Objective：To analyze the follow up effect of acute deep venous thrombosis（DVT）of the lower extremities through a contralateral femoral vein approach by percutaneous mechanical thrombolysis（PMT）combined with catheterdirected thrombolytic（CDT）therapy.Methods：From September 2016 to August 2017，45 patients were treated with PMT + CDT via contralateral approach，including 23 patients in the early thrombus group（0～7 days）and 22 patients in the late thrombus group（8～14 days）.The competent femoral valves，venous recanalization and the postthrombotic syndrome（PTS）rate in the two groups were analyzed and compared.Results：During the followup period of 20 months，37 patients with intact femoral vein valve function were observed，there was no statistical difference between the two groups；all iliac vein recanalization；the number of femoral popliteal recanalization（23 vs 17）and calf vein recanalization（22 vs 17）in the early thrombus group was higher than that in the late thrombus group.The incidence of post thrombosis syndrome（PTS）was 22%.and the early thrombus group was superior to the late thrombus group（10 vs.0）.Conclusion：The results of midterm followup confirmed that it is a feasible method to use contralateral approach to PMT + CDT for extensive acute DVT The incidence of PTS in early thrombus group was lower than that in late thrombus group.

Objective：To compare the clinical effectiveness of radiofrequency ablation（RFA）combined with local point stripping and endovenous laser treatment（EVLT）combined with high saphenous vein ligation in the treatment of varicose veins of lower extremity.Methods：120 patients with varicose veins of lower extremity were treated with intravascular radiofrequency ablation combined with local point stripping（60 cases，group R）and EVLT combined with high saphenous vein ligation（60 cases，group E）.Duration of the operation，intraoperative blood loss，total hospitalization cost，length of hospital stay，and postoperative complications（pain，swelling，local hematoma，skin infection，Incidence of burn，saphenous nerve injury）of the patients were compared.Results：There was no significant difference in the operation time between the two groups.However，there were more bleeding in the group E than in the group R，longer hospital stay，higher cost of hospitalization，and higher postoperative complications.The difference was statistically significant（P<0.05）.Conclusion：Intracavitary radiofrequency ablation combined with local point stripping is superior to endovenous laser treatment combined with high saphenous vein ligation，and it is safe，with less intraoperative bleeding，quick recovery，and low treatment cost，the advantages of less postoperative complications.

Objective:To to explore the predictive factors of the success rate of flexible ureteroscopic lithotripsy (fURL) in the treatment of single kidney stone.Methods:We retrospectively analyzed 144 patients with single kidney stone who underwent fURL in our hospital from January 2016 to December 2017.Evaluating the relationship between sex，age，body mass index (BMI)，preoperative catheterization，preoperative ESWL history，operator experience，stone location，hydronephrosis，stone diameter，stone volume，density (Hounsfield unit，HU) and the success rate of fURL.Logistics multivariate regression analysis was used to identify the independent predictors affecting the success rate of fURL.Results:There were significant differences in stone location，hydronephrosis ，experience and stone volume in univariate analysis(P<0.05).Multivariate regression analysis showed that lower calyceal stone，no hydronephrosis，less than 100 fURL experience and stone volume  were statistical significance(P<0.05).Conclusion:Stone location，hydronephrosis，operative experience and stone volume may be important predictive factors for the success rate of fURL in the treatment of single kidney stone.

Complex abdominal aortic aneurysms（CAAA）generally refer to shortneck abdominal aortic aneurysms（AAA）or abdominal aortic aneurysms involving visceral branch arteries.The treatment difficulties are mainly reflected in the adequate assessment of the proximal anchoring area of the neck and the revascularization of the visceral arteries.At present，the main techniques are “parallel stent graft”，“fenestrated” and“branched stent”.Parallel stent is represented by “chimney stents”，and it is usually used in highrisk patients in emergency situations or who are unavailable for the fenestrated stents.“Fenestrated stent graft”，as the main method for treatment of CAAA in recent years，has good safety and effectiveness，and gradually develops from a simple fenestration to a “fenestrated+branched”combination.The above technologies have their own advantages and disadvantages.This article will briefly explain various techniques for the treatment of complex abdominal aortic aneurysms，and provide some evidence for the endovascular treatment strategy of CAAA.

Hemodialysis access stenosis is one of the most common complications in hemodialysis patients.Endovascular intervention has become the first choice for the treatment of vascular stenosis，but restenosis after endovascular intervention has become a difficult problem in the field of hemodialysis access.According to the location，restenosis can be divided into peripheral restenosis and central venous restenosis.The treatment methods include percutaneous transluminal angioplasty，percutaneous transluminal stent implantation，open surgery and so on.With the development of new technology，there are many new treatment options for restenosis，such as drug-coated balloon，stent graft，hemodialysis reliable outflow graft device and so on.The patency rate of restenosis treatment can be improved by reasonable selection and usage of these new methods.

BuddChiari syndrome is rare disorder by hepatic venous outflow obstraction and resulting portal hypertension and（or）hypertension of infeior vena cava.Etiological factors include hypercoagulable conditions，myeloproliferative desenses and enviroment conditions.The diagnosis is establisbed by demonstrating obstruction of hepatic venous outflow by ultrasound，computed tomography or magnetic resonance.The main goals of treatment are to ameliorate hepatic congestion and prevent further thrombosis.The selective use of anticoagulation，revascularization，transjugular intrahepatic portosystemic shunt has resulted in a significant increase.Orthotopic liver transplant should be used as a rescue therapy.The epidemiology，etiology and pathogenesis，diagnosis，mangement and longterm followup of patiens with budd-Chiari syndrome is reviewed.
