Maladie de Takayasu révélée par une fuite aortique massive associée à un anévrisme de l’aorte ascendante (À propos de deux cas opérés)

Abstract

Aortic regurgitation caused by non-specific aortitis is relatively rare, and is now considered as an important risk factor related to mortality. Aortic valve replacement surgery is the only curative treatment. Aneurismal dilatation of the ascending thoracic aorta associated with aortic regurgitation is a rare involvement in Takayasu, there are many difficult problems in surgical treatment of this lesion, because of its inflammatory nature, so steroid therapy before and after surgery is therefore vital. We report the cases of tow young Moroccans women (32–35 years-old) with an ascending aortic aneurism associated to aortic insufficiency. The subsequent evaluation of the entire aorta, demonstrated the presence of multiple steno-occlusive lesions. Aortic valve replacement was performed associated with graft replacement of the ascending aorta without coronary artery reimplantation. Histopathological examination of the ascending aorta and aortic valve, showed findings in favour Takayasu’s arteritis.
