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.
RESUMO
A artéria ilíaca interna (AII) é um dos ramos da artéria ilíaca comum e supre as vísceras da pelve, a parte musculoesquelética da pelve, a região glútea, a região medial da coxa e o períneo. Durante a dissecção de rotina realizada em um cadáver do sexo masculino para estudantes de Medicina, observamos uma variação no curso e padrão de ramificação da AII esquerda. A artéria deu origem a dois troncos comuns e então à artéria retal média, artéria vesical inferior e artéria vesical superior. O primeiro tronco comum, ligeiramente maior, deu origem a uma artéria sem nome, à artéria sacral lateral e à artéria glútea superior. O segundo tronco comum, menor, adentrou a região glútea através do forame ciático maior, abaixo do músculo piriforme, e apresentou um padrão estrelado de ramificação na parte profunda do músculo glúteo máximo. Duas das artérias que formaram o padrão estrelado foram a artéria pudenda interna e a artéria glútea inferior. Os outros dois ramos eram musculares.
