Data was reviewed on patients presenting with lower limb-threatening ischaemia to a single vascular unit between September 1984 and December 1990. Three hundred and thirty patients underwent either femoro-popliteal or femoro-infrapopliteal reconstructive surgery and 316 primary amputations were performed on 281 patients. Sixty-three secondary amputations were performed following a femoro-distal bypass failure. The below-knee amputation to above-knee amputation ratio (BKA/AKA) was 1.0 in the primary amputation group to 0.91 in the secondary amputation group. A direct comparison cannot be made as the patients represent two separate clinical groups. The ratio of reconstructive operations to primary amputations more than doubled between the first and second halves of the study. The BKA:AKA ratio in the secondary amputation group and the total number of secondary amputations remained relatively constant. This study supports the view that previous femoro-distal surgery does not adversely affect the overall outcome of amputation.
对1984年9月至1990年12月间因下肢严重缺血就诊于单一血管科的患者资料进行了回顾。330例患者接受了股腘或股腘以下重建手术，281例患者进行了316次一期截肢手术。63例二期截肢手术是在股腘以下旁路手术失败后进行的。一期截肢组膝下截肢与膝上截肢的比例（BKA/AKA）为1.0，二期截肢组为0.91。由于这些患者代表两个不同的临床组，因此无法进行直接比较。在研究的前半段和后半段之间，重建手术与一期截肢的比例增加了一倍多。二期截肢组的BKA:AKA比例和二期截肢的总数保持相对稳定。本研究支持以下观点，即先前的股腘以下手术不会对截肢的总体结果产生不利影响。
