目的研究置管溶栓联合球囊扩张导管碎栓治疗下肢深静脉血栓形成（DVT）的疗效及安全性。 方法回顾性分析2011年9月至2015年1月本院收治的82例急性下肢DVT患者的临床资料。将患者分成两组：A组行单纯经导管直接溶栓（CDT）治疗，共32例，其中男10例、女22例，平均年龄（56±15）岁；B组行CDT联合机械碎栓（球囊扩张导管碎栓）治疗，共50例，其中男18例、女32例，平均年龄（57±17）岁。比较2组治疗前后静脉通畅率、静脉通畅度评分、健侧和患侧下肢周径差，比较2组尿激酶用量及溶栓导管留置时间，以出血并发症、肺栓塞的发生率评价治疗的安全性。 结果2组共82例患者完成溶栓及碎栓疗程，B组较A组溶栓时间更短，A组平均9（7，12）d；B组平均5（4，7）d，2组差异有统计学意义（P<0.01）；B组较A组尿激酶用量更少，A组平均7.250（6.355，8.255）×106 U，B组平均4.925（3.715，5.810）×106 U，2组差异有统计学意义（P<0.01）；B组治疗后的静脉通畅度评分显著优于A组，A组65.0%（40.5%，86.5%），B组为100%（90%，100%），差异有统计学意义（P<0.01）。治疗后2组出血并发症发生率差异无统计学意义（P=0.0976）。2组患者随访时间3～18个月，A组随访率50.0%，B组随访率58.0%，均未发生肺动脉栓塞。 结论在下腔静脉滤器保护下，CDT联合球囊扩张导管碎栓治疗急性下肢DVT较单纯CDT治疗，溶栓效果好、尿激酶用量少、不增加肺栓塞及出血发生率。
ObjectiveTo investigate the risk factors,characteristics and prognosis in Tibetan patients with venous thromboembolism. MethodsTibetan patients with VTE from plateau area,admitted in West China Hospital from January 2010 to December 2012,were recruited in the study. The VTE diagnosis was confirmed by CT pulmonary angiogram (CTPA) or vascular ultrasound examination. Risk factors,clinical symptoms,signs and laboratory tests were retrospectively investigated and follow-up by telephone interview was conducted. Results31 Tibetan VTE patients with 16 males and 15 females were included. The investigation of risk factors revealed that 15 patients suffered from obese(48.3%),10 patients suffered from highly viscous hyperlipidemia(32.3%). The most common clinical symptom was dyspnea(29%),followed by chest pain(19.4%),hemoptysis(16.1%) and cough(12.9%). The common signs were lower extremity edema(73.3%) and lung rale(36.7%). All the patients received anticoagulation therapy,and inferior vena caval filters were implanted in 2 patients. In two years' follow-up after discharge,2 patients died of tumor,2 died of pulmonary embolism,6 patients suffered from chronic embolization syndrome with lower extremity edema or pain,1 patient suffered from pulmonary hypertension after embolization,and thrombus in 20 patients disappeared or recanalized. ConclusionTibetans long-termly reside in high altitude areas with the eating habits of high-fat diet,which may increase the incidence of acquired risk factors such as viscous hyperlipidemia and obesity. There are no specific clinical symptoms and signs among Tibetan VTE patients,with dyspnea as the most common symptom and lower extremity edema as the most common sign. Patients with risk factors which can be eliminated in a short term have better prognosis.

ObjectiveTo evaluate the treatment effective of deep vein thrombosis (DVT) of low extremities. MethodsThe clinical data of 86 patients with DVT were analyzed retrospectively, which were divided into thromboectomy group (12 patients) and thrombolysis group (74 patients) according to the therapy methods. The thromboectomy group patients were treated by thromboectomy using Fogarty balloon catheter plus thrombolytie, thrombolysis group patients were treated by thrombolysis (urokinase or antithrombus enzyme of viper). ResultsThere were 8 cases healed, 4 cases relieved, 0 invalidated in the thromboectomy group and 15 cases healed, 50 cases relieved, 9 cases invalidated in the thrombolysis group at discharge. During 3-100 months of following up with an average 27 months, 10 cases and 62 cases were examined by Bultrasonic in the thromboectomy group and thrombolysis group, respectively, 6 cases were not damaged in the function of valves of the thromboectomy group, 9 cases were not damaged in the function of valves of the thrombolysis group. The rates of acute response, longtime patency, and normal valve in the thromboectomy group were higher than those in the thrombolysis group (Plt;0.05), the rate of post-thrombotic syndrome in the thromboectomy group was lower than that in the thrombolysis group (Plt;0.05). ConclusionsEarly thromboectomy is an effective way of restoring the fluency of deep vein and protecting the efficiency of the vein value organization, and reducing the sequela of DVT. Thrombolysis can only relieve the symptomation, but it can not protect the crawling and relapsing of thrombus.
ObjectiveTo explore the value of potaried technique with Trivex system in treatment for venous skin ulcer with deep venous thrombosis sequelae (DVTS) of lower limbs. MethodsTotal 166 patients with venous skin ulcer with DVTS of lower limbs were included in this study. The patients of operation group (94 patients involving 94 legs) were treated by using potaried technique with Trivex system. The patients of nonoperation group (72 patients involving 72 legs) were treated by using nonoperative method. The clinical indexes of skin infection rate, skin necrosis rate, shrinkage rate of wound area, skin depigmentation rate, ulcer healing rate and ulcer recurrence rate were used to assess the clinical curative effect between two groups on 5, 20, 120 and 360 d after operation or treatment, respectively. ResultsThere were no skin infection and skin necrosis in two groups on 5 d after operation or treatment. The rate of shrinkage of wound area and skin depigmentation of patients in operation group were significantly higher than those in nonoperation group on 20 d after operation or treatment 〔(95.8±2.138)% vs. (68.7±3.125)%，P=0.048; (87.6±1.263)% vs. (12.3±1.324)%， P=0.018〕. The rate of the ulcer healing of patients in operation group was significantly higher than that in nonoperation group on 120 d after operation or treatment (97.9%vs. 8.3%， P=0.014). The rate of the ulcer recurrence of patients in operation group was significantly lower than that in nonoperation group on 360 d after operation or treatment (5.3% vs. 97.2%， P=0.015). ConclusionThe potaried technique with Trivex system can be used as one of the surgical treatment methods for venous skin ulcer with DVTS of lower limbs.

下肢慢性静脉功能不全（chronic venous insufficiency, CVI）是国人常见的血管外科疾病。人们最早认识的是以大隐静脉曲张为代表的浅静脉功能不全。20世纪初Homans就提出治疗大隐静脉曲张的手术方式“大隐静脉高位结扎、抽剥术”，至今仍为治疗该病的经典手术方式。尽管100年来对此手术方式有所改良或改进，但手术的基本原则并未改变，即消除曲张浅静脉（不管用什么方式）以打断浅静脉返流，达到降低静脉高压的目的。......
Objective To study the significance of the levels of plasma inflammatory cytokines (IL-6，IL-8，IL-10 and TNF-α) in patients with acute deep venous thrombosis (DVT) of lower extremity. Methods Forty untreated DVT cases were selected as the subjects in the DVT group, while thirty healthy subjects, whose ages and genders showed no significant difference with the DVT patients, were collected as the control group. The plasma levels of IL-6, IL-8 and TNF-α were detected by radioimmunoassay (RIA), and the plasma level of IL-10 was measured by enzyme-linked immunosorbent assay (ELISA). Correlation analysis was used to investigate the relationships between the levels of different inflammatory cytokines within DVT group. Results The levels of plasma cytokines in the DVT group were all significantly higher than those in control group (P＜0.001). The results of the correlation analysis showed that there were positive correlations between IL-6 and TNF-α (r=0.383, P＜0.05), IL-10 and TNF-α (r=0.390, P＜0.05), respectively, within the DVT group; whereas there were no correlations between IL-6 and IL-8, IL-6 and IL-10, IL-8 and IL-10, and IL-8 and TNF-α. Conclusion The levels of plasma cytokines increased significantly in patients of DVT. Inflammatory cytokines may play an important role in acute DVT by accelerating the pace of thrombosis, intensifying the inflammatory reaction around thrombus and aggravating the injured blood vessel.
