ABSTRACT
Abstract Background and objectives: The aneurysm in the pulmonary trunk is a rare disease. Because of its location, a rupture can lead to right ventricular failure and sudden death. Aneurysmorraphy is the most widely used surgical treatment in these cases. The aim of this study is to report a successful balanced general anesthesia for aneurysmorraphy of pulmonary trunk. Case report: Male patient, 28 years, asymptomatic, diagnosed with an aneurysm in the pulmonary trunk. According to the location of the aneurysm and the consequent failure of the pulmonary valve, an aneurysmorraphy was indicated, with implantation of vascular-valvular prosthesis (valved tube). We opted for a balanced general anesthesia, seeking to prevent an increase in systemic and pulmonary vascular resistances, thus avoiding to cause stress on the wall of the aneurysmal vessel. Conclusions: A balanced general anesthesia, in combination with adequate ventilation to prevent elevation in pulmonary vascular pressure, was appropriate for surgical repair of an aneurysm in the pulmonary trunk.
Resumo Justificativa e objetivos: O aneurisma de tronco de artéria pulmonar é uma doença rara. Por sua localização, uma ruptura pode conduzir à falência do ventrículo direito e à morte súbita. A aneurismorrafia é o tratamento cirúrgico mais usado nesses casos. O objetivo foi relatar uma anestesia geral balanceada para aneurismorrafia de tronco de artéria pulmonar feita com sucesso. Relato do caso: Paciente do sexo masculino, 28 anos, assintomático, diagnosticado com aneurisma de tronco de artéria pulmonar. De acordo com a localização do aneurisma e a consequente insuficiência da válvula pulmonar, foi indicada a aneurismorrafia com implante de prótese vascular e valvular (tubo valvado). Optou-se pela anestesia geral balanceada, para impedir um aumento nas resistências vasculares sistêmicas e pulmonar e evitar-se, dessa maneira, um estresse sobre a parede do vaso aneurismático. Conclusões: A anestesia geral balanceada, em associação com uma ventilação adequada para evitar elevação na pressão vascular pulmonar, foi apropriada para correção cirúrgica de um aneurisma em tronco pulmonar.

Los aneurismas de la arteria innominada son una entidad poco frecuente. Los mecanismos patogénicos son variados y los pacientes suelen cursar asintomáticos, aunque pueden presentar diversos cuadros clínicos. El tratamiento quirúrgico depende de las características anatómicas y debe realizarse para prevenir las complicaciones. Se describe el caso de un hombre de 77 años de edad con angina inestable por aterosclerosis coronaria y enfermedad multivascular, en quien incidentalmente durante una revascularización miocárdica se encontró un aneurisma sacular con un diámetro de 2 cm en el origen de la arteria innominada. Después de la revascularización, una vez fuera de la derivación cardiopulmonar y en el mismo tiempo quirúrgico, se realizó aneurismorrafia sin complicaciones, con resultados satisfactorios y sin secuelas neurológicas.
Innominate artery aneurysms are an uncommon pathology. There are several pathogenic mechanisms involved in their formation, and patients are usually asymptomatic. However, different clinical presentations are possible. Management varies according to anatomic characteristics. Surgical treatment is recommended in order to avoid complications. We present a case of a patient with an innominate artery aneurysm found incidentally during surgery for myocardial revascularization. A 77-year-old male with unstable angina secondary to multivascular ischemic heart disease was subjected to surgery. Coronary angiography did not evaluate the aortic arch and its branches. During the surgical procedure we found a 2-cm saccular aneurysm at the origin of the innominate artery. After completing the revascularization procedure and once the patient was no longer on cardiopulmonary bypass, aneurysmorrhaphy was successfully done.
