METHOD OF SURGICAL TREATMENT OF ANEURYSM OF THORACOABDOMINAL PART OF AORTA Russian patent published in 2010 - IPC A61B17/00 A61F2/06 

FIELD: medicine.

SUBSTANCE: method relates to medicine, namely to cardio-vascular surgery and can be used in treatment of thoracoabdominal part of aorta. For this purpose determined are prevalence and degree of aorta and its branches affection, places of origin of aorta branches and their diametres. After that selection of necessary diametre and length of aorta prosthesis is performed. Prostheses of said arteries are sewn into wall of aorta prosthesis correspondingly to place of origin of artery feeding spinal marrow, celiac trunk, superior mesenteric artery, right and left renal arteries. After that bases of vessel prostheses are compressed, intravascular shunts are introduced into opening of prostheses of celiac trunk, superior mesenteric artery, right and left renal arteries and fixed with tourniquets. After that intra-arterial shunt is introduced into opening of distal end of aorta prosthesis and fixed with tourniquet. Aorta prosthesis is compressed, clamps are applied more proximally than aneurysm, aorta wall is cut longitudinally between clamps, and intra-aortal stunt is introduced into its opening and fixed with tourniquets. Then clamps are removed from aorta, proximal end of aorta prosthesis is sewn to aorta cut, proximal tourniquet is released. After that aorta is compressed more distally than aneurysm, wall of aorta is cut with transversal cut, tip of intra-arterial shunt is introduced into opening and fixed with tourniquet. Sewing of aorta edge and aorta prosthesis at a distance from each other with separate sutures is performed, aorta prosthesis is compressed, tourniquets are released and intra-arterial stunt is removed. Sutures are tightened and tied, clamp is removed, distal tourniquet with intra-aortal shunt is released and moved to aneurysm cavity. Aorta is compressed more proximally than eneurysm, aneurysm wall is cut along its all length, intra-aorta shunt is removed from aneurysm cavity. Tips of intra-vascular shunts are introduced into orifices of celiac trunk, superior mesenteric artery, right and left renal arteries. Clamps from prostheses bases are removed, artery prosthesis is sewn to its orifice, prosthesis edge and orifices of arteries are sewn at a distance from each other. Prosthesis is compressed, tourniquet is released, intravascular shunts are removed, sutures are tightened and tied.

EFFECT: method allows to prevent dissection and rupture of aorta wall with reduction of time of aorta compression.
