Experience with thoracic endovascular aortic repair applied in treating Stanford type B aortic dissection: An analysis of 98 cases.

BACKGROUND

Thoracic endovascular aortic repair (TEVAR) has been frequently applied in Stanford type B aortic dissection since thoracic aortic diseases were first treated with artificial vessels.

OBJECTIVES

The aim of this study was to analyze the clinical value of TEVAR applied in treating Stanford type B aortic dissection.

MATERIAL AND

METHODS

Between January 2007 and April 2014, 167 consecutive Stanford type B aortic dissection patients were treated with TEVAR and retrospectively analyzed.

RESULTS

All patients had a successful operation. A total of 98 patients were followed-up and the duration of the follow-up ranged from 3 to 63 months with a mean of 25.6 ±8.4 months. Proximal type I endoleak occurred in 18 patients with an incidence rate of 18.37% and a cuff was deployed in 7 patients, in whom the endoleak disappeared after 3 months. Two patients died in the perioperative period: one died from aortic dissection rupture, while the other died from infectious shock. One patient died from acute myocardial infarction during the follow-up period. Tears occurred in the end piece of stent grafts in 12 patients, and additional TEVAR was performed. One patient had a proximal retrograde type A dissection; the patient was in an acceptable state of health apart from persistent chest and back pain, and is still in follow-up. Spinal cord ischemia, stent displacement and collapse did not occur.

CONCLUSIONS

TEVAR is reliable and safe, and it can be widely applied in treating Stanford type B aortic dissection.
