METHOD FOR PROSTHESIS OF DESCENDING SEGMENT OF THORACIC AORTA Russian patent published in 2019 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly to cardiovascular surgery. Aorta is separated from all sides immediately distal to left subclavian artery. Aorta is separated from all sides, at least 10 mm distal from the aneurysm. Two atraumatic clamps with a step of at least 10 mm are used to clamp a segment of aorta separated immediately from the distal left subclavian artery. Atraumatic clamp is used to clamp an isolated distal aneurysm of the aortic segment. Between two clamps, a segment of the aorta isolated immediately distal to the left subclavian artery is stopped. Aortic aneurism is dissected longitudinally along its anterior wall. Content of aortic aneurysm is removed. Performing partial excision of those parts of anterior and lateral walls of aneurysm, which do not contain the aorta branches. Monofilament suture of 1/0 or 2/0 or 3/0 on a needle with a size of not less than 26 is closed with an aneurismatic sac with a continuous blanket suture without a posterior wall retention containing branches of a descending segment of a thoracic aorta. Blood flow is preserved along all branches of the aorta of the closed aneurysmal sac so that an aneurism is reduced and haemostasis is achieved. That is followed by prosthetics of the descending segment of the thoracic aorta, for which distal and proximal anastomoses are formed between the linear prosthesis and aorta.

EFFECT: method enables preserving the functioning of all the arteries involved in the spinal blood supply, minimizing the risk of developing disabling complications such as spinal cord necrosis.
