The onset of acute type A aortic dissection following recovery of type B intramural haematoma: a case report

BackgroundAortic intramural hematoma is a life-threatening condition reported with increasing frequency. It can be classified into Stanford type A or B depending on whether the ascending or descending aorta are involved, respectively. However, the onset of acute type A aortic dissection following recovery of type B intramural haematoma is rarely reported.Case presentationWe present an uncommon case of acute Stanford type A aortic dissection developing 3months after recovery of type B IMH in a 47-year-old female.She complained acute chest pain. The operation was successfully done. She was in good condition and asymptomatic at a 3-month follow-up.ConclusionsType B intramural haematoma can lead to type A aortic dissection even after totally absorbed and the primary entry has the potential to be located in the ascending aorta. Unsatisfied blood pressure control may be the underlying cause.
