Summary
Subintimal angioplasty (SIA) is a safe and effective endovascular technique for treating lower limb arterial occlusions. It creates a new lumen, offering an alternative to surgery for complex cases and high-risk patients.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Background:
- Subintimal angioplasty (SIA) has been utilized since 1990 for symptomatic lower limb arterial occlusions.
- It involves creating a dissection in the subintimal plane to bypass occluded segments.
- The technique re-enters the true lumen distally, creating a new extraluminal channel free of plaque.
Purpose of the Study:
- To review the indications, techniques, outcomes, and complications of subintimal angioplasty.
- To highlight SIA's role in managing complex infrapopliteal occlusions.
- To discuss its advantages over traditional methods for limb-threatening ischemia.
Main Methods:
- Review of existing literature on subintimal angioplasty.
- Analysis of procedural variations and technical developments.
- Evaluation of outcomes, patency rates, and associated complications.
Main Results:
- SIA is a safe and effective procedure for lower limb arterial occlusions.
- It offers advantages over intraluminal angioplasty and open surgery.
- The technique is suitable for complex occlusions and high-risk patients, with good primary success and long-term outcomes.
Conclusions:
- Subintimal angioplasty represents a paradigm shift in managing lower limb ischemia.
- It expands endovascular treatment options for complex arterial disease.
- SIA does not preclude future surgical interventions and is increasingly adopted as first-line therapy.
