Aim: Infrainguinal bypass surgery stands as the predominant open surgical procedure for lower limb revascularization and is reserved for cases of intermittent claudication (IC) that have proven unresponsive to maximal medical management. Polypropylene monofilament sutures have been widely used for peripheral vascular surgery operations. Aim of this study is comparing this new type of suture with propylene sutures. Material and Methods: Between January 2022 and December 2022, two cohorts who underwent suprapopliteal femoropopliteal bypass surgery, each comprising 15 patients were included in the study. In Group I (polytetrafluoroethylene (PTFE) Group), PTFE served as the suture material, whereas in Group 2 (Non PTFE Group), polypropylene sutures were employed. All preoperative demographics, perioperative and postoperative data were collected carefully. Results: All patients underwent surgical interventions due to either rest pain or ischemic ulcers. Among the 30 patients, 11 fell into Fontaine class 4, while 19 were categorized as Fontaine class 3. Out of the 30 patients, 18 received cilostazol treatment. The mean age of the patient cohort was 66.97±7.4 years, with a mean body mass index of 29.03±6.2. When we compared the two groups, no statistically significant difference was found between groups according to demographic data. In the evaluation of intraoperative data, the mean operation time was 88.7±9.37 minutes, and the mean hemostasis time was 5.8±2.8 minutes. Group I (PTFE group) exhibited significantly lower hemostasis time and drainage levels on the first and second postoperative days (p<0.0001, p=0.03, and p=0.017, respectively). The use of absorbable hemostats were significantly less in PTFE suture group. Conclusion: The selection of sutures significantly influences the achievement of soft tissue approximation, reduced inflammation, suture hole leakage and capsule formation.
