  ABSTRACT: Uterine artery pseudoaneurysm can occur after cesarean section or traumatic delivery, usually manifesting as postpartum hemorrhage. Pregnant women after adenomyomectomy sometimes suffer some adverse events, among which uterine rupture has been widely acknowledged. We describe a post-abortive woman who had uterine artery pseudoaneurysm occupying the entire uterine cavity. She underwent adenomyomectomy and became pregnant. She experienced a missed abortion and underwent evacuation and curettage, which caused bleeding. Several days later, ultrasound revealed an intrauterine mass with marked blood flow. Angiography revealed the un-ruptured left uterine artery pseudoaneurysm, with arterial embolization stopping the flow within the pseudoaneurysm. Adenomyomectomy with subsequent curettage was considered to have caused the pseudoaneurysm. We must be cautious that pseudoaneurysm may occur in post-abortive women after adenomyomectomy.

  ABSTRACT: Since the introduction of B-Lynch suture (1), various uterine compression sutures have been devised to achieve hemostasis during postpartum hemorrhage caused by atonic bleeding (2). Uterine compression sutures have also been used for bleeding after cesarean section for placenta previa or placenta previa accreta (1-4). We devised a novel uterine compression suture, the Matsubara-Yano (MY) suture, and have summarized various such sutures in this journal (2). © 2013 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2013 NordicFederation of Societies of Obstetrics and Gynecology.

  ABSTRACT: AIM: Assisted reproductive technology (ART) has increased the incidences of multiple gestations and low birth weights, which frequently warrant pediatric surgery. ART may have also increased the rate of birth defects. In this study, we aimed to determine whether infants conceived after ART required neonatal surgery more frequently compared with naturally conceived infants. MATERIAL AND METHODS: Our study population comprised 1891 infants (160 ART (+) and 1731 ART (-)) who were admitted to our neonatal intensive care unit during a 5-year period (January 2006-December 2010); of these, 198 infants (9 ART (+) and 189 ART (-)), with diseases requiring surgery, were referred to pediatric surgeons (consultation cases). We examined the following: (i) factors potentially increasing the requirement for surgery; (ii) frequency of birth defects; and (iii) maternal factors that may increase the need for surgery. RESULTS: A significantly higher incidence of multiple gestation and low birth weight was observed in the ART (+) group than the ART (-) group. However, ART did not yield a higher rate of surgery and birth defects: overall, the rate of surgery was 4% (7/160) in the ART (+) group and 8% (143/1731) in the ART (-) group. Of 198 consultation cases, the percentage of infants actually requiring surgery was approximately the same in the ART (+) group (7/9 [78%]) and the ART (-) group (143/189 [76%]). CONCLUSION: Infants conceived after ART comprised a small proportion of neonatal surgery cases, and did not require surgery more frequently.
