Abstrakt		Background: The outcome of percutaneous transluminal angioplasty (PTA) of peripheral arterial lesions is influenced by several factors, including the haemodynamic conditions. Our study tested: (a) whether infrapopliteal run-off after completed PTA influenced the time course of restenosis/reocclusion of the femoropopliteal arterial segment, and (b) whether worsening of infrapopliteal run-off influenced the long-term femoropopliteal patency after PTA. Patients and methods: Among 245 patients treated by femoropopliteal PTA we enrolled 176 patients who consented to regular follow-up. Concomitant infrapopliteal PTA was performed whenever feasible. The technical success of PTA and the patency of calf arteries were assessed by angiography. Infrapopliteal run-off was scored by a modification of the Society for Vascular Surgery criteria. The treated patients' limbs were divided into a group with good infrapopliteal run-off and a group with compromised run-off. Follow-up examination of the femoropopliteal arterial segment was performed by vascular ultrasonography (US) 1, 6 and 12 months after PTA, and an adverse outcome was defined by a > or = 50 % stenosis, i.e., at least doubling of the maximal systolic velocity, or occlusion - evidenced by the absence of flow. The patency of calf arteries was re-assessed by US 12 months after PTA. Results: One month after femoropopliteal PTA 19 / 83 (23 %) of patients with compromised run-off developed the combined end-point of restenosis or reocclusion in comparison to 10 / 93 (11 %) with good run-off (p = 0.03). After 6 months the incidence of restenosis/reocclusion had increased in both groups at an approximately equal rate, but the differences were no longer significant: 39 / 80 (49 %) in the compromised run-off group vs. 36 / 83 (43 %) in the good run-off group after 6 months, p = 0.49, and 42 / 73 (57 %) vs. 38 / 73 (52 %) after 12 months, p = 0.51.
