Corona mortis in the setting of pelvic trauma: Case series and review of the literature

Abstract

Corona mortis is a variant vessel located posteriorly against the superior pubic ramus, “crowning” the pelvis; actual prevalence is unknown due to broad definitions: A connection between the obturator artery and an external iliac artery branch or the external iliac artery anastomosis, or any variant vessel behind the superior pubic ramus. Rapid identification and immediate treatment of injury to an arterial corona mortis resulting from pelvic trauma or pelvic surgeries are essential as hemorrhage or death may result. Interventional radiology can selectively target corona mortis and obstruct hemorrhage through catheter-guided embolization. We present four cases of corona mortis and pelvic trauma with successful embolization and include a comprehensive literature review to further educate regarding the morbidity and potential mortality associated with this important anatomic variant.

Corona mortis injury during anterior vaginal wall suspension: A case report

“…The prolonged time to bleeding witnessed is consistent with previous reports of corona mortis injury with pelvic fractures resulting in delays in hemorrhage and hemodynamic compromise. [ 7 ] This is thought to be secondary to vasospasm of the injured vessel. Fortunately, this patient was still being monitored in the PACU when the bleeding ensued, which allowed for a prompt evaluation, resuscitation, and ultimately embolization.…”

“…[ 6 ] Injury to this vessel can lead to rapid hemorrhage, as it is supplied by two high-pressure systems. [ 7 ]…”
