ABSTRACT
Objective:To explore the predictors and reasons for restenosis in patients with Takayasu′s arteritis(TA) involved renal artery after plain old balloon angioplasty(POBA).Methods:The clinical data of 47 TA patients (47) with renal artery admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were analyzed, including 12 man and 35 female. The age ranged from 21 to 43 years old, with an average of (28.52±10.78) years old. All patient were diagnosed as TA and underwent POBA. The patients were divided into restenosis group ( n=18) and non-restenosis group ( n=29). The patients were followed up at 1, 3, and 6 months after surgery, and after 6 months, the patients were followed up every 6 months. All patients were followed up from 36 to 108 months.The basic clinical data of the two groups were compared, and the length of stent and residual stenosis were also compared. Measurement data were expressed as ( ± s), and t-test was used for comparison between groups. Counting data were expressed as the number of cases and percentage, and comparison between groups was analyzed using the chi-square test. Multivariate Logistic regression model was used to analyze the independent risk factors of restenosis after balloon dilation, and the OR value and 95% confidence interval were calculated. Logistic regression model was used to analyze the independent risk factors for restenosis after balloon dilation. Results:All patients received POBA and operation was successfully. Restenosis was found in 18 patients, and 29 patients remained normal during the follow-up. The primary patency rate was 61.7%. Multivariate Logistic regression analysis showed that HDL-C and lesion length were the influencing factors of restenosis after POBA in TA of renal artery. The serum HDL-C level was significantly lower and the lesion was significantly longer in restenosis group than in non-restenosis group ( P<0.05). The proportion of residual stenosis>20% was higher in restenosis group than in non-restenosis group ( P>0.05). Conclusion:Serum HDL-C level, lesion length may be may be independent influencing factors of restenosis after plain old balloon angioplasty in TA of the renal artery restenosis.

ABSTRACT
This paper introduces several major methods of surgical treatment of ischemic diabetic foot artery occlusion lesions, including open bypass procedure, endovascular treatment and angiogenesis therapy, details the advantages and disadvantages of each surgical technique, and emphasizes the necessity of selecting appropriate surgical treatment options to treat patients with diabetic foot lower limb artery occlusive ischemia during different situations.
ABSTRACT
Objective:To explore the feasibility and efficacy of subpatellar artery balloon molding in the treatment of diabetic foot ulcer caused by arterial ischemia.Methods:The clinical data of patients with diabetic foot ulcer caused by subpatellar artery disease treated in Xuanwu Hospital of Capital Medical University from December 2020 to April 2022 were retrospectively analyzed. Among them, 29 patients received medical balloon dilatation (drug balloon group) and 30 patients received balloon dilatation alone (simple balloon group). The improvement of lower limb ischemia at 3 and 6 months after surgery was analyzed in the two groups. The observation indicators included case-fatality rate, limb preservation rate, ulcer healing, Rutherford grading and pain score.Results:There was no significant difference in preoperative Rutherford grading between the two groups ( P>0.05). Three and six months after operation, the Rutherford grading in both groups was significantly improved compared with that before surgery (all P<0.05), and there was no statistical significance between the two groups ( P>0.05). There was no significant difference in preoperative pain scores between the two groups ( P>0.05). The pain scores of both groups were significantly decreased 3 and 6 months after surgery ( P<0.05), and there was no statistical significance between the two groups ( P>0.05). Three and six months after surgery, the wound ulcer healing rate in the drug balloon group was higher than that in the simple balloon group [51.7%(15/29) vs 43.3%(13/30), P=0.519; 86.2%(25/29) vs 50.0%(15/30), P=0.002]. There was no death or amputation in the two groups 3 and 6 months after surgery. Conclusions:Balloon dilatation can improve severe limb ischemia of diabetic foot. Compared with balloon dilatation alone, drug balloon dilatation is more beneficial to the healing of ulcer wounds in diabetic limb ischemia patients.
ABSTRACT
With the increasing incidence of diabetes in China, the related complications also show a trend of " spreading" , and diabetes foot (DF) is one of the most serious complications of diabetes. The arterial disease of lower limbs in patients with DF are relatively complex, and the recovery of arterial blood supply of lower limbs is the key to improve the quality of life and limb preservation rate of patients with DF. At present, endovascular therapy is the first choice for the treatment of diabetic foot ischemic lesions in China because of its minimally invasive and quick recovery. In order to treat DF in a better and more standardized way and make patients benefit more, this paper summarized the strategies of endovascular treatment for DF ischemia by combining the objectives of DF treatment and the principles of endovascular treatment.
ABSTRACT
Objective:To investigate the clinical characteristics and surgical treatment experience of carotid body tumor (CBT).Methods:The clinical data of 12 patients with CBT admitted to the Department of Vascular Surgery, Xuanwu Hospital, Capital Medical University from March 2013 to August 2020 were analyzed retrospectively. Among them, there were 6 males and 6 females, aged 31-83 years, with a median age of 57 years. Among the 12 patients, 2 patients were not treated surgically. The body mass index (BMI), tumor side, maximum diameter of tumor, and tumor classification, operation time, intraoperative bleeding volume, postoperative drainage volume and time, postoperative hospital stay and postoperative complications of patients undergoing surgery were recorded.Results:BMI of the 12 patients was 17.19-29.07 kg/m 2, with an average of (24.05±3.95) kg/m 2. Among the 12 patients, there were 4 tumors on the left side, 6 tumors on the right side and 2 patients had bilateral tumors. The maximum diameter of the tumor was 1.7-8.7 cm, with an average of (4.05 ± 1.89) cm. Among the 2 patients with bilateral tumors, 1 patient underwent staged resection within 9 months and 1 patient only removed the larger tumor. A total of 10 patients underwent surgical resection. All excised tumors were confirmed histopathologically to be paraganglioma. The average operation time and the amount of bleeding was(164.73 ± 74.39)min and 341.82 mL respectively. The drainage time was 1-3 d, with an average of (1.73 ± 0.65) d. The cumulative drainage volume was 22-237 mL, with an average of (77.18 ± 57.47) mL. Classification of 11 surgically resected tumors: 3 patients (3/11, 27.3%) were Shamblin Ⅰ, 7 patients (7/11, 63.6%) were Shamblin Ⅱ and 1 patient (1/11, 9.1%) were Shamblin Ⅲ. There were 1 patient of hematoma and 1 patient of acute cerebral infarction after operation. One patient with decrease in muscle strength of right limb, other surgical patients complained no complications such as stroke and cranial nerve injury when discharged. Patients undergoing surgery were hospitalized for 8-20 days, with an average of (13.36 ± 3.61) d. Conclusions:CBT is a rare paraganglioma in clinic. Surgical resection is an effective method to treat CBT. Careful operation should be carried out to avoid serious complications such as wound hematoma, cranial nerve injury and ischemic stroke.
ABSTRACT
Objective:To investigate the clinical characteristics as well as short-term and long-term prognostic factors of patients with Stanford type B aortic dissection (TBAD) with hypertension.Methods:Patients with TBAD who received thoracic endovascular aortic repair (TEVAR) admitted to Xiangyang Central Hospital from January 2014 to December 2018 were enrolled. The baseline data of patients admitted to the hospital were collected through the case management system, including gender, age, underlying diseases (hypertension, diabetes, coronary heart disease), smoking history, drinking history, duration of pain, vital signs at admission [heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP)], laboratory results [white blood cell count (WBC), platelet count (PLT), neutrophil/lymphocyte ratio (NLR), serum creatinine (SCr), C-reactive protein (CRP), D-dimer, ascending aorta diameter], etc. The clinical characteristics of TBAD patients with hypertension were analyzed. Logistic regression model and Cox proportional risk model were used to analyze the impact of hypertension on the short-term and long-term all-cause deaths after TEVAR in TBAD patients.Results:Among 227 TBAD patients, 160 cases (70.5%) were complicated with hypertension, while 67 cases (29.5%) were not. The average age, the proportion of diabetes and coronary heart disease, and the level of SBP, DBP and SCr at admission of TBAD patients with hypertension were higher than those of TBAD without hypertension [age (years old): 53.1±11.9 vs. 42.8±14.1, combined with diabetes: 8.8% vs. 1.5%, combined with coronary heart disease: 6.3% vs. 0%, SBP (mmHg, 1 mmHg = 0.133 kPa): 147.9±18.1 vs. 136.9±15.2, DBP (mmHg): 93.9±11.9 vs. 89.1±13.8, SCr (μmol/L): 97.8±25.4 vs. 89.8±23.6, all P < 0.05]. The short-term mortality of TBAD with hypertension group was significantly higher than that of TBAD without hypertension group [6.3% (10/160) vs. 0% (0/67), χ2 = 4.386, P = 0.036]. 227 patients with TBAD were followed up for 3-66 months, with a median follow-up time of 25 months. There was no significant difference in long-term mortality between TBAD patients with and without hypertensive during discharge follow-up [13.1% (21/160) vs. 9.0% (6/67), χ2 = 0.784, P = 0.376]. Further multivariate Logistic regression analysis and Cox regression analysis did not indicate that hypertension was an independent risk factor for short-term and long-term death in TBAD patients [odds ratio ( OR) and 95% confidence interval (95% CI) were 13.477 (0.541-330.215), 1.012 (0.990-1.035), both P > 0.05]. Age and HR were independent risk factors for the short-term mortality of TBAD patients [ OR and 95% CI were 15.287 (1.051-226.415), 0.026 (0.002-0.840), both P < 0.05]. Age, PLT and D-dimer were independent risk factors for the long-term mortality of TBAD patients [ OR and 95% CI were 1.808 (1.205-2.711), 0.555 (0.333-0.924), 1.482 (1.035-2.122), respectively, all P < 0.05]. Conclusions:The TBAD patients with hypertension have older age, high rates of diabetes or coronary heart disease. However, hypertension is not an independent risk factor for short-term and long-term mortality in TBAD patients.
ABSTRACT
The clinical data of 4 patients with peripheral vascular rupture admitted in the Hetian Regional People′s Hospital from March 2012 to October 2017 were retrospectively analyzed. The 4 patients were all males, aged 17-59 years. Among them, 2 cases caused by firearm injury, 1 case was caused by a car accident and 1 case was caused by a sharp injury; 2 cases were incompletely ruptured in femoral artery, 1 case was completely ruptured in popliteal artery, and 1 case was completely ruptured in axillary artery. All patients underwent successful reconstructive surgical procedures, and the skin temperature, skin color, and arterial pulse of the affected limb returned to normal after operation. The followed-up time was 28-95 months, with an average of 47.8 months. Blood flow in the reconstructed vessel was unobstructed. There were no complications. It is indicates that for peripheral vascular rupture if the diagnose and treatment are timely, the satisfactory results can be achieved.
ABSTRACT
Objective:To explore the method and effect of endovascular treatment to innominate artery stenosis or occlusion.Methods:The data of 11 patients with stenosis or occlusion of innominate artery from January 2014 to November 2019 at Xuanwu Hospital of Capital Medical University were collected. All patients received endovascular treatment. We summarized the changes of clinical symptoms, surgical methods, perioperative complications, stent patency, and analyzed the changes in systolic blood pressure and peak blood flow velocity on the involving side.Results:All 11 patients underwent endovascular treatment. The surgical technique success rate was 100%. All patients were followed up. The follow-up time was 4-69 months, with an average of (30.1±23.4)months. 2 patients used cerebral umbrella during the operation. 1 patient was performed ipsilateral carotid endarterectomy, 1 patient underwent contralateral carotid stent implantation, 1 patient was diagnosed as severe stenosis of the innominate artery and left common carotid artery, and an innominate artery stent implantation was performed at one stage, left common carotid artery stent implantation was performed after half a year. We done operation from the femoral artery puncture approach (6 patients), brachial artery puncture approach (2 patients), axillary artery and femoral artery puncture approach (1 patients), and right common carotid artery and the femoral artery puncture approach (2 patients). 3 patients had in-stent restenosis at 6, 7and 12 months after stenting, respectively. 1 patient underwent balloon dilatation, and 2 patients underwent re-stent implantation. We have not do further intervention to 1 case of in-stent occlusion occurred 14 months after the stenting, for the clinical symptoms did not improve significantly. The clinical re-intervention rate in this group was 3/11, and the primary patency rate was 7/11. The secondary patency rate was 10/11. The symptoms of 10 patients were relieved and the weakness of right upper extremity was not significantly changed in 1 patient. No puncture point complications occurred in all patients, and no cerebral infarction occurred during the perioperative period. There were statistically significant differences in systolic blood pressure, blood pressure difference and peak blood flow velocity before and after the operation ( P<0.05). Conclusions:Endovascular treatment of innominate arterial stenosis or occlusion was safe and effective, and the appropriate surgical approach and plan should be selected according to the lesion characteristics and the whole body conditions.
ABSTRACT
About 25%-40% of ischemic stroke is in the posterior circulation, in which 20% of posterior circulation stroke is caused by vertebral artery stenosis. Patients with symptomatic vertebral artery stenosis have a high risk of recurrent stroke. At present, the treatments of vertebral artery stenosis include medication, open surgery and interventional therapy. In this paper, the endovascular treatment of vertebral artery stenosis is reviewed, especially the progress of endovascular treatment is expounded, in order to promote the development of its treatment.

ABSTRACT
Re-use of contrast agent during endovascular treatment in patients with contrast agent allergy may lead to severe allergic reaction. For patients with localized stenosis of external iliac artery, endovascular therapy (stenting) is the first choice. Whether patients with severe iliac artery stenosis with contrast allergy can be treated with endovascular therapy is unknowed. A case of iliac artery stenting without contrast agent is reported in this paper. The successful implementation of this operation requires adequate preoperative and intraoperative preparation, and the accurate determination of the stenosis site and the presence or absence of residual stenosis during the operation.
