Abstract
BACKGROUND: Left-sided inferior vena cava (LIVC) and duplicated inferior vena cava (DIVC) are rare asymptomatic congenital abnormalities. Unrecognized, these anomalies can be the source of major injuries and cause serious life-threatening bleeding complications especially during abdominal aortic surgery. METHODS: Retrospective data for patients with 2 major inferior vena cava (IVC) anomalies that underwent aortic surgery over a 13-year period were collected. Patient demographics, type of aortic disease and caval anomaly, surgical approach, type of aortic reconstruction associated with procedure on caval vein, postoperative complications, and in-hospital mortality were recorded. RESULTS: There were 9 patients with inferior vena cava (IVC) anomalies who underwent aortic surgery. All of them were men, with a median age of 66.2 years. Seven had an LIVC and 2 had DIVC. Five patients were operated on due to abdominal aortic aneurysm and 4 due to aortoiliac occlusive disease. In all patients, a midline transperitoneal aortic approach was performed. In 5 cases, the left IVC had to be temporarily resected and later reconstructed, and in the other 4 it was just mobilized. There were no postoperative complications except in one patient who developed deep vein thrombosis in the left calf; this was successfully treated with anticoagulant therapy. CONCLUSION: Due to favorable results and low incidence of perioperative complications and in the absence of other associated abdominal pathology, we propose the midline transperitoneal approach with mobilization or temporary resection of LIVC.
