    Abstract:
    To observe the mid- and long-term result of intentional coverage of celiac artery in thoracic endovascular aortic repair (TEVAR) surgery for aortic dissection.
 Methods: We retrospectively analyzed 21 cases who received TEVAR with celiac artery coverage during the operation. The existence of collaterals between celiac artery (CA) and superior mesenteric artery (SMA) was confirmed by preoperative CT angiography (CTA) or digital substract angiography (DSA) for each patient. We used the stent-graft precisely above the orifice of SMA. Follow-ups were carried out at 2 weeks, 1 month, 3 months, 6 months, 1 year after the operation, and once per year thereafter.
 Results: No signs of visceral artery ischemic syptoms such as liver dysfunction, abdominal pain or distention were observed after the operation. There was no signs of spinal cord ischemia (SCI). Seven cases showed type II endoleak upon completion DSA but stopped automatically within 3 months. CTA in follow-ups showed thrombosis formation in false lumen.
 Conclusion: The intentional coverage of CA during the TEVAR for aortic dissection is safe and effective. The incidence of post-operative SCI or visceral artery ischemia is low. Type II endoleak is a major complication but it can be ceased automatically after medication. 目的：观察Stanford B型主动脉夹层胸主动脉腔内修复术(thoracic endovascular aortic repair，TEVAR)中覆盖腹腔干动脉的中远期临床疗效。方法：2007年7月至2015年7月，中南大学湘雅二医院血管外科收治累及腹腔干动脉Stanford B型主动脉夹层患者21例，术前对患者进行了详细的CT三维血管重建(CT angiography，CTA)或数字减影血管造影(digital substract angiography，DSA)检查以确认腹腔干动脉与肠系膜上动脉间侧支循环的存在。术中精确定位释放支架，同时覆盖腹腔干动脉及近腹腔干动脉的主动脉破口。随访分别在术后2周、1个月、3个月、6个月、12个月进行，之后每年进行1次随访。结果：所有患者术后均无肝功能损害，无腹痛、腹胀等脏器缺血症状。所有患者均未发生脊髓缺血症状。7例患者术后即时造影有内漏发生，但经保守治疗后3个月内均自行停止。余14例患者术后即时造影均未发现内漏，术后CTA复查可发现假腔内血栓形成，假腔逐渐缩小。结论：TEVAR治疗Stanford B型主动脉夹层术中有计划地覆盖腹腔干动脉可以有效覆盖近腹腔干动脉开口的主动脉夹层破口。术后出现腹腔内脏器缺血或脊髓缺血的概率较低。术后II型内漏是其主要并发症，但多可经保守治疗后自行停止。.
