Objective To evaluate thoracic endovascular aortic repair for type B aortic dissection.Methods Chnical data were reviewed on 126 cases with type B aortic dissection undergoing endovascular aortic repair in our hospital from January 2006 to April 2011.There were 86 male patients and 40 female patients,age from 32 to 82 years.The stent- grafts were introduced via femoral arteriotomy.Stent-grafts were implanted to blockade tears of aortic dissection under the guidance of DSA.Postoperatively patients were followed-up by angiography and imiging for endoleak,stent migration,and fracture of stent-graft.Results In all cases,the aortic dissection tears were closed,true lumens were opened,and organ function was restored.There were not complications such as internal hemorrhage due to trauma or stent displacement on CTA from 3 to 63 months after endovascular therapy.Procedure was successful in all 126 cases,157 stents were released,2 cases died in the perioperative period,1 case died during the followed-up.A breach was found at the end of the stent in 12 cases,endovascular aortic repair redone successfully with a retrograde type A dissection found during follow-up.Conclusions Endovascular aortic repair is safe and effective for patients with Stanford type B aortic dissection with a favorable outcomes.

Objective To evaluate improved effect for deep venous valve function after superficial vein surgery of lower extremity in the intermediate stage.Methods Totally 43 patients (55 limbs) with varicose veins of lower extremity were enrolled to accept surgical management of vein systems in our department from March 2006 to October 2006.All patients were respectively followed up after 6 months and 4 years about the changes of deep venous valve function with color Doppler ultrasonography.Results Thirty-nine patients’ deep venous valve function kept well up to now,and there was no significant difference between the two results.Four patients without proximal saphenous vein ligation recurred,and there was reflux in deep venous.Conclusion Endovenous laser treatment and ablation of varicose veins of lower extremity with deep venous insufficiency could improve deep venous valve function effectively.Proximal great saphenous vein ligation is important for successful operation.

Objective To discuss the application of double parallel stent for preserving arch branch vessels during thoracic endovascular aortic repair.Methods During the period from June 2015 to June 2016,double parallel stents were carried out in 9 cases at department of vascular surgery,the People's Hospital of Xinjiang Uygur Autonomous Region.Results One patient died of an acute ischemic stroke and subsequently resulted in multiple organ failure after thoracic endovascular aortic repair.Eight patients received an aorta CT angiography during follow up at 1,3,6 months.During follow up,the patency rate for double parallel stents was 100%.There were no endoleak in 8 cases.Conclusion Double parallel stents are suited to patients with emergency situation and unsuited to open surgery in complicated aortic arch pathologies.Surgical approach is determined by preoperative evaluation.Prevention of endoleak and stroke is important in all cases.
