Umbilical artery aneurysm: a case report, literature review, and management recommendations.

Background: Umbilical artery aneurysm is a rare and often lethal condition frequently associated with fetal anomalies, fetal demise, and neonatal complications.

Case: We report a case of umbilical artery aneurysm discovered at 21 weeks 2 days of gestation in a fetus of normal karyotype. Maternal hospitalization occurred at 28 weeks for antenatal testing, betamethasone administration, and monitoring for expansion of the aneurysm.

The amniotic wrinkle: a pitfall in evaluating amniotic fluid for twins.

Objective: The sonographic analysis of amniotic fluid in twin pregnancies can be complex and difficult, particularly when one twin has oligohydramnios or anhydramnios. This article describes a pitfall, the "amniotic wrinkle," which can lead to the erroneous impression that both twins have adequate fluid when one actually has little or none.

Methods: Sonograms of twin pregnancies in which the sonographer's initial assessment was of adequate fluid for each twin but imaging by the author on the same day showed one twin to have oligohydramnios were analyzed to identify recurring image patterns related to the intertwin membrane that may create this misleading impression.

Luteoma of pregnancy: sonographic findings in two cases.

Luteoma of pregnancy is a rare nonneoplastic tumor-like mass of the ovary that emerges during pregnancy and regresses spontaneously after delivery. It is usually asymptomatic and is found incidentally during a cesarean section or postpartum tubal ligation. However, luteomas can be hormonally active, with production of androgens resulting in maternal and fetal hirsutism and virilization.

Chronic abruption-oligohydramnios sequence.

Objective: To determine outcome in patients with chronic abruption.

Study Design: A retrospective review was performed of all patients delivering at a tertiary medical center during a 54-month period. All patients with a diagnosis of placental abruption with oligohydramnios or ruptured membranes were included.

Biophysical profile testing as an indicator of fetal well-being in high-order multiple gestations.

Objective: The purpose of this investigation was to determine the value of biophysical profile testing in preventing intrapartum death in patients with high-order multiple gestations (triplets or quadruplets).

Study Design: A retrospective review was performed of patients with triplets and quadruplets cared for by Phoenix Perinatal Associates from October 1988 to December 1991. Biophysical profile testing was used as the primary method of fetal surveillance in these pregnancies.

In utero fetal cardiac resuscitation: a case report.

A patient presented at 21 weeks gestation with nonimmune hydrops of her singleton fetus. A cordocentesis confirmed fetal anemia. During the course of the procedure, fetal cardiac arrest occurred.

Antepartum diagnosis of noncoiled umbilical cords.

Objective: The null hypothesis is that fetuses with noncoiled umbilical cords diagnosed in the antepartum period will have outcomes no different from those with normally coiled cords.

Study Design: We prospectively gathered data from Jan. 1 through May 18, 1992, from all fetuses undergoing routine ultrasonographic evaluation.
