Massive atonic bleeding during cesarean delivery in a patient with chronic idiopathic intestinal pseudo-obstruction: A case report and literature review.

A 35-year-old primigravid woman with chronic idiopathic intestinal pseudo-obstruction presented to our institution. Except for an enlarged fetal bladder, her pregnancy was almost uneventful until she developed pre-eclampsia requiring emergent cesarean section at 34 weeks gestation. After delivery, intractable uterine atony developed with blood loss reaching 3500 mL within 15 min. Following a B-Lynch suture, the bleeding attenuated but uterine atony persisted; lochia persisted for 3 months post-partum. The infant was diagnosed with megacystis microcolon intestinal hypoperistalsis syndrome after birth. The mother's clinical course and previous reports suggested that atonic bleeding was associated with the pathology of chronic idiopathic intestinal pseudo-obstruction; the infant's disease was considered to be maternal-related disease. Clinicians should be vigilant in pregnant patients with chronic idiopathic intestinal pseudo-obstruction especially with these complications.

Pregnancy managed by unfractionated heparin after mechanical aortic valve replacement.

Pregnancy after mechanical valve replacement involves high risk. Maternal valve thrombosis and hemorrhagic complications are associated with lethal outcomes; therefore, strict anticoagulant therapy is needed. Our patient was 26-year-old primiparous woman. She had undergone aortic valve replacement with a mechanical valve at 4 years of age and had used warfarin 3 mg per day since then. Because of her desire for a baby, she stopped warfarin and conceived spontaneously. She was referred to our hospital. After being informed of her choices, unfractionated heparin (UFH) administration was started. She experienced mild heart failure with sacroiliitis, bacteremia, and hematuria during pregnancy. She delivered her newborn at 37 weeks. Blood loss at delivery was 220 g. Administration of UFH was restarted 4 h after delivery and 3 mg of warfarin was administered from postpartum day (PPD) 6. Hemostatic suturing was required for vaginal bleeding on PPD7. A therapeutic dose of warfarin was achieved on PPD9. Although warfarin use is recommended as anticoagulant therapy for pregnant woman with mechanical valves, the safety and efficacy of UFH have not yet been clarified because of its limited use. More cases are needed to clarify this.

Prolongation of Second Twin's Delivery Until Term: A Rare Case of Delayed-Interval Delivery.

Although some cases describing delayed birth of the second twin have been published recently, delay of delivery beyond 36 weeks seems scarce. We report a case of delayed-interval delivery wherein prolongation of the second twin's delivery until term with a subsequent favorable infantile outcome. In this case, the stillbirth of the first twin occurred at 25 weeks' gestation. Prophylactic tocolysis was performed with ritodrine and magnesium sulfate, and a McDonald cerclage was performed 2 days after delivery of the first twin. Ampicillin and gentamicin were also administered for the purpose of prevention of intrauterine infection. No clinical sign of chorioamnionitis was found thereafter, and full term uneventful delivery was achieved. With this experience, we believe that delayed-interval delivery can be effective in prolonging gestation and should be an option if the first twin developed an extreme preterm delivery.
