The bidirectional Glenn (BDG) shunt, or bidirectional cavopulmonary anastomosis, is a surgical technique used in pediatric cardiac surgery procedure used to temporarily improve blood oxygenation for patients with a congenital cardiac defect resulting in a single functional ventricle.
Coronal CT image in a 19-year-old patient with tricuspid atresia treated with bidirectional Glenn shunt and Fontan. The Fontan-Kreutzer procedure is the third procedure in the staged surgical palliation. [8] It is performed in children born with congenital heart disease without two functional ventricles and an effective parallel blood flow ...
Superior Cavopulmonary Bypass (Bidirectional Glenn or Hemi-Fontan Procedure), Total Cavopulmonary Bypass (Fontan Completion Procedure). The purpose of these operations is to redirect the blood flow of the deoxygenated blood to the lungs by attaching the Vena Cava directly to the Pulmonary Artery causing the blood that flows into the lungs to be ...
Glenn procedure is a palliative surgical procedure performed for patients with Tricuspid atresia. It is also part of the surgical treatment path for hypoplastic left heart syndrome and hypoplastic right heart syndrome. [1] [2] [3] This procedure has been largely replaced by Bidirectional Glenn procedure. [citation needed]
The second stage—the bidirectional Glenn or Hemi-Fontan (see also Kawashima procedure)—relieves some of the problems introduced by Stage I palliation. [33] In this operation, the superior vena cava is ligated from the heart and connected to the pulmonary circulation. At this time, the Blalock-Taussig or Sano shunt is taken down.
Technically it is very similar to the bidirectional Glenn procedure used to direct half the body's venous blood flow into the lungs. However, in patients with interrupted IVC, most of the blood from the lower body actually joins the blood from the upper body before returning to the heart via the superior vena cava (SVC).
A procedure like this could have lifelong consequences, depending on how much of the bowel needs to be surgically removed. After this type of surgery, some patients can’t tolerate a normal ...
Minimally invasive direct coronary artery bypass surgery (MIDCAB) is a form of OPCAB that involves an incision rather than cutting into the sternum. [5] An advanced form of this is totally endoscopic coronary artery bypass surgery (TECAB) that uses robotic surgery. [6] Off-pump surgery can be more technically challenging.
