A Huge Umbilical Vein Aneurysm: Case Report and a Brief Review of Literatures Describing Umbilical Vessel Aneurysm

Abstract
An umbilical vein aneurysm is rare, but appears to be associated with fetal morbidity and mortality. There are no specific guidelines for a pregnancy with umbilical vein aneurysm and the management is substantially up to the clinician. We report a case of intra-amniotic umbilical vein aneurysm prenatally diagnosed by ultrasound at 35 gestational weeks. Because the aneurysm was growing rapidly, prompt cesarean delivery was conducted. After delivery, a huge fusiform umbilical cord was noted, which was confirmed to be umbilical vein aneurysm by pathological examination. We also reviewed previous reported cases and summarized the management in prenatally detected umbilical vein aneurysms. Additionally, this case report is about one of the umbilical vein aneurysms with the largest size ever reported.
