Congenital Saccular Aneurysm of Coarctation of Aorta: A Case Report

True saccular aneurysm is exceptional in coarctation of aorta in children. a 6-year-old girl with headache and systemic arterial hypertension referred to our center for cardiovascular evaluation. physical examination revealed high blood pressure and weak lower extremity pulses. two-dimensional and doppler echocardiography and angiography demonstrated a saccular aneurysm of the descending aorta, 5×4 cm in size, associated with aortic coarctation. aneurysmectomy was performed without cardiopulmonary bypass. the section of the aorta containing the coarctation and the aneurysm was resected and replaced with a 15-mm woven polyester graft. histological examination revealed a thin walled aneurysm with hyalinosis changes and decreased elastic fibers. one-year echocardiographic follow-up revealed no gradient across of dacron tube and hypertension decreased to normal level.
