To repair many types of single ventricle heart defects, including hypoplastic left heart syndrome (HLHS), tricuspid atresia, double outlet left ventricle (DOLV), some heterotaxy defects, and other congenital heart defects, surgeons often perform a series of open heart procedures. The bidirectional Glenn shunt or hemi-Fontan procedure is one of several surgical technique used to temporarily improve cardiac function in patients with severe.
During staged reconstruction, surgeons perform a series of procedures over several years, including the Norwood procedure, Glenn operation, and Fontan. Diagram depicting a bidirectional Glenn shunt.
The superior vena cava (SVC) is removed from the heart and connected end-to-side to the right pulmonary artery. The bidirectional Glenn procedure is the surgery used to prepare the heart for a Fontan procedure.
It is a surgery in which a detour (shunt) is created from the.Blalock, Glenn & Fontan Procedures. There are several different procedures that are used in the treatment of cardiac defects. Below are basic details for the most common ones which people with Down's Syndrome have done, but they are often modified to deal with the individual aspects of a patient's condition. Blalock-Taussig (BT) shunt.
Background The bidirectional Glenn (BDG) is frequently used in the staged surgical management of single ventricle patients. Controversy exists whether accessory pulmonary blood flow (APBF) sources should be left at the time of the BDG to augment systemic saturation or should be eliminated to reduce volume load of the ventricle.
The present study was a retrospective review to assess the. At age months, infants with these conditions (including both those who have had a shunt and those who have not) will generally undergo an operation called bidirectional Glenn or BDG for short.
In this operation, we connect a large vein called the superior vena cava to the pulmonary arteries. The Sano Modification of the Norwood (diagram at right) involves the placement of a conduit (light blue) between the pulmonary artery and the right ventricle instead of the Modified Blalock-Taussig Shunt. Hypoplastic left heart is in the spectrum of single ventricle defects that has a sequence of staged repairs.
Jul 17, · In this configuration, the Glenn Shunt only sends blood to the right lung. Here’s a good diagram of the Classic Glenn Shunt and here’s what I think is an even better drawing. The second link contains links to important information about both versions of the Glenn, worth your time to read.BiDirectional Glenn OperationGlenn shunt procedure and bidirectional Glenn shunt surgery - Remedy Land
