Tratamiento quirúrgico de aneurisma aórtico por la técnica de Bentall-Bono, a propósito de un caso clínico

Abstract

An aortic aneurysm is a protrusion or dilation that deforms the artery and leads it to exceed its own diameter by more than 50%, this dilation can be triggered due to different risk factors, which are usually dependent or independent of the patient, such as age , gender, patient size and pathological arterial segment. This excess arterial diameter results from a progressive weakening of the mural layers, mostly of the intima and media, which in the short or long term will generate the retention of a perivascular clot in the adventitia of the vessel. Aneurysms of the ascending aorta are characterized by their slow and silent growth, which does not generate florid symptoms but rather debuts with aortic coarctation that most of the time ends in the death of the patient. We present the case of a 50-year-old patient, with no significant pathological history and no obvious risk factors, who is identified on physical examination as hypotensive, afebrile, conscious, oriented in space and person, and a diastolic murmur is heard in the aortic focus. 6/6 irradiated to accessory aortic focus, external hairpin, evident Quincke's signs, Traube, Musset, Hill, celerity pulse and Corrigan's present. It is decided to perform an echocardiogram, where a quadricuspid aortic valve is identified, so it is decided to perform a chest tomography where the diagnosis of an ascending aortic aneurysm is corroborated. He was referred to a more complex hospital, where it was decided to apply the Bental-Bono technique to resolve the aneurysm.
