Abstract:
Objective To evaluate the short-term and mid-to-long-term clinical effectiveness of endovascular isolation technique with covered-stent in treating Stanford type B aortic dissection. Methods A total of 183 patients with Stanford type B aortic dissection, who were admitted to authors’ hospital during the period from January 2005 to December 2013 to receive endovascular isolation treatment with covered-stent under general anaethesia, were enrolled in this study. The clinical data, including post-operative symptoms, complications, retention time in ICU, hospitalization days, 30-day mortality, etc. were retrospectively analyzed. After discharged from hospital, the patients were followed up to check the situation, position and shape of the stent, the diameter of dissection false lumen, the internal leakage, etc. The survival rate and the quality of life were determined. Results Endovascular isolation procedure with covered-stent was successfully accomplished in all the 183 cases. The retention time in ICU was (3.08 ± 1.93) days, the mean hospitalization time was (3.08 ± 1.93) days, and the 30-day mortality was 1.09%. After discharged from hospital, the patients were followed up regularly, and no collapse or displacement of stent was observed, and the stent remained in its normal shape. No recurrence of dissection, rupture or reversal tear was observed. No long existing internal leakage could be detected. During the follow-up period 4 patients died, among them three died from cerebral infarction and one died of natural death. The 5-year survival rate was 97.82% and the patient’s quality of life did not become apparently worse. Conclusion For the treatment of Stanford type B aortic dissection, endovascular isolation therapy with covered-stent has excellent short-term effect and stable mid-to-long-term result.
