Abstract:
Purpose To evaluate the abdominal aortic remodeling in both morphology and hemodynamic changes before and after thoracic endovascular aortic repair (TEVAR) for aortic dissection (AD) of DeBakey type Ⅲ by using color Doppler ultrasound and contrast-enhanced ultrasound,in order to provide a novel imaging method for clinical treatment in addition to aortic computed tomography angiography (CTA).Materials and Methods Thirty patients with complicate AD of Debakey type Ⅲ were recruited.The abdominal vessels of patients were examined by color Doppler and contrast-enhanced ultrasound at different times including before TEVAR operation,and 1 day,1 month after operation.The size of true and false lumen,hemodynamic characteristics,thrombosis in false lumen,distal tear sites and blood supply of vital organs were analyzed combined with CTA results.Results The diameter and maximal blood flow velocity of true lumen at abdominal aorta 1 day,1 month after operation were significantly increased compared with those before operation (P＜0.05),but the diameter and maximal velocity of false lumen after operation were significantly decreased compared with those before operation (P＜0.05).The blood supply of affected organs had no significant difference before and after operation (all P＞0.05).The vessel diameter measurements were similar to those of CTA (P＞0.05).Conclusion Color Doppler imaging combined with contrast-enhanced ultrasound is a simple,reproducible method to evaluate the vascular remodeling in hemodynamics and morphology after TEVAR for complicate AD of DeBakey type Ⅲ,which can overcome the shortage of previous assessment only in morphology.
