Summary
This study shows that combining local thrombolysis with recombinant tissue plasminogen activator (rtPA) and prompt surgical repair effectively treats acute limb ischemia from popliteal artery aneurysms, reducing amputation rates.
Area of Science:
- Vascular Surgery
- Endovascular Therapy
- Acute Limb Ischemia
Context:
- Popliteal artery aneurysms can cause acute limb ischemia due to thrombosis.
- Traditional surgical repair carries risks of limb loss.
- A combined endovascular and surgical approach offers a potential alternative.
Purpose:
- To evaluate the efficacy of a combined endovascular and surgical treatment for acute limb ischemia caused by popliteal artery aneurysms.
- To assess outcomes including limb salvage, patency rates, and complications.
- To compare this combined approach with primary surgical treatment.
Summary:
- Ten patients with acute limb ischemia from popliteal artery aneurysms were treated with 24-48 hours of local thrombolysis using recombinant tissue plasminogen activator (rtPA), followed by aneurysm exclusion and vascular reconstruction within 24 hours.
- No deaths, amputations, or graft occlusions occurred during hospitalization.
- Medium-term results showed 100% patency with autologous vein grafts, but poorer outcomes with prostheses, especially in femoropopliteal bypasses.
Impact:
- This combined therapy significantly increases the chances of saving the affected extremity.
- It markedly reduces the necessity for amputation compared to primary surgical treatment.
- The use of autologous vein grafts is crucial for long-term patency in vascular reconstructions for popliteal artery aneurysms.
