While several patterns of collateral blood flow around aortoiliac obstruction exist, the thoracic to lower-extremity pathway is often unrecognized. The principal blood vessels involved in this network are the internal mammary, superior epigastric, intercostal, inferior epigastric, and external iliac arteries. Two patients with aortoiliac occlusion experienced precipitation of rest pain because of transverse abdominal incisions for nonvascular procedures. Femoral anatomy was demonstrated arteriographically in two other patients by injection of contrast medium into the aortic arch. Patients with lower-extremity peripheral vascular disease may suffer exacerbation of their symptoms if the thoracic to lower-extremity collateral pathway is divided by poorly planned abdominal incisions. Ascending aortic or subclavian angiography is useful in some patients to define femoral arterial anatomy.
虽然围绕主-髂动脉阻塞存在几种侧支血流模式，但胸段至下肢的途径常常未被认识到。参与该网络的主要血管是胸廓内动脉、腹壁上动脉、肋间动脉、腹壁下动脉和髂外动脉。两名主-髂动脉闭塞患者因非血管手术的横向腹部切口而出现静息痛加剧。另外两名患者通过向主动脉弓注射造影剂，经动脉造影显示了股部解剖结构。如果胸段至下肢的侧支途径被规划欠佳的腹部切口切断，下肢周围血管疾病患者的症状可能会加重。升主动脉或锁骨下血管造影对一些患者确定股动脉解剖结构很有用。
