Abstract:
Objective To evaluate the safety and effectiveness of thoracic endovascular aortic repair (TEVAR) in treating Standford type B thoracic aortic dissection complicated by type A intramural hematoma.Methods From October 2015 to January 2017,a total of 3 patients with Standford type B thoracic aortic dissection complicated by type A intramural hematoma were admitted to authors' hospital to receive treatment.After admission,conservative treatment such as stabilizing blood pressure and heart rate,symptomatic medication,etc.were carried out for 14 days,then,TEVAR was performed.Results Successful TEVAR was accomplished in all 3 patients,no serious complications,such as reverse tear,occurred.One month after TEVAR,reexamination of total aortic CT angiography revealed that the rupture of dissection was completely closed with no internal leakage,the blood flow in the true lumen was obviously improved,the intramural hematoma was remarkably absorbed and faded away,and the wall thickness of ascending aorta returned to normal range.The clinical symptoms were greatly improved,no serious complications such as paraplegia or death occurred.Conclusion For the treatment of Standford type B thoracic aortic dissection complicated by type A intramural hematoma,TEVAR performed at 14 days after the onset of disease is safe and effective if the ascending aorta intima is intact and the clinical symptoms are relived after medication of lowering blood pressure and heart rate.
