RESUMEN
Objective To evaluate the short-term effect of drug-coated balloon (DCB) with paclitaxel in treating in-stent restenosis (ISR) of femoral popliteal artery.Methods A total of 18 patients with femoral popliteal artery ISR,who were admitted to authors' hospital during the period from June 2016 to December 2016 to receive paclitaxel DCB treatment,were enrolled in this study.The patients included 15 males and 3 females,with a mean age of (72.7±9.8) years old.According to Fontaine classification,grade Ⅱ B was seen in 9 patients,grade Ⅲ in 8 patients,and grade Ⅳ in one patient.Preoperative CT angiography showed that ISR could be confirmed in 3 patients and complete occlusion of the stent in 15 patients.After the diseased artery was re-opened,pre-dilatation with common balloon was conducted,which was followed by dilatation with paclitaxel DCB;remedial stent implantation was carried out when the restrictive dissection was observed or if the residual stenosis was beyond 50％.Angiography was performed immediately after the procedure to check the vascular patency.On the third day afterthe treatment,the ankle-brachial index (ABI) of diseased lower extremity was determined to assess the improvement of ischemia.Three month after the treatment,the patients were followed up to detemine the incidence of restenosis,the clinically-driven target lesion revascularization (TLR) rate,and the occurrence of serious clinical events within 3 months.Results Successful re-opening of the diseased artery was achieved in all 18 patients,the technical success rate was 100％.At 3 months after the treatment,the restenosis rate and TLR rate were 10％ (1/10) and 6.67％ (1/15) respectively.No procedure-related complications occurred in all patients.Conclusion For the treatment of femoral popliteal artery ISR,the use of paclitaxel DCB is safe and effective.
RESUMEN
ObjectiveTo identify the risk factors related to the mortality of severe acute pancreatitis.Methods Clinical data of 57 cases of severe acute pancreatitis in our hospital from August 1997 to February 2004 were collected and analyzed retrospectively. There were 32 males and 25 females. The median age was 51 years. Cases were divided into death group and survival group according to their outcome. The characteristics, severity and surgical therapy were analyzed. ResultsEleven patients died, the mortality was 19.3%。 Thirty cases underwent surgery, 8 died, the mortality was 26.3%.Factors which were of significant differences between the two groups by univariate analysis were age, Ranson score, APACHEⅡscore, ascites, MODS, ARDS, heart failure and renal failure. Multivariate logistic regression showed that independent risk factors included age, ascites, MODS. ConclusionsIn case of severe acute pancreatitis,the independent risk factors related to mortality were age, ascites and MODS.
