Objective: To explore the treatment methods and prognosis of pregnancy-related uterine arteriovenous malformation (UAVM). Methods: A retrospective analysis was conducted on clinical data from 81 patients with UAVM treated at Peking Union Medical College Hospital between March 2019 and March 2024. Clinical manifestations, diagnostic approaches, treatment strategies and prognosis were evaluated. Results: (1) General Information: the age of patients with UAVM was (32.7±4.6) years, with median gravidity and parity of 1 (quartile range: 1, 2) and 0 (0, 1), respectively. Pregnancy termination methods included surgical abortion or curettage in 46 cases (57%, 46/81), medical induction in 17 cases (21%, 17/81), spontaneous abortion in 16 cases (20%, 16/81), vaginal delivery in 1 case (1%, 1/81), and laparoscopic pregnancy tissue removal in 1 case (1%, 1/81). (2) Clinical manifestations: clinical presentations comprised vaginal bleeding in 59 cases [73%, 59/81; median blood loss: 740 ml (440, 1 360 ml)], massive hemorrhage in 9 cases (11%, 9/81, and bleeding combined with lower abdominal pain in 8 cases (10%, 8/81). Ultrasonography revealed intrauterine masses in 65 cases [80%, 65/81; median size: 2.5 cm (1.8, 4.2 cm)]. Elevated serum human chorionic gonadotrophin-β subunit (β-hCG) levels were observed in in 55 cases [85%, 55/65; median: 62.6 U/L (14.9, 300.1 U/L)]. The median time to UAVM diagnosis via ultrasound was 30.0 days (16.0, 52.0 days) after pregnancy termination, with median peak systolic velocity (PSV) and resistance index of 59.8 cm/s (45.0, 79.6 cm/s) and 0.39 (0.36, 0.43), respectively. (3) Treatment and prognosis: treatment modalities included expectant management in 49 cases (36%, 29/81), medication in 13 cases (16%, 13/81), lesion resection in 31 cases (38%, 31/81), and uterine artery angiography in 8 cases (10%, 8/81; 5 confirmed as arteriovenous fistula). The median time of PSV returning to normal after treatment was 53.8 days (36.0, 93.4 days). The average time for β-hCG returning to normal was (60.4±20.4) days. The median return time of menses was 59.0 days (43.0, 75.4 days). Conclusions: Pregnancy-related UAVM carries a high risk of life-threatening hemorrhage, necessitating management in centers equipped for emergency uterine artery embolization. Informed consent must emphasize disease progression risks and prognosis. Treatment stratification should integrate clinical parameters and imaging features.

Objective: To investigate the incidence of port-site metastasis (PSM) after laparoscopic surgery in patients with epithelial ovarian cancer and prognostic factors influencing outcomes in those with abdominal wall PSM. Methods: Clinicopathological and follow-up data of 22 ovarian epithelial cancer patients diagnosed with abdominal wall PSM after laparoscopic surgery, who were treated in the Sichuan Cancer Hospital between May 2014 and July 2023, were retrospectively collected. A retrospective analysis of PSM characteristics and prognostic factors influencing outcomes, was conducted in these patients. Results: (1) Between May 2014 and July 2023, a total of 369 ovarian cancer patients with a history of laparoscopic surgery performed at other hospitals were admitted. Among them, 24 cases (6.5%, 24/369) were diagnosed with tumor lesions at the abdominal wall port sites via postoperative pathological examination, with a median interval time of 25.5 days (interquartile range: 19.5, 32.0 days) after laparoscopic surgery. Of these, 22 cases with complete clinicopathological and follow-up data were included in this study. (2) The age of the 22 PSM patients was (53.0±8.6) years, and the median follow-up time was 37.6 months (24.7, 63.4 months). Surgical-pathological staging revealed stage Ⅰ-Ⅱ disease in 4 cases and stage Ⅲ-Ⅳ disease in 18 cases. Histopathological differentiation included 5 cases of well-to-moderately differentiated tumors and 17 cases of poorly differentiated tumors. Pathological subtypes comprised 11 cases of high-grade serous adenocarcinoma, 5 cases of low-grade serous adenocarcinoma, and 6 cases of clear cell carcinoma or cystadenocarcinoma. Lymph node status was as follows: negative for lymph node metastasis (n=16), positive (n=5), and no lymphadenectomy performed (n=1). Postoperative residual disease was categorized as no macroscopic residual disease (n=13), residual disease ≤1 cm (n=7), and residual disease >1 cm (n=2). (3) Following secondary cytoreductive surgery combined with postoperative adjuvant therapy, the median progression-free survival and overall survival (OS) time of the patients were 8.8 months (4.6, 14.3 months) and 27.7 months (15.5, 38.4 months), respectively. Univariate Cox regression analysis demonstrated that surgical-pathological stage, histopathological differentiation grade, and lymph node metastasis status were significantly associated with OS time in patients with abdominal wall PSM (all P<0.05). In contrast, age, Eastern Cooperative Oncology Group performance status score, histopathological subtype, preoperative serum cancer antigen 125 level, presence of residual lesions after surgery and poly adenosine diphosphate ribose polymerase inhibitor usage showed no significant correlation with OS time (all P>0.05). Multivariate Cox regression analysis identified surgical-pathological stage (HR=4.579，95%CI：1.111-18.866；<

Objective: To evaluate the factors influencing test failure after resampling in non-invasive prenatal testing (NIPT) and to explore its impact on pregnancy outcomes. Methods: The information of pregnant women who failed to undergo NIPT for the first time and resampled for testing in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2018 to January 2022 were collected and retrospectively analyzed. According to the results of resampled NIPT, the pregnant women were divided into the failure group (170 cases) and the success group(485 cases), and the general clinical data and pregnancy outcomes of the two groups were compared. Results: (1) A total of 88 928 pregnant women underwent NIPT in Beijing Obstetrics and Gynecology Hospital during the study period, of which 1 299 (1.461%, 1 299/88 928) failed in the first NIPT. Among the 1 299 pregnant women who failed in the first NIPT, 720 were resampled for testing. Finally, 655 pregnant women who met the inclusion criteria and had complete clinical information and perinatal outcomes were collected. The success rate of resampling was 74.0% (485/655). Compared with the success group, the pregnant women in the failure group had a later gestational age at resampling, a higher pre-pregnancy body mass index (BMI) and a higher fetal fraction, and the differences were statistically significant (all P<0.001). (2) Among the 485 pregnant women in the success group, 130 cases (26.8%, 130/485) were detected with chromosome aneuploidy. Among the 170 pregnant women in the failure group, 8 cases had abnormal amniocentesis, 2 cases had abnormal maternal serum screening of aneuploidy in the second trimester, 3 cases had abnormal ultrasound anomaly removal, and 157 cases had no abnormality. (3) The incidence of fetal or neonatal malformation in the failure group was significantly higher than that in the success group [11.2% (19/170) vs 5.8% (28/485), P=0.019], but after adjusting for age and pre-pregnancy BMI, fetal or neonatal malformation was not associated with the success of resampling (RR=0.675, 95%CI: 0.346-1.319; P=0.250). The incidences of gestational diabetes mellitus and hypertensive disorders in pregnancy in the failure group were significantly higher than those in the success group (all P<0.05), but after adjusting for age and pre-pregnancy BMI, only the incidence of gestational diabetes mellitus in the failure group was higher (RR=0.630, 95%CI: 0.426-0.932; P=0.021). Conclusions: For pregnant women who failed the initial NIPT, the success of the resampling test is associated with pre-pregnancy BMI and the gestational week at the time of resampling. Those who failed the resampling test are more likely to develop gestational diabetes mellitus. When providing genetic counseling for pregnant women who failed the initial NIPT, it is important to consider the successful rate of resampling

Objective: To investigate the risk factors for severe postpartum hemorrhage (SPPH) during vaginal delivery of twin pregnancy. Methods: A retrospective analysis was conducted on clinical data from twin pregnancies ≥28 weeks' gestation undergoing vaginal delivery at Peking University Third Hospital between January 2016 and December 2023. The twin pregnant women were divided into the SPPH group (postpartum hemorrhage ≥1 000 ml within 24 hours) with 22 cases and the non-SPPH group with 171 cases. The differences between the two groups were compared and the risk factors for SPPH were analyzed. Results: (1) The incidence of SPPH during vaginal delivery in twin pregnancies was 11.4% (22/193). The causes of SPPH included 12 cases (54.5%, 12/22) of simple uterine atony, 4 cases (18.2%, 4/22) of uterine atony combined with vaginal lacerations after forceps delivery, and 6 cases (27.3%, 6/22) of uterine atony combined with placental factors. (2) The age and postpartum hospital stay in the SPPH group were significantly higher than those in the non-SPPH group (all P<0.05). Compared to the non-SPPH group, the proportion of hypertensive disorders in pregnancy, accreta placenta implantation, and anemia in the SPPH group were significantly increased, and the birth weight of newborn 1st, the sum of the birth weights of two newborns, the duration of the second stage of labor, and the proportion of labor followed induction were also significantly increased (all P<0.05). (3) Multivariate analysis showed that age ≥38 years (OR=16.785, 95%CI: 2.679-105.166; P=0.003), the second stage of labor ≥90 minutes (OR=9.670, 95%CI: 2.532-36.930; P=0.001), hypertensive disorders in pregnancy (OR=5.945, 95%CI: 1.702-20.761; P=0.005), and anemia (OR=8.048, 95%CI: 2.086-31.049; P=0.002) were independent risk factors for SPPH in twin pregnancies during vaginal delivery. Conclusions: Anemia should be actively corrected during twin pregnancy. For twin pregnant women with advanced age, hypertensive disorders in pregnancy, or other risk factors of SPPH, if vaginal delivery is chosen, attention should be paid to the management of labor duration, dynamic assessment of the risk of postpartum hemorrhage, and proactive measures should be taken to ensure a smooth vaginal delivery and effectively reduce the incidence of SPPH.

Objective: To investigate the clinical characteristics of pregnancy complicated with Behçet's disease, so as to improve the diagnosis and treatment of the disease and improve maternal and neonatal outcomes. Methods: A retrospective analysis was conducted on the clinical data of 10 pregnant women with Behçet's disease, who were admitted to Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2016 to June 2024. The maternal and neonatal outcomes were analyzed. Results: The 10 pregnant women with Behçet's disease had a mean age of (31.2±5.3) years (range: 25-41 years). Nine were diagnosed before pregnancy and one was diagnosed during the second trimester of pregnancy. The mean age of disease onset was (20.5±6.1) years (range: 10-34 years). Clinical manifestations included oral ulcers, genital ulcers, fever, uveitis, hematochezia, diarrhea, constipation, and skin rash. Nine of them received medication during pregnancy, while one did not. The disease conditions of five women were active during pregnancy and other five remained stable. In terms of delivery mode, five women had vaginal delivery and five delivered by cesarean section. Nine delivered at term and one had preterm delivery. All neonates survived without adverse outcomes. Conclusions: The management of pregnancy complicated with Behçet's disease requires a multidisciplinary team approcach. Individualized decisions regarding medication, timing of delivery, and mode of delivery are essential to achieve optimal maternal and fetal outcomes.
