Summary
Infrainguinal bypass surgery for limb salvage maintains independence and ambulation in most patients. Preoperative status is the strongest predictor of postoperative outcomes, with survival influenced by other health conditions, not the bypass itself.
Area of Science:
- Vascular Surgery
- Limb Salvage Surgery
- Patient Outcomes
Background:
- Functional outcomes after infrainguinal bypass (IB) are typically assessed globally, not by specific goals like independent living and ambulation.
- Evaluating IB for limb salvage (LS) requires criteria tailored to maintaining patient independence.
Purpose of the Study:
- To assess functional outcomes of infrainguinal bypass (IB) for limb salvage (LS) based on preoperative and postoperative living situation and ambulatory status.
- To determine if IB procedures effectively maintain independent living and ambulation in patients undergoing LS.
Main Methods:
- Retrospective analysis of 513 patients undergoing IB for LS (1980-1995).
- Assessed living situation (independent/dependent) and ambulatory status preoperatively and 6 months postoperatively.
- Multivariate analysis identified risk factors and predictors of outcome.
Main Results:
- 92% of patients lived independently and 91% were ambulatory preoperatively.
- Postoperatively, 99% of previously independent patients remained independent, and 97% of ambulatory patients remained ambulatory.
- Graft patency was 92% at 6 months, with a 2.7% operative mortality rate. Preoperative status strongly predicted 6-month outcomes (p < 0.0001).
Conclusions:
- Preoperative independence and ambulation are key predictors of postoperative function after IB for LS.
- IB for LS demonstrates low operative mortality and high rates of maintaining independence (99%) and ambulation (97%).
- Long-term survival is primarily affected by comorbidities, not the infrainguinal bypass procedure itself.
