Spontaneous resolution late after aortic dissection.
A 50-year-old man was operated on for acute type I (DeBakey classification) aortic dissection. The supracoronary ascending aorta was replaced with an interposition graft. Postoperative computed tomography and angiography clearly revealed a double-barrelled aortic arch, left common carotid artery and descending thoracoabdominal aorta with contrast filling of both true and false lumen starting from the distal anastomosis. The same finding was noted at 1 year follow-up with severe compression of the true lumen by the false lumen. At this time, anticoagulation therapy was stopped. One year later, computed tomography showed spontaneous resolution of the dissection in the aortic arch, left common carotid artery and descending aorta over its full length. This was confirmed by angiography. This case reports illustrates that spontaneous resolution of a dissected descending aorta can occur late after surgery from type 1 dissection, but it remains very rare.
