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.
