Summary
Delayed embolectomy for arterial occlusion can be successful, even weeks after symptom onset. Intraoperative arteriography and direct distal approaches improve outcomes in these late surgical interventions.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Emergency Medicine
Background:
- Delayed embolectomy presents challenges in managing acute limb ischemia.
- Literature review indicates variable outcomes for late surgical interventions.
Purpose of the Study:
- To evaluate the efficacy of delayed embolectomy in acute limb ischemia.
- To identify factors influencing outcomes in late embolectomy procedures.
Main Methods:
- Case series of eight patients with delayed embolectomy.
- Comprehensive literature review of 241 additional patients.
- Analysis of time intervals from clinical onset to intervention.
Main Results:
- Successful arterial pulse restoration in 7 of 8 patients in the case series.
- Literature review: 172 viable extremities, 48 amputations, 30 deaths.
- Time intervals ranged from 2 days to 8 weeks post-clinical onset.
Conclusions:
- Delayed embolectomy can achieve limb salvage.
- Intraoperative arteriography is recommended for improved results.
- Direct operative approach to the distal arterial tree enhances outcomes.
