Glenn
Glenn
Glenn (pronounced /ɡlɛn/) is a term used in the medical field, specifically in cardiology, to refer to a type of surgical procedure known as the Glenn procedure. The term is derived from the name of the surgeon, Dr. William W. L. Glenn, who first performed the procedure in the mid-20th century.
Definition
The Glenn procedure, also known as the Glenn shunt or Glenn operation, is a type of heart surgery performed on patients with certain types of congenital heart defects. It is typically performed as part of a series of surgeries to treat conditions such as hypoplastic left heart syndrome or tricuspid atresia.
Procedure
In the Glenn procedure, the superior vena cava (SVC) is disconnected from the right atrium and is instead connected to the pulmonary artery. This allows blood from the upper body to flow directly to the lungs, bypassing the heart. This is done to improve oxygenation of the blood in patients with certain types of heart defects.
Related Terms
- Fontan procedure: A surgical procedure often performed after the Glenn procedure, which connects the inferior vena cava to the pulmonary artery.
- Bidirectional Glenn procedure: A modification of the original Glenn procedure, where the SVC is connected to both the right and left branches of the pulmonary artery.
- Cyanotic heart disease: A type of congenital heart defect that can be treated with the Glenn procedure.
