Summary
Below-knee amputation healing is challenging. A novel hybrid technique using retrograde balloon angioplasty improved arterial inflow, aiding wound healing in critical limb ischemia patients.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Below-knee amputation is common for lower extremity gangrene and critical limb ischemia.
- Non-healing amputations lead to morbidity, requiring further surgery.
Observation:
- A case report details a hybrid technique for amputation site revascularization.
- This involved retrograde transamputation revascularization using balloon angioplasty.
Findings:
- The proximal, retrograde approach facilitated crossing infrainguinal chronic total occlusions (CTOs).
- This intervention successfully improved arterial inflow to the amputation site.
Implications:
- This technique offers a potential solution for improving below-knee amputation healing rates.
- It may reduce the need for further debridement or above-knee amputation conversion.
