Endovascular reconstruction of the inferior vena cava in a patient presenting with deep venous thrombosis with concomitant inferior vena cava hypoplasia and aneurysmal dilatation of the iliac veins

Congenital malformations of the inferior vena cava are rare and remain an under recognised cause of spontaneous deep venous thrombosis (DVT). The purpose of this case report is to highlight the rare occurrence of a concomitant iliac vein aneurysm and the feasibility of endovascular reconstruction in the presence of extensive iliocaval thrombus burden, especially in cases where other treatment modalities have been unsuccessful.
