The absence or dysplasia of the iliac artery(IA) is an exceedingly rare condition, with limited cases documented in the literature. In this report, we present a case of hypoplasia of the right external iliac artery (EIA) in a 69-year-old male patient. The patient presented with right lower abdominal pain attributed to an aneurysm of the right internal iliac artery (IIA), yet notably, there was no evidence of lower limb ischemia at the time of consultation. Computed tomography angiography (CTA) of the aorta revealed a slender and occluded right EIA. Additionally, aneurysms were identified in the abdominal aorta (AA), the common iliac artery (CIA), and the right IIA, with collateral circulation involving the deep femoral artery and internal pathways. We performed aortoiliac aneurysm repair with a bifurcated synthetic graft on the patient's AA and iliac artery (IA), successfully excising the abdominal aorta aneurysms (AAA) and the CIA aneurysm. Postoperatively, thrombosis of the internal iliac aneurysm was observed, and the patient experienced a resolution of pain symptoms in the right lower abdomen. This paper delineates the vascular variations and treatment strategies employed and provides a review of the existing literature on IA malformations.
髂动脉（IA）缺如或发育异常是一种极为罕见的病症，文献中记载的病例有限。在本报告中，我们呈现了一例69岁男性患者右髂外动脉（EIA）发育不全的病例。该患者因右髂内动脉（IIA）动脉瘤出现右下腹疼痛，但值得注意的是，就诊时未发现下肢缺血的证据。主动脉计算机断层血管造影（CTA）显示右EIA纤细且闭塞。此外，在腹主动脉（AA）、髂总动脉（CIA）和右IIA中发现了动脉瘤，伴有经股深动脉和内部路径的侧支循环。我们对患者的AA和髂动脉（IA）进行了带分叉人工血管的主髂动脉瘤修复术，成功切除了腹主动脉瘤（AAA）和CIA动脉瘤。术后观察到髂内动脉瘤血栓形成，患者右下腹疼痛症状缓解。本文阐述了所采用的血管变异和治疗策略，并对IA畸形的现有文献进行了综述。
