Knowledge of its variations is helpful during gynecological and orthopedic surgical procedures.  Objectives To observe the branching pattern of IIA in the human pelvises and discuss its clinical implications.  Methods The study was conducted on 80 male hemipelvises (40 left halves and 40 right halves). The pelvic halves were obtained by making mid-line saw cuts through formalin embalmed adult human cadavers aged approximately 50-80 years. The IIA were dissected and cleaned. Variations of the internal iliac artery and its branches were noted. Relevant photographs were taken. Results were expressed as percentages.  Results Variations in the branching pattern were observed in 49 (61%) hemipelvises (right: 21, left: 28). Variations were more common (48%) in the branching pattern of the anterior division of IIA than the posterior division (20%). Variations of the main trunk were observed in 29% of cases. In 3% of cases, the IIA did not divide into two divisions. Among the individual branches, the iliolumbar artery showed variations in 29% of cases and the obturator artery in 25%. A common trunk of the internal pudendal and middle rectal arteries was found in 24% of cases and variations of the inferior gluteal artery were seen in 18% of cases.  Conclusions The study showed a high rate of occurrence of variant IIA branching patterns. Understanding the anatomical variations of the IIA and its branches is essential to minimize intraoperative blood loss and other complications during pelvic surgeries.<\/jats:p>","DOI":"10.1590\/1677-5449.202400752","type":"journal-article","created":{"date-parts":[[2025,4,2]],"date-time":"2025-04-02T06:54:33Z","timestamp":1743576873000},"source":"Crossref","is-referenced-by-count":0,"title":["Variations in the branching pattern of the internal iliac artery and its implications in trauma and surgery \u2013 a South Indian cadaveric study"],"prefix":"10.1590","volume":"24","author":[{"given":"Satheesha Nayak","family":"Badagabettu","sequence":"first","affiliation":[{"name":"Manipal Academy of Higher Education,  India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1298-6746","authenticated-orcid":false,"given":"Ashwini Aithal","family":"Padur","sequence":"additional","affiliation":[{"name":"Manipal Academy of Higher Education,  India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Surekha Devadasa","family":"Shetty","sequence":"additional","affiliation":[{"name":"Manipal Academy of Higher Education,  India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2025]]},"reference":[{"key":"ref1","series-title":"Gray\u2019s anatomy: the anatomical basis of medicine and surgery.","author":"Williams PL","year":"2008","edition":"40th"},{"issue":"2","key":"ref2","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1007\/s00276-010-0716-3","article-title":"Branching patterns of the male internal iliac artery: imaging findings","volume":"33","author":"Bilhim T","year":"2011","journal-title":"Surg Radiol Anat"},{"issue":"2","key":"ref3","first-page":"23","article-title":"Role of internal iliac artery ligation in control of pelvic hemorrhage","volume":"1","author":"Bangal V","year":"2009","journal-title":"Pravara Med Rev"},{"issue":"5","key":"ref4","first-page":"4305","article-title":"Angiographic evaluation of the internal iliac artery branch in pelvic tumour patients: diagnostic performance of multislice computed tomography angiography","volume":"17","author":"Li L","year":"2019","journal-title":"Oncol Lett"},{"issue":"3","key":"ref5","doi-asserted-by":"crossref","first-page":"356","DOI":"10.1111\/j.1471-0528.2006.01235.x","article-title":"Internal iliac artery ligation for arresting postpartum haemorrhage","volume":"114","author":"Joshi VM","year":"2007","journal-title":"BJOG"},{"issue":"9","key":"ref6","doi-asserted-by":"crossref","first-page":"897","DOI":"10.1590\/S1807-59322009000900011","article-title":"Variability in the origin of the obturator artery","volume":"64","author":"Pai MM","year":"2009","journal-title":"Clinics"},{"key":"ref7","series-title":"Langman\u2019s essential medical embryology.","first-page":"339","author":"Sadler TW","year":"2012"},{"key":"ref8","first-page":"111","article-title":"Die tyischen verzweigsform der arteria hypogastrica","volume":"8","author":"Jastchinski S","year":"1891","journal-title":"Int Mschr Anat Physiol."},{"key":"ref9","series-title":"Das Arteriensystem der Japaner.","first-page":"136","author":"Adachi B","year":"1928"},{"issue":"4","key":"ref10","first-page":"423","article-title":"Variations in origin of the parietal branches of the internal iliac artery","volume":"86","author":"Braithwaite JL","year":"1952","journal-title":"J Anat"},{"issue":"4","key":"ref11","doi-asserted-by":"crossref","first-page":"333","DOI":"10.2739\/kurumemedj.45.333","article-title":"Statistical study of the branching of the human internal iliac artery","volume":"45","author":"Yamaki K","year":"1998","journal-title":"Kurume Med J"},{"issue":"2","key":"ref12","doi-asserted-by":"crossref","first-page":"63","DOI":"10.31051\/1852.8023.v6.n2.14126","article-title":"Internal iliac artery classification and its clinical significance.
