ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
The incidence of deep vein thrombosis has increased year by year in the world, and it has become one of the serious diseases that threaten human life. In severe cases, it can lead to fatal pulmonary embolism. The pathogenesis of deep vein thrombosis is the result of the interaction of multiple genetic environmental factors. Therefore, regulation of gene expression by modification of DNA and histones may help to further reveal the pathogenesis of deep vein thrombosis, and reactivation or silencing of some genes that are inhibited or overexpressed by aberrant methylation may be a major therapeutic target for deep vein thrombosis. The author reviews the current status of DNA methylation studies related to deep vein thrombosis.
