The success rate and time taken for recanalization was determined in a prospective study of 82 consecutive unselected patients (53 men, 29 women; mean age 65.7 +/- 13, from 28 to 88 years). There were 106 complete occlusions of infrarenal arteries and a hydrophilic guide wire with a special 5-F recanalization catheter was used. Mean occlusion length was 12.97 +/- 10 cm (from 1 cm-45 cm). 79.3% of occlusions were in the femoro-popliteal territory, 6.6% were iliac and 14.1% tibial. 101 of the 106 occlusions were recanalized (95.3%). Mean recanalization time was 120.8 +/- 228.1 s (from 1 s-1440 s), mean recanalization velocity was 0.11 cm/s. The majority of obstructions could be recanalized in less than one minute. The five occlusions which could not be recanalized were distal lesions in the superficial femoral artery and which were longer than 10 cm; two were calcified. There were no complications resulting from the recanalization apart from three perforations which were clinically not apparent. Consequent angioplasty proved successful in 78.1% of these patients.
在一项对82例未经挑选的连续患者（53例男性，29例女性；平均年龄65.7±13岁，年龄范围28至88岁）的前瞻性研究中，确定了再通成功率和所需时间。共有106处肾下动脉完全闭塞，使用了带有特殊5F再通导管的亲水导丝。平均闭塞长度为12.97±10厘米（范围1厘米至45厘米）。79.3%的闭塞位于股腘动脉区域，6.6%位于髂动脉，14.1%位于胫动脉。106处闭塞中有101处实现了再通（95.3%）。平均再通时间为120.8±228.1秒（范围1秒至1440秒），平均再通速度为0.11厘米/秒。大多数阻塞可在不到一分钟内实现再通。五处未能再通的闭塞是股浅动脉远端病变且长度超过10厘米；两处有钙化。除了三处临床上不明显的穿孔外，再通未引发其他并发症。在这些患者中，后续血管成形术成功率为78.1%。
