Aneurysm of the Suprahepatic Inferior Vena Cava: A Case Report
DOI: 10.36660/abcimg.20250055i
Introduction
Aneurysms of the inferior vena cava (IVC) are a rare occurrence in the cardiovascular system and can present with a variety of signs and symptoms. In many cases, patients remain asymptomatic, which makes diagnosis difficult. Venous aneurysms are defined as an abnormal and persistent dilation of a vein in a specific area, with a diameter at least twice that considered normal. An IVC aneurysm is a specific type of venous aneurysm. This case report is relevant because this condition is rare; by 2021, only around 70 cases had been described in literature.
Aneurysms may arise due to fragility in the vessel wall and can be triggered by various factors, including hypertension, trauma, infection, and genetic conditions. Smoking, atherosclerosis, and chronic obstructive pulmonary disease are also considered risk factors for aneurysm development. Although they can occur in different regions of the body, they most frequently affect the cerebral arteries, the aorta, and the peripheral arteries.
