Angiographic arterial embolization and computed tomography-directed drainage for the management of hemorrhage and infection with abdominal pregnancy.

Hemorrhage during or after surgery, pelvic abscess, bowel obstruction, and prolonged febrile morbidity can complicate the puerperal course of the gravida after removal of an extrauterine fetus with nondisturbance of the extrauterine placenta. In this report we describe the successful angiographic arterial gelfoam embolization of the placental vascular bed to control heavy postoperative hemorrhage in a mother suffering adult respiratory distress syndrome after removal of the fetal portion of her abdominal pregnancy. Six weeks later, computed tomography (CT)-directed drainage by catheter of a placental abscess was performed. Selective angiographic transcatheter embolization with gelfoam is a useful tool for the control of hemorrhage in the gravida who is an unfavorable operative candidate or who may present technical hemostasis problems peculiar to the placenta with abdominal pregnancy. Later use of CT-directed catheter drainage of the infected residual placental mass provided a nonoperative means of treatment.

Pharmacologic agents in stroke prevention, acute stroke therapy, and interventional procedures.

Pharmaceutical agents have moved far beyond just the aspirin and heparin that were the mainstays of stroke and interventional therapy as recently as 10 to 15 years ago. Our understanding of the mechanisms of thrombus formation and vascular response to damage as well as our armamentarium has tremendously improved in the past decade. Direct thrombin inhibitors, powerful antiplatelet agents, new fibrinolytic agents, and statins now allow far greater manipulation of the intraprocedural and postprocedural clot cascade and atherogenesis. It is mandatory that current-day interventionists understand the correct and appropriate use of these agents to achieve the desired outcomes of therapy.
