“… 15 Furthermore, gynecologic and urologic surgeries, extraperitoneal inguinal hernioplasty, laparoscopic herniorrhaphy, Burch procedures, arterial embolization, periacetabular osteotomies, traumas, and resection of tumors require extensive knowledge of the pelvic vascular anatomy because of the risks of bleeding and damage to other structures, such as the ON, and since the pelvic wall vessels are often obscured by preperitoneal tissue, fat, and lymphatics, it is critical that surgeons anticipate these variations. 5 - 9 , 16 …”

Rare origin of the obturator artery from the external iliac artery with two obturator veins

et al. 2016

View full text Add to dashboard Cite

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.

“…It is also crucial to study these vessels in view of the many reports in the literature describing pelvic fractures associated with hemorrhage and iatrogenic lesions, with special regard to the “corona mortis” arterial variation. 1 , 2 , 4 - 9 …”

“…9 According to a study conducted by Rajive et al, this anomaly was observed in 2% out of 50 cadavers. 15 However, in the same case reported by Deshmukh et al, the left obturator vein crossed the pelvic brim and drained into the external iliac vein. 9 This variation has important implications during open and laparoscopic surgeries involving the pelvis, such as hernia repairs and gluteal muscle grafts in females undergoing breast augmentation.…”

“…Understanding the possible OA origin variations is important while performing pelvic and groin surgeries requiring appropriate ligation. In instances of acute pelvic or groin trauma, such varying origins may be a significant source of persistent hemorrhages that are difficult to manage [ 10 , 11 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Thus, OA origin variations are an important anatomical topic for a range of medical fields as varied as gynecology, orthopedics, and urology [ 25 , 26 ].…”

Frequency and Clinical Review of the Aberrant Obturator Artery: A Cadaveric Study

2020

View full text Add to dashboard Cite

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%).
