Objective:To evaluate the therapeutic effect of excimer laser ablation (ELA) in the treatment of lower extremity arterial ischemic diseases.Methods:The clinical data of 44 patients with lower extremity ischemic diseases treated with ELA in the People′s Hospital of Xinjiang Uygur Autonomous Region from December 2020 to April 2021 were analyzed retrospectively. Among the 44 patients, there were 29 patients in lower extremity arteriosclerosis obliterans (ASO), including 3 patients with femoral artery stent occlusion. 8 patients of diabetes foot (DF) and 7 patients of thromboangiitis obliterans (TAO). Observation indicators include target vascular patency rate, amputation rate, vascular reintervention rate and mortality rate. The measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for inter-group comparison, and paired sample t-test was used for intra-group comparison. The Chi-square test was used for comparison between count data. Results:The success rate of operation was 100% in 44 patients. The rate of major amputation in ASO group was 10.3%, while the other two groups had a major amputation rate of 0. The minor amputation rates of the three groups were 6.9%, 25.0% and 28.6%, respectively. The vascular reintervention rate was 10.3% in ASO group, 12.5% in DF group and 0 in TAO group. The 1-year mortality rate in the ASO group was 10.3%, while the other two groups had a mortality rate of 0. The 2-year mortality rate of the three group were 31.0%, 12.5% and 0, respectively.Conclusion:For the treatment of lower extremity arterial ischemic diseases, ELA is safe and effective, but the curative effect need to further clarify by large sample and long-term clinical follow-up observation.

OBJECTIVES: To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery. METHODS: From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed. RESULTS: All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred. CONCLUSIONS The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.

The internal iliac artery originating from the common iliac artery is an important branch, and communicating with the branches of the abdominal aorta, such as lumbar artery and sacral median artery, forming rich collateral circulation and nourishing the blood supply of gluteal muscle and pelvic floor viscera. Surgical intervention is recommended when the maximum diameter of internal iliac artery aneurysms>2 cm. A variety of treatment modalities are available, particularly, endovascular technique has been successfully applied in the clinical treatment of internal iliac artery aneurysms, which can significantly improve the cure and reduce complications and deaths. This article reviews the previous literature and summarizes the progress of internal iliac artery aneurysms treatment.

Objective:To explore the clinical efficacy of excimer laser atherectomy (ELA) in the treatment of diabetic foot with infrapopliteal arteriopathy.Methods:The clinical data of 36 patients (40 limbs) with diabetic foot complicated with inferior knee artery disease treated by ELA in Xinjiang Uygur Autonomous Region People′s Hospital from December 2019 to May 2021 were analyzed retrospectively. The success rate of ELA in the treatment of diabetic inferior genicular artery disease, ankle-brachial index (ABI), limb salvage rate and Visual Analogue Scale (VAS) score at 3 days and 3 and 6 months after operation was observed.Results:All the 36 patients were operated successfully, including 2 cases of flow-limiting dissection, 2 cases of arterial embolism and 1 case of hematoma at the puncture point. The ABI of patients 3, 6 months after operation was significantly higher than that before operation (all P<0.05), and the VAS score 3, 6 months after operation was significantly lower than that before operation (all P<0.05). The rate of limb (toe) salvage were 92.5%(37/40), 82.5%(33/40) at 3 d, 3 months and 77.5%(31/40) at 6 months after operation. Conclusions:ELA is safe and effective in the treatment of diabetic foot infrapopliteal arteriopathy, and the recent efficacy is fair.

Objective:To analyze locoregional recurrence (LRR) pattern of patients with pT 1-2N 1 breast cancer after modified radical mastectomy, with and without adjuvant radiotherapy (RT). Methods:A total of 5442 eligible patients with breast cancer from 12 Chinese centers were included. The LRR sites and the effect of RT at different sites on recurrence in patients with and without RT were analyzed. The Kaplan-Meier method was used to calculate the cumulative LRR rate, and the difference was compared by the log-rank test.Results:With a median follow-up time of 63.8 months for the entire cohort, 395 patients developed LRR. The chest wall and supraclavicular fossa were the most common LRR sites, regardless of RT or molecular subtypes. The 5-year chest wall recurrence rates for patients with and without chest wall irradiation were 2.5% and 3.8%( P=0.003); the 5-year supraclavicular lymph nodal recurrence rates for patients with and without supraclavicular fossa irradiation were 1.3% and 4.1%( P<0.001); the 5-year axillary recurrence-free rates for patients with and without axillary irradiation were 0.8% and 1.5%( HR=0.31, 95% CI: 0.04-2.23, P=0.219); and the 5-year internal mammary nodal recurrence-free rates for patients with and without internal mammary nodal irradiation were 0.8% and 1.5%( HR=0.45, 95% CI: 0.11-1.90, P=0.268). Conclusions:The chest wall and supraclavicular fossa are the most common LRR sites of patients with pT 1-2N 1 breast cancer after modified radical mastectomy, which is not affected by adjuvant RT or molecular subtypes. The chest wall and supraclavicular fossa irradiation significantly reduce the risk of recurrence in the corresponding area. However, axillary and internal mammary nodal irradiation has no impact on the risk of recurrence in the corresponding area.

Objective:To explore the strategies for the treatment of difficult iliac artery approach in endovascular repair of abdominal aortic aneurysm.Methods:The clinical data of 275 patients with abdominal aortic aneurysm who underwent endovascular surgery at the Department of Vascular Surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from March 2010 to March 2019 were retrospectively analyzed, and the general clinical data such as age, gender, and comorbidities of the patients were recorded. The resource index was to carry out corresponding measures to perform surgery for patients with difficult access, analyze the incidence of the type of difficult access, treatment measures and effects.Results:Two hundred and seventy-five patients underwent endovascular repair, 78 of them (28.3%) had difficulty in accessing the iliac artery, including 29 cases (10.5%) with mild iliac artery stenosis, 7 cases (2.54%) with severe stenosis, and 3 cases with occlusion ( 1.09%), 39 cases (14.2%) were twisted. For patients with vascular twist, super-hard guide wire was used to correct iliac artery angulation. For patients with iliac artery stenosis, balloon dilation was performed. For severe stenosis, the artificial blood vessel was passed through the lateral peritoneum. After road transplantation, stent placement and other treatments were successfully performed endovascular repair.Conclusions:Pathway vascular disease can cause difficulties in endovascular treatment of abdominal aortic aneurysms. Endovascular repair can be successfully performed after corresponding treatments according to different difficulties, and the long-term patency rate is good.

Objective:To investigate and compare the efficacy and safety of percutaneous mechanical thrombectomy (PMT) combined with catheter directed thrombolysis and catheter directed thrombolysis alone in the treatment of acute lower extremity deep venous thrombosis.Methods:Retrospective analysis of clinical data of 69 patients with acute lower extremity deep venous thrombosis who met the inclusion criteria of this study from January 2018 to December 2018 in department of vascular surgery, People′s Hospital of Xinjiang Uygur Autonomous Region was performed. There were 35 males and 34 females, with an average age of 59 years and an age rang of 20 to 80 years. Patients were divided into PMT combined catheter directed thrombolysis treated group ( n=38) and catheter directed thrombolysis treated group ( n=31) according to different methods of intra-luminal thrombolysis. The thrombolysis time, dosage of urokinase, thrombotic clearance rate, perimeter difference of suffered limb, and total number of adverse events during perioperative period between two groups were recorded. At 1 month, 3 months, and 6 months after discharge, patients underwent an ultrasonographic examination of lower extremity vessels to check and evaluate residual thrombolysis and thrombosis recurrence by outpatient review. The quantitative data in the two groups were expressed as mean±standard deviation( Mean± SD), t test was used for comparison between groups. Enumeration data in the two groups were expressed as percentage (%) and χ2 test was used for comparison between groups. Results:The thrombolysis time of PMT combined catheter directed thrombolysis treated group and catheter directed thrombolysis treated group were (3.7±2.1) d and (5.2±2.1) d, respectively. The differences between the two groups were statistically significant ( P=0.005). The dosage of urokinase were respectively (225.0±122.3)×10 4 units and (315.8±108.6)×10 4 units, the differences were statistically significant ( P=0.001). PMTⅠ, Ⅱ, Ⅲ thrombus clearance rate in patients with PMT combined catheter directed thrombolysis treated group were 18.4% (7/38), 73.7% (28/38), 7.9% (3/38), while 16.1% (5/31), 77.4% (24/31), 6.5% (2/31) were observed in patients with catheter directed thrombolysis treated group, with no statistically significant difference between the two groups ( P= 0.803, P=0.720, P=0.818). After a period of 48h thrombolytic therapy, the cross-section diameters of suffered thigh and calf were (2.16±0.87) cm and (1.38±0.66) cm in PMT combined catheter directed thrombolysis treated group respectively. While the cross-section diameters of suffered thigh and calf were (1.21±0.59) cm and (1.02±0.49) cm in catheter directed thrombolysis treated group respectively. The differences in the cross-section diameters of suffered thigh and calf were statistically significant after a period of 48h thrombolytic therapy ( P<0.001, P=0.014). Three cases (7.89%) had occurred adverse events during perioperative period in PMT combined catheter directed thrombolysis treated group, while there were 4 cases (12.90%) in catheter directed thrombolysis treated group, with no statistically significant difference between two groups ( P=0.692). The six month follow-up rate of PMT combined with catheter directed thrombolysis treated group was 71.05%(27/38), while that of the catheter directed thrombolysis treated group was 64.52% (20/31), with no statistically significant difierence between the two groups ( P=0.532). During the six month of follow-up, the recurrence rate of thrombus in PMT combined catheter directed thrombolysis treated group (3/27, 11.11%) was lower than those patients in catheter directed thrombolysis treated group (3/20, 15.00%), with no statistically significant difference between the two groups ( P=0.693). Conclusions:Compared with catheter directed thrombolysis treated group, PMT combined catheter directed thrombolysis treated group has a similar clinical efficacy for treatment of acute lower extremity deep venous thrombosis. PMT combined catheter directed thrombolysis treated group has advantages of reducing dosage of urokinase, shortening duration of thrombolysis time and relieving the swelling of suffered limb in a short time rather than catheter directed thrombolysis treated group. It shows a great result in the short term follow up.

Objective: To explore the clinical application indications, filter selection and filter removal techniques of inferior vena cava filter. Methods: Retrospective analysis of the clinical data of 108 cases of inferior vena cava filter implantation in the Department of Vascular Surgery, People's Hospital of Xinjiang Uygur Autonomous Region from January 2018 to February 2019 was performed. One hundred and eight patients with inferior vena cava filter were eligible for filter placement, including 50 males and 58 females; the average age was 59 years, and the age ranged from 23 to 90 years. Different types of inferior vena cava filters were selected according to the patient's condition, the location of the thrombus, the type of surgery and the prognosis of the disease. In this study, lower extremity vascular ultrasound was performed by the outpatient in 2 weeks after the filter placement, 1 month after the operation, 2 months after the operation, and 3 months after the operation. The inferior vena cava filter was recovered by a catcher. Loop technology, Loop and biopsy forceps were used for patients with difficult filter recovery. After removal of the filter, the angiography confirmed the integrity of the inferior vena cava wall. Observe whether the filter was completed, deformed, broken and whether there was thrombus in the filter. Results: The removal of inferior vena cava filter was performed in patients with no free floating thrombus or fresh thrombus in popliteal, femoral, iliac and inferior vena cava confirmed by ultrasound. In this group, 108 patients with inferior vena cava filter implantation included 11 patients anticoagulant contraindications, 11 patients with pulmonary embolism, 5 patients with floating thrombosis in iliac vein, femoral vein or inferior vena cava, 35 patients with acute deep venous thrombosis of lower extremity received catheter-directed thrombolysis or percutaneous mechanical thrombectomy, 46 patients with abdominal, pelvic or lower extremity surgery for acute deep venous thrombosis of lower extremity and high risk factors of pulmonary embolism. One hundred and three patients received retrievable inferior vena cava filters and 5 patients received temporary inferior vena cava filters. Ninety-two patients were followed up successfully in this group. In 74 patients, the filter trap was recovered using a catcher, and the inferior vena cava filter of 12 patients were successfully removed by Loop technology and Loop with biopsy forceps.The success rate of the filter removal was 93.5%. After removal of the filter, angiography of inferior vena cava showed smooth wall, blood flow patency and no extravasation of contrast agent. The removal filters have normal shape, no fracture and no deformation. Conclusions Operators should strictly observe the indication of inferior vena cava filter placement, master a variety of filter removal methods to improve the success rate of filter removal and maximize the benefit of patients with inferior vena cava filter implantation.
