Angiographic demonstration of obstructive aortoiliac disease is of paramount importance prior to surgery. Obstructive disease in the femoral popliteal system can only be surgically relieved if inflow is adequate. Severely stenotic lesions may be missed by angiography due to the oblique course of the iliac arteries and inability to obtain right angle views. Translumbar downstream catheterization of the abdominal aorta and puncture of both femoral arteries allows simultaneous pressure recordings. The injection of 30 mg of papaverine into the femoral artery assures maximal vasodilatation mimicking conditions under exercise. A minimal gradient at rest may become obvious following the injection of papaverine, indicating hemodynamically significant disease and warranting surgical correction. The technique has proved to be simple and valuable, and there have been no complications.
在手术前，对阻塞性主-髂动脉疾病进行血管造影显示至关重要。只有在流入道充足的情况下，股-腘动脉系统的阻塞性疾病才能通过手术缓解。由于髂动脉走行倾斜且无法获得直角视图，血管造影可能会漏诊严重狭窄病变。经腰段对腹主动脉进行下游导管插入术并穿刺双侧股动脉可同时记录压力。向股动脉内注射30毫克罂粟碱可确保最大程度的血管扩张，模拟运动状态下的情况。注射罂粟碱后，静息时的最小压差可能会变得明显，这表明存在血流动力学意义重大的疾病，需要进行手术矫正。该技术已被证明简单且有价值，并且没有并发症。
