Objective To evaluate the safety and efficacy of the endovascular treatment of subclavian artery stenosis.Methods From January 2010 to December 2015,the clinical data of 93 patients with subclavian artery stenosis were analyzed retrospectively.All the patients were received angiography and endovascular treatment.Results The technical success rate was 97.9％.Clinical symptom remission rate was 97.8％ after the treatment.There was no procedure related death.During the procedure,limited arterial dissection was encountered in two cases.One patient had minor cerebellar hemorrhage.The follow-up time was 12 to 60 months.Median follow-up time was 36 months.Restenosis was occurred in nine cases.The patency rate of 5 years was 81.0％.Conclusions Endovascular treatment was a safe and effective treatment as the result of our data.It should be used as the preferred treatment of choice for subclavian artery stenosis.

Objective To investigate the effectiveness of endovascular technique in treatment of acute arterial hemorrhage of abdominal organs.Methods Totally 159 cases (145 patients) acute arterial hemorrhage of abdominal organs were enrolled.All patients underwent emergency transarterial angiography.Endovascular treatment by spring coil,gelatin sponge,or covered stent were in 40 cases.The success rate of immediate and long-term hemostasis was judged by the postoperative radiography,symptoms and the changes of vital signs and laboratory results.Results The positive signs in angiography were observed in 47 among the total 159 cases (47/159,29.56％).Seventy-seven postoperative hemorrhage cases underwent angiography and 29 cases (29/77,37.66 ％) were positive,82 non-operative hemorrhage cases underwent angiography and 18 cases (18/82,21.95％) were positive.The difference was statistical significant (P＜0.05).Endovascular treat ment were performed in 40 cases (33 by spring coils,4 by gelatin sponge and 3 by covered stent).Hemorrhages were con trolled immediately in all the 40 cases after embolization and the success rate were 100％.Conclusion Endovascular tech nique is minimal invasive,and it is an effective method for treatment of acute arterial hemorrhage in abdominal organs.

Objective:To evaluate the safety and efficacy at 1-year follow-up of the use of drug-coated balloon (DCB) for the treatment of femoropopliteal in-stent restenosis (ISR).Methods:This study enrolled 252 patients undergoing Orchid DCB angioplasty for peripheral arterial disease in the femoral-popliteal segment. The clinical data were retrospectively analyzed.Results:Forty-nine patients were eligible, including 29 (59.2%) chronic total occlusions belonging to TransAtlantic Inter-Society Consensus-Ⅱ(TASC Ⅱ) D, 7 (14.3%) thrombosis, and 14 (28.6%) moderate to severe calcifications. The mean lesion length was (215.9±97.1) mm. 69.4% were of occlusive lesions (Tosaka Ⅲ category). Only 1 provisional stent was implanted. 98% patients had severe claudication or even worse. Of these cases, 34 (73.9%) showed improvements in Rutherford category, while 11 (23.9%) did not change and 1 (2.2%) case deteriorated. The average value of ABI was 0.478±0.264 before surgery and 0.907±0.207 at the end of follow-up. The improvement in Rutherford category ( P<0.01) and ABI ( P<0.005) were both significant. The primary patency (PP) was 80.4%, and the freedom from clinically driven TLR was 84.8% at 1 year. During the follow-up period, there was no all-cause death and major limb amputation. Conclusion:This multicenter study demonstrated the effectiveness of DCB as a treatment for complicated and extensive ISR lesions within 12 months.
