What is a bilateral bidirectional Glenn?
The bidirectional Glenn procedure directs the blood flow from the upper body veins directly to the lungs rather than the heart pumping the blood to the lungs first. The bidirectional Glenn shunt redirects blood flow from the upper body veins and is often performed prior to having a Fontan procedure.
Why Glenn shunt is bidirectional?
The aim of the bidirectional Glenn shunt is to improve oxygenation and reduce the load on the single functioning ventricle while the patient is prepared for definitive surgical correction through separation of the pulmonary and systemic circuits.
What is Glenn shunt surgery?
Glenn shunt procedures involve the anastomosis of the superior vena cava to the right pulmonary artery to increase pulmonary blood flow in patients with cyanotic heart disease.
What is the Hemi Fontan procedure?
The hemi-Fontan procedure includes association of the superior vena(e) cava(e) (SVC) with the branch pulmonary arteries, augmentation of the central pulmonary arteries, occlusion of the inflow of the SVC into the right atrium, and elimination of other sources of pulmonary blood flow.
How long does Glenn procedure last?
The Glenn procedure requires open heart surgery and will take about three hours to complete. During that time your baby will be on a heart-lung machine to temporarily take over breathing and blood circulation.
Is the Glenn procedure open heart?
The Glenn procedure is a type of open-heart surgery Babies who need this surgery typically have it when they’re 4–6 months old.
How long does the Fontan procedure take?
How long does the Fontan procedure take? This surgical procedure usually takes about four hours to perform. There are not as many risks following this surgery as are seen with the Norwood procedure. The amount of time your child will need to be in the hospital is usually around 10 to 14 days.
What is Waterston shunt?
A Waterston shunt is a form of palliative surgery performed in patients with tetralogy of Fallot prior to the ability to repair the defect. It consists of a shunt formed between the ascending aorta and the right pulmonary artery.
What is left pulmonary artery?
The left pulmonary artery (LPA) is one of the branches of the pulmonary trunk, branching at the level of the transthoracic plane of Ludwig. It is shorter than the right pulmonary artery and represents a direct posterior continuation of the pulmonary trunk.
What are bidirectional Glenn and Hemi-Fontan?
The bidirectional Glenn (BDG) and hemi-Fontan are surgical techniques used to create superior cavopulmonary anastomosis, the second stage repair in Fontan completion. They are performed in patients with an anatomic or functional single ventricle.
What is the difference between Glenn shunt and Hemi Fontan shunt?
The bidirectional Glenn shunt is utilized by some surgeons preferentially; however, others use the hemi-Fontan in patients who require extensive pulmo- nary arterioplasty for pulmonary artery distortion, which has become increasingly common with the RV to PA shunt modification of the Stage I Norwood operation.
How is a bi-directional Glenn operation performed?
The preparation and conduct of cardiopulmonary bypass are the same as for the hemi-Fontan operation. Most often the bi-directional Glenn can be performed using continuous cardiopulmonary bypass, moderate hypothermia, and no cardioplegic arrest. First, the SVC to right atrium junction is over-sewn.
What is the difference between Hemi Fontan and cardiopulmonary bypass?
The preparation and conduct of cardiopulmonary bypass are the same as for the hemi-Fontan operation. Most often the bi-directional Glenn can be performed using continuous cardiopulmonary bypass, moderate hypothermia, and no cardioplegic arrest.
