysteroscopic approach can also be helpful in type 2 CSP during the laparoscopic removal, as intrauterine guidance. A potassium chloride local injection can be considered in a preoperative stage in the presence of a fetal heart rate. The systemic administration of methotrexate is usually ineffective as single agent, but it can be useful if administered as adjuvant therapy. Uterine artery embolization can be useful in an emergency setting to manage severe bleeding, but it can lead to complications in subsequent pregnancies and, more rarely, to premature ovarian failure. Considering poor bleeding at presentation, feasible dimensions, and the woman's desire for future pregnancy, ultrasound-guided aspiration and curettage was attempted. Because endouterine removal was incomplete, methotrexate injection was proposed as adjuvant therapy, but the administration was postponed as the patient tested positive for coronavirus disease 2019. A month later, beta-human chorionic gonadotropin level dropped from over 16 000 to 271 mU/mL, so an ultrasound and biochemical follow-up was performed. A month later, despite a low beta-human chorionic gonadotropin value, an increase in dimensions was observed at ultrasound, so surgical laparoscopic removal was offered. In this video article, laparoscopic removal of scar pregnancy is discussed in the following surgical steps: (1) Temporary closure of uterine arteries at the origin, using removable clips. (2) Retroperitoneal dissection to safely manage the scar pregnancy. (3) Dissection of the myometrial-pregnancy interface. (4) Double layer suture on the anterior uterine wall. CONCLUSION: Laparoscopic surgical management is a very effective surgical approach to remove CSP. Knowledge of retroperitoneal dissection and vascular control is necessary to carry out this surgical intervention safely and effectively.

Objective: To investigate the efficacy of uterine artery ligation (UAL) and uterine artery embolization (UAE) in the treatment of uterine asthenia postpartum hemorrhage (PPH) after cesarean section and its effect on uterine and ovarian artery blood flow and function. Methods: 100 patients with uterine asthenia PPH after cesarean section in our hospital from January 2018 to November 2020 were randomly divided into 50 cases in the UAL group and 50 cases in the UAE group. They were followed up for 12 months. The bleeding volume, operation time, immediate hemostasis rate, and hemostasis effective rate; lochia clearance time and menstrual rehydration time; RI and S/D; and serum FSH, E2, and LH levels were compared between the two groups. Results: Compared with the UAL group, the amount of bleeding in the UAE group was significantly increased and the operation time was significantly shortened (p < 0.05). There was no significant difference in the immediate hemostatic rate and hemostatic effective rate between the two groups (p > 0.05). There was no significant difference in lochia clearance time and menstrual rehydration time between the two groups (p > 0.05). There was no significant difference in RI and S/D between the two groups (p > 0.05). Compared with before the operation, the levels of FSH and LH in the two groups decreased significantly, and the level of E2 increased significantly (p < 0.05). There was no significant difference between the two groups (p > 0.05). Conclusion: The efficacy of UAL and UAE in the treatment of PPH with uterine asthenia after cesarean section and its effect on the blood flow and function of uterine and ovarian arteries are equivalent, but the amount of bleeding in UAL is less and the operation time of UAE is shorter. The appropriate operation method can be selected according to the actual situation.

OBJECTIVES: Post-partum hemorrhage (PPH) continues to be the leading cause of maternal mortality in low-resource settings. The commonest variant - Atonic PPH, is managed by additional pharmacological measures which may fail. Additional surgical interventions for hemostasis take time and are not universally available. Immediate arrest of bleeding was deemed essential and a novel Transvaginal Uterine Artery Clamp (TVUAC) was explored for its effectiveness in achieving immediate hemostasis in atonic and mixed post-partum hemorrhage. STUDY DESIGN: A retrospective chart review was performed for all patients, who underwent vaginal delivery and developed immediate post-partum atonic PPH, in a tertiary care center in South India, between 1st April 2015 and 31st December 2020. As soon as excess bleeding was observed, two TVUACs were applied trans-vaginally at 3' and 9'o clock position of the cervix to occlude the uterine arteries where it joins the isthmus of the uterus. RESULTS: Of 3999 vaginal deliveries, there were 251 patients who developed primary atonic PPH during the study period, of which 89 were managed by medical measures alone. Out of the remaining 162 patients, in 153 (94.4%) TVUAC helped to achieve hemostasis; with TVUAC alone in 120 patients (78.43%) and with an additional second line surgical intervention in 33 patients. In nine patients, TVUAC was not readily available and hence second line interventions alone were used. None required any third line surgical interventions (laparotomies) for hemostasis nor were there any incident of maternal mortality or consumptive coagulopathy. TVUAC was applied for a mean duration of 25 ± 10 min. Only 11.6% (29/251, 95% C.I 7.9-16.1%) of the patients required a blood transfusion with a median of 2 (1-4) units of packed RBC. No procedure related complications were reported up to a scheduled 6th week in-person follow-up. CONCLUSION: The novel TVUAC shows potential in limiting third line interventions, maternal morbidity and mortality. Its effectiveness and safety may be further explored as a first line surgical adjunct to medical measures, in PPH protocols in low-resource settings.
