Endovascular repair of acute Stanford B-type aortic dissections with domestic stent grafts in China: early and mid-term results.

PURPOSE

To review the results of endovascular treatment of acute aortic dissections with domestic stent-grafts at a single center.

METHODS

Data from all 51 patients who presented with acute aortic dissections (ADs, Stanford B type) between April 2004 and May 2009 and underwent endovascular interventions with domestic stent grafts were retrospectively reviewed. Of these patients 50 had primary ADs and 1 had a traumatic AD. All patients were followed up for from 1 to 48 months (average, 15.11 ± 10.93 months).

RESULTS

There was no strut failure or surgical conversion in any of the patients. Intraoperative angiography documented the complete seal of the primary entry. Two deaths occurred during hospitalization. One patient died due to aortic rupture 24 h after the procedure, and the other died of myocardial infarction 3 days later. Two patients (4.1%) died during the follow-up period. A Kaplan-Meier analysis revealed a 4-year survival rate of 92.16%.

CONCLUSIONS

Endovascular treatment for acute Stanford B-type ADs with domestic stent grafts is both safe and effective, while also demonstrating an acceptable survival rate and mid-term clinical outcomes.
