Objective To investigate the clinical efficacy of continuous arterial catheter directed thrombolysis for ischemia disease of lower extremity.Methods Retrospective analysis of clinical data of 29 patients undergoing continuous arterial catheter directed thrombolysis from June 2016 to June 2018 in Department of Aortic and Vascular Surgery Center,Fuwai Hospital,CAMS&PUMC was conducted.There were 25 males and 4 females,aged (65.3 ± 11.2) years,with an age range of 51-81 years.The patients were diagnosed after admission and received continuous arterial thrombolysis.After thrombolytic therapy,estimate was conducted whether to place the stent further based on the result of angiographit.The patients' pain symptom relief,embolism,bleeding and other complications were observed in the 6 months,12 months and 24 months by telephone follow-up or outpatient review.Meanwhile,the patients improved the color Doppler ultrasound examination.Results The 21 patients were markedly effective,7 patients were effective,and 1 patient was ineffective in all the 29 patients who accepted the continuous arterial catheter directed thrombolysis therapy.Two of the patients developed distal toe arterial embilization during thrombolysis and improved after drug treatment.The total effective rate was 96.5％ (28/29).Stents implant rate was 20.7％ (6/29).The follow-up rate was 86.2％ (25/29).No symptom relapse was observed.Conclusion Continuous arterial catheter directed thrombosis for ischemia disease of lower extremity is minimally invasive,safe and effective.

Objective To compare the clinical features and surgical outcomes of hepatocellular carcinoma (HCC) combined with portal venous tumor thrombus (PVTT) and hepatic venous tumor thrombus (HVTT) or bile duct tumor thrombi (BDTT),and analyze the effects of different tumor thrombus (TT) types and different surgical methods for TT on prognosis.Methods The retrospective cross-sectional study was conducted.The clinical data of 220 HCC patients with lymphovascular invasion (LVI) who were admitted to the Affiliated Cancer Hospital of Guangxi Medical University between January 2004 and December 2014 were collected.Of 220 patients,140 were combined with PVTT,36 with HVTT and 44 with BDTT.According to patients' conditions,they underwent tumor and TT resection,and tumor resection + TT removal or single TT removal.Observation indicators:(1) comparisons of clinical features of HCC patients with PVTT or HVTT or BDTT;(2) surgical and postoperative situations;(3) follow-up and survival.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival up to December 2015.Measurement data with normal distribution were represented as (x)±s.Comparisons among 3 indicators were analyzed using the one-way ANOVA,and comparisons between 2 indicators were analyzed using the t test.Comparisons of count data were analyzed using the chi-square test.The survival curve and rate were respectively drawn and calculated by the Kaplan-Meier method,and the Log-rank test was used for survival analysis.Results (1) Comparisons of clinical features of HCC patients with PVTT or HVTT or BDTT:number of patients with Child-pugh A,Child-pugh B and peritoneal effusion,tumor diameter and cases with tumor capsule were respectively detected in 133,7,23,(10±4)cm,91 in HCC patients with PVTT and 35,1,4,(9±4)cm,27 in HCC patients with HVTT and 35,9,16,(6±4)cm,15 in HCC patients with BDTT,with statistically significant differences (x2 =12.693,10.408,F=11.300,x2 =17.188,P＜ 0.05).(2) Surgical and postoperative situations:of 140 HCC patients with PVTT,51 underwent tumor and PVTT resection,89 underwent tumor resection + PVTT removal through incising portal vein;68 received postoperative transcatheter arterial chemoembolization (TACE).Thirty-six HCC patients with HVTT underwent tumor and HVTT resection;24 received postoperative TACE.Of 44 HCC patients with BDTT,23 underwent tumor and BDTT resection,21 underwent tumor resection + BDTT removal through incising common bile duct;29 received postoperative TACE.(3) Follow-up and survival:① 220 patients were followed up for 1-73 months,with a median time of 12 months.The median survival time,1-,3-and 5-year survival rates were respectively 12 months,48.2％,25.0％,15.4％ in 140 HCC patients with PVTT and 28 months,77.1％,45.6％,24.5％ in 36 HCC patients with HVTT and 36 months,88.6％,48.3％,24.6％ in 44 HCC patients with BDTT,with a statistically significant difference in survival (x2 =13.316,P＜0.05).② Of 140 HCC patients with PVTT,49 were in type Ⅰ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 20 months,60.3％,32.6％ and 17.1％;70 were in type Ⅱ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 13 months,51.4％,26.0％ and 17.3％;21 were in type Ⅲ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 7 months,9.5％,4.8％ and 0,showing a statistically significant difference in survival (x2=18.102,P＜0.05).The median survival time,1-,3-and 5-year survival rates were respectively 21 months,72.5％,42.5％,26.2％ in 51 patients undergoing tumor and TT resection and 9 months,40％,14.4％,0 in 89 patients undergoing tumor resection + PVTT removal through incising portal vein,showing a statistically significant difference in survival (x2=24.098,P＜0.05).③ Of 36 HCC patients with HVTT,17 were detected in right HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 14 months,64.7％,20.2％ and 0;10 were detected in left HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 53 months,80.0％,70.0％ and 38.9％;9 were detected in middle HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 40 months,88.9％,61.0％ and 30.5％;showing no statistically significant difference in survival (x2 =5.951,P＞0.05).④ Of 44 HCC patients with BDTT,24,6 and 14 were respectively detected in type Ⅰ,Ⅱ and Ⅲ BDTTs,and median survival time,1-,3-and 5-year survival rates were respectively 38 months,87.5％,60.4％,34.9％ in type Ⅰ BDTT patients and 26 months,83.3％,16.7％,0 in type Ⅱ BDTT patients and 35 months,78.6％,50.0％,21.4％ in type Ⅲ BDTT patients,showing no statistically significant difference in survival (x2 =5.312,P＞0.05).Of 44 patients,median survival time,1-,3-and 5-year survival rates were respectively 38 months,91.3％,59.5％,34.3％ in 23 patients undergoing tumor and TT resection and 26 months,85.7％,35.7％,15.3％ in 21 patients undergoing tumor resection + TT removal through incising common bile duct,showing no statistically significant difference in survival (x2 =2.071,P＞0.05).Conclusions HCC patients with PVTT have larger tumor diameter and worse liver dysfunction,and are prone to peritoneal effusion.HCC patients with different LVI undergo surgery.There is better prognosis in HCC patients with BDTT,and good prognosis in patients with HVTT,while poorer prognosis in patients with PVTT.The postoperative survival of HCC patients with PVTT is associated with TT type,and patients will have better prognosis after tumor resection + TT removal if TT type is confirmed earlier.The postoperative survival of HCC patients with BDTT is not associated with TT type,tumor resection + TT removal maybe prolong postoperative survival time.

ObjectiveTo investigate the safety and efficacy of re-hepatic resection (rHR) versus radiofrequency ablation (RFA) in the treatment of recurrent hepatocellular carcinoma (RHCC) in Asia through a meta-analysis. MethodsPubMed, CNKI, and Wanfang Data were searched for related studies published up to June 15, 2020. Two reviewers independently searched for the articles and extracted related data, and RevMan 5.4.1 was used to perform the meta-analysis. ResultsA total of 2 randomized controlled trials and 18 retrospective cohort studies met the inclusion criteria and involved 2903 patients with RHCC from Asian countries. The mortality rate in the perioperative period was 2% in the rHR group and 0 in the RFA group, and the incidence rate of perioperative complications was 22.4% in the rHR group and 3.3% in the RFA group. The 1-, 3-, and 5-year overall survival rates were 92.3%, 66.3%, and 51.1%, respectively, in the rHR group and 91.4%, 69.2%, and 39.9%, respectively, in the RFA group. The 1-, 3-, and 5-year disease-free survival rates were 67.9%, 48.3%, and 34.4%, respectively, in the rHR group and 57.5%, 27.9%, and 14.0%, respectively, in the RFA group. The Meta-analysis showed that there was no significant difference in overall survival rate between the two groups (hazard ratio ［HR］=089, 95% confidence interval ［CI］: 0.77-1.02, P=0.10), while the rHR group had a significantly higher disease-free survival rate than the RFA group (HR=0.79, 95% CI: 0.72-0.87, P＜0.001). ConclusionCurrent evidence shows that rHR may help to achieve a higher disease-free survival rate than RFA in the treatment of RHCC, while rHR and RFA have a similar overall survival rate.

Objective:To summarize the clinical efficiency of paclitaxel drug coated balloon (DCB) in femoral popliteal artery disease.Methods:Retrospective analysis was made on 125 patients (141 limbs) admitted from Jun 2016 to Jul 2019 for femoral popliteal disease treated with DCB.Results:Median follow-up time was 19 months. The average lesion length was (138±78) mm, with an overall cumulative primary patency rate of 81.4% and 60.8% at 12 and 24 months postoperatively and f-TLR rates of 90.1% and 83.0%, respectively. In a total of 109 primary lesions, subgroup analysis showed that among the TASC C/D primary lesions, the primary patency rate was significantly lower in those with combined severe calcification and the f-TLR rate in those with popliteal involved lesions. TASC grade C/D lesions, severe calcified lesions were independent risk factors for patency, while hypertension was an independent protective factor.In-stent restenosis (ISR) target lesions involving the popliteal segment had a significantly worse prognosis than ISR of the superficial femoral artery.Conclusion:DCB in the treatment of lower femoral popliteal artery lesions can achieve a satisfactory medium-term patency outcome, while the efficacy for complex lesions still needs further improvement.

Objective To study the correlation between serum prealbumin level before liver resection and prognosis of patients with primary hepatocellular carcinoma (HCC).Methods The clinical data of patients with HCC who underwent liver resection at the Affiliated Tumor Hospital of Guangxi Medical University from August 2007 to October 2016 were retrospectively analyzed.The previous albumin of 200 mg/L and the pre-albumin as predicted by the maximum selection rank statistic method were used as the bounding group,and reduced groups and the correlation between pre-operative serum pre-albumin levels and clinicopathological characteristics were analyzed.The Kaplan-Meier method was used to calculate the overall survival rate of patients with the different cutoff levels.The Cox proportional regression model was used to analyze,and cirrhosis,alpha-fetoprotein levels and Barcelona Clinic Liver Cancer staging were used to adjust the relationship between serum prealbumin and prognosis of liver resection for HCC patients.Analysis of stratified variables was performed and their interactions with serum prealbumin were analyzed.Results Of the 2 022 patients included in this study,there were 1 739 males and 283 females.Their age was 49.5 ± 11.2 years.The median follow-up was 37.4 months.The optimal cutoff value of prealbumin predicted by the maximum selection rank statistic method was 166 mg/L.Regardless of the cutoff values of previous albumin 200 mg/L or prealbumin 166 mg/L,multivariate analysis showed that preoperative serum prealbumin level was an independent prognostic risk factor for patients (P ＜0.05).The prognosis of patients with ＞200 mg/L (＞ 166 mg/L) serum prealbumin before surgery was significantly better than that of patients with ≤200 mg/L (≤166 mg/L) prealbumin,the differences were significant (all P ＜ 0.05).After adjusting for confounding factors,the prealbumin level correlated with prognosis of patients with HCC [cutoff value 200 mg/L:HR (95％ CI) was 1.59 (1.35-1.86),cutoff value 166 mg/L:HR (95％ CI) was 1.69 (1.44-1.98),all P ＜ 0.05].The results of stratified analysis showed that the relationship between prealbumin levels and the prognosis of HCC patients became more robust.Conclusions Preoperative serum prealbumin was an independent risk factor for prognosis of HCC patients,and it had predictive value on prognosis of HCC patients.

Objective To evaluate the efficacy of staged carotid artery stenting and coronary artery bypass grafting in the treatment of coronary heart disease complicated with carotid stenosis. Methods The clinical data of patients with coronary heart disease and carotid stenosis treated in Fuwai Hospital from November 2019 to September 2021 were retrospectively analyzed. All patients underwent staged carotid artery stenting and coronary artery bypass grafting. The incidence and risk factors of severe complications such as myocardial infarction, cerebral infarction and death during the perioperative period and follow-up were analyzed. Results A total of 58 patients were enrolled, including 47 males and 11 females with an average age of 52-77 (64.2±5.6) years. No complications occurred before coronary artery bypass grafting. There was 1 myocardial infarction, 1 cerebral infarction and 1 death after the coronary artery bypass grafting. The early complication rate was 5.2%. During the follow-up of 18.3 months, 1 cerebral infarction and 2 deaths occurred, and the overall complication rate was 10.3%. According to Kaplan-Meier survival curve analysis, patients with symptomatic carotid stenosis (log-rank, P=0.037) and placement of close-cell (log-rank, P=0.030) had a higher risk of postoperative ischemic cerebrovascular event, and patients with previous cerebral infarction had a higher risk of postoperative severe complications (log-rank, P=0.044). Conclusion Staged carotid artery stenting and coronary artery bypass grafting is safe and feasible for the treatment of coronary heart disease complicated with carotid stenosis.
