目的 探讨Trivex旋切术治疗下肢血栓性浅表静脉炎的临床疗效。方法 回顾性分析67例下肢血栓性浅表静脉炎病例的临床资料。患者术前给予丹参治疗、下肢静脉造影等术前准备； 然后行大隐静脉主干内膜剥脱、用Trivex旋切系统剖吸曲张静脉和静脉丛内的血栓； 术后给予低分子肝素抗凝、早期下床活动等处理。结果 全部患者的手术均顺利，术中及术后无肺栓塞发生。术后2例切口Ⅱ期愈合， 65例切口Ⅰ期愈合。所有病例术后3d均出院，住院时间（5±1） d。15例术后患肢有瘀斑者随访2周均消失； 7例出现内踝部麻木感，随访6个月消失； 本组患者均获随访6个月，未见复发者。结论 下肢血栓性静脉炎早期行以Trivex旋切术为主的综合治疗，其临床疗效好、住院时间短、创伤小及美容效果好，并可有效防止病情反复、深静脉血栓及肺栓塞的发生，是治疗下肢血栓性静脉炎的有效手段。
ObjectiveThis study was aimed to evaluate the clinical efficacy of mechanical thrombectomy using the AngioJet System for the treatment of lower extremity acute arterial embolism and thrombosis.MethodsThe clinical data of 20 patients with acute lower extremity arterial embolism and thrombosis admitted to the Department of Vascular Surgery in the People’s Hospital in Gansu Province where the author worked from September 2016 to March 2017, were retrospectively analyzed. All patients were treated with the AngioJet mechanical thrombectomy system. Clinical data of the patients were retrospectively collected. The clinical efficacy of AngioJet mechanical thrombectomy wasanalyzed.ResultsEighteen (90.0%) of the 20 patients successfully completed the mechanical thrombectomy by using the AngioJet System. The mean time for hospital stay and operation was (4.2±1.4) d and (1.3±0.4) h, respectively. The average doses of urokinase and heparin during operation were (35.80±12.30) ×104 U and (45.10±8.30) mg, respectively. Two patients received a complementary treatment of incision for removing the thrombus. Two patients received catheter-directed thrombolysis after the mechanical thrombectomy, 5 patients received bare-metal stent implantation after balloon expansion. Clinical success was in 16 cases. According to the Cooley standard, 10 patients were in excellent condition,6 in good condition, 2 in fair condition, and 2 in poor condition. There were 2 cases of distal arterial embolization,2 cases of antecardial discomfort of bradycardia, and 4 cases of bleeding at the puncture point, but no serious bleeding complications such as gastrointestinal and intracranial hemorrhage occurred. A total of 16 patients presented myoglobinuria during and after operation. All patients were followed up for 6–12 months. The results of ultrasound examination showed that the artery was patency in 15 cases. One patient died of myocardial infarction in 9 months after surgery,2 patients developed lower extremity ischemia symptoms again after surgery, and 2 patients had lower extremity ulcer caused by lower extremity ischemia symptoms. During the follow-up period, no lower limb necrosis, amputation, and death occurred in the remaining patients.ConclusionsThe AngioJet mechanical thrombectomy system is safe and effective. Combined with the use of catheter-directed thrombolysis and stent implantation, the AngioJet mechanical thrombectomy could lead to quick recovery of the perfusion of the lower extremity and improve the limb salvage rates, exhibiting excellent clinical value.
ObjectiveTo evaluate the efficacy and safety of intracavitary treatment for iliac vein compression syndrome（IVCS）with acute lower extremity deep venous thrombosis (DVT).MethodsThe clinical data of 57 patients with IVCS and lower extremity DVT, who undergoing with stent implantation, balloon expansion and Angiojet rheolytic thrombectomy from June 2015 to June 2018, were retrospectively analyzed. The effect of treatment was evaluated by the changes of thigh circumference difference between the affected side and the healthy side, and the thrombosis clearance rate in the operating. In addition, the incidence of post-thrombotic syndrome (PTS) and stent patency rate were analyzed after long-term follow-up based on the change of Villaita scale score and ultrasound examination of lower extremity veins.ResultsThe success rate of surgical technique was 100%, and there was no pulmonary embolism during operating and postoperative. Lower extremity deep vein thrombosis clearance levels Ⅲ 48 cases (84.2%), Ⅱ 9 cases (15.8%), the changes of thigh circumference difference between the affected side and the healthy side from preoperative (5.8±1.7) cm to (3.7±1.0) cm. One year follow-up after operation, the primary patency rate of stent was 86.0% and PTS occurred in 8 patients (14.0%).ConclusionStent implantation, balloon expansion and Angiojet rheolytic thrombectomy for IVCS with acute lower extremity DVT is a safe, effective with low incidence of complications and efficient thrombus clearance.
The incidence of venous thromboembolism (VTE) is relatively high in the elderly population, and the disability, mortality, and medical expenses caused by VTE are also high. However, in a large number of randomized controlled and non-randomized controlled studies related to VTE, sufficient attention has not been paid to the elderly population with multiple underlying diseases. Therefore, the vast majority of research results recommended by VTE guidelines come from younger patients and healthy elderly people, at the same time, most relevant VTE prevention and treatment guidelines or consensus are formulated for hospitalized patients, and for non-hospital elderly populations such as home and elderly care institutions that truly need attention and risk of VTE, their recommended opinions are uncertain. In this context, the Peripheral Vascular Disease Management Branch of the Chinese Geriatrics Society has developed a consensus among Chinese experts on the prevention and treatment of VET in the elderly, based on evidence-based evidence such as domestic and foreign guidelines and relevant research.
