Bilateral variation of the venous corona mortis with a presentation previously undescribed

Abstract

The corona mortis is an anatomic variant that involves anastomosis between obturator vessels, external iliac vessels and/or inferior epigastric vessels. It is clinically and surgically important because its section may lead to fatal consequences when pelvic procedures are performed. We report a case in which, during an anatomical dissection in a female cadaver, a bilateral corona mortis that involved obturator vessels and external iliac vessels was found, presenting differences on each side, an undescribed type of corona mortis was found and a classification modification was proposed.
