Abstract:
Objective
To evaluate the early and midterm outcomes of endovascular repair of Stanford type B aortic dissection(BAD).
Methods
Patients with BAD were studied retrospectively following the endovascular repair.Between January 2001 and December 2006, 121 patients (males=113, females=8)with BAD were treated with endovascular repair.The mean age of the patients (30 years to 79 years)was 56.7years.Among them,35 patients had acute BAD (the interval between onset and surgery≤7 days),57 patients had subacute BAD(the interval between onset and surgery was from 8 days to 30 days)and 29 patients had chronic BAD (the interval between onset and surgery＞30 days).
Results
The technical success rate was 100%. The rate of endoleak revealed within 30 days was 6.0%and neurologic complication rate was 3.3%.The overall mortality rate within 30 days was 4.1%,the mortality of acute BAD,subacute BAD and chronic BAD was 2.9%,0%,and 13.8%,respectively.The follow-up rate was 93.1%.Mean follow-up was 17.5 months(1 to 67 months).By using CTA,complete thrombosis in false lumen was revealed in 44.3% of patients, while partial thrombosis was revealed in 55.7% of patients.The mortality during follow-up was 2.8%.
Conclusions
According to the early and midterm results,endovascular repair of BAD is a microinvasive,safe and effective treatment.However,the long-term efficacy still needs to be evaluated.
