Atherectomy: Symptoms, Classification, Diagnosis & Recovery

Atherectomy is a minimally invasive procedure healthcare providers use to eliminate plaque buildup and widen narrowed or blocked arteries. This intervention aims to restore normal blood flow and alleviate symptoms associated with peripheral artery disease (PAD).

Using a catheter equipped with small rotating blades or a laser, plaque is shaved or vaporized away during this minimally invasive intervention. Surgical atherectomy may be considered for patients with particularly hardened plaque or those with persistent plaque constriction following angioplasty and stent placement.

The following are various types of techniques used in atherectomy procedures to remove plaque from arteries:

• Excisional Atherectomy: Utilizes a blade to cut plaque in a single direction.
• Laser Ablation Atherectomy: Involves using a laser to disintegrate plaque.
• Orbital Atherectomy: A spinning tool acts akin to sandpaper, eliminating plaque.
• Rotational Atherectomy: Small blades cut plaque in a circular motion.

Before performing an atherectomy, doctors providers assess for signs and symptoms associated with narrowed or blocked arteries, which may include:

• Intermittent Claudication
• Decreased Blood Flow
• Weak Pulse
• Skin Changes
• Erectile Dysfunction
• Non-Healing Wounds
• Other Cardiovascular Symptoms
