In this prospective study we investigated the site, occurrence, and development of stenoses and occlusions following recanalization of superficial femoral artery occlusions.
Recanalization of an occluded femoropopliteal artery was attempted in 62 patients. Follow-up examinations included clinical examination and color-flow duplex scanning at regular intervals. Arteriography was used to determine the localization of the recurrent disease relative to the initially occluded segment.
During a mean follow-up of 23 months (range 0-69 months) 14 high-grade restenoses, indicated by a peak systolic velocity ratio >> 3.0, were detected by color-flow duplex scanning. Occlusion of the treated segment occurred in 11 patients. The cumulative 3-year primary patency rate for high-grade restenoses and occlusions combined was 44% (SE 9%). By arteriographic examination the site of restenosis was localized in the distal half of the treated vessel segment in 16 of 21 cases.
Most restenoses and occlusions occurred during the first year and most disease developed at the previous intervention site. The site of restenosis is more frequently in the distal part of the initially treated segment, a finding that may have therapeutic implications.
在这项前瞻性研究中，我们调查了股浅动脉闭塞再通术后狭窄和闭塞的部位、发生率及发展情况。
对62例患者尝试进行闭塞的股腘动脉再通术。随访检查包括定期的临床检查和彩色血流双功扫描。动脉造影用于确定复发性疾病相对于最初闭塞节段的定位。
在平均23个月（范围0 - 69个月）的随访期间，彩色血流双功扫描检测到14例峰值收缩速度比>> 3.0的高度再狭窄。11例患者出现治疗节段闭塞。高度再狭窄和闭塞合并的3年累计原发性通畅率为44%（标准误9%）。通过动脉造影检查，21例中有16例再狭窄部位位于治疗血管节段的远端一半。
大多数再狭窄和闭塞发生在第一年，且大多数病变发生在先前的干预部位。再狭窄部位更常见于最初治疗节段的远端，这一发现可能具有治疗意义。
