Summary
New endovascular instruments destroy atheromatous plaques and recalibrate arteries, expanding angioplasty limits for previously inaccessible stenoses and acute occlusions. However, these advanced techniques do not yet prevent restenosis.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Context:
- Endovascular procedures have advanced with new instruments for plaque destruction and arterial recalibration.
- These innovations aim to treat complex vascular conditions previously considered inaccessible.
Purpose:
- To review novel endovascular instruments for plaque destruction (atherectomy) and arterial recalibration (stents, heating balloons).
- To assess the expanded therapeutic limits and treatment of acute occlusions offered by these new techniques.
Summary:
- Directional and rotational atherectomy devices (e.g., Simpson's Atherocath, Rotablator, TEC) pulverize or extract atheromatous plaques.
- Vascular recalibration is achieved using various stents (e.g., Medivent, Palmaz Schatz, Wiktor) or heating balloons, often requiring anticoagulant therapy.
- Specialized tools like Kaltenbach's rotating guide aid in traversing complete occlusions, typically followed by conventional angioplasty.
Impact:
- These techniques broaden the scope of angioplasty, enabling treatment of previously inaccessible stenoses and acute occlusions.
- Despite advancements, current endovascular methods have not demonstrated efficacy in preventing restenosis.
