To assess value of endovascular graft exclusion (EVGE) with digital subtraction angiography (DSA) in the treatment of Stanford type B aortic dissection (AD).
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.
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.
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.
评估数字减影血管造影（DSA）引导下血管腔内隔绝术（EVGE）治疗Stanford B型主动脉夹层（AD）的价值。
在多层螺旋CT（MSCT）诊断的基础上，对20例Stanford B型AD患者行DSA检查以进一步明确诊断，并采用EVGE进行治疗。评估患者的DSA表现及EVGE治疗效果。
20例Stanford B型AD患者行EVGE共植入22枚支架，支架释放成功率为100%。术后复查15例无明显内漏及假腔形成，1例术后6天因右肾出血感染死亡，其余19例治愈出院。随访患者临床症状改善，MSCT显示夹层均成功封闭。治疗后3个月患者未出现严重并发症。
DSA能够清晰显示AD的精细解剖结构并可在EVGE术中进行监测，是治疗Stanford B型AD安全、有效的方法。
