Achsenanomalien der Vena cava inferior mit paracavalem venösen Aneurysma und renalem Kollateralkreislauf

Anomaly of the vena cava inferior with paracaval venous aneurysm and renal collateralisation Aneurysms of the great venous vessels represent anatomical rarities. Most malformations of the venous system published so far concern mainly the inferior vena cava and arise in different formations. Reports of malformations of the renal veins are limited to a few case reports and may lead to diagnostic and therapeutic difficulties. We report on an case of a asymptomatic, aneurysmatic venous malformation of the vena cava inferior With consideration of the entire findings we preferred a conservative treatment of the patient.
