The space of Bogros and the deep inguinal venous circulation.

The ideal reconstruction of the floor of the inguinal canal during a herniorrhaphy implies a good anatomic dissection and exposure. This cannot be accomplished without entering the subinguinal space of Bogros. This space presents a venous circulation that has not been entirely identified in the past. As an aid to accomplishing a safe and bloodless dissection, these vessels have been described--the deep inferior epigastric vein, the iliopubic vein, the rectusial vein, the retropubic vein and the communicating rectusio-epigastric vein, and their relationship into a venous circle. The need to map these vessels is becoming more crucial as surgeons choose varied approaches to the space of Bogros and insert synthetic mesh that requires anchoring.
