Systemic-to-Pulmonary Shunt
A surgical connection that diverts oxygenated blood from the systemic circulation to the pulmonary arteries to increase pulmonary blood flow.
Full Definition
A systemic-to-pulmonary shunt is a palliative surgical procedure that creates an artificial connection between the systemic arterial circulation and the pulmonary arteries. These shunts are designed to increase pulmonary blood flow in conditions with decreased pulmonary circulation, such as pulmonary atresia or severe tetralogy of Fallot. Common types include the Blalock-Taussig shunt and central shunts. The procedure provides temporary improvement in oxygenation while preserving options for future definitive repair. Editorial consistency requires proper hyphenation and directional clarity.
Usage
Usage note: Always hyphenate and maintain directional clarity from systemic to pulmonary circulation.
