Morphological and morphometrical characteristics of arterial, venous and accessory venous Corona Mortis: Case Report

Abstract

Corona Mortis (CM) is a variation determined by the arterial and / or venous connection between the anastomotic branches of the obturator artery and the inferior epigastric branch on the superior branch of the pubis. Knowledge about the different morphological and topographic possibilities of MC is relevant and deserves attention because it is an anatomical structure with high potential for lethal risk during pelvic surgical procedures. Thus, the study sought to characterize the CM vessels found in a right hemipelve during a routine dissection. Measurements of length, diameter and distances were measured with a digital caliper. The arterial CM was 4.8 cm long and 0.2 cm in diameter, while the venous CM had 4.1 cm and 0.31 cm, respectively. The presence of an accessory vein (VCMa) was also found. Therefore, the knowledge about such variation is fundamental to minimize the risks of bleeding and possible iatrogenic errors in this region.
