RESUMO
OBJECTIVE: To assess (i) clinical and pregnancy characteristics, (ii) patterns of surgical procedures, and (iii) surgical morbidity associated with cesarean hysterectomy for placenta accreta spectrum based on the specialty of the attending surgeon. METHODS: The Premier Healthcare Database was queried retrospectively to study patients with placenta accreta spectrum who underwent cesarean delivery and concurrent hysterectomy from 2016 to 2020. Surgical morbidity was assessed with propensity score inverse probability of treatment weighting based on surgeon specialty for hysterectomy: general obstetrician-gynecologists, maternal-fetal medicine specialists, and gynecologic oncologists. RESULTS: A total of 2240 cesarean hysterectomies were studies. The most common surgeon type was general obstetrician-gynecologist (n = 1534, 68.5%), followed by gynecologic oncologist (n = 532, 23.8%) and maternal-fetal medicine specialist (n = 174, 7.8%). Patients in the gynecologic oncologist group had the highest rate of placenta increta or percreta, followed by the maternal-fetal medicine specialist and general obstetrician-gynecologist groups (43.4%, 39.6%, and 30.6%, P < .001). In a propensity score-weighted model, measured surgical morbidity was similar across the three subspecialty groups, including hemorrhage / blood transfusion (59.4-63.7%), bladder injury (18.3-24.0%), ureteral injury (2.2-4.3%), shock (8.6-10.5%), and coagulopathy (3.3-7.4%) (all, P > .05). Among the cesarean hysterectomy performed by gynecologic oncologist, hemorrhage / transfusion rates remained substantial despite additional surgical procedures: tranexamic acid / ureteral stent (60.4%), tranexamic acid / endo-arterial procedure (76.2%), ureteral stent / endo-arterial procedure (51.6%), and all three procedures (55.4%). Tranexamic acid administration with ureteral stent placement was associated with decreased bladder injury (12.8% vs 23.8-32.2%, P < .001). CONCLUSION: These data suggest that patient characteristics and surgical procedures related to cesarean hysterectomy for placenta accreta spectrum differ based on surgeon specialty. Gynecologic oncologists appear to manage more severe forms of placenta accreta spectrum. Regardless of surgeon's specialty, surgical morbidity of cesarean hysterectomy for placenta accreta spectrum is significant.

INTRODUCTION: Since malignancy during pregnancy is uncommon, information regarding contraception selection or sterilization at delivery is limited. The objective of this study was to examine the type of long-acting reversible contraception or surgical sterilization procedure chosen by pregnant patients with malignancy at delivery. MATERIAL AND METHODS: This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample in the USA. The study population was vaginal and cesarean deliveries in a hospital setting from January 2017 to December 2020. Pregnant patients with breast cancer (n = 1605), leukemia (n = 1190), lymphoma (n = 1120), thyroid cancer (n = 715), cervical cancer (n = 425) and melanoma (n = 400) were compared with 14 265 319 pregnant patients without malignancy. The main outcome measures were utilization of long-acting reversible contraception (subdermal implant or intrauterine device) and performance of permanent surgical sterilization (bilateral tubal ligation or bilateral salpingectomy) during the index hospital admission for delivery, assessed with a multinomial regression model controlling for clinical, pregnancy and delivery characteristics. RESULTS: When compared with pregnant patients without malignancy, pregnant patients with breast cancer were more likely to proceed with bilateral salpingectomy (adjusted odds ratio [aOR] 2.30) or intrauterine device (aOR 1.91); none received the subdermal implant. Pregnant patients with leukemia were more likely to choose a subdermal implant (aOR 2.22), whereas those with lymphoma were more likely to proceed with bilateral salpingectomy (aOR 1.93) and bilateral tubal ligation (aOR 1.76). Pregnant patients with thyroid cancer were more likely to proceed with bilateral tubal ligation (aOR 2.21) and none received the subdermal implant. No patients in the cervical cancer group selected long-acting reversible contraception, and they were more likely to proceed with bilateral salpingectomy (aOR 2.08). None in the melanoma group chose long-acting reversible contraception. Among pregnant patients aged <30, the odds of proceeding with bilateral salpingectomy were increased in patients with breast cancer (aOR 3.01), cervical cancer (aOR 2.26) or lymphoma (aOR 2.08). The odds of proceeding with bilateral tubal ligation in pregnant patients aged <30 with melanoma (aOR 5.36) was also increased. CONCLUSIONS: The results of this nationwide assessment in the United States suggest that among pregnant patients with malignancy, the preferred contraceptive option or method of sterilization at time of hospital delivery differs by malignancy type.

PURPOSE: To examine feto-maternal characteristics and outcomes of morbidly obese pregnant patients who conceived with assisted reproductive technology (ART). METHODS: This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample. Study population was 48,365 patients with ART pregnancy from January 2012 to September 2015, including non-obesity (n = 45,125, 93.3%), class I-II obesity (n = 2445, 5.1%), and class III obesity (n = 795, 1.6%). Severe maternal morbidity at delivery per the Centers for Disease and Control Prevention definition was assessed with multivariable binary logistic regression model. RESULTS: Patients in the class III obesity group were more likely to have a hypertensive disorder (adjusted-odds ratio (aOR) 3.03, 95% confidence interval (CI) 2.61-3.52), diabetes mellitus (aOR 3.08, 95%CI 2.64-3.60), large for gestational age neonate (aOR 3.57, 95%CI 2.77-4.60), and intrauterine fetal demise (aOR 2.03, 95%CI 1.05-3.94) compared to those in the non-obesity group. Increased risks of hypertensive disease (aOR 1.35, 95%CI 1.14-1.60) and diabetes mellitus (aOR 1.39, 95%CI 1.17-1.66) in the class III obesity group remained robust even compared to the class I-II obesity group. After controlling for priori selected clinical, pregnancy, and delivery factors, patients with class III obesity were 70% more likely to have severe maternal morbidity at delivery compared to non-obese patients (8.2% vs 4.4%, aOR 1.70, 95%CI 1.30-2.22) whereas those with class I-II obesity were not (4.1% vs 4.4%, aOR 0.87, 95%CI 0.70-1.08). CONCLUSIONS: The results of this national-level analysis in the United States suggested that morbidly obese pregnant patients conceived with ART have increased risks of adverse fetal and maternal outcomes.

Placenta accreta spectrum encompasses cases where the placenta is morbidly adherent to the myometrium. Placenta percreta, the most severe form of placenta accreta spectrum (grade 3E), occurs when the placenta invades through the myometrium and possibly into surrounding structures next to the uterine corpus. Maternal morbidity of placenta percreta is high, including severe maternal morbidity in 82.1% and mortality in 1.4% in the recent nationwide U.S. statistics. Although cesarean hysterectomy is commonly performed for patients with placenta accreta spectrum, conservative management is becoming more popular because of reduced morbidity in select cases. Treatment of grade 3E disease involving the urinary bladder, uterine cervix, or parametria is surgically complicated due to the location of the invasive placenta deep in the maternal pelvis. Cesarean hysterectomy in this setting has the potential for catastrophic hemorrhage and significant damage to surrounding organs. We propose a step-by-step schema to evaluate cases of grade 3E disease and determine whether immediate hysterectomy or conservative management, including planned delayed hysterectomy, is the most appropriate treatment option. The approach includes evaluation in the antenatal period with ultrasound and magnetic resonance imaging to determine suspicion for placenta previa percreta with surrounding organ involvement, planned cesarean delivery with a multidisciplinary team including experienced pelvic surgeons such as a gynecologic oncologist, intra-operative assessment including gross surgical field exposure and examination, cystoscopy, and consideration of careful intra-operative transvaginal ultrasound to determine the extent of placental invasion into surrounding organs. This evaluation helps decide the safety of primary cesarean hysterectomy. If safely resectable, additional considerations include intra-operative use of uterine artery embolization combined with tranexamic acid injection in cases at high risk for pelvic hemorrhage and ureteral stent placement. Availability of resuscitative endovascular balloon occlusion of the aorta is ideal. If safe resection is concerned, conservative management including planned delayed hysterectomy at around 4 weeks from cesarean delivery in stable patients is recommended.

INTRODUCTION: This study examined obstetric outcomes in patients diagnosed with uterine adenomyosis. MATERIAL AND METHODS: This historical cohort study queried the Healthcare Cost and Utilization Project's National Inpatient Sample. The study population was all hospital deliveries in women aged 15-54 years between January 2016 and December 2019. The exposure was a diagnosis of uterine adenomyosis. The main outcome measures were obstetric characteristics, including placenta previa, placenta accreta spectrum, and placental abruption. Secondary outcomes were delivery complications including severe maternal morbidity. Analytic steps to assess these outcomes included (i) a 1-to-N propensity score matching to mitigate and balance prepregnancy confounders to assess obstetric characteristics, followed by (ii) an adjusting model with preselected pregnancy and delivery factors to assess maternal morbidity. Sensitivity analyses were also performed with restricted cohorts to account for prior uterine scar, uterine myoma, and extra-uterine endometriosis. RESULTS: After propensity score matching, 5430 patients with adenomyosis were compared to 21 720 patients without adenomyosis. Adenomyosis was associated with an increased odds of placenta accreta spectrum (adjusted-odds ratio [aOR] 3.07, 95% confidence interval [CI] 2.01-4.70), placenta abruption (aOR 3.21, 95% CI: 2.60-3.98), and placenta previa (aOR 5.08, 95% CI: 4.25-6.06). Delivery at <32 weeks of gestation (aOR 1.48, 95% CI: 1.24-1.77) and cesarean delivery (aOR 7.72, 95% CI: 7.04-8.47) were both increased in women with adenomyosis. Patients in the adenomyosis group were more likely to experience severe maternal morbidity at delivery compared to those in the nonadenomyosis group (aOR 1.86, 95% CI: 1.59-2.16). Results remained robust in the aforementioned several sensitivity analyses. CONCLUSIONS: This national-level analysis suggests that a diagnosis of uterine adenomyosis is associated with an increased risk of placental pathology (placenta accreta spectrum, placenta abruption, and placental previa) and adverse maternal outcomes at delivery.

OBJECTIVE: Surgery for placenta accreta spectrum is associated with significant maternal morbidity and mortality. The role of gynecologic oncologists in the surgical management of placenta accreta spectrum is currently under investigation. This study examined the practices, experiences, and interests of gynecologic oncologists in placenta accreta spectrum surgeries. METHODS: The intervention was an anonymous, cross-sectional, 20-question survey sent to 1084 members of the Society of Gynecologic Oncology in the USA. RESULTS: A total of 184 gynecologic oncologists responded to the survey (response rate 17.0%). Most participating gynecologic oncologists have been practicing for >10 years after fellowship (53.2%), practice in urban-teaching hospitals (84.8%) with delivery volumes ≥3000/year (54.3%), and have a multidisciplinary approach (82.5%). Three-quarters (78.7%) feel that the rate of placenta accreta spectrum is increasing over time. One-third (35.5%) perform ≥6 hysterectomies for placenta accreta spectrum yearly. Less than half (45.5%) practice conservative management. Approximately half are involved from the beginning of the case (49.7%) and perform the surgery in the main operating room (59.4%). Almost three-quarters (71.6%) have experienced surgical blood loss >5 L and one-third (36.6%) have experienced cases with blood loss >10 L. About half (50.3%) of participants are interested in placenta accreta spectrum surgery for future practice. Gynecologic oncologists engaging in a multidisciplinary approach are more likely to practice in an urban-teaching hospital, have higher surgical volume, be involved from the beginning of the case, and be interested in placenta accreta spectrum surgery. Those >10 years post-training and in the Southern US region are more likely to practice conservative management or delayed hysterectomy. CONCLUSION: This society-based cross-sectional survey suggests that gynecologic oncologists are actively involved in the surgical management of placenta accreta spectrum in the USA. Nearly half of gynecologic oncologists who responded to the survey expressed interest in surgery for placenta accreta spectrum.

PURPOSE: To examine trends, characteristics, and outcomes of women with placenta percreta who had conservative management at cesarean delivery (CD) without hysterectomy. METHODS: This is a retrospective cohort study querying the National Inpatient Sample. The Study population was comprised of women with diagnosis of placenta percreta who underwent CD from 10/2015-12/2018. Characteristics and surgical outcome of women who had hysterectomy at time of CD were compared to those who did not (conservative management) in multivariable analysis. RESULTS: A total of 1055 cases were examined, of which 790 (74.9%) received hysterectomy at CD and the remaining 265 (25.1%) had conservative management without hysterectomy. During the study period, performance of hysterectomy at CD increased from 71.4% to 93.8% (P < 0.001). In multivariable analysis, more recent cases of CD for placenta percreta were less likely to have conservative management [adjusted-odds ratio (aOR) per year-quarter 0.93, 95% confidence interval (CI) 0.89-0.97]. In contrast, hospitals with small-medium bed capacity (aOR 1.72, 95% CI 1.18-2.51), non-urban teaching setting (aOR 1.76, 95% CI 1.14-2.70), and located in the Midwest (aOR 2.55, 95% CI 1.56-4.17) were more likely to offer conservative management at CD. Later gestational age was also associated with a higher likelihood of conservative management (median gestational age, 36 versus 34 weeks, P < 0.001). Women in the conservative management group experienced lower measured surgical morbidity during the admission compared to those in the cesarean hysterectomy group (47.2% versus 75.9%, aOR 0.35, 95% CI 0.26-0.48). CONCLUSION: The clinical practice for placenta percreta appears to be shifting to upfront hysterectomy at the time of CD.

BACKGROUND: Although an infrequent occurrence, the placenta can adhere abnormally to the gravid uterus leading to significantly high maternal morbidity and mortality during cesarean delivery. Contemporary national statistics related to a morbidly adherent placenta, referred to as placenta accreta spectrum, are needed. OBJECTIVE: This study aimed to examine national trends, characteristics, and perioperative outcomes of women who underwent cesarean delivery for placenta accreta spectrum in the United States. STUDY DESIGN: This is a population-based retrospective, observational study querying the National Inpatient Sample. The study cohort included women who underwent cesarean delivery from October 2015 to December 2017 and had a diagnosis of placenta accreta spectrum. The main outcome measures were patient characteristics and surgical outcomes related to placenta accreta spectrum assessed by the generalized estimating equation on multivariable analysis. The temporal trend of placenta accreta spectrum was also assessed by linear segmented regression with log transformation. RESULTS: Of 2,727,477 cases who underwent cesarean delivery during the study period, 8030 (0.29%) had the diagnosis of placenta accreta spectrum. Placenta accreta was the most common diagnosis (n=6205, 0.23%), followed by percreta (n=1060, 0.04%) and increta (n=765, 0.03%). The number of placenta accreta spectrum cases increased by 2.1% every quarter year from 0.27% to 0.32% (P=.004). On multivariable analysis, (1) patient demographics (older age, tobacco use, recent diagnosis, higher comorbidity, and use of assisted reproductive technology), (2) pregnancy characteristics (placenta previa, previous cesarean delivery, breech presentation, and grand multiparity), and (3) hospital factors (urban teaching center and large bed capacity hospital) represented the independent characteristics related to placenta accreta spectrum (all, P<.05). The median gestational age at cesarean delivery was 36 weeks for placenta accreta and 34 weeks for both placenta increta and percreta vs 39 weeks for non-placenta accreta spectrum cases (P<.001). On multivariable analysis, cesarean delivery complicated by placenta accreta spectrum was associated with increased risk of any surgical morbidities (78.3% vs 10.6%), Centers for Disease Control and Prevention-defined severe maternal morbidity (60.3% vs 3.1%), hemorrhage (54.1% vs 3.9%), coagulopathy (5.3% vs 0.3%), shock (5.0% vs 0.1%), urinary tract injury (8.3% vs 0.2%), and death (0.25% vs 0.01%) compared with cesarean delivery without placenta accreta spectrum. When further analyzed by subtype, cesarean delivery for placenta increta and percreta was associated with higher likelihood of hysterectomy (0.4% for non-placenta accreta spectrum, 45.8% for accreta, 82.4% for increta, 78.3% for percreta; P<.001) and urinary tract injury (0.2% for non-placenta accreta spectrum, 5.2% for accreta, 11.8% for increta, 24.5% for percreta; P<.001). Moreover, women in the placenta increta and percreta groups had markedly increased risks of surgical mortality compared with those without placenta accreta spectrum (increta, odds ratio, 19.9; and percreta, odds ratio, 32.1). CONCLUSION: Patient characteristics and outcomes differ across the placenta accreta spectrum subtypes, and women with placenta increta and percreta have considerably high surgical morbidity and mortality risks. Notably, 1 in 313 women undergoing cesarean delivery had a diagnosis of placenta accreta spectrum by the end of 2017, and the incidence seems to be higher than reported in previous studies.

INTRODUCTION: This study examined national-level trends, characteristics, and perioperative outcomes of women who had intra-arterial balloon occlusion at cesarean hysterectomy for placenta accreta spectrum (PAS). MATERIAL AND METHODS: This was a population-based retrospective observational study that queried the National Inpatient Sample from October 2015 to December 2018. Study population was women who underwent hysterectomy at cesarean delivery for PAS (n = 6440 in 806 centers). Exposure allocation was the use of intra-arterial balloon occlusion. Main outcome measures were (a) characteristics associated with intra-arterial balloon occlusion use, and (b) perioperative outcome including hemorrhage, blood transfusion, coagulopathy, shock, urinary tract injury, intra-arterial balloon occlusion-related complication (arterial injury, arterial thrombosis, and lower extremities ischemia), and death, assessed in multivariable analysis. RESULTS: Intra-arterial balloon occlusion was used in 420 (6.5%) women in 64 (7.9%) centers. Utilization of intra-arterial balloon occlusion during cesarean hysterectomy for placenta accreta decreased significantly over time (from 6.3% to 3.1%, p < 0.001), but not in placenta increta (from 12.8% to 9.3%, p = 0.204) or placenta percreta (from 21.3% to 17.5%, p = 0.344). In a multivariable analysis, patient factors (younger age, earlier year, obesity, diabetes mellitus), pregnancy factors (placenta increta/percreta, previous cesarean delivery, placenta previa, and early gestational age), and facility factors (large bed capacity, urban teaching status, and Northeast/West regions) represented the independent characteristics for using the intra-arterial balloon occlusion (all, p < 0.05). In a classification-tree model, the absolute difference in intra-arterial balloon occlusion use among 18 utilization patterns was 48% (range, 0%-48%). In perioperative outcome analysis, women who received intra-arterial balloon occlusion were more likely to have coagulopathy (adjusted odds ratio [aOR] 3.43) and arterial thrombosis (aOR 9.82) in placenta accreta, but less likely to have hemorrhage (aOR 0.25) in placenta increta, and blood transfusion (aOR 0.60) and urinary tract injury (aOR 0.28) in placenta percreta compared with those who did not (all, p < 0.05). CONCLUSIONS: There is a wide range in the utilization of intra-arterial balloon occlusion at cesarean hysterectomy for PAS based on patient, pregnancy, and facility factors, which implies that there is a lack of universal practice guidelines in this surgical procedure. Whether the use of intra-arterial balloon occlusion in the severe forms of PAS improves surgical outcome merits further investigation.

BACKGROUND: In type II vasa previa, fetoscopic laser ablation has the potential to avoid prolonged hospitalization, elective prematurity, and cesarean delivery associated with traditional conservative management. OBJECTIVE: To assess the feasibility and to report perinatal outcomes of type II vasa previa patients treated via fetoscopic laser ablation. STUDY DESIGN: This is a retrospective descriptive study of all women with vasa previa treated with laser at our center between 2006 and 2019. After 2010, laser ablation of vasa previa was only offered after 31 gestational weeks. Continuous variables are expressed as means ± SD. RESULTS: 33 patients were evaluated for laser ablation of suspected vasa previa. Fifteen were not candidates (7 had type I vasa previa and 8 had no vasa previa), and the 18 remaining had type II vasa previa. Ten (56%) elected to undergo in utero laser ablation of the vasa previa vessel(s), which was successful in all patients. The mean gestational age (GA) at the time of the procedure was 28.8 ± 5.4 weeks, and the total operative time was 48.1 ± 21.3 min; there were no perioperative complications. The number of vessels lasered were distributed as follows: 1 (2 cases), 2 (5 cases), and 3 (3 cases). All patients except for 1 were subsequently managed as outpatients. The mean GA at delivery was 35.5 ± 3.2 weeks, and vaginal delivery occurred in 5 cases. The 5 patients with singletons who underwent laser ablation for primary diagnosis of type II vasa previa after the protocol change in 2010 had the following outcomes: mean GA of surgery was 32.5 ± 0.8 weeks, mean GA at delivery was 38.1 ± 1.4 weeks, vaginal delivery occurred in all cases, mean birth weight was 2,965 ± 596 g, and none were admitted to the neonatal intensive care unit. CONCLUSION: This cohort represents the largest number of vasa previa cases treated via in utero laser reported to date. Laser occlusion of type II vasa previa was technically achievable in all cases and resulted in favorable outcomes.

BACKGROUND: Congenital pleural effusion is a rare condition with an incidence of approximately one per 15,000 pregnancies. The development of secondary hydrops is a poor prognostic indicator and such cases can be managed with a thoracoamniotic shunt (TAS). Our objective is to describe postnatal outcomes in survivors after TAS placement for congenital pleural effusions. MATERIALS AND METHODS: A retrospective study of all cases with fetal pleural effusions treated between 2006 and 2016. Patients with dominant unilateral or bilateral pleural effusions complicated by secondary hydrops fetalis received TAS placement. The results are reported as median (range). RESULTS: A total of 29 patients with pleural effusion with secondary hydrops underwent TAS placement. The gestational age at the initial TAS placement was 27.6 (20.3-36.9) wk. Before delivery, hydrops resolved in 17 (58.6%) patients. The delivery gestational age was 35.7 (25.4-41.0) wk and the overall survival rate was 72.4%. Among the 21 survivors, 19 (90.5%) required admission to the neonatal intensive care unit for 15 (5-64) d. All 21 survivors had postnatal resolution of the pleural effusions. All 21 children were long-term survivors, with a median age of survivorship of 3 y 3 mo (9 mo-7 y 6 mo) at the time of last reported follow-up. CONCLUSIONS: Thoracoamniotic shunting in fetuses with a dominant pleural effusion(s) and secondary hydrops resulted in a 72% survival rate. Nearly all survivors required admission to the neonatal intensive care unit. However, a majority did not have significant long-term morbidity.

INTRODUCTION: Abundant research has reported twin-twin transfusion syndrome (TTTS) outcomes following fetal therapy. Our research describes TTTS patients who did not undergo fetal therapy. METHODS: Records from TTTS pregnancies evaluated at 16 to 26 gestational weeks were reviewed between January 2006 and March 2017. The study population comprised subjects who did not undergo fetal therapy. Based on initial consultation, patients were grouped as nonsurgical vs surgical candidates. TTTS progression and perinatal outcomes were assessed. RESULTS: Of 734 TTTS patients evaluated, 68 (9.3%) did not undergo intervention. Of these, 62% were nonsurgical candidates and 38% were surgical candidates. Nonsurgical candidates were ineligible for treatment because of fetal demise or maternal factors (placental abruption, severe membrane separation, and preterm labor). Of surgical candidates, 11 underwent expectant management, eight elected pregnancy termination, and seven planned fetal intervention but had a complication before the procedure. TTTS progression occurred in 10 (15.2%) of 66 cases. Neonatal survival in 64 cases was as follows: in 41 (64%), no survivors; in 11 (17.2%), one survivor; and in 12 (18.8%), two survivors. CONCLUSION: Nine percent of referred TTTS patients did not undergo fetal therapy, with many ineligible because of morbidity between referral and consultation. Studies of TTTS should acknowledge this subgroup and circumstances leading to lack of treatment.

OBJECTIVE: To compare outcomes between 2 umbilical cord occlusion (UCO) methods: radiofrequency ablation (RFA) versus fetoscopic-guided laser photocoagulation. METHODS: Retrospective study of all monochorionic diamniotic multiple gestations that underwent UCO with RFA (preferred after 2014) or laser (preferred before 2014). In bivariate analysis, patients treated with RFA were compared with laser. Risk factors for intrauterine fetal demise (IUFD) and 30-day survival of the co-twin were identified, and multiple logistic models were fitted to examine whether the UCO method was associated with these outcomes. RESULTS: Of 60 UCO cases, 18 (30%) underwent RFA and 42 (70%) underwent laser surgery. The RFA method was associated with co-twin IUFD after surgery (6/18 [33.3%] vs 1/42 [2.4%], P = 0.0021). In logistic regression models, patients who underwent RFA were more likely than patients who underwent laser to have an IUFD of the co-twin (OR 13.2, 1.23-142.62, P = 0.0331). These patients were also less likely to have 30-day survival of the co-twin, although this was not statistically significant (OR 0.20, 0.04-1.15, P = 0.0710). CONCLUSION: Despite clear technical advantages of RFA compared with laser, we found that RFA appeared to be associated with increased risk of post-procedure fetal demise. Further studies should be conducted to confirm these findings.

OBJECTIVE: To present outcomes of fetuses with congenital pulmonary airway malformation (CPAM) treated with sclerotherapy. METHODS: Retrospective study of 8 patients with a prenatal diagnosis of CPAM type II or III with secondary hydrops treated with percutaneous sclerotherapy using 5% ethanolamine oleate (EO). All patients underwent ultrasonic measurement of the CPAM volume ratio. Results are expressed as median (range). RESULTS: Gestational age at initial sclerotherapy was 22.0 weeks (19.6-31.4); 3 patients underwent 2 procedures. Intrauterine fetal demise (IUFD) occurred in 4 cases; 2 died on postoperative day #1 (one from inadvertent intravascular EO injection); 2 died >6 weeks after the procedure. Preoperative CPAM volume ratio was 3.6 (1.6-7.8) in survivors and 2.7 (1.7-4.7) in those with IUFD. The volume of EO at the initial sclerotherapy procedure was 3 mL (2-5) in survivors and 7 mL (6-10) in IUFD cases. The gestational age at delivery of the 4 survivors was 38.4 weeks (37.4-39.3); all underwent postnatal resection. CONCLUSION: The efficacy of percutaneous sclerotherapy for CPAM types II and III remains in question. Further studies are needed to determine the optimal dose of sclerotherapy agent and the safety and efficacy of this procedure.

The objective of this study was to describe the management and perinatal outcomes of patients with twin-twin transfusion syndrome (TTTS) and an extremely short cervical length (CL). This retrospective study examined 17 patients with TTTS and a preoperative CL ≤1.0 cm who had undergone laser surgery and perioperative cervical cerclage placement successfully. In this subset of patients, the median interval between surgery and delivery was 9.6 (range 2.1-13.9) weeks and only one patient had PPROM within 3 weeks of surgery. The median gestational age at delivery was 30.9 (range 23.1-37.6) weeks, 30-day survival of at-least-one twin was 88.2% and dual survivorship was 82.4%. Overall, patients with TTTS and a preoperative CL ≤1.0 cm who were able to undergo successful laser surgery and emergent cerclage placement had favourable outcomes. Impact statement The management of patients with twin-twin transfusion syndrome (TTTS) and extremely short cervical length (CL) varies between foetal surgery centres. This study demonstrates that laser surgery and cerclage placement in such patients are not only technically feasible, but also can result in favourable perinatal outcomes. Patients with an extremely short CL should not be uniformly excluded from laser surgery for TTTS.

INTRODUCTION: Umbilical cord occlusion (UCO) utilizing laser photocoagulation is often not considered an option for selective termination after 20 weeks of gestation due to reported limitations of the procedure because of umbilical cord size. We compared outcomes after laser umbilical cord occlusion (L-UCO) before and after 20 weeks of gestation. MATERIALS AND METHODS: We examined all patients with monochorionic- diamniotic twins and higher-order multiples (monoamniotic excluded) that underwent L-UCO at our facility between 2006 and 2014. Statistical analysis was performed using Fisher's exact and Kruskal-Wallis tests as appropriate. RESULTS: Of 43 L-UCO cases, 11 cases (25.6%) had a discordant anomaly, and 32 cases (74.4%) had twin reversed arterial perfusion (TRAP) sequence. We achieved complete vascular occlusion in 100% (43/43) of cases of attempted L-UCO. There were 22 cases (51.2%) with gestational age ≤20 weeks, and 21 cases (48.8%) with gestational age >20 weeks. Perioperative patient characteristics and outcomes did not differ between the two groups. Survival rates were 90.9% (20/22) and 100% (21/21) at ≤20 weeks of gestation and >20 weeks of gestation, respectively. DISCUSSION: The results of this study suggest that L-UCO is a reasonable surgical modality for patients prior to and beyond 20 weeks of gestation.
