Resolution of Ascending Aortic Dissection in a Stanford Type A Patient

The Diagnosis of Spontaneous Coronary Artery Dissection by Optical Coherence Tomography

“…The exact mechanism underlying the spontaneous resolution of SCAD is unknown and has not been explained in the literature. It has been hypothesized that thrombus formation in the false lumen occludes the false lumen and causes fibrosis between the two dissected layers in cases with aortic dissection ( 7 ). It is presumed that the intramural hematoma found in the false lumen is gradually absorbed due to some unknown mechanism, and that finally, the inner membrane and media are reorganized with the restoration of the normal three-layer structure of blood vessels.…”

Conservatively treated Type B intramural hematoma: Progression into acute aortic dissection followed by spontaneous resolution, assessed by CT

“…The natural evolution of conservatively treated descending aorta dissection may have a favourable course with possible false-lumen thrombosis, although it may also be complicated by aneurismal formation or progression of the dissection ( 7 , 10 ). However, a complete spontaneous resolution of the aortic dissection has rarely been reported ( 5 , 6 ). Moreover, to our knowledge, the full spectrum of IMH progression into dissection followed by resolution has not been demonstrated previously.…”

“…Currently, cases of acute type B IMH (not involving the ascending aorta) are usually treated conservatively; however, progressive disease, including aortic dissection, has been described ( 1 , 2 , 3 , 4 ). Acute type B aortic dissections are also treated conservatively with antihypertensive medication, and a favorable course with false lumen-size reduction or thrombosis is frequent; however, a complete resolution of the aortic dissection has rarely been reported ( 5 , 6 ).…”
