Background: Endovenous laser treatment has recently been introduced as a less invasive technique, with many good results reported, A 980-nm diode laser was used on the great saphenous vein (GSV) occlusions in patients with varicose veins, due to GSV reflux, and the therapeutic effects analyzed. Material and Method: Between September 2003 and February 2006, 238 patients (332 cases) with GSV reflux underwent endovenous laser treatment with a 980-nm diode laser. Operative procedures were simultaneous endovenous laser treatment and ambulatory phlebectomy. The preoperative clinical findings, postoperative complications and postoperative duplex US follow up results at 1 and 3 months were reviewed. Result: Postoperative complications were ecchymosis in almost cases, paresthesia 68 cases (20.5%) and skin burn in 3 cases (0.9%). Follow up duplex US revealed 26 and 10 cases at 1 and 3 months of GSV reflux or partial recanalization, with therapeutic success rates of 91.3 and 87.9%, respectively. Conclusion: The treatment of GSV occlusion with an endovenous laser is less invasive than traditional GSV stripping, but relatively high recanalization was experienced, possibly due to inadequate laser power, laser fiber pullback speed or an extremely dilated GSV. However, continuous attempts will be required to reduce the recanalization after the procedure, with accurate follow up using duplex US.

Objectives : The Levator Ani Muscles Training(LAMT) is one of the well known very effective prevention and treatment method of some specific diseases in the anal organs, digestion system, urinary organs and genital organs, which means LAMT could be considered as an independent exercise. Methods : Chinese databases were searched and found one good source named CNKI(China National Knowledge Infrastructure) where there were downloaded 154 articles, out of which were finally selected 82 used for the introduction of the historical background, health-effectiveness, working mechanism, training methods, etc. Results : LAMT as an independent exercise, is considered very effective for the prevention of diseases in the anal organs, e.g. hemorrhoids, anal fissure, rectal prolapse; urinary organs, e.g. urinary incontinence, frequent micturition; digestion system, e.g. visceroptosis, diarrhea, chronic enteritis; genital organs, e.g. prostatitis, impotence, premature ejaculation, feminine vaginal relaxation, sexual indifference, etc. It is also told LAMT is effective for coronary heart disease, hyperyension and varicose veins of lower extremity to a certain degree. LAMT is also very similar to the Kegel exercise in couple of aspects. They are equally effective for the urinary incontinence and impotence. Conclusions : LAMT as an independent exercise has developed and become more and more health-effective, especially through the combination with the Qigong exercise, and thus many training methods have been introduced. There are not many scientific research and development with very limited accomplishments even in China. It is strongly required to strengthen the research and development activities so that LAMT will become one of the very effective natural healing soonest possible.

While working in an industrial environment which requires extended periods of upright posture; workers tend to develop muscle fatigue due to the constant load on lower-limb muscles. In addition, when working while bending knees; muscle fatigue of lower back and hamstrings is increased due to the abnormal posture. This can lead to damage of muscles, induce musculoskeletal disorders, and reduce long-term working efficiency. Recent medical studies have shown that long-term working in an upright posture can induce musculoskeletal disorders such as foot fatigue, edema, pain and varicose veins. Likewise, medical and rehabilitation expenses have grown due to the increase in musculoskeletal conditions suffered by workers. For this problem, we aim to develop a device that can reduce the physical fatigue on the lower limbs by supporting the weight of workers during the extended periods of upright and bending postures in the industrial environments. In this paper, we have designed and manufactured a wearable weight support system; with a user intention algorithm that the users can maintain various postures. For validation of the developed system, we measured the muscle activity of the users wearing the system with EMG sensors.

Background : Klippel-Trenaunay-Weber syndrome (KTS) is a rare congenital medical condition characterized by complex vascular malformation. KTS consists of a classic triad of capillary malformation (hemangioma), venous malformations and bone or soft tissue hypertrophy causing limb asymmetry. The aim of this report is to describe management for gait disturbance and foot pain in a Patient with KTS using custom-made total contact insole. Case presentation : A 32-year-old man with KTS presented with a 3-year history of gait disturbance on hard surface due to right first toe pain and Achilles tendon tightness. The patient had soft tissue hypertrophy, varicose veins and port-wine stains over the right lower limb associated with KTS. True leg length discrepancy was 2 cm. We prescribed custom-made total contact insole to protect his deformed foot and correct leg length discrepancy. The insole of right side included wedge shaped heel lift and the insole of left side included full length lift to add extra support on unaffected side. Also, we provided compression stocking and physiotherapy including manual lymphatic drainage for lymphedema and stretching exercise for tightness in right lower extremity. At 3 years follow-up, postural alignment including pelvic obliquity was improved using a custom-made total contact insole. The degree of scoliosis and foot pain were also reduced. Conclusion : An individualized and multidisciplinary approach is essential regarding the complexity of comorbidities in patients with KTS. For patients with KTS, orthotic management should be considered to prevent and correct deformities related to KTS. Active orthotic management, compression stocking and physiotherapy can enhance the quality of life and function in patients.

Background: The aims of the present study were to assess and compare mid-term clinical outcomes including recurrences between endovenous laser therapy (EVLT) and stripping. Material and Method: Between January 2007 and February 2010, 318 limbs in 237 patients with saphenous truncal varicosities were treated by laser energy using a 980 nm diode or were treated with conventional stripping. At the initial visit and at 1, 2, 6, 12, 18, 24, and 36 months postoperatively, clinical examination and questioning for Venous Clinical Severity Score (VCSS) as well as duplex ultrasonography were done. In order to compare clinical outcomes between the two treatment groups, EVLT versus stripping, all data were processed and analyzed. Result: There were no significant differences between the two treatment groups in the extent of the reflux and the number of insufficient perforating veins. The in EVLT and the stripping group at 12 months were $90.3{\pm}4.5%$ and $93.9{\pm}4.2%$, respectively (p>0.05). Total recurrence rates were 4.4% in the EVLT group and 1.5% in the stripping group (p>0.05). In both groups, the VCSS scores were significantly reduced at week 1, 1 month, and 2 months after EVLT or stripping (p<0.001). Conclusion: Efficiency in eliminating truncal saphenous vein incompetence and reducing venous clinical severity were equal in the two treatment groups.

Background: There are limited number of reports on May-Thurner syndrome (Iliac vein compression syndrome) in Korea, We analysed the clinical features, diagnostic modalities and endovascular treatment of May-Thurner syndrome. Material and Method: We reviewed 12 cases of May-Thurner syndrome between March 2001 and June 2003. Mean age was $57.6\pm2$ years. We were used in venography, color doppler and computed tomographic angiography as diagnostic modalities and in thrombolysis, thrombectomy, angioplasty and stent insertion as endovascular treatment. Result: Clinical features showed edema of lower extremities in 4 patients, pain of lower extremities in 1 patient, edema with pain in 5 patients, and all in 1 patient. In one patient, he did not have any pain and any edema of lower extremities but was diagnosed as May-Thurner syndrome using venography due to varicose veins on lower extremities. Diagnostic modalities included venography, computed tomographic angiography in all patients with clinical presentation except in one patient and color doppler was only performed only in 4 patients. Four kinds of endovascular treatment were performed for May-Thurner syndrome, angioplasty in 11 patients, stent insertion in 10 patients, thrombectomy in 9 patients and thrombolysis for 7 patients. Nine patients were followed up and we can show good blood flow in Left iliac vein for 7 of 9 patients. Conclusion: it is necessary to recognize the possibility of May-Thurner syndrome in Deep vein thrombosis patients and we should use a variety of modalities to diagnose May-Thurner syndrome. Finally, endovascular treatment is a safe and effective therapy for May-Thurner syndrome.

Background: Endovenous laser treatment (EVLT) has recently been introduced as a less invasive technique for treating an incompetent small saphenous vein and many good results have been reported. The purpose of this study is to assess the efficacy and safety of EVLT combined with high ligation in patients with an incompetent small saphenous vein. Material and Method: The study included 60 patients (66 limbs) who were treated with EVLT combined with high ligation of an incompetent small saphenous vein between January 2006 and May 2009. The preoperative clinical findings, the postoperative results and the postoperative ultrasonography follow up results at 1 and 3 months were reviewed. Result: Postoperative complications were observed in 17 patients (15 limbs, 28.3%) and postoperative paresthesia occurred in 5 limbs (7.6%), but there was no deep vein thrombosis. Ultrasonography follow up at 3 month was performed in 93.9% of the limbs (62/66). The vein occlusion rate at 1 and 3 months were found to be 91.9% (57/62) and 90.3% (56/62), respectively. Conclusion: We performed EVLT combined with high ligation and ambulatory phlebectomy in patients with an incompetent small saphenous vein, and this all revealed relatively satisfactory results with a low complication rate, but it showed a relatively low cure rate even though we also performed EVLT combined with high ligation altogether. We need to determine whether EVLT combined with a high ligation procedure will improve the venous occlusion rate. We also need to investigate how we can minimize the occurrence of nerve injury.
