Introduction
The classical treatment of type B aortic dissection is based on either medical treatment for uncomplicated aortic dissection or open surgery. Now with improvements in endovascular intervention, it seems to be more effective, safe, and with favorable effects on aortic remodeling.
Patients and methods
This is a retrospective study that aimed to evaluate the effect of thoracic endovascular repair (TEVAR) on remodeling in uncomplicated acute type B aortic dissection. Serial contrast-enhanced computed tomography scans of 32 patients with acute type B aortic dissection were performed and the data were collected between March 2018 and October 2018. Thirteen patients received best medical therapy only and 19 patients received best medical therapy and TEVAR, and the effect of TEVAR on aortic remodeling was compared by a computed tomography scan.
Results
Data of 32 patients (20 men and 12 women) with a median age of 59 years were collected; the median follow-up period was 6 months. TEVAR resulted in an increase in the true lumen diameter (from 2.0085 to 3.039 cm) and a decrease in the false lumen diameter (from 1.8767 to 0.785 cm). However, in the medical group only, the diameters remained almost unchanged (true lumen diameter ranged from 1.9024 to 2.3898 cm and false lumen diameter ranged from 1.9045 to 1.7245 cm).
Conclusion
TEVAR for acute type B aortic dissection resulted in a significant increase in the true lumen diameter and decrease in the false lumen diameter.
