Obturator artery is frequently a branch of anterior division of the internal iliac artery. It has drawn attention of pelvic surgeons, anatomists and radiologists because of the high frequency of variations in its course and origin. The obturator vein is usually described as a tributary of the internal iliac vein. During routine dissection classes to undergraduate medical students we have observed obturator artery arising from external iliac artery, obturator vein draining into external iliac vein, communicating vein between obturator vein and external iliac vein and inferior epigastric artery arising from the obturator artery. The anomalous obturator vessels and inferior epigastric artery in the present case may be in a dangerous situation in pelvic surgeries that require dissection or suturing along the pelvic rim. Developmental reasons and clinical significances of the variations are discussed.

The occurrence of an aberrant obturator artery is common in human anatomy. Detailed knowledge of this anatomical variation is important for the outcome of pelvic and groin surgeries requiring appropriate ligation. Familiarity with the occurrence of an aberrant obturator artery is equally important for instructors teaching pelvic anatomy to students. Case studies highlighting this vascular variation provide anatomical instructors and surgeons with accurate information on how to identify such variants and their prevalence. Seven out of eighteen individuals studied (38.9%) exhibited an aberrant obturator artery, with two of those individuals presenting with bilateral aberrant obturator arteries (11.1%). Six of these individuals had an aberrant obturator artery that originated from the deep inferior epigastric artery (33.3%). One individual had an aberrant obturator artery that originated directly from the external iliac artery (5.6%).

Abstract The obturator artery is a branch of the internal iliac artery, although there are reports documenting variations, with origin from neighboring vessels such as the common iliac and external iliac arteries or from any branch of the internal iliac artery. It normally runs anteroinferiorly along the lateral wall of the pelvis to the upper part of the obturator foramen where it exits the pelvis by passing through said foramen. Along its course, the artery is accompanied by the obturator nerve and one obturator vein. It supplies the muscles of the medial compartment of the thigh and anastomoses with branches of the femoral artery on the hip joint. We report a rare arterial variation in a Brazilian cadaver in which the obturator artery arose from the external iliac artery, passing beyond the external iliac vein toward the obturator foramen, and was accompanied by two obturator veins with distinct paths. We also discuss its clinical significance.

AbstractMost commonly, the Obturator artery arises from the anterior trunk of internal iliac artery. However, origin of the Obturator artery from external iliac artery was reported at 25% by Missankov et al. [3], 1.1% by Bergman et al. [1], 1.3% by Jakubowicz and Czerniawska- Grzesinska [2].Due to its high frequency of variations in course and origin, Obturator artery had drawn the attention of anatomists, surgeons and radiologists. In this case report, we are presenting an anomalous origin of right Obturator artery from right external iliac artery. The knowledge of this variation is important anatomically, radiologically and surgically.

Purpose: To describe the anatomical variations of the corona mortis, a vascular anomaly that may lead to dangerous hemorrhage and possible death. Case Report: A 46-year-old male cyclist was involved in a collision with a car, during which he sustained fractures to the left ribs and pelvic ring. Abdominal ultrasound imaging demonstrated a large (12×6×7 cm) nonhomogeneous mass ventral to the bladder, suggestive of a hematoma, which was confirmed on computed tomography. During angiography, 2 branches of the internal iliac artery were identified as sources of the bleeding; these were successfully embolized with microcoils, but the bleeding continued. Examination of the external iliac system found a lacerated aberrant obturator artery arising from the inferior epigastric branch of the external iliac artery, a condition known as the corona mortis. Additional embolization quelled the hemorrhage. Conclusions: Coil embolization of the internal iliac artery branches is very effective in managing hemorrhage due to pelvic fractures, but variations in the origin of the obturator artery from the internal or external iliac artery may be additional sources of bleeding.

Transcatheter angiography and embolization has long been recognized as the gold standard for patients with hemodynamic instability secondary to blunt pelvic trauma. While often the bleeding source can be readily localized based on the distribution of extravasation on preprocedural Computed Tomographic Angiography, one should be cautious in assessment for aberrant anatomy. A variant obturator artery originating from the inferior epigastric branch of the external iliac artery is commonly referred to as the corona mortis. We present a case of blunt pelvic trauma in which a patient demonstrated extravasation in the anterior distributions of both internal iliac arteries. Following embolization of bilateral internal iliac arteries, identification and embolization of bilateral corona mortis branches was crucial to achieving hemodynamic stability in this patient.
