AORTIC DISSECTION RETROSPECTIVE STUDY OF A SERIES OF 20 CASES

Aortic dissection is a very serious condition that must be recognized early and whose treatment is a medical and surgical emergency. Management involves multidisciplinary expertise. In our retrospective study, we report 20 cases of aortic dissection surgically treated at Department of Cardiovascular Surgery at the University Hospital Avicenne of Rabat between 2004 and 2019, we analyze the epidemiological, clinical, paraclinical and surgical techniques performed in order to know the advantage very serious condition and hope for a better support. The average age in our study was 55 years with a male predominance, the main risk factor is hypertension, which was present in 14 of our patients. The master of the symptom is chest pain that is a constant sign in all patients and review key diagnostic confirmation is CTA in the absence of TOE emergency. All dissections were type A surgically treated.The surgery was based primarily on the Bentall technique consisting in the replacement of the ascending aorta dissected and aortic valve prosthesis in a synthetic in 13 of cases, while 7 cases underwent a replacement of aorta dissected by a prosthetic tube Dacron extra coronary position. The average duration of CPB and aortic clamping were 160 +/-20 min and 120 +/- 20min respectively with the implementation of a femoral cannulation sometimes associated with cannulationbicarotidienne The intra-hospital mortality rate was 35%, 5 patients died following bleeding one patient died from biventricular dysfunction and one patient died from renal failure others showed a favorable trend with simple post-operative within our service.
