ABSTRACT
@#Currently, transcatheter intervention has emerged as a first-line treatment for coarctation of the aortic. Due to the radiation exposure associated with catheter interventional therapy, there are numerous restrictions, which harms both patients and medical personnel and is dependent on sizable radiation apparatus. Here, we report for the first time a case of echo-guiding percutaneous aortic stent implantation for a 27 years female patient of reproductive age. After discharge, the patient's aortic coarctation pressure decreased to 18 mm Hg, and the surgical results were satisfactory.
ABSTRACT
In recent years, with the development of organ preservation, surgical techniques, perioperative management and immunosuppression regimens, the success rate of liver transplantation and survival rate of the recipients have been significantly enhanced. Liver transplantation has become the optimal treatment for patients with end-stage liver disease. However, biliary complications still commonly occur after liver transplantation, especially biliary anastomotic stricture. Severe biliary anastomotic stricture will not only increase the cost of treatment, but also lead to graft loss and even affect the survival rate of recipients. Therefore, timely diagnosis and treatment of biliary anastomotic stricture play a significant role in improving the survival rate of liver transplant recipients. In this article, the risk factors, clinical symptoms, diagnosis and treatment of biliary anastomotic stricture after liver transplantation were reviewed, aiming to provide novel ideas for the research, diagnosis and treatment of biliary anastomotic stricture after liver transplantation, and further enhance clinical efficacy of liver transplantation and the quality of life of recipients.
ABSTRACT
Objective To discuss the clinical value of systemic immune-inflammation index(SII)in predicting the prognosis of patients with extrahepatic cholangiocarcinoma(ECCA)treated with biliary stenting combined with 125I seeds implantation.Methods A total of 128 patients with unresectable ECCA,who received biliary stenting combined with 125I seeds implantation at the Interventional Department of the Affiliated Hospital of Xuzhou Medical University of China between August 2018 and August 2021,were enrolled in this study.The peripheral blood routine testing was performed within 3 days before operation,based on which the SII was calculated.Receiver operating characteristic(ROC)curve was applied to determine the optimal cut-off value of SII,based on which the patients were divided into high-SII group and low-SII group.Cox regression model was used to analyze the independent factors affecting patient prognosis.The Kaplan-Meier curve was plotted to analyze the one-year survival.Results The optimal cut-off value of SII was 1 050,the sensitivity was 66.0％,the specificity was 69.3％,and the area under ROC curve of SII was 0.676.The one-year survival rate of patients with ECCA in the high-SII group was significantly lower than that in the low-SII group(P＜0.05).Univariate Cox regression analysis indicated that vascular invasion,T stage,adjuvant chemotherapy,CA19-9,and preoperative SII were the important factors affecting the prognosis of patients with ECCA.Multivariate Cox regression analysis revealed that T stage,CA19-9,and preoperative SII were the independent risk factors for patient prognosis,while adjuvant chemotherapy was a protective factor.The Kaplan-Meier curves showed that the one-year survival rate in high-SII group was remarkably lower than that in the low-SII group.Conclusion Preoperative SII has an important value in evaluating the prognosis of patients with ECCA who are treated with biliary stenting combined with 125I seed implantation.(J Intervent Radiol,2023,32:1221-1225)
ABSTRACT
Objective To analyze the data of percutaneous coronary stent implantation related groups in certain hospi-tal of Beijing,so as to provide data support for promoting CHS-DRG payment reform and provide guidance and reference for its refined management.Methods The case data of local medical insurance patients in Beijing who received percutaneous coronary stent implantation from January 2020 to December 2021 in certain hospital were statistically analyzed,collect the medical insurance settlement information of the selected patients,and analyze the factors that affect their entry into FM19 group settlement.Results There are differences in the factors affecting FM19 inclusion in different reform stages,overtransfer personnel is a new independent factor that interferes with the group settlement in the actual operation stage.Some special operation codes may interfere with cases entering FM19 group due to pri-ority effect among disease groups.Conclusion The grouping settlement conditions of CHS-DRG are more complex,patients with different expense types need to be specifically analyzed according to the current grouping scheme and reimbursement policy.At present,there are relatively few disease groups settled by package for urban residents,and they continue to be affected by the rule of grouping priority.However,it is necessary to fully implement and strengthen the cost control of disease groups for urban employees,and rationally optimize the diagnosis and treat-ment plan to finely control medical costs.
ABSTRACT
Objective To explore the strategies of perioperative antithrombotic therapy in the patient undergoing revision total hip arthroplasty after coronary stent implantation. Methods The antithrombotic therapy in one patient undergoing revision total hip arthroplasty after coronary stent implantation was analyzed with the review of related literatures. Results The patient developed non-ST segment elevated myocardial infarction due to the stop of aspirin three days before operation and no low molecular weight heparin was used. The antithrombotic treatment and prevention of venous thromboembolism were analyzed. Conclusion Antithrombotic therapy should be selected reasonably in patients undergoing revision total hip arthroplasty after coronary stent implantation.
ABSTRACT
@#To investigate the safety and effectiveness of endovascular treatment for non-acute symptomatic intracranial occlusive disease of internal carotid artery. Methods The general data，surgical data and follow-up data of the patients with non-acute intracranial occlusion of internal carotid artery admitted to the Affiliated Hospital of Qingdaso Univerity from July 2016 to February 2021 were retrospectively analyzed，including the success rate of recanalization，the incidence of perioperative complications，imaging follow-up data and clinical follow-up data. Thrombolysis test for cerebral infarction （TICI） was used to evaluate the success of recanalization，the National Institutes of Health Stroke Scale （NIHSS） score was used to evaluate the degree of neurological impairment before and after treatment，and the degree of postoperative neurological recovery was evaluated by the modified Rankin Scale （MRS）. Results 28 of the 30 cases of intracranial internal carotid artery were successfully opened （technical success rate was 93.3%）. The difference of mTICI grading before operation was statistically significant compared with that after operation （P<0.05）.Surgical complications occurred in 6 cases （20.0%），including dissection in 2 cases，hyperperfusion syndrome in 1 case，and subarachnoid hemorrhage in 3 cases. Follow-up imaging of the 18 patients showed that 3 patients had restenosis of the offending vessels. One of them had TIA in the offending vessels and presented with paroxysmic contralateral limb weakness，and the other one had asymptomatic stenosis. In the 30 cases of clinical follow-up，there was a statistically significant difference in the MRS score between the 28 cases with successful operation and that before operation （P<0.05），and there was no significant change in the MRS score during clinical follow up between the 2 cases with intraoperative complications and unsuccessful operation. Conclusion endovascular therapy is safe and effective in highly selected cases of non-acute symptomatic intracranial internal carotid occlusion. The long-term NIHSS score and MRS score can be used to follow up the neurological deficit and recovery，and then to evaluate the long-term efficacy of endovascular therapy.

ABSTRACT
Objective To observe the efficacy of endoscopic nasal dacryocystoma anastomosis combined with stent implantation in the treatment of chronic recurrent dacryocystitis. Methods Thirty patients (30 eyes) with chronic dacryocystitis who had relapsed after traditional endoscopic nasal dacryocystorhinostomy were hospitalized in the Department of Otolaryngology Head and Neck Surgery department of Gansu Provincial People's Hospital from January 2010 to January 2019. Nasal lacrimal anastomosis under endoscope, intraoperative combined stent implantation, 3 months after operation, the lacrimal duct stent was removed, the patient ' s tearing symptoms were observed, the lacrimal duct was flushed to determine the lacrimal duct obstruction, and the follow-up period was 12 months. Results Twelve months of follow-up to 12 months, 14 eyes of 30 patients had no complaints of tearing, tearing, and lacrimal tract flushing; The ostomy fistula was unobstructed under nasal endoscope and the fistula was not significantly reduced. There was no complaint of tears in the eyes, tears overflowed, and the lacrimal duct was flushed, but the fistula opening was reduced.; Four eyes showed granulation hyperplasia next to the fistula, which blocked the fistula again. The overall effective rate was 87%. Conclusion Endoscopic dacryocystorhinostomy combined with stent implantation is an effective method for the treatment of chronic recurrent dacryocystitis with good clinical result.
ABSTRACT
Lung transplantation is the only effective treatment of most end-stage lung diseases. Airway anastomotic complications are the main obstacles affecting the postoperative survival and quality of life of lung transplant recipients. Airway anastomotic stenosis is the most common airway anastomotic complication after lung transplantation. In recent years, improvements in the recipient selection, organ preservation, surgical techniques, postoperative intensive care management, immunosuppression, antifungal and endoscopic treatment have decreased the incidence of airway anastomotic stenosis and improved the surgical efficacy of lung transplantation and the survival of the recipients. In this article, the pathogenesis, risk factors, diagnosis and treatment of airway anastomotic stenosis after lung transplantation were reviewed, aiming to provide novel ideas for clinical research, diagnosis and treatment of airway anastomotic stenosis following lung transplantation.
ABSTRACT
Objective To evaluate the clinical efficacy of percutaneous transluminal angioplasty (PTA) combined with stent implantation in the treatment of transplant renal artery stenosis (TRAS) after renal transplantation. Methods Clinical data of 21 patients with TRAS after renal transplantation undergoing PTA combined with stent implantation were retrospectively analyzed. The incidence of TRAS in renal transplant recipients was summarized. The changes of relevant indexes in patients with TRAS were statistically compared before and after interventional treatment. Clinical prognosis of patients with TRAS was evaluated. Results The incidence of TRAS in renal transplant recipients was 4.1%(21/507). TRAS was diagnosed at postoperative 5 (4, 7) months, and 67% (14/21) of patients developed TRAS within postoperative 6 months. Compared with the values before interventional therapy, the serum creatinine level, systolic and diastolic blood pressure and peak flow velocity of transplant renal artery of patients with TRAS were significantly decreased, and the estimated glomerular filtration rate (eGFR) and interlobar arterial resistance index were significantly increased at 1 week and 1 month after interventional therapy (all P < 0.05). During postoperative follow-up after PTA combined with stent implantation, 1 patient suffered re-stenosis of the transplant renal artery, which was improved after simple balloon dilatation. One patient developed pseudoaneurysm formation at the puncture site of the right femoral artery. One patient presented with renal atrophy and loss of function due to atresia of the transplant renal artery. All the remaining 18 patients were well recovered after surgery. Conclusions PTA combined with stent implantation is the optimal treatment of TRAS after renal transplantation, which can significantly improve the function of transplant kidney and considerably prolong the survival time of transplant kidney.
ABSTRACT
Objective:To evaluate the utility of high-resolution flat detector CT (HR-FDCT) in Willis covered stent implantation.Methods:The clinical and imaging data of 23 patients with intracranial aneurysms, intracranial artery dissection or carotid-cavernous fistula treated by Willis covered stents in our hospital from June 2017 to August 2019 were retrospectively analyzed. Images were acquired using conventional FDCT and HR-FDCT; the differences of image quality for stent visualization were compared. Immediately after stent deployment, dual volume 3D fusion images were obtained from 5 s-3D-digital subtraction angiography (DSA) and HR-FDCT, and the stent expansion status was also recorded.Results:A total of 25 Willis covered stents were implanted in 23 patients with a success rate of 100%. As compared with that by FDCT, visualization of fine structures of the stent by HR-FDCT was improved, and the image quality by HR-FDCT was significantly improved as compared with that by FDCT (mean scores: 0.56±0.71 vs. 1.56±0.65, P<0.05). According to the reconstruction of 3D fusion images obtained from 3D-DSA combined with HR-FDCT, one stent was found to have poor apposition (the distal of the stent with kinking) without vascular rupture and internal leakage, and the other 24 stents were found to have good apposition. Conclusions:HR-FDCT could better display Willis covered stent details and afford improved image quality, which instructs surgeons to adopt appropriate treatment strategy. This novel HR-FDCT has great application potential in Willis covered stent implantation.
ABSTRACT
Objective:To investigate the changes of mean venous sinus pressure (MVP) and trans-stenosis pressure gradient in patients with idiopathic intracranial hypertension (IIH) under awake setting and general anesthesia.Methods:Thirty-eight patients with IIH accepted venous sinus stent implantation in our hospital from January 2010 to January 2020 were chosen in our study; their clinical data were analyzed retrospectively. The manometry results of these 38 patients were recorded under awake setting and general anesthesia before stenting; MVP and trans-stenosis pressure gradient were obtained and compared.Results:MVP in the superior sagittal sinus, torcular, transverse sinus and sigmoid sinus showed no significant difference between patients under awake setting and general anesthesia ( P>0.05). Mean trans-stenosis pressure gradient in patients under awake setting ([22.784±7.606] mmHg) was significantly higher as compared with that in patients under general anesthesia ([18.388±8.992] mmHg, P<0.05). Conclusion:Mean trans-stenosis pressure gradient in patients under awake setting is higher as compared with that in patients under general anesthesia, and selection for venous sinus stent implantation should be decided by trans-stenosis pressure gradient in patients under awake setting.
ABSTRACT
Superior vena cava syndrome (SVCS), which is characterized by facial edema and congestion of the head, upper extremities, and neck, is a life-threatening oncologic emergency. Although a combination of chemotherapy and radiation therapy has been considered as the standard treatment for SVCS, stent implantation to the superior vena cava (SVC) has been recently developed to alleviate edema or dyspnea caused by SVCS. On the other hand, stent implantation to the SVC requires skilled interventional cardiologists or radiologists. In general, those specialists reside in university hospitals or large hospitals in an urban area. In this case report, an 86-year-old man underwent stent implantation to a stenosed SVC in a rural area. Because the patient refused the transfer to the core, urban hospital, we invited a skilled interventional cardiologist from the core hospital and performed stent implantation to the SVC in a small, rural hospital. It is generally difficult to perform stent implantation for SVCS in a small hospital, because skilled operators in the field of interventional cardiology or radiology do not usually perform operations in smaller facilities. Our case indicates the importance of cooperation between rural generalists and urban specialists.
ABSTRACT
@#Objective To explore the influence of applying the fast-track surgery (FTS) to optimize the process in the perioperative period of cardiac intervention on the rehabilitation of patients with radial artery stenting surgery. Methods A total of 190 patients with radial artery stenting surgery in the Department of Cardiology, West China Hospital from June 2017 to May 2018 were enrolled. They were randomized into a control group (n=95) and a FTS group (n=95) by random umber table. There were 60 males and 35 females aged 35-88 (65.2±9.6) years in the control group as well as 62 males and 33 females aged 34-86 (61.5±11.3) years in the FTS group. Patients in the control group received routine perioperative care, but patients in the FTS group received individual precision interventions by applying the FTS concept to optimize the process of perioperative care, including individual care management before being admitted into hospital, during hospital, and after discharge from hospital. Duration of hospital stay, satisfaction scores, number of comorbidities after surgery, disease self-management ability, and readmission rates were compared between the two groups. Results Compared to the control group, the FTS group had significantly shorter duration of hospital stay, less comorbidities, higher satisfaction scores and disease self-management ability, and lower readmission rate to hospital (P<0.05). Conclusion Applying FTS into the perioperative period of cardiac interventions to optimize its process can help patients recover from radial artery stenting surgery, increase patients’ self-management abilities, shorten duration of hospital stay and decrease comorbidities and cardiac adverse events.
ABSTRACT
PURPOSE: The efficacy of percutaneous stent implantation for congenital heart disease (CHD) in Korea, where stent availability is limited, has not been determined. This study evaluated the acute and midterm results of stent implantation in different CHD subgroups. METHODS: Stents were implanted in 75 patients with 81 lesions: (1) pulmonary artery stenosis (PAS) group, 56 lesions in 51 patients; (2) coarctation of the aorta (CoA) group, 5 lesions in 5 patients; (3) Fontan group, 13 lesions in 12 patients; (4) ductal stent group, 3 lesions in 3 patients; and (5) other CHD group, 4 lesions in 4 patients. Mean follow-up duration was 2.1 years (0.1–4 years). Medical records were reviewed retrospectively. RESULTS: The minimum lumen diameter (MLD) in PAS and CoA increased from 5.0±1.9 mm and 8.4±1.6 mm to 10.1±3.6 mm and 12.3±2.5 mm, respectively (P<0.01). In the PAS group, pressure gradient decreased from 25.7±15.6 mmHg to 10.4±10.1 mmHg, and right ventricular to aortic pressure ratio from 0.56±0.21 to 0.46±0.19. In the CoA group, the pressure gradient decreased from 50±33 mmHg to 17±8 mmHg. In the ductal stent group, the MLD of the ductus increased from 2.3 mm to 4.3 mm and arterial oxygen saturation from 40%–70% to 90%. No deaths were associated with stent implantation. Stent migration occurred in 3 patients, but repositioning was successful in all. Stent redilation was performed successfully in 26 cases after 29±12 months. CONCLUSION: Percutaneous stent implantation was safe and effective, with acceptable short and mid-term outcomes in Korean CHD patients.

Objective To study the efficacy of percutaneous transhepatic cholangiodrainage (PTCD),percutaneous gallbladder drainage,and percutaneous transhepatic biliary stent implantation for the treatment of malignant obstructive jaundice in patients who are observed to fail endoscopic drainage. Methods We retrospectively analyzed 17 patients diagnosed with obstructive jaundice between August 2015 and July 2017 who were observed to have failed endoscopic drainage. Percutaneous puncture drainage had been performed in all patients-different methods were chosen based on the type of lesion and the patient's intraoperative condition. Among these patients, 9 underwent percutaneous transhepatic biliary stent implantation (53％),5 underwent PTCD (29％),and 3 underwent percutaneous gallbladder drainage (18％). The serum levels of total bilirubin (TBIL) and alanine aminotransferase (ALT) were assessed a day preoperatively and a week postoperatively. The postoperative decrease (or drop) in the serum TBIL and ALT levels was used as a parameter to assess the efficacy of treatment. Patients were divided into a stent and a tube group. The therapeutic effects were compared between the groups in terms of the drop in the serum TBIL and ALT levels and the survival time of patients. Results The postoperative serum TBIL and ALT levels were significantly decreased in all patients (P < 0. 05). No statistically significant difference was observed between the stent and the tube group in terms of the decrease in serum TBIL and ALT levels (P > 0. 05). However,a statistically significant difference was observed between the stent and the tube group in terms of the survival time of patients (P < 0. 05). Conclusion Percutaneous puncture is an effective treatment modality to manage malignant obstructive jaundice in patients who fail endoscopic drainage. Compared to tube drainage,stent placement can prolong patient survival time. Regarding the decrease in serum TBIL and ALT levels,we conclude that stent implantation is not significantly better than tube drainage.
ABSTRACT
Objective To investigate the clinical effect of endovascular stent implantation and medical treatment in the treatment of symptomatic vertebral artery stenosis. Methods Eighty patients with symptomatic vertebral artery stenosis admitted from January 2013 to May 2015 in the Department of Neurology of Wuhan Puren Hospital were selected. The patients were randomly divided into the observation group and the control group,with 40 cases in each group. The control group was given aspirin enteric?coated tablets 100 mg/ time,1 time /d,clopidogrel bisulfate bablets 75 mg/ time,1 time /d,atorvastatin calcium 10 mg/ time,1 time/d. The observation group was treated with intravascular stent implantation. After 1 years of follow?up, the degree of vascular stenosis,the occurrence of ischemic cerebrovascular time and the clinical effect of the two groups were compared. Results (1) The stenosis degree of the observation group and the control group before treatment was (72. 81±11. 99)％ and (68. 31±12. 35)％ respectively,after treatment,it was (24. 58±1. 24)％ and (56. 01 ±3. 30)％ respectively. There was no significant difference between the two groups before treatment (t=0. 121,P>0. 05). After treatment,vascular stenosis degree in two groups were significantly improved,compared with that before treatment,the differences were statistically significant (t=0. 790,P<0. 05; t=0. 457,P<0. 05); the degree of vascular stenosis after treatment in the observation group was significantly lower than that in the control group ( t=0. 842,P<0. 05);( 2) during follow?up,the total occurrence rate of ischemic cerebrovascular events in the observation group was 17. 5％ (7/40),compared to 37. 5％ (15/40) in the control group,the difference between the two groups was statistically significant (χ2=4. 065,P<0. 05) . ( 3) At 1 years of follow?up,the total effective rate of the observation group was 97. 5％ ( 39/40) ,while that of the control group was 60％ ( 24/40) , and the difference between the two groups was statistically significant ( P=0. 017) . Conclusion Endovascular stent implantation can effectively improve the clinical efficacy of symptomatic vertebral artery, reduce the incidence of ischemic cerebrovascular time,and improve the degree of vascular stenosis.
ABSTRACT
Objective To investigate the effect of aspirin and ticagrelor or clopidogrel anticoagulant therapy on platelet aggregation,endothelial function and levels of inflammatory mediators in patients with acute coro-nary syndrome(ACS)after coronary stent implantation(PCI).Methods 100 cases of patients with ACS who underwent coronary stent implantation in our hospital from April 2014 to May 2016 were enrolled in the stud-y.The patients were randomly divided into the observation group and the control group by random number ta-ble method,50 cases in each group.The observation group were treated with aspirin and ticagrelor anticoagu-lant therapy after operation,while the control group were treated with aspirin and clopidogrel anticoagulant therapy.All patients were followed up for 1 year.The platelet aggregation rate within 1 year of medication, levels of serum endothelin-1(ET-1),nitric oxide(NO),plasminogen activator inhibitor-1(PAI-1),high-sen-sitivity C reactive protein(hs-CRP),interleukin-6(IL-6)and soluble CD40 ligand(sCD40L)were compared between the two groups.The outcome events and adverse reactions were recorded.Results 1 month,6 months and 1 year after treatment,the platelet aggregation rates in the observation group were lower than those in the control group(P<0.05).After treatment,levels of serum ET-1,PAI-1,hs-CRP,IL-6 and sCD40L were sig-nificantly lower in the observation group than the control group(P<0.05),while NO level was higher than the control group(P<0.05).The incidence rates of outcome events and adverse reactions in the observation group were slightly lower than those in the control group(6.00% and 8.00% vs.10.00% and 10.00%,P>0.05).Conclusion The effect of aspirin combined with ticagrelor anticoagulant therapy is better than that of aspirin combined with clopidogrel anticoagulant therapy in patients with ACS after PCI.The former can signif-icantly improve platelet aggregation,endothelial function and levels of inflammatory mediators,and it is safe and reliable.
ABSTRACT
Objective To evaluate the clinical effect of endovascular therapy with covered stent in treating aortoiliac occlusive disease. Methods The clinical data of 20 patients with aortoiliac occlusive disease, who received endovascular therapy with covered stent during the period from January 2014 to December 2016, were collected. According to Rutherford standard of clinical symptom classification, gradeⅢ, grade Ⅳ and grade V were seen in 9, 7 and 4 patients respectively. Based on the Trans-Atlantic Society Coalition (TASC) treatment guidelines Ⅱ classification, B type, C type and D type were observed in 4, 7 and 9 patients respectively. The postoperative primary patency and secondary patency of the stent as well as the clinical efficacy were analyzed. Results Endovascular treatment was successfully accomplished in all 20 patients. After the treatment, the clinical symptoms were significantly relieved. Two patients developed complications (10％). One patient developed thrombus at the distal end of stent, which was improved after thrombolytic therapy. Another patient developed hematoma at puncture site, which was absorbed after conservative therapy. No perioperative death occurred. The patients were followed up for 5-37 months, with a mean of (17±10) months. The primary patency rate was 95％ and the secondary patency rate was 100％. Conclusion For the treatment of aortoiliac occlusive disease, endovascular therapy with covered stent has excellent clinical efficacy.
ABSTRACT
Objective To evaluate the clinical effect of endovascular interventional therapy in treating Cockett syndrome associated with deep vein thrombosis (DVT) of left lower extremity.Methods The clinical data of a total of 256 patients with Cockett syndrome complicated by DVT of left lower extremity,who were admitted to authors' hospital during the period from January 2011 to January 2015,were retrospectively analyzed.The patients were treated with catheter-directed thrombolysis,balloon dilatation of the occluded or narrowed venous segment,and/or stent implantation.The circumference differences of the affected limbs before and after treatment and the long-term patency rates were compared.Results Of the 256 patients with Cockett syndrome complicated by DVT of left lower extremity,complete dissolution of thrombus was achieved in 232 (90.6％) and partial dissolution of thrombus in 24 (9.4％).The circumference difference of thigh and calf was (7.12±2.15) and (4.57±2.81) cm respectively before and after treatment.Iliac vein reconstruction was carried out in 206 patients,among them simple balloon dilatation was employed in 46 and balloon dilatation together with stent implantation was adopted in 160.The patients were followed up for 9-24 months with a mean of 15 months.In simple balloon dilatation group,3 patients lost touch with the authors during the following-up period,26 patients (60.5％) developed iliac vein occlusion and post-embolization syndrome occurred in 21 patients (48.8％).In balloon dilatation plus stent implantation group,11 patients lost touch with the authors during the following-up period,stenosis or occlusion of the stent was seen in 13 patients (8.7％),post-embolization syndrome was observed in 15 patients (10.1％).The differences in vascular stenosis or occlusion and in the occurrence of post-embolization syndrome between the two groups were statistically significant (P＜0.001).Conclusion For the treatment of Cockett syndrome complicated by DVT of left lower extremity,catheter-directed thrombolysis and balloon dilatation combined with stent implantation carry definite clinical curative effect.
