To investigate the efficacy of A-V impulse technology (A-V) for oedema prevention and treatment following PTFE femoropopliteal surgery.
Prospective randomized clinical trial.
36 patients undergoing PTFE femoropopliteal bypass reconstructions, either being treated postoperatively with a compression stocking (CS) (Group-1, n = 19) or with A-V (Group-2, n = 17).
Patients in treatment group-1 used a CS postoperatively during 1 week day and night, patients in group-2 were treated with A-V postoperatively at night during one week. The lower leg circumference was measured preoperatively and at five postoperative time points.
Limb circumference has increased postoperatively on day 1 (CS 1.5%/A-V 1.4%), on day 4 (5.7%/6.3%), on day 7 (6.6%/6.1%), on day 14 (7.9%/7.7%) and on day 90 (5.8%/5.2%). Differences between treatment groups were not significant. A re-operation gives a significant 3.9% increase in circumference as compared to a first operation (95% CI: 1.5-6.4%; p = 0.002).
No significant differences were found in the extent of developed edema between the groups following PTFE femoropopliteal bypass surgery. A redo peripheral bypass operation results in significantly more postoperative oedema than a first-time performed bypass operation.
研究 A-V 脉冲技术（A-V）在 PTFE 股腘旁路手术后预防和治疗水肿的效果。
前瞻性随机临床试验。
36 例接受 PTFE 股腘旁路重建术的患者，术后分别使用压缩袜（CS）（19 例，组 1）或 A-V（17 例，组 2）治疗。
组 1 患者术后 1 周内白天和黑夜使用 CS，组 2 患者术后夜间使用 A-V 治疗 1 周。术前和术后 5 个时间点测量小腿周径。
术后第 1 天（CS 1.5%/A-V 1.4%）、第 4 天（5.7%/6.3%）、第 7 天（6.6%/6.1%）、第 14 天（7.9%/7.7%）和第 90 天（5.8%/5.2%），小腿周径均增加。治疗组间差异无统计学意义。与初次手术相比，再次外周旁路手术的周长增加了 3.9%（95%CI：1.5-6.4%；p=0.002）。
在 PTFE 股腘旁路手术后，两组之间发生的水肿程度没有显著差异。再次外周旁路手术比初次旁路手术术后水肿明显更多。
