摘要
the agenesis of the inferior vena cava is a rare congenital anomaly, which was recently identified as an important risk factor for the development and recurrence of deep venous thrombosis especially in young people. the goal of this work was to report the case of a patient who presented deep venous thrombosis approximately two months after varicose vein surgery. the computerized angiotomography demonstrated the presence of a complex venous anomaly with absence of the inferior vena cava.
