Aortofemoral graft for multilevel occlusive disease. Predictors of success and need for distal bypass
Insights
Aortofemoral reconstruction effectively relieved ischemic symptoms in 74% of patients with multilevel occlusive disease. Hemodynamic inflow disease strongly predicted good outcomes, guiding surgical decisions for complex cases.
Area of Science:
- Vascular Surgery
- Cardiovascular Medicine
- Surgical Outcomes Research
Background:
- Multilevel occlusive disease presents complex challenges in vascular surgery.
- Aortofemoral reconstruction is a primary surgical intervention for lower extremity ischemia.
Purpose of the Study:
- To review outcomes of aortofemoral reconstruction in patients with multilevel occlusive disease.
- To identify predictors of successful outcomes and guide surgical strategy.
Main Methods:
- Retrospective review of 181 consecutive patients undergoing aortofemoral reconstruction.
- Correlation of 42 variables with patient outcomes.
- Multivariate analysis to identify independent predictors of outcome.
Main Results:
- 74% of patients achieved satisfactory symptom relief with proximal operation alone.
- 12 variables were statistically significant predictors of outcome; 5 were independent indicators.
- Hemodynamically significant inflow disease strongly correlated with good results.
- Noninvasive laboratory variables aided in assessing hemodynamic compensation.
Conclusions:
- Hemodynamic inflow status is a key predictor of successful aortofemoral reconstruction.
- Careful evaluation of multiple factors, not a single variable, aids in selecting patients for combined proximal and distal grafting.
- Synchronous aortofemoral and femoropopliteal grafts may benefit a select group of patients.
Abstract:
Results of aortofemoral reconstruction of 181 consecutive patients with multilevel occlusive disease were reviewed and correlated with possible predictors of outcome. Overall, 74% of patients attained satisfactory relief of ischemic symptoms with proximal operation alone. Forty-six patients (26%) had an unsatisfactory result, 31 (17%) of whom underwent distal bypass grafts. Of 42 variables studied, 12 achieved statistical significance as predictors of outcome, and multivariate analysis identified five factors an independent indicators. Factors documenting hemodynamically significant inflow disease were associated most strongly with a good result. Several noninvasive laboratory variables were found helpful, particularly in assessing the hemodynamic compensation of distal disease. While no single variable reliably indicated the definite need for distal grafting, careful consideration of important factors together with the clinical situation will aid the surgeon in selection of the small group of patients best treated by synchronous aortofemoral and femoropopliteal grafts.
