Cost-benefit analysis of autologous blood donation in obstetrics.
To determine whether there are predictors of peripartum transfusion, other than placenta previa, that identify a population of pregnant women whose risk of transfusion is high enough to justify antepartum autologous blood donation. ⋯ In obstetric patients without placenta previa, the need for peripartum red-cell transfusion cannot be predicted with sufficient accuracy to justify the costs of antepartum autologous blood donation.

Case ReportsAntepartum diagnosis of placenta previa percreta by magnetic resonance imaging.
Placenta previa percreta is a rare but highly morbid condition usually diagnosed intraoperatively. Placental manipulation results in severe bleeding. Magnetic resonance imaging (MRI) might allow antepartum diagnosis of this condition. ⋯ Antepartum diagnosis of placenta previa percreta by MRI altered the usual diagnostic and surgical approach, diminishing blood loss and morbidity.

Case ReportsHypoplastic pulmonary artery: an unusual entity mimicking pulmonary embolism during pregnancy.
Hypoplastic pulmonary artery is an unusual congenital malformation. We describe a case of hypoplastic pulmonary artery diagnosed during the third trimester of pregnancy. The clinical and radiologic features mimicked pulmonary embolism, including hemoptysis, chest pain, pleural effusion, mild hypoxemia, and a suggestive ventilation-perfusion scan. Accurate differentiation of this entity from pulmonary embolism is necessary to obviate the need for prolonged anticoagulation.

Case ReportsTermination of supraventricular tachycardia with intravenous adenosine in a pregnant woman with Wolff-Parkinson-White syndrome.
Pregnancy is associated with an increased frequency of arrhythmias in women with Wolff-Parkinson-White syndrome. We describe the use of intravenous (IV) adenosine for the acute termination of a narrow complex tachycardia in a pregnant patient with this syndrome. ⋯ Adenosine is effective in rapidly terminating maternal narrow complex tachyarrhythmias before and during delivery in women with Wolff-Parkinson-White syndrome. It can also treat fetal bradycardia resulting from the maternal arrhythmia.

Case ReportsRitodrine therapy in the presence of chronic abruptio placentae.
Betamimetic therapy is usually contraindicated for the treatment of premature labor associated with abruptio placentae. We report prolongation of a pregnancy for 7 weeks using ritodrine despite the presence of placental abruption. ⋯ Although clinical suspicion of abruptio placentae remains a contraindication to betamimetic therapy, exceptions may be made if fetal and maternal well-being can be monitored and if a fully staffed operating room is always available for immediate cesarean delivery. The benefits of this management may outweigh the associated risks for carefully chosen, very preterm gestations.
