title: Absence of the suprarenal segment of the inferior vena cava with a coexisting absence of the right brachiocephalic vein in a 22-year-old Caucasian male with arterial hypertension.
abstract: Congenital anomalies of the inferior vena cava (IVC) are rarely observed malformations of the venous system, occurring in 0.3% of otherwise healthy individuals, and in 0.6% to 2% of patients with coexisting cardiovascular defects. They are usually asymptomatic and recognised incidentally during imaging, operations or dissection studies. In this paper we report an extremely rare case of a 22-year-old Caucasian male, admitted for the purpose of excluding secondary causes of hypertension. During imaging of the abdomen and the thorax we found a complete lack of the suprarenal segment of the IVC, with a coexisting absence of the right brachiocephalic vein. We discuss the problem of congenital defects of the IVC and we review the relevant literature.
