Congenital retroperitoneal vascular anomalies: impact on pelvic surgery


, : Congenital retroperitoneal vascular anomalies: impact on pelvic surgery. Archives of Gynecology and Obstetrics 284(5): 1169-1173

Congenital anomalies of the inferior vena cava (IVC) are not commonly recognized since they generally do not cause symptoms. Preoperative cross-sectional imaging can identify anomalies of vascular structures that are highly relevant to the pelvic surgeon. The clinical impact of congenital vascular variations of IVC, especially on paraaortic lymphadenectomy, is investigated. In case the surgeon is unaware of these anomalies, impending differential diagnostic confusion (paraaortic adenopathy), intraoperative blood loss and the need for transfusion may occur. The development of IVC is a complex process concerning the formation of several anastomoses between three paired embryonic veins (posterior cardinal, subcardinal, supracardinal veins). In double IVC, the left IVC typically ends at the level of the left renal vein, in an anastomosis which crosses anterior to the aorta to join the normal right IVC. Anomalies of IVC are present in 0.4-3.5% of women. As different aberrations of IVC have important clinical implications, awareness of retroperitoneal abnormal vessels is crucial to avoid diagnostic pitfalls and intraoperative complications.
