Insights
Subintimal angioplasty effectively treats chronic lower extremity arterial occlusive disease, offering high limb salvage and low complications. Selective re-entry device use and anti-platelet drugs significantly improve outcomes.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Background:
- Chronic arterial occlusive disease of the lower extremity significantly impacts patient mobility and quality of life.
- Endovascular interventions are increasingly utilized for treating peripheral artery disease.
Purpose of the Study:
- To evaluate the clinical effectiveness of subintimal angioplasty for chronic lower extremity arterial occlusive disease.
- To assess technical success, primary patency, limb salvage, and complication rates.
Main Methods:
- A meta-analysis of 14 studies involving 2350 patients with lower extremity arterial occlusive disease.
- Systematic review of electronic databases and cross-referencing for eligible studies.
- Data extraction and quality assessment by three independent reviewers.
Main Results:
- Technical success rates were 96.4% with re-entry catheters versus 87% without (P < 0.01).
- Limb salvage rates were 90.5% at 6 months and 81.5% at 12 months.
- Primary patency rates were 91% at 6 months with anti-platelet drugs versus 68.5% without (P < 0.01); overall complication rate was 8.25%.
Conclusions:
- Subintimal angioplasty is a safe and effective treatment for chronic lower extremity arterial occlusive disease.
- Selective use of re-entry devices and preoperative anti-platelet medication enhance procedural success.
- Further randomized trials and long-term follow-up are needed to confirm efficacy.
Objective:
To evaluate the clinical effectiveness of subintimal angioplasty in treating chronic arterial occlusive disease of lower extremity.
Methods:
Eligible studies concerning treatment by subintimal angioplasty in patients with arterial occlusive disease of lower extremity were identified from electronic database, cross-reference search and relative articles. The study quality and data extraction of all relevant articles were assessed by three independent reviewers. The study endpoints were technical success, primary patency, limb salvage, and complications.
Results:
A total of 352 studies were selected for comprehensive review. Fourteen studies including a total of 2350 patients matched the selection criteria. According to whether selective using of re-entry catheter were used or not, the technical success rates were 96.4% and 87% (P < 0.01). Limb salvage rate was 90.5% and 81.5% at 6 and 12 months respectively. Depending on whether preoperative use of anti-platelet drug, primary patency rate was 91% and 68.5% at 6 months respectively (P < 0.01). The complication rate was 8.25% without serious complications.
Conclusion:
This Meta-analysis suggests that subintimal angioplasty is a safe and effective method in treating chronic arterial occlusive disease of lower extremity with high technical success rate and limb salvage, and low serious complications. Selective using of re-entry devices and preoperative anti-platelet drug can improve the technical success rate and primary patency rate significantly. Despite the high rate of technical and clinical success of the procedure, randomized contrast trials and long-term follow-up results are required to confirm the efficacy of these results.
