fasciotomy
Surgical division of fascial compartments to relieve pressure and restore circulation.
Full Definition
Fasciotomy is the surgical incision of fascial planes to decompress elevated compartment pressures and restore normal circulation to at-risk tissues. This procedure is the definitive treatment for compartment syndrome and must be performed emergently to prevent irreversible tissue necrosis. The technique involves making strategic skin and fascial incisions to release all affected compartments while preserving neurovascular structures. In the leg, this typically requires both medial and lateral incisions to decompress all four compartments. Post-fasciotomy management includes wound care, potential skin grafting for coverage of fascial defects, and monitoring for complications such as infection or persistent ischemia. Delayed closure or coverage procedures may be required once swelling subsides and tissue viability is confirmed.
Usage
Usage note: Distinct from fasciectomy, which involves removal of fascial tissue rather than simple incision.
