Glenn procedure
Glenn procedure
The Glenn procedure (pronunciation: /ɡlɛn/), also known as the bidirectional Glenn procedure or hemi-Fontan procedure, is a type of heart surgery used to treat certain types of congenital heart defects.
Etymology
The procedure is named after American surgeon Dr. William W. L. Glenn, who first performed the operation in the 1950s.
Procedure
In the Glenn procedure, the superior vena cava (SVC) is disconnected from the heart and reconnected to the pulmonary artery. This allows oxygen-poor blood to bypass the heart and flow directly to the lungs, reducing the workload on the heart and improving oxygenation of the blood.
Indications
The Glenn procedure is typically performed as part of a series of surgeries to treat complex congenital heart defects, such as hypoplastic left heart syndrome (HLHS) and tricuspid atresia. It is usually performed after a Norwood procedure and before a Fontan procedure.
Risks and Complications
As with any major surgery, the Glenn procedure carries risks, including bleeding, infection, arrhythmia, and heart failure. Long-term complications may include protein-losing enteropathy and plastic bronchitis.
