          Abstract

          Paciente de 39 anos, portador de hipertensão arterial não controlada, submetido a cirurgia para tratamento de dissecção aguda de aorta tipo I. Devido ao grande envolvimento do óstio coronário direito pela dissecção aórtica, optou-se pela ressecção da porção comprometida do vaso, com interposição de tubo não valvulado de Dacron na aorta ascendente, suspensão da valva aórtica e ligadura do óstio da artéria coronária direita. Como não havia presença de aterosclerose no ramo interventricular anterior e na artéria coronária direita, decidimos realizar um enxerto venoso entre as artérias. O enxerto intercoronário apresentou bom funcionamento e todo o território dependente da coronária direita manteve boa contratilidade. O paciente recebeu alta hospitalar em boas condições clínicas, com função rniocárdica preservada.

          Translated abstract

          A thirty nine-year-old patient presenting arterial hypertension was operated upon for type I acute aortic dissection. Due to important alterations in the ascendent aorta with involvement of the right coronary ostium, the surgical procedure included resection of the segment of aorta containing the intimal tear and replacement with a Dacron prosthesis, suspension of the aortic valve and ligadure of the right coronary ostium. Technical difficulties brought the necessity of a different approach for the myocardium revascularization. Instead of the traditional described procedures, an intercoronary venous graft was put between the anterior interventricular artery (branch of the left coronary artery) and the right coronary artery. The intercoronary graft presented a good flow since the begining, keeping a good myocardial contratility. Patient left the hospital in a good clinical condition, with preserved myocardial function. Intercoronary graft should be an efficient alternative for revascularization of a corohary artery involved by aortic dissections.
