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 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.

ABSTRACT Aim To describe two different approaches of performing internal iliac artery ligation and their usefulness in different clinical situations. Introduction Internal iliac artery ligation is a very useful method to control pelvic hemorrhage. It can become a necessity at any point of time while performing obstetric or gynecological surgeries, and it is a procedure that needs to be accomplished in a matter of few minutes, before the patient goes into irreversible shock. Techniques Internal iliac artery ligation can be done by approaching the artery by opening the retroperitoneal space, either by dividing the round ligament or by opening the pouch of Douglas. The internal iliac artery is identified by locating the bifurcation of the common iliac artery with the ureter crossing it. The external iliac artery is the lateral branch of the common iliac artery and it runs a straight course to continue as the femoral artery in the lower limb. The ureter is identified by peristalsis, and the internal iliac artery is the short medial branch of the common iliac which runs a short course and immediately divides into an anterior and a posterior division, which in turn divide into a number of branches. The uterine artery is the branch of anterior division of the internal iliac artery. The internal iliac artery is ligated by passing a stout suture material under it with the help of a right-angled forceps, or it can be directly occluded with clips, applied using a clip applicator. Conclusion Both the approaches are equally effective and easy to perform. Approaching the internal iliac artery through the round ligament is easier in gynecological surgeries, whereas the pouch of Douglas approach is easier during cesarean section. Clinical significance Internal iliac artery ligation is almost always performed as an emergency, though the need to perform it can be anticipated in advance and the gynecologist can be prepared for it. It is essential for gynecologists to be conversant with this life and a uterus-saving procedure. There are two approaches of doing this procedure and the choice is entirely on the individual. It may not be possible to approach the pouch of Douglas when there are dense adhesions as in case of a frozen pelvis. And it may be time-consuming to approach the internal iliac artery by dividing the round ligaments when there is postpartum hemorrhage. Therefore, it is useful to know both the approaches, because one might encounter a situation where one may find it difficult to follow the technique one is familiar with.

ABSTRACTIntroductionThe development of collateral vasculature is a key mechanism compensating for arterial occlusions in patients with peripheral artery disease (PAD). We aimed to examine the development of collateral pathways after ligation of native vessels in a porcine model of PAD.MethodsRight hindlimb Ischemia was induced in domestic swine (N=11, male, kg) using two different versions of arterial ligation. Version 1 (N=6) consisted of ligation/division of the right external iliac, profunda femoral (RPFA) and superficial femoral arteries (RSFA). Version 2 (N=5) consisted of the ligation of Version 1 with additional ligation/division of the right internal iliac artery (RIIA). Development of collateral pathways was evaluated with standard angiography at baseline (prior to arterial ligation) and at termination (4-8 weeks later). Relative luminal diameter of the arteries supplying the ischemic right hindlimb were determined by 2D angiography, as percent of the size of the distal aortic diameter.ResultsThe dominant collateral pathway that developed after version 1 ligation connected the RIIA to the RPFA and RSFA/popliteal artery. Mean luminal diameter (± standard error) of the RIIA at termination increased by 38% (P<0.05) compared to baseline. Two co-dominant collateral pathways developed in version: (i) from the common internal iliac trunk and left internal iliac artery to the reconstituted RIIA, which then supplied the RPFA and RSFA/popliteal arteries; and (ii) from left profunda artery to the reconstituted RPFA. Mean diameter of the common internal iliac trunk and left profunda artery both increased at termination in the range of 20% (p < 0.05).ConclusionTwo versions of hindlimb ischemia induction (right ilio-femoral artery ligation with and without right internal iliac artery ligation in swine produced differing collateral pathways, along with changes to the diameter of the inflow vessels (i.e., arteriogenesis). Radiographic and anatomical data of the collateral formation in this porcine model should have value in investigation of the pathophysiology of hindlimb ischemia, and assessment of angiogenic therapies as potential treatments for PAD.
