Congenital anatomical variations of the terminal aorta are rare. Given the increasing number of endovascular and laparoscopic procedures, such variations are likely to assume greater clinical significance. A 15-year-old male sustained a pelvic vascular injury following a stab to the left gluteus. Computed tomographic angiography and digital subtraction angiography demonstrated a left superior gluteal artery pseudoaneurysm and absence of the common iliac arteries consistent with congenital quadrifurcation of the terminal aorta. The patient was subsequently treated with endovascular coil embolisation with a good angiographic and clinical outcome.
Terminal aortic variants are rare and given the increasing number of interventional endovascular procedures performed in the aorta, an awareness of the potential anatomical configurations of the distal aortic branches is of increasing relevance. The authors describe the imaging findings of one such anatomical variant.
终末主动脉的先天性解剖变异很少见。鉴于血管内和腹腔镜手术的数量不断增加，此类变异可能具有更大的临床意义。一名15岁男性在左臀肌被刺伤后发生盆腔血管损伤。计算机断层血管造影和数字减影血管造影显示左臀上动脉假性动脉瘤，且髂总动脉缺如，符合终末主动脉先天性四分支。该患者随后接受了血管内弹簧圈栓塞治疗，血管造影和临床结果良好。
终末主动脉变异很少见，鉴于在主动脉中进行的介入性血管内手术数量不断增加，了解主动脉远端分支的潜在解剖结构越来越重要。作者描述了一种此类解剖变异的影像学表现。
