Cooley-Waterston Anastomosis

Cooley-Watson anastomosis is one of the most common surgical techniques for tissue reconstruction and is used in a variety of medical specialties, including liver and kidney surgery, cardiovascular surgery, thoracic surgery, and gynecologic surgery. This method was invented in 1878 by James P.W. Colley (Cowley) and John Hares Watson separately. This operation is the most effective method for treating terminal injuries of the hepatic venous trunk, providing 121 lives with a follow-up period of up to 3 years after surgery.

**Cooley-Waterston anastomosis (Kulianastomosis)** or Cooley-Waterstone anastomosis is a procedure for connecting blood vessels using the principle of grafting and endovascular surgery, intended for the treatment of arteriovenous defects. This method is named after the American surgeons Thomas Cooley and Thomas Waterston.

The use of the Culley-Woderston anastomosis is based on the idea of ​​a distal anastomosis, in which the ascending aorta is connected to the lateral branches of the pulmonary artery. The ascending aorta is given below the origin of the left subclavian artery, and the branches of the arteries form an anastomosis with each other. This procedure facilitates pulmonary blood flow and helps correct congenital heart disease. The method began to be used at the end of the 20th century, and since then it has become one of the most common methods of treating arterial and mixed arteriovenous heart defects. This is due to the fact that most of the lesions are characterized by unidirectional damage to the branches of the pulmonary artery of varying degrees of severity, especially pronounced in children, thus, these defects can only be radically treated surgically.
