METHOD FOR SINGLE-STAGE FULL THORACIC AORTIC REPLACEMENT Russian patent published in 2021 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiovascular surgery. The common femoral artery is consequently cannulated. An additional arterial cannula is installed in the branch of the multi-branch prosthesis of the aortic arch, the right atrial appendage, transition to the artificial circulation is executed according to the following plan: the right atrium - the additional branch of the multi-branch prosthesis of the aortic arch - the common femoral artery. Perfusion through the arterial cannulas is therein executed separately using two pumps. Anastomoses of the brachiocephalic trunk, the left common carotid artery and the left subclavian artery with branches of the multi-branch prosthesis of the aortic arch are gradually tied at the entrance, applying clamps, transected and formed. Cardioplegia is performed. The apex of the heart is moved into the wound. Longitudinal pericardiotomy is performed along the posterior wall. A section of the descending thoracic aorta above the diaphragm is isolated. The aorta is clamped and transected. An anastomosis of the distal aorta is formed with a tubular prosthesis of the descending aorta. The left pleural cavity is opened parallel to and below the sternum. A tubular prosthesis of the descending aorta is directed in the left pleural cavity behind the lung and the descending thoracic aorta. An anastomosis is formed between the multi-branch prosthesis of the aortic arch and the prosthesis of the descending aorta. The ascending aorta is replaced. An anastomosis is formed between the ascending aortic prosthesis and the multi-branch prosthesis of the aortic arch. The aneurysm of the ascending aorta is excised. The aneurysmally altered arch and the descending thoracic aorta are sutured with a monofilament thread without capturing the posterior wall containing the branches of the arch and the descending thoracic aorta, while maintaining the blood flow in all aortal branches of the sutured aneurysmal sac, without deep hypothermia and stagnation of circulation.

EFFECT: method allows fully replacing the thoracic aorta in a single stage while reducing the risk of developing complications and minimising injuries.
