Double inferior vena cava in retroperitoneal surgery for testicular cancer

Abstract

Double inferior vena cava is a rare congenital malformation that represents 0.7% of the population. A clinical case of a 32-year-old man with a diagnosis of a testicular tumor is presented. After extension studies with tomography scans, a 2.5 x 2 cm retroperitoneal mass at the left inter cavus-aortic level and the presence of a double inferior vena cava were evidenced. Recognizing this anatomical variant represents part of the preoperative evaluation since non-identification could lead to surgical complications.
