Bidirectional Glenn Shunt: Stage I Palliative Surgery
Based on the animal experimental study performed by Haller, Dogliotti et al. had made improvements on classical Glenn surgery, including transection of the superior vena cava, closure of its atrial end, and end-to-side anastomosis of its distal end to the right pulmonary artery. These improvements can ensure not only the continuity between pulmonary artery and the superior vena cava but blood flow to the bilateral pulmonary artery. Bidirectional Glenn shunt, hence its name, was widely used in clinic for the treatment of functional single ventricle as a better surgical method instead of classic Glenn shunt.
