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.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
