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 Background Ipsilateral branches of the deep femoral artery (DFA) are qualitatively identified as collateral arteries based on angiography after internal iliac artery (IIA) interruption. The purpose of this study was to quantitatively identify the major collateral pathway after unilateral IIA interruption during endovascular aortoiliac aneurysm repair to preserve the pelvic circulation and reduce the risk of ischemic complications. Methods The study population included 28 patients (mean age 76.3 years) with aortoiliac aneurysm who underwent endovascular aneurysm repair with unilateral IIA interruption from August 2012 to January 2020. The diameters of the bilateral preoperative and postoperative DFA, lateral femoral circumflex artery (LFCA), medial femoral circumflex artery (MFCA) and obturator artery (ObA) were measured on contrast-enhanced computed tomography using a 3-dimensional image analysis system. The measured values were evaluated and analyzed with a repeated measures two-way analysis of variance and Dunnett’s test. Results The postoperative diameters of the MFCA (P = 0.051) and ObA (P = 0.016) were observed to be larger than the preoperative diameters. Such increases in the MFCA (P < 0.001) and ObA (P < 0.001) diameters were only found to be significant on the unilateral side of the IIA interruption, and the diameter of the ipsilateral LFCA (P < 0.001) was also found to have significantly increased in size. However, no significant arterial extension was found on the contralateral side. Conclusions The ipsilateral MFCA-ObA pathway might therefore be a major collateral pathway arising from the DFA to preserve pelvic circulation after unilateral IIA interruption.

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.

The variations in blood vessels are common and have long received the attention of anatomists and surgeons. The true pelvic cavity usually refers to that part of pelvis, which has its bony walls, the sacrum and lower part of hip bone. This small area is well covered by bones and has important structures namely the pelvic viscera, pelvic floor muscles, vessels and nerves supplying it. The aim of the study was to know the branching pattern of internal iliac artery based on the Adachis classification, along with length and thickness of artery. The internal iliac artery was traced from its origin, course, branching pattern, length and thickness of the trunk of internal iliac artery was measured by using digital vernier calliper from its point of origin to bifurcation into anterior and posterior division. The length of right & left internal iliac artery ranged from 2.4 cm to 5.4 cm with average length of 3.943cm ± 0.859cm, whereas the length of left internal iliac artery ranged from 2.7cm to 4.7cm with average length of 3.610cm ± 0.626cm. Bilateral ligation of internal iliac artery is helpful in controlling postpartum haemorrhage. Applying ligatures on an anomalous blood vessel may lead to alarming haemorrhage. The most ideal point of ligation of internal iliac artery would be distal to its posterior division, since proximal ligation has been associated with buttock claudication and necrosis. Knowledge regarding the internal iliac artery and its branches is helpful in applying ligatures safely during pelvic surgeries.

The distribution pattern of internal iliac artery (IIA) implies its bifurcation to two branches, the anterior and the posterior trunks. According to previous research, IIA indicates several anatomical variations. The purpose of this study is to evaluate the types of these variations. The presence of these variations in the arteries is an important topic to urologists, gynecologists, radiologists, and general surgeons because they can be ruptured during surgical procedures in the perineal and pelvis region. Three databases were searched for the period from 1810 to January 2018 and a total of 75 studies were investigated. This study evaluated the branching of the internal iliac artery in several literatures and compared it with Adachi's classification. This finding can lead to improve surgical technique and safety in medical practice.

Iliolumbar Artery

Background: The Iliolumbar artery normally arises from the posterior division of Internal iliac artery. The main artery and its two branches supply the iliacus and lumbar region and other vital structures in that area. However, various studies conducted depict the differences in the pattern of its origin and course. Thus, the goal of this study was to discover the various origins of the iliolumbar artery, as well as its relationships with other surgically significant anatomical structures; the importance of which can prevent any intraoperative hemorrhages during surgery.Methods: The study was conducted in Department of Anatomy Lady Hardinge Medical College between 2019-2021. Pelvis of 12 formalin fixed adult cadavers (8 females, 4 males) were dissected to observe the iliolumbar artery. Its origin, caliber and course were measured using a digital vernier caliper. The relationship of iliolumbar artery was established with obturator nerve, lumbosacral trunk and sympathetic chain.Results: Iliolumbar artery was originating from trunk of internal iliac artery in 70.83% cases in which the mean distance of origin and mean caliber was more on right side. In the remaining 29.17% cases where the Iliolumbar artery was arising from posterior division of internal iliac artery, the mean distance of origin and mean caliber was higher on left side. The truncal origin of iliolumbar artery was predominant in females.Conclusions: The variant origin of the iliolumbar artery and its clinic-anatomical relationships have been highlighted to reduce iatrogenic artery trauma during surgery.
