[Endovascular graft exclusion with digital subtraction angiography for treatment of Stanford type B aortic dissection].
OBJECTIVE
To assess value of endovascular graft exclusion (EVGE) with digital subtraction angiography (DSA) in the treatment of Stanford type B aortic dissection (AD).


METHODS
On the basis of diagnosis with multi-slice spiral CT (MSCT), DSA was performed in 20 Stanford B AD cases for further diagnostic confirmation and EVGE was conducted for treatment. The DSA findings of the cases and the therapeutic effect of EVGE were evaluated.


RESULTS
In the 20 cases of Stanford type B AD, altogether 22 stents were implanted during EVGF with a stent release success rate of 100%. Postoperative examination revealed no obvious leakage or false lumen in 15 cases, and death occurred in 1 case 6 days after the operation due to right renal hemorrhage and infection, and the rest 19 patients were cured and discharged. Follow-up of the patients demonstrated improvement in the clinical symptoms, and MSCT showed that all the dissections were sealed successfully. No severe complications were observed 3 months after the treatment in these patients.


CONCLUSIONS
DSA can identify the fine anatomy of AD and allowed intraoperative monitoring in EVGE, which is an effective and safe means for treatment of Stanford type B AD.
