Abstract

Even though the majority of abdominal aortic aneurysm s(AAAs) are asymptomatic, they can occasionally manifest as a result of adjacent structures involvement. Although the most frequent venous complication of AAA is rupture into the inferior vena cava (IVC), venous compression can infrequently occur. The authors report a particularly rare case of compression and thrombosis of the IVC by AAA. Patient was treated by preoperative placement of an IVC filter to impede pulmonary embolism and subsequently by open surgical repair. Besides discussing the circumstances associated with IVC compression by AAA, the authors also discuss the treatment strategy adopted and the possible alternatives.

Highlights

Even though the vast majority of abdominal aortic aneurysms (AAAs) are asymptomatic, they may indirectly present with symptoms related to compression of adjacent structures, such as gut, ureter, or major veins [1]

Summary

Introduction

Even though the vast majority of abdominal aortic aneurysms (AAAs) are asymptomatic, they may indirectly present with symptoms related to compression of adjacent structures, such as gut, ureter, or major veins [1]. 1. Manuscript Even though the vast majority of abdominal aortic aneurysms (AAAs) are asymptomatic, they may indirectly present with symptoms related to compression of adjacent structures, such as gut, ureter, or major veins [1]. The compression of Inferior Vena Cava (IVC) by an AAA is an extremely rare situation, needing a high level of suspicion to be diagnosed.
