title: Circumferential dissection with intimal intussusception: an unusual case of acute aortic type A dissection.
abstract: An unusual case of a type-A aortic dissection with complete circumferential dissection just above the aortic valve with intimointimal intussuseption just distal to the left subclavian artery partially obstructing the descending aorta is described. CT-scan and transesophageal echocardiography together with clinical suspicion led to the correct diagnosis. Intimointimal intussusception is an unusual type of aortic dissection in which a proximal circumferential tear causes dissection with intussusception of the torn intima downstream, which could cause confusion about the appropriate diagnosis ([1]). It is a very infrequent complication of aortic dissection with only a few cases reported in the literature ([2-6]). CT scan and transesophageal echocardiography are the most accurate diagnostic tools ([7-9]). We describe a patient with intimointimal intussusception, diagnosed by CT scan and transesophageal echocardiography.
