  • Insertion of Inferior Vena Cave Filter in Treating Lower Extremity Deep Venous Thrombosis

    Objective To discuss and evaluate the value of insertion of inferior vena cava filter in treating lower extremity deep venous thrombosis (DVT). Methods Inferior vena cava filters were placed in 46 patients with lower extremity DVT prior treatment, 20 in which were treated by therapy with anticoagulation and thrombolysis, and therapy with pressure gradient, and the other 26 patients by operation and thrombolysis therapy, and therapy with pressure gradient. Whether patients occurred pulmonary embolism was observed and the form and site of filters were monitored by periodic fluoroscopy. Results Inferior vena cava filters were placed successfully in all patients, 38 cases were implanted permanence inferior vena cava filter, 8 cases were implanted temporary inferior vena cava filter. Symptoms and signs of DVT disappeared or remitted in 44/46 patients after treatment. None of pulmonary embolism was occurred. Follow up 2-24 months (average 13 months) for 36 cases with permanence inferior vena cava filter, there was no complication of the filter and pulmonary embolism occurred. Conclusions The method of inserting inferior vena cava filter is simple and safe, which can prevent pulmonary embolism effectually to offer sufficient safeguard for the treatment of DVT.

  • Application of Potaried Technique with Trivex System in Treatment for Venous Skin Ulcer with Deep Venous Thrombosis Sequelae of Lower Limbs

    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.

  • Clinical Application of Autologous Peripheral Blood Stem Cells Transplantation in Treatment for Thromboangiitis Obliterans

    Objective To investigate the efficiency and safety of autologous peripheral blood stem cell transplantation (ABSCT) in treatment for thromboangiitis obliterans. Methods Fifty patients (62 affected limbs) with thromboangiitis obliterans were treated by ABSCT. A series of subjective indexes including improvement of pain and cold sensation and objective indexes including intermittent claudication distance, ankle brachial index (ABI), skin temperature, and improvement of foot skin ulcer were evaluated. Results Due to necrosis in middle and lower part of leg, 4 of 50 patients (4 lower limbs) were taken extremity amputation on 3 weeks after ABSCT, 46 patients kept their legs successfully. On 1 month after ABSCT, the legs pain and cold sensation of 46 patients (58 affected limbs) vanished, and the score of feet pain and cold sensation after ABSCT were better than those before ABSCT (P<0.05). The intermittent claudication distance, skin temperature, and ABI of 46 patients with kepting their legs on 3 months after ABSCT significantly increased as compared with before ABSCT 〔intermittent claudication distance:(80.38±45.53) m versus (330.56±142.31) m;skin temperature:(26.50±0.46) ℃ versus (31.49±0.45) ℃;ABI:0.41±0.02 versus 0.71±0.05〕, the differences were statistically significant(P<0.05). Six months after ABSCT, different degree neonatal lateral vessels were found in 58 affected limbs of 46 patients by lower extremity arteriography. The complications were not found in all the patients by laboratory or CT detection, such as malignant tumors, retinal hyperplasia, aneurysm and so on. After ABSCT, 40 patients were followed up for 9 to 36 months (mean 22.5months), the symptom had improved. Due to leg pain aggravated after 6 months, score of pain feelings was 4 in 6 patients and with toe ulcers, who had ABSCT again. Eighteen months after transplantation, the patients had only debilitation of lower extremity. The pain feeling was improved (score of pain feeling was 1). The toe ulcer was healed and no angiosclerotic myasthenia happened. Conclusions ABSCT is a simple, safe, and effective method, especially in treatment for patients with severe lower limb ischemia who is no arterial reconstruction is feasible. It could improve the quality of life of patients and might be avoided amputation of lower extremity or foot.

  • Combinative Use of Radiofrequency and Transilluminated Powered Phlebectomy in Treatment of Varicose Veins of Lower Extremity

    Objective To evaluate the efficiency and safety of combinative use of radiofrequency and transilluminated powered phlebectomy for treatment of varicose veins of lower extremity. Methods Three hundred and twenty-one cases of varicose veins of lower extremity were randomly divided into three groups: group A (102 cases): endovenouser whole range closure in situ for great saphenous vein by radiofrequency and transilluminated powered phlebectomy for varicose veins of leg; group B (97 cases): endovenouser whole range closure in situ for upper leg part of great saphenous vein by radiofrequency and transilluminated powered phlebectomy for varicose veins of leg; 122 conventional treatment cases, which high ligation and stripping of great saphenous vein, blood vessel branches and communicating branches resection and ligation were used, were selected as controlled group (group C). Consequences and complications of operation were checked. Results In all cases, the symptoms of swelling in lower extremity, soreness and infirmity disappeared within one month after operation, skin pigmentation was alleviated within one month after operation, and disappeared gradually within three months. Contrasting three groups in complications of skin numbness of legs, ecchymosis of upper leg, wound hematoma, and swelling below ankle, there was no statistical difference between group A and B, and there was statistical difference between group A and C, and B and C. There were more complications in conventional group than those in mini-invasive groups. There was no statistical difference in leg ecchymosisa between group B and C. No deep vein thrombosis of lower extremity and incision infection was detected in all cases. Conclusion It is simple and definitely efficient to combine radiofrequency with transilluminated powered phlebectomy for treatment of varicose veins of lower extremity. Powered phlebectomy is efficient in removal of varicose vein, but not suitable for phlebectomy for trunk of great saphenous vein.

    Objective To assess the curative effect of percutem transilluminated with negative pressured on the potaried technique on the treatment of venous ulcer in lower extremity. Methods The clinical date of 300 cases involving 300 legs with venous ulcer in lower extremity, who underwent the percutum transilluminated negative pressured potaried technique using TRIVEXTM Ⅱ potaried system or the percutum transfixion surgical treatment from October 2005 to June 2009, were analyzed. Three hundred cases were randomly divided into potaried group and transfixion group. In potaried group, there were 190 cases involving 190 legs treated with TRIVEXTM Ⅱ potaried system. In transfixion group, 110 cases involving 110 legs treated with percutum transfixion. The clinical indexes of skin infection rate and skin necrosis rate, shrinkage rate of wound area and skin depigmentation rate, ulcer healing rate and ulcer recurrence rate were calculated to assess the clinical curative effect on day 5, day 20, day 120 and day 360 after operation respectively. Results The rates of skin infection and skin necrosis were significantly decreased in potaried group compared with transfixion group on day 5 after operation (P<0.05), the rates of shrinkage of wound area and skin depigmentation were significantly increased in potaried group compared with transfixion group on day 20 (P<0.05). The ulcer healing rate was not significantly different between the two groups on day 120 (Pgt;0.05). Ulcer recurrence rate was remarkably lower in potaried group than that in transfixion group on day 360 (P<0.05). Conclusion It can be concluded that percutem transilluminated with negatived pressured on the potaried technique with TRIVEXTM Ⅱ potaried system can efficiently promote the healing of venous ulcer in the lower extremity, and at the same time it has an ascendancy in lessening skin infection and skin reinjury.
