Successful surgical management of pelvic congestion and lower extremity swelling owing to absence of infrarenal inferior vena cava.

Absence of isolated infrarenal inferior vena cava (IVC) is a rare condition documented in only a few published cases and typically treated with anticoagulation. We herein describe successful surgical management of the isolated infrarenal IVC absence in a healthy 35-year-old woman who presented with disabling pelvic congestion. An ascending venogram showed the absence of infrarenal IVC with a large left ovarian vein draining pelvic collateral vessels to the normal left renal vein and suprarenal IVC. The patient was successfully treated with a common femoral vein to the suprarenal IVC bypass using a bifurcated polytetrafluoroethylene graft, with rapid symptom resolution, and remained symptom free 6 months later. This is the first reported case describing a surgical strategy for isolated infrarenal IVC absence in a symptomatic patient.
