Acardiac acephalus: a case report and implications on expectant management.
Acardiac acephalus is a rare occurrence resulting from extensive anastomoses between the vessels of the monochorionic twins which invariably leads to death of the "perfused" twin and an estimated 50% perinatal mortality rate in the "pump" twin, due mainly to premature delivery or congestive heart failure. Once diagnosis has been documented, blocking the vascular flows between the twins has been the principle goal of treatment with the assumption that a more favorable chance of survival in the pump twin can be achieved. However, hasty surgical intervention without a well-designed preoperative evaluation may result in unfavorable outcomes. A 21-year-old nullipara was found to carry an acardiac parabiotic twin in a monochorionic twin pregnancy at 28 weeks of gestation and was referred to us from a local clinic. Expectant management based on the close monitoring of the well-being of the healthy co-twin is presented in this article along with review of published works on the management of this rare condition.
