Objective To evaluate the safety and efficiency of transcatheter anastomotic leakage closure after surgical procedures for non-infected ascending aortic pathology with different occlusion devices. Methods From Dec. 2013 to Sep. 2015, six cases received interventional therapy for anastomotic leakage after surgical procedures for non-infected ascending aortic pathology using occluders. Four cases were with proximal graft-vessel anastomotic leakage, including two pseudoaneurysms at the site of aortic roots and two ascending aorta to right atrium shunts. The other two cases were with artificial grafts to intraoperative stent anastomotic leakage leading to endoleak type Ib. The anastomotic leakage was totally occluded by single ADOⅡrespectively in four cases. Two detachable coils were implanted in one case with artificial graft to intraoperative stent anastomotic leakage, but mild residual shunt to false lumen was detected by DSA and follow-up CTA. The second interventional procedure was carried out one month later, and one ADO Ⅱ was used to close the residual leakage totally. One PDA occluder was implanted along arteriovenous guide-wire track via aortic root to right atrium fistula in one case. Results All the anastomotic leakages of the six cases were totally excluded by different occlude devices percutaneously. The technical success rate was 100%. Follow-up time was from 1 month to 4 years. The patients' clinical condition improved obviously. Follow-up CTA showed no recurrence of anastomotic leakage. Complete thrombosis and marked shrinkage of the pseudoaneurysm were achieved in two cases, and the partial thrombosis and shrinkage of the false lumen were achieved in 2 cases. Conclusion Trans-catheter closure is an alternative treatment for ascending aortic surgical anastomotic leakage, which may achieve satisfactory short-and mid-term results.

Objective:
To investigate the effect of emergency thoracic endovascular aortic repair (TEVAR) in patients with acute traumatic thoracic aortic injury.
Method:
From January 2014 to December 2016, a total of 35 patients with acute traumatic thoracic aortic injuries were treated with emergency TEVAR in our hospital, their clinical data were analyzed retrospectively in this study.
Results:
The patients were 42 (34, 55) years old,and there were 31 males.All cases were diagnosed by emergency aorta computed tomography angiography (CTA),and 5 cases were diagnosed as aortic transaction, 13 cases were diagnosed as aortic pseudoaneurysm, 7 cases were diagnosed as aortic dissection, and 10 cases were diagnosed as aortic intramural hematoma combined hemothorax.The concomitant injuries included cerebral contusion (3 cases, 8.6%), pulmonary contusion with rib fracture (31 cases, 88.5%), long bone fracture (7 cases, 22.5%), contusion of viscera or internal organs (3 cases, 8.6%).Emergency TEVAR were performed with vascular suture system preset under local anesthesia after diagnosis,and combined injury was treated in related departments.CTA was repeated after 1, 3 and 6 months and yearly thereafter. One patient died before transferring to catheter room,and 34 (97.1%) patients underwent TEVAR procedure successfully.Time from door to operating room was (88.6±26.6) minutes,and the procedure time was (52.0±9.4) minutes. A total of 69 Perclose Proglide vascular suture system were used,and 2 cases underwent surgical suture because of hematoma and pseudoaneurysm formation in femoral arteries.The involved length of thoracic aorta was (44.5±7.4)mm. A total of 46 stent-grafts were implanted, the length of stent-graft was (164.3±15.2)mm,and the proximal oversize rate was (22.3±8.6)%. The follow-up time was 24 (12,24) months, and there were no procedure related complication such as endoleak and paraplegia. Complete aortic remodeling was observed in 14 cases. Fully thrombolization at stent segments were observed in 7 cases. Fully thrombalization of pseudoaneurysms were observed in 13 cases. One patient complained mild left upper limb weakness due to left subclavian artery occlusion.
Conclusion
Emergency TEVAR is safe and effective procedure for the treatment of patients with acute traumatic thoracic aortic injury.

Objective:
To investigate the feasibility and efficacy of transcatheter closure of anastomotic leakage after aortic surgery using Amplatzer Vascular Plug Ⅲ (AVP Ⅲ).
Methods:
A retrospective analysis was performed in 5 patients with anastomotic leakage after aortic surgery, who underwent transcatheter closure in our hospital from January to June 2017 using AVP Ⅲ. Surgeries were performed in 3 cases of Standford type A dissection, 1 case of ascending aortic aneurysm and 1 case of persistent truncus.There were 3 males,and age was (43.8±13.1) years old. Anastomotic leakages located at the ascending aorta in 4 patients, and the other one located between the aortic arch and the stent-graft.Three of them had aorta-right atrium fistula and patients suffered from progressive heart failure. False aneurysm between aorta and pulmonary artery was formed in 1 patient, and patent aortic false lumenwas found in the other patient. All the AVP Ⅲ were deployed based on a femoral arteriosus loop. Patients were followed up after transcatheter closure to observe the clinical results.
Results:
Six AVP Ⅲ were successfully implanted in the 5 patients. Trivial residual shunt was seen in 1 patient after closure. The patients were followed up 6 (1, 6) months. The cardiac function improved from NYHA class Ⅱ-Ⅳ to class Ⅰ-Ⅱ after the procedure in 3 congestive heart failure patients.The right atrium systolic pressure was significantly reduced after the procedure((8.7±1.8) mmHg (1 mmHg=0.133 kPa) vs. (24.3±2.3) mmHg,
