Multivariate Cox Regression Analysis of Covariates for Patency Rates After Femorodistal Vein Bypass Grafting

Limb salvage after infrainguinal bypass graft failure

“…16 This has been achieved despite clearly increasing comorbidity in patients undergoing this operation. 17 Although early patency is routinely achieved, the life span of the graft is highly variable, and a significant percentage of grafts fail in subsequent years. [2][3][4][5][6]8,9,18,19 This attrition of functioning grafts remains the most important and frustrating limitation of the procedure.…”

Patient recovery after infrainguinal bypass grafting for limb salvage

“…Most reports contain the results of institutions' entire experience with IB, which means that many patients are included who have short-term follow-up. The effect of "frontloading" data evaluated by life table is to favorably bias the results when long-term outcome is censored by death of many patients, as described by Myers et al 27 Patency assesses the results of an individual operation. Limb salvage assesses the results of an operation on a single limb.…”

Postoperative and amputation-free survival outcomes after femorodistal bypass grafting surgery: Findings from the Department of Veterans Affairs National Surgical Quality Improvement Program

“…Long-term primary and assisted patency results are known to vary significantly by factors such as whether patients have disabling intermittent claudication or critical leg ischemia (rest pain, gangrene, skin ulcers), by type of graft material (artificial vs autologous vein grafts), and by site of distal anastomosis. 4,5 Hunink et al 2 found adjusted 5-year patency rates that ranged from more than 80% for saphenous vein grafts for claudication to only 33% for polytetrafluoroethylene grafting for below-knee critical ischemia. Given this wide range of results, standardized preoperative risk assessment is fundamental for evaluating outcomes of lower-extremity bypass grafting surgery.…”
