2016年1月14日 · 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.

The Waterston shunt has gained considerable popularity in the treatment of infants with severe cyanotic congenital heart dis- ease with decreased pulmonary blood flow, particularly in in- fants under 6 months of age with hypoplastic pulmonary arteries.

Two hundred twenty-seven patients (median age 5.4 months) in whom a Waterston anastomosis was done for initial palliation of tetralogy of Fallot between 1966 and 1979 were studied. Twelve patients died in the hospital (5.3%; 70% confidence limits, 3.8% to 7.3%).

• Waterston-Cooley shunt. Anastomosis between the ascending aorta and the right PA. Rarely used currently. • Potts shunt. Anastomosis between the descending aorta and the left PA. Rarely used but has been recently applied to patients with refractory pulmonary hypertension to decompress the pulmonary circulation.

Waterston. In order to have a more uniform surgical technique, the Waterston shunts were performed by one of the two surgeons, while the Cooley type was done by the other. There were 48 patients with tetralogy of Fallot, 9 with pulmonary atresia, 11 with transposition of the great vessels and pulmonary

2008年11月2日 · Waterston shunt is one of the older central aortopulmonary shunts connecting ascending aorta to right pulmonary artery. Central shunts have a higher chance of producing pulmonary hypertension later. Potts shunt connects the descending aorta to left pulmonary artery.

Wa·ter·ston shunt ( wă'tĕr-stŏn ), creation of a narrow opening (about 3 mm) between the ascending aorta and the subjacent right pulmonary artery to increase pulmonary circulation in cyanotic heart disease with decreased pulmonary flow.

2016年3月15日 · The original (classic) Blalock–Taussig (BT) shunt (described in 1945) involved ligation and division of the left subclavian artery and an end-to-side anastomosis of the proximal left subclavian artery to the pulmonary artery.

pulmonary artery shunt has become the palliative procedure of choice in the first six months of life for infants with cyanotic heart and reduced pulmonary flow.

2020年4月12日 · Waterston shunt ( Fig. 2.2): The Waterston shunt is an artificial connection between the ascending aorta and the right pulmonary artery. It is inserted into both vessels via partial unclamping within the scope of a right thoracotomy.
