Sano Modification
Pronunciation: SAH-no
A surgical technique used in the Norwood procedure where a right ventricle-to-pulmonary artery conduit is created instead of a Blalock-Taussig shunt.
Full Definition
The Sano modification is a variation of the first-stage Norwood procedure for hypoplastic left heart syndrome. Instead of creating a systemic-to-pulmonary artery shunt, a conduit is placed from the right ventricle to the pulmonary artery. This modification aims to provide more stable pulmonary blood flow and reduce the volume load on the single right ventricle, potentially improving outcomes before the next stage of palliation.
Usage
Usage note: Named after Shunji Sano who developed this technique. Often written with capital 'S' as it's an eponym.
In Context
