Abstract
Background: Bifurcated vein grafts have been described in reconstructive microsurgery. No comparative studies have been published in lower limb arterial revascularization. The aim of this study was to compare non-reversed bifurcated vs. single vein graft in patients with critical limb-threatening ischemia (CLTI) undergoing lower limb distal bypass.
Methods: Between January 2015 and December 2021 193 CLTI patients have been treated at our center with vein bypass, and distal anastomosis on infrapopliteal vessels; 137 patients (71%) received a single graft (Group SIN), and 56 patients (29%) had a bifurcated bypass (Group BIF). Primary outcomes measures were time to healing, primary patency, primary assisted patency, secondary patency, and limb salvage. Two-year outcomes according to Kaplan-Meier curves were evaluated and compared.
Results: Both groups were homogeneous in terms of demographic data, preoperative risk factors, and clinical presentation except for an elderly age in Group BIF (77.5 vs. 71.5 years; P<0.001). Intraoperative technical success was achieved in all patients. Overall median duration of follow-up was 19 months (interquartile range 9-36). Wound healing did not differ between the two groups (77.4% Group SIN vs. 73.2% Group BIF; P=0.33). Mean time to healing was faster in Group BIF (2.4 vs. 6.8 months; P<0.001). At 2-year follow-up there were no differences between the two groups in terms of primary patency (71.4% Group SIN vs. 54% Group BIF; P=0.10), primary assisted patency (81.7% Group SIN vs. 76.4% Group BIF; P=0.53), secondary patency (85.1% Group SIN vs. 80.9% Group BIF; P=0.79), and limb salvage (92.3% Group SIN vs. 87.2% Group BIF; P=0.64).
Conclusions: Bifurcated graft improved time to healing in CLTI patients undergoing infrapopliteal non-reversed vein bypass. Two-year overall patencies and limb salvage did not differ accordingly to vein graft configuration (single vs. bifurcated).
背景:分岔静脉移植物在重建显微外科中已经被描述过。下肢动脉血运重建术的比较研究尚未发表。本研究的目的是比较危重肢体缺血(CLTI)患者行下肢远端旁路手术的非逆转分支静脉移植与单静脉移植。方法:2015年1月至2021年12月,我院对193例CLTI患者行静脉搭桥、远端吻合腘下血管;137例患者(71%)接受了单次移植(SIN组),56例患者(29%)接受了分流搭桥(BIF组)。主要结局指标为愈合时间、原发性通畅、原发性辅助通畅、继发性通畅和肢体保留。根据Kaplan-Meier曲线评估和比较两年后的预后。结果:两组在人口统计学数据、术前危险因素和临床表现方面均相同,除了BIF组的年龄较大(77.5 vs 71.5岁;结论:分叉移植物改善了行膝下非逆行静脉旁路治疗的CLTI患者的愈合时间。两年的总体通畅度和肢体保留度没有相应的静脉移植配置差异(单静脉vs分静脉)。
