intimectomy

Full Definition

Intimectomy is a surgical technique involving the controlled removal of the thickened or diseased intimal layer from the arterial wall to restore adequate luminal diameter and blood flow. This procedure is often performed during bypass surgery or as part of endarterectomy when the intimal disease is too extensive for simple removal. The technique requires careful dissection to avoid perforation while ensuring complete removal of obstructive material.

Usage

Usage note: Distinguish from endarterectomy, which removes intima and media layers together.
