In the middle of the third week of embryonic development, the primordial heart and vascular system begin to develop (Ozgüner and Sulak 2011). The arterial system arises from both ectoderm- and mesoderm-derived angiogenic cells. The aortic arches and right and left dorsal aortae unite during development to form the descending aorta, generating posterolateral intersegmental branches throughout the thorax (Ozgüner and Sulak 2011). As the dorsal aorta descends through the abdomen, branches to the gastrointestinal and renal systems are formed, including the intersegmental arteries (Ozgüner and Sulak 2011). The umbilical arteries arise from the dorsal aorta and disconnect from it after anastomosing with the intersegmental arteries. The common iliac arteries then arise from the proximal portions of the patent umbilical arteries (Szpinda et al. 2012). The external iliac artery arises from the common iliac arteries (Bergman et al. 2016). The fifth intersegmental artery (fifth dorsal branch of the aorta) anastomoses with the umbilical artery to produce the internal iliac artery (Bergman et al. 2016), which develops anterior and posterior divisions that subsequently give off further branches to the pelvic area. This region is initially vascularized through a capillary plexus (Bergman et al. 2016), which progresses into an arterial pattern thanks to the persistence of necessary vascular channels and the regression of others, forming the branches of the internal iliac artery; these include the inferior vesical/vaginal artery (Bergman et al. 2016). The variability in branching often seen within the iliac vessels can be attributed to genetics and the vascular demands of subsequent tissues (Balcerzak et al. 2022).
