Sano modification
Pronunciation: SAH-no
Right ventricle to pulmonary artery conduit used in Norwood stage 1 as alternative to BT shunt.
Full Definition
The Sano modification refers to the use of a right ventricle to pulmonary artery conduit during the Norwood stage 1 procedure instead of a Blalock-Taussig shunt for pulmonary blood flow. Developed by Shunji Sano, this technique places a small conduit from the right ventricle to the main pulmonary artery, potentially providing more stable pulmonary blood flow and better diastolic pressures. The choice between Sano modification and BT shunt remains debated, with institutional preferences varying.
Usage
Usage note: Specify type of conduit (RV-PA) when editing to avoid confusion with other shunt types.
