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 evaluate improved effect for deep venous valve function after superficial vein surgery of lower extremity in the intermediate stage. Methods Totally 43 patients (55 limbs) with varicose veins of lower extremity were enrolled to accept surgical management of vein systems in our department from March 2006 to October 2006. All patients were respectively followed up after 6 months and 4 years about the changes of deep venous valve function with color Doppler ultrasonography. Results Thirty-nine patients’ deep venous valve function kept well up to now, and there was no significant difference between the two results. Four patients without proximal saphenous vein ligation recurred, and there was reflux in deep venous. Conclusion Endovenous laser treatment and ablation of varicose veins of lower extremity with deep venous insufficiency could improve deep venous valve function effectively. Proximal great saphenous vein ligation is important for successful operation.
ObjectiveTo analyze the causes of lower extremity varicose veins and assess the value of deep vein imaging in diagnosing and treating venous diseases, according to deep vein angiography examination results under digital subtraction angiography. MethodsDuring January 2012 to January 2013, 689 cases of lower limb varicose veins in 394 patients underwent lower extremity deep venous anterograde contrast examination, among which 87 patients also underwent left femoral venous trocar puncture angiography examination and 46 patients underwent femoral vein puncture inferior vena cava angiography examination at the same time. Then the results of imaging data were analyzed. ResultsThe causes of lower limb varicosity, according to its incidence, were as follows:primary deep venous valve incompetence (349 limbs of 184 patients) accounting for 50.7%, simple varicose veins of lower limbs (148 limbs of 95 patients) accounting for 21.5%, left iliac vein compression syndrome (121 limbs of 69 patients) accounting for 17.6%, cloth plus syndrome (54 limbs of 34 patients) accounting for 7.8%, post-thrombotic syndrome (16 limbs of 11 patients) accounting for 2.3%, and Klipple-Trenaunay syndrome (1 patient) accounting for 0.1%. ConclusionVaricose vein of lower limb is a common clinical manifestation of a variety of diseases, and the primary deep venous valve incompetence is the leading cause. Varicose veins of lower limb deep vein angiography is a reliable method for examination of lower extremity venous disease, and a basis for the choice of other treatments as well.
ObjectiveTo evaluate feasibility and clinical effect of individual therapy for venous ulceration of lower extremity. MethodsFrom February 2012 to February 2014, 360 cases (totally 421 lower limbs) treated by the individual therapy were analyzed retrospectively. There were 126 male and 234 female patients, with a mean age of 53 years (ranging from 45 to 78 years). The venous ulceration occurred in left limb for 176 cases, right limb for 123 cases, and both limbs for 61 cases. The individualized treatment plans were performed for all the patients according to the color Doppler before the operation. The perforating vein was ligated during the operation, and elastic stockings were wore after operation. The operation time, postoperative VAS pain score, perioperative complications, ulcer healing and recurrence were recorded. ResultsThe operations were completed in all the patients, the average operation time was 35 min. The average VAS pain score was 2.6 at 8 h after operation, the pain was disappeared nearly at 24 h after operation. The time of returning to normal activity was 3 d. The incision bleeding occurred in 5 cases, the ulcer infection occurred in 32 lower limbs. The patients were followed-up for 12 months to 24 months, all the ulcers were healed, there were 9 cases of recurrence. ConclusionIndividual therapy for venous ulceration of lower extremity is safe, effective, fewer complications, fast ulcer healing, and less postoperative pain.
Foam stability affects the efficacy and incidence of side effects of foam sclerotherapy. Exploring the relationship between foam pressure difference and foam stability can provide ideas and basis for obtaining more stable foam. In the experiment, sodium cod liver oleate foam was selected, and poloxamer 188 (concentration of 0%, 4%, 8%, 12%) was added to realize the change of foam pressure. By using the self-written program to process the foam pictures, the foam pressure difference and the relationship between the foam stability indicators (water separation rate curve, half-life) and the foam pressure difference were obtained. The results showed that at first the foam pressure increased with the increase of the concentration, and then it decreased with the increase of the concentration and reached a peak at the concentration of 4%. The foam pressure difference decreases continuously with the increase of decay time. When the additive concentration is low, the foam average pressure difference increases. And if the additive concentration is too high, the foam average pressure difference decreases. The smaller the foam pressure difference is, the better the foam stability is. This paper lays a foundation for the research on the stability of foam hardener.
