Primary venous dissecting aneurysm arising during pregnancy: a case report and review of the literature.
This report describes a case of venous dissecting aneurysm presenting as a popliteal mass, in a 33 year old woman. A 1 x 1 x 0.5 cm lump developed early in the course of a second pregnancy. Primary venous aneurysms are rare vascular abnormalities that can affect either the superficial or deep veins, and have been described throughout the venous system. Most commonly found in the neck and central thoracic veins, they have also been found in visceral veins and extremities. There is a tendency for vascular disturbances to occur during pregnancy. The haemodynamic changes and hormonal milieu may be the cause of vascular alterations, which can lead to new aneurysm formation, or weakening of pre-existing aneurysms. This is the first reported case of a dissecting venous aneurysm, and has the added interest that it occurred during pregnancy.
