Damus-Kaye-Stansel procedure
Pronunciation: DAY-mus KAY STAN-sel
Also written as: DKS — Damus-Kaye-Stansel procedure
Surgical procedure that creates a direct connection between the pulmonary artery and ascending aorta, typically performed for complex single ventricle physiology.
Full Definition
The Damus-Kaye-Stansel (DKS) procedure is a palliative surgical technique used in complex congenital heart disease, particularly in patients with single ventricle physiology and systemic outflow obstruction. The procedure involves creating an anastomosis between the main pulmonary artery and the ascending aorta, effectively allowing the single ventricle to pump blood to both the systemic and pulmonary circulations. This is often performed as part of a staged approach toward Fontan completion. The native aortic arch is typically ligated or oversewn, and pulmonary blood flow is maintained through a systemic-to-pulmonary artery shunt. The procedure helps optimize cardiac output while reducing volume overload on the single ventricle.
Usage
Usage note: Often abbreviated as DKS in clinical notes; ensure clarity when discussing alongside other complex procedures.
