In order to demonstrate common pressure gradients and peripheral arterial pressure in ileo-femoro-popliteal arteries before and after reconstruction for atherosclerosis, intra-operative pressure measurements were performed on 204 patients. Before reconstruction, the pressure differential was 44.3 mmHg in femoro-popliteal arteries and 29.0 mmHg in the iliac arteries. This was reduced to 8.4 and 4.1 mmHg by the reconstructions. In patients with femoro-popliteal disease, the pressure gradient was higher when gangrena or rest pain were present than when claudication was the principal symptom. When the iliac arteries were mainly involved, no such difference was seen. Postoperative gradients were slightly higher in arteries subjected to primary failure than in vessels remaining patent. The blood flow increase from intra-arterial papaverine injections accentuated existing pressure gradients and frequently disclosed gradients not manifest at basal flow rates.
为了展示动脉粥样硬化重建前后髂股腘动脉的常见压力梯度和外周动脉压，对204例患者进行了术中压力测量。重建前，股腘动脉的压差为44.3 mmHg，髂动脉为29.0 mmHg。重建后分别降至8.4 mmHg和4.1 mmHg。在患有股腘疾病的患者中，存在坏疽或静息痛时的压力梯度高于以间歇性跛行为主要症状时。当主要累及髂动脉时，未观察到这种差异。原发性失败的动脉术后梯度略高于仍保持通畅的血管。动脉内注射罂粟碱后血流量增加加剧了现有的压力梯度，并常常揭示出基础流速时未表现出的梯度。
