Article Synopsis
- Portugal has a high prevalence of dialysis patients who are more prone to complications from chronic limb threatening ischemia (CLTI), leading the study to compare outcomes of dialysis vs. non-dialysis patients undergoing infrapopliteal bypass.
- The study involved 352 bypass procedures from 2012 to 2019, with over 14% performed on dialysis patients; main outcomes included 1-year freedom from CLTI and other vital rates.
- Results showed that dialysis patients had significantly lower primary patency rates (39% vs. 64%), but no major differences in overall success rates like freedom from CLTI, limb-salvage, or survival between the two groups.
Background: To analyze the outcomes of heparin-bonded expanded polytetrafluoroethylene (HePTFE) graft as an alternative conduit in infrapopliteal revascularization of chronic limb-threatening ischemia (CLTI) in the absence of an autologous vein conduit.
Methods: A single-center retrospective analysis of patients with CLTI submitted to infrapopliteal bypasses with autologous vein graft (VEIN group) or HePTFE graft (HePTFE group) was implemented. Primary end points were freedom from CLTI at 12 months and recurrence of CLTI at 3 years.
Objective: We evaluated the relationship of the global limb anatomic staging system (GLASS) stage with the clinical outcomes for patients with chronic limb-threatening ischemia (CLTI) who had undergone distal bypass with vein grafting.
Methods: We performed a single-center, retrospective analysis of patients with CLTI who had undergone distal bypass with vein grafting from January 2012 to December 2019. The primary end point was freedom from CLTI, including amputation-free survival, complete wound healing, and no ischemic rest pain.
