**Atherectomy** is a minimally invasive medical procedure used to remove plaque ( fatty deposits, calcium, or fibrous tissue ) from inside an artery. It is typically performed to treat **peripheral artery disease ( PAD ) ** in the legs, though it can also be used in coronary ( heart ) arteries.

Here’s a simple breakdown:
- **How it works:** A thin, flexible tube ( catheter ) with a specialized cutting, shaving, rotating, or laser tip is threaded through the artery to the blockage. The device then shaves, grinds, or vaporizes the plaque into tiny particles that the body naturally clears away.
- **Purpose:** Unlike a standard angioplasty ( which just compresses plaque with a balloon ) , atherectomy actually *removes* the plaque. This is especially useful for:
- **Hard, calcified plaque** that a balloon cannot easily compress.
- Blockages in certain locations ( e. g. , near joints where stents might fracture ) .
- **Types of atherectomy devices:**
- **Rotational ( Rotablator ) :** Uses a high - speed, diamond - coated burr to grind plaque into microscopic dust.
- **Directional:** Has a window and a cutter to shave off and capture plaque in a nose cone.
- **Orbital:** An elliptical, sandpaper - like crown that sands away plaque while preserving healthy artery wall.
- **Laser:** Uses ultraviolet light pulses to vaporize plaque.
- **What to expect:** Performed under local anesthesia ( awake but numbed ) or sedation. You may go home the same day or stay overnight. Recovery is faster than bypass surgery.
- **Risks:** Include artery injury, bleeding, infection, or ( rarely ) embolism ( plaque particles blocking a smaller vessel downstream ) .
In short: atherectomy is a “roto - rooter” for arteries—it drills or shaves away stubborn plaque when balloons or stents alone are insufficient. Your doctor would recommend it based on the type and location of your blockage.
آترکتومی روشی برای برداشتن پلاک از شریان ( رگ خونی ) است. از بین بردن پلاک باعث بازتر شدن شریان می شود، بنابراین خون می تواند آزادانه تر به قلب جریان یابد.
