Management of combined segment disease
Insights
Aortofemoral bypass is superior to axillofemoral bypass for combined segment disease in limb salvage. A predictive index can identify limbs that may not benefit from aortofemoral bypass alone, guiding surgical decisions.
Area of Science:
- Vascular Surgery
- Surgical Outcomes
- Peripheral Artery Disease
Background:
- Combined segment disease presents a challenge in peripheral artery disease management.
- Revascularization strategies aim to improve limb perfusion and salvage.
- Distinguishing between limb salvage and claudication indications is crucial.
Purpose of the Study:
- To compare the efficacy of aortofemoral bypass versus axillofemoral bypass for combined segment disease.
- To evaluate the utility of a predictive index derived from segmental plethysmography.
- To assess the outcomes of synchronous procedures in selected cases.
Main Methods:
- Retrospective analysis of 148 inflow procedures, with 85 for combined segment disease.
- Comparison of clinical and functional outcomes between aortofemoral and axillofemoral bypass.
- Application of a predictive index derived from segmental plethysmography for patient selection.
Main Results:
- Aortofemoral bypass demonstrated superior clinical and functional results compared to axillofemoral bypass in limbs with combined segment disease requiring salvage.
- Outcomes for both procedures were comparable in patients with claudication.
- The predictive index effectively identified limbs unlikely to respond to aortofemoral bypass alone.
- Synchronous procedures in selected limbs with ischemic lesions and specific predictive index values yielded favorable early results with low morbidity.
Conclusions:
- Aortofemoral bypass is the preferred method for limb salvage in combined segment disease.
- The predictive index is a valuable tool for preoperative patient selection.
- Synchronous procedures offer a viable option for complex cases, improving functional outcomes.
Abstract:
Eighty-five of 148 inflow procedures were performed for combined segment disease. Our study shows that aortofemoral bypass is clinically and functionally superior to axillofemoral bypass in limbs with combined segment disease and hemodynamic criteria for limb salvage. The results of these two procedures are comparable for claudicant limbs. A derivative of segmental plethysmography, the predictive index, can select preoperatively those limbs that will fail to respond to aortofemoral bypass alone. Finally, either in limbs selected for aortofemoral bypass with both ischemic tissue lesions and a predictive index greater than 0.2 or in limbs selected for axillofemoral bypass with ischemic tissue lesions alone, a synchronous procedure can be performed with relatively low morbidity and excellent early functional results.
