Endovascular stent-graft implantation technique is a newly developed, effective and less invasive method in treating thoracic aortic dissection (TAD). Our study was designed to further verify the feasibility, the efficacy, and safety of this technique. We present a 4-year follow-up report of endovascular stent-graft treatment over 36 cases of acute TAD patients and 40 cases of chronic TAD patients. The mortality and comorbidity rates were evaluated thoroughly. In our study, the deployment of the stent-grafts was successfully performed in 75 cases. The hospital cumulative 30-day mortality rate was 1.3%. The instant endoleak rate was 15.8% (12 patients). All endoleaks were successfully treated with a second stent. All patients in local anesthesia were transported to the general ward after the intervention and were discharged from hospital within 1 week. Our preliminary results showed endovascular stent-graft implantation technique offered good peri-operative morbidity and mortality rates. Stent-graft placement over TAD produced a low incidence of spinal cord ischemia, cardiac and pulmonary complications, less hospital stay, less blood transfusion and became the first choice of TAD patients in our department.
血管内支架移植物植入技术是一种新开发的、有效且侵入性较小的治疗胸主动脉夹层（TAD）的方法。我们的研究旨在进一步验证该技术的可行性、有效性和安全性。我们呈现了对36例急性TAD患者和40例慢性TAD患者进行血管内支架移植物治疗的4年随访报告。对死亡率和合并症发生率进行了全面评估。在我们的研究中，75例患者成功完成了支架移植物植入。医院30天累积死亡率为1.3%。即刻内漏发生率为15.8%（12例患者）。所有内漏均通过植入第二个支架成功治疗。所有局部麻醉的患者在介入治疗后被转运至普通病房，并在1周内出院。我们的初步结果表明，血管内支架移植物植入技术具有良好的围手术期发病率和死亡率。TAD患者植入支架移植物后脊髓缺血、心脏和肺部并发症的发生率较低，住院时间较短，输血较少，成为我们科室TAD患者的首选治疗方法。
