Objective: The work aimed at describing an epidemioclinical, therapeutic\nand evolutionary characteristics of patients hospitalized for aortic dissection\nin the cardiology department in Point â??Gâ? Hospital University Center in Bamakoâ??\nMali. Methodology: It was a descriptive cross-sectional study from\nJanuary 2010 to February 2017 in the CHU Point G cardiology department,\nincluding all patients hospitalized during this period. Results: Of 6912 hospitalized\npatients, 23 patients were concerned by aortic dissection. The prevalence\nof aortic dissection was 0.33%. The most affected age group was 50 - 69\n(43.5%) of patients. The predominance was male with a sex ratio of 4.75. The\ncardiovascular risk factors were high blood pressure (73.9%) and smoking\n(60.9%). The major functional signs were chest pain (65.2%) and dyspnea\n(65.2%). Asphygmy (56.5%) and breath of aortic insufficiency (60.9%) were\nthe dominant physical signs. The electrocardiogram recorded sinus tachycardia\nwith 86.9% of patients. The radiographic of the frontal thorax showed\nmediastina widening (73.9%). At echocardiography, dilatation of the ascending\naorta was described with 73.9% and the intimal veil (47.8%). Pericardial\neffusion was observed with 26.1% of patients. In the thoracic angioscan, the aortic dissection gave 43.5% for type A and 56.5% for type B. The aneurysm\nof the aorta was abdominal with 21.7%, ascending portion (13.0%) and descending\nwith 8.7%. Complications were dominated by heart failure (47.8%)\nand aneurysm of the aorta (34.8%). The lethality was 52.2%. Conclusion:\nAortic dissection is a medical and surgical emergency with poor prediction.
