arterial switch operation
Surgical correction of transposition of great arteries by switching arterial connections.
Full Definition
The arterial switch operation (ASO) is the preferred surgical treatment for transposition of the great arteries, typically performed in neonates within the first weeks of life. The procedure involves detaching and switching the aorta and pulmonary artery to their anatomically correct positions, with coronary artery reimplantation. Anesthetic management requires expertise in neonatal physiology, careful temperature regulation, and monitoring for coronary ischemia. The operation has largely replaced the atrial switch procedures due to superior long-term outcomes.
Usage
Usage note: Often abbreviated as ASO in clinical documentation.
