title: [Mid- and long-term result of celiac artery coverage in TEVAR treatment for aortic dissection].
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.
