Abstract The internal iliac artery (IIA) is one of the branches of the common iliac artery and supplies the pelvic viscera, the musculoskeletal part of the pelvis, the gluteal region, the medial thigh region and the perineum. During routine cadaveric dissection of a male cadaver for undergraduate Medical students, we observed variation in the course and branching pattern of the left IIA. The artery gave rise to two common trunks and then to the middle rectal artery, inferior vesicle artery and superior vesicle artery. The first, slightly larger, common trunk gave rise to an unnamed artery, the lateral sacral artery and the superior gluteal artery. The second, smaller, common trunk entered the gluteal region through the greater sciatic foramen, below the piriformis muscle and presented a stellate branching pattern deep to the gluteus maximus muscle. Two of the arteries forming the stellate pattern were the internal pudendal artery and the inferior gluteal artery. The other two were muscular branches.

Variaciones en el patrón de ramificación de la arteria ilíaca interna son ocasionalmente encontradas en las disecciones cadavéricas y las cirugías. Algunas de las variaciones son de importancia quirúrgica y clínica e ignorarlas podría derivar en alarmantes sangrados durante las prácticas quirúrgicas. Evaluamos las variantes en el patrón de la arteria ilíaca interna en un cadáver masculino. La división de la arteria ilíaca interna dio origen a las arterias rectal media y obturatriz. La arteria vesical superior tenía su origen en la arteria obturatriz. La división posterior de la arteria ilíaca interna dio lugar a las arterias iliolumbar, sacra lateral, glútea superior y pudenda interna. La arteria glútea inferior estaba ausente. Variations in the branching pattern of the internal iliac artery are occasionally encountered during cadaveric dissections and surgeries. Some of the variations are of surgical and clinical importance and ignoring them might result in alarming bleeding during surgical procedures. We report variant branching pattern of the right internal iliac artery in a male cadaveric specimen. The anterior division of the internal iliac artery gave origin to obturator and middle rectal arteries. Superior vesical artery took its origin from the obturator artery. The posterior division of the internal iliac artery gave iliolumbar, lateral sacral, superior gluteal and internal pudendal arteries. The inferior gluteal artery was absent.

Internal iliac artery (IIA) is one of the terminal branches of the common iliac artery and is the prime artery of pelvis. The artery has many parietal and visceral branches and hence the variations are frequently noted. The larger branches, namely, the inferior gluteal artery, the superior gluteal artery, and the internal pudendal artery, show sufficient regularity in their patterns of origin to allow typing. The variability of the IIA and its branching pattern were studied by dissecting sixty-eight male pelvic halves (34 right and 34 left) and forty-eight female pelvic halves (24 right and 24 left sides). In significant number of specimens, IIA terminated without dividing into 2 trunks as against the usual description. There was also considerable interchange of branches between the 2 terminal divisions. The patterns of branching noted were grouped as per Adachi’s classification. The incidence was noted to be as follows: type Ia in 60.6%, type Ib in 2.6%, type IIa in 15.8%, and type III in 21%. The other types were not observed in this study. Conclusion. Interventions in the pelvic region must take into account the variability of the IIA and its branches that can modify the expected relations and may lead to undesired hemorrhagic or embolic accidents.

Objetivo: Estudiar el patrón de ramificación de la arteria ilíaca interna del feto y que son equivalentes a la disposición de las ramas ilíacas internas en los adultos. Métodos: Veinticuatro mitades de pelvis fueron utilizados como muestras. Que se obtuvieron de fetos nacidos muertos, de 5 a 9 meses de edad gestacional. Resultados: la arteria ilíaca interna está en consonancia con la arteria ilíaca común y más grande que la arteria ilíaca externa. Tres tipos de ramificación se observaron sobre la base de las grandes ramas, a saber, la arteria glútea inferior, la arteria pudenda interna y la arteria glútea superior. Los resultados se correlacionaron con los patrones de ramificación descriptos por Piersol (1930). Conclusión: La disposición más común, tenía dos grandes troncos procedentes de la arteria iliaca interna, la posterior era la arteria glútea superior y la anterior se dividía en arterias pudenda y glútea inferior. Los otros patrones conducen variables en los adultos que son de importancia embriológicos y quirúrgicos. Objective: To study the branching pattern of fetal internal iliac artery and to correlate with the arrangement of the internal iliac branches in adults. Methods: Twenty four pelvic halves were used as specimens. They were obtained from the dead born fetuses of 5 to 9 months of gestational age. Results: Internal iliac artery was in line with the common iliac artery and larger than the external iliac artery.  Three types of branching were observed based on the large branches namely inferior gluteal artery, internal pudendal artery and superior gluteal artery. The findings were correlated with the patterns of branching described by Piersol (1930). Conclusion: The most common arrangement had two large trunks originating from internal iliac artery, the posterior one being superior gluteal artery and the anterior one divided into internal pudendal and inferior gluteal arteries. The other patterns lead to variable branching patterns in adults that are of embryological and surgical significance.

Abstract Background And Aims: Variations in the origin of the parietal branches of internal iliac artery are of great surgical and radiological importance. Very few studies regarding the variations in the origin of the branches of internal iliac artery have been reported from South India. The present study was carried out to investigate the sites of origin of the large parietal branches of the internal iliac artery in a sample Indian population from two Southern states. Materials And Methods: 50 pelvic halves of embalmed cadavers were dissected and observed for variations in the origins of superior gluteal, inferior gluteal, internal pudenda! and obturator arteries. Results: Among the 50 pelvic halves studied, the origins of superior gluteal, inferior gluteal and internal pudenda! arteries confirmed to a Type I arrangement on the Adachi scale in 30 cases (60%), a Type III pattern being found in 15 cases (30%) and a Type II pattern was seen in 4 cases (8%). Type IV was less frequent and was seen in only one case (2%). The obturator artery arose directly from the anterior division of internal iliac artery in 40% of cases; in the rest of specimens, it arose as a branch from either the inferior gluteal-internal pudenda! trunk or internal pudenda! or superior gluteal or iliolumbar arteries. Conclusions: The data obtained from this study show that the branching pattern of internal iliac artery is subject to great variation, especially with regard to its four large parietal branches. These observations are important in diagnostic & interventional radiological procedures of this major artery as well as in pelvic surgery to minimize intra-operative blood loss.

Introduction: In patients with severe pelvic ring injuries, exsanguination still is the leading cause of death in the early post-injury phase. While mechanical pelvic ring stabilization and pre-peritoneal pelvic packing are mainly addressing venous bleeding, angio-embolization aims to control arterial bleeding. The goal of the present study was to evaluate the rate of postoperative angio-embolization after mechanical pelvic ring injury stabilization and pre-peritoneal pelvic packing. Bleeding sources detected in the angiography and the patient's outcome were investigated.Patients and Methods: Retrospective observational cohort study at a single academic level I trauma center, reviewing all patients with pelvic ring injuries admitted from 01/2010 to 12/2019. Patients with emergent mechanical pelvic ring stabilization (supraacetabular external fixator and/or pelvic C-clamp) and direct pre-peritoneal pelvic packing were further analyzed. Patients that underwent postoperative angio-embolization were compared with those that did not. All postoperative angio-embolizations were evaluated with regards to bleeding sources and type of embolization.Results: During the study period, a total of 39 patients required immediate mechanical pelvic stabilization and direct pre-peritoneal pelvic packing. Of these, 12 patients (30.8%) underwent a postoperative angio-embolization. The following vessels were identified as bleeding sources: superior gluteal artery (n = 6), obturator artery (n = 2), internal pudendal artery (n = 2), unnamed branches of the internal iliac artery (n = 3). A selective embolization was successful in 11 patients; in 1 patient, an unilateral complete occlusion of the internal iliac artery was performed to control the bleeding. Mean time from hospital admission to the surgical procedure was 52.8 ± 14.7 min and the mean time from admission to angio-embolization was 189.1 ± 55.5 min. The in-hospital mortality rate of patients with angio-embolization was 25.0% (n = 3). Of these, 2 patients died due to multiple organ failure and 1 patient due to severe head injury.Conclusion: Secondary angio-embolization after external pelvic fixation and pre-peritoneal pelvic packing was effective in controlling ongoing bleeding. The most frequently detected bleeding vessel was the superior gluteal artery, which is difficult to surgically address, further highlighting the importance of angio-embolization in the management algorithm.

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.
