Background: Conventional stripping is considered to be the standard procedure for great saphenous vein (GSV) varicosities, but many other alternative treatments such as cryostripping, endovenous laser therapy (EVLT), radiofrequency ablation, and ultrasound-guided foam sclerotherapy have been developed. Among them, both cryostripping and laser therapy have been reported to be less traumatic, with lower rates of complications and recurrences when compared to conventional stripping. To compare the efficacy of these treatments, we have analyzed and compared the mid-term clinical outcomes of cryostripping and EVLT. Methods: Patients diagnosed with varicose veins of the GSV and treated with cryostripping or laser therapy between September 2008 and April 2013 were enrolled in this study. Duplex ultrasonography was used for the diagnosis and evaluation of varicosity and reflux, and the clinical-etiology-anatomy-pathophysiology classification was used to measure the clinical severity. The symptoms, Venous Clinical Severity Score (VCSS), recurrence rates, and complication rates of the cryostripping and laser therapy groups were analyzed and compared. Results: A total of 68 patients were enrolled in this study. 32 patients were treated with cryostripping, and 36 patients were treated with laser therapy. The median follow-up period was 29.6 months. Recurrence was noted in three patients from the cryostripping group and in two patients from the EVLT group. There was no difference in the VCSS score, operative time, duration of hospital stay, and complication rate between the cryostripping group and the EVLT group. Conclusion: The mid-term clinical outcomes of cryostripping were not inferior to those of EVLT. Further, considering its cost-effectiveness, cryostripping seems to be a safe and feasible method for the treatment of varicose veins.

A 36-year-old man presented to the hospital with protruding blood vessels in his left lower leg accompanied by cramping. An ultrasonographic examination of the leg revealed focal reflux without truncal vein reflux. During phlebectomy, the varix was found to be connected to the intraosseous vein through a tibial opening. Postoperative computed tomography and magnetic resonance imaging showed an osteolytic lesion in the tibial shaft and an intraosseous vascular anomaly. The patient was discharged without complications and scheduled for periodic follow-ups. This young man's varicose vein seemed to be from a tibial intraosseous vascular anomaly, which is extremely rare.

A 27-year-old female patient was referred due to an edematous left lower extremity. Both saphenous veins had been ablated with an endovenous laser procedure used to treat varicose veins. Venography revealed that the left common femoral vein had been divided and that thrombosis was present at the site of division. No veins were available around the thighs. The patient was treated using a staged procedure. During the first stage, a ringed polytetrafluoroethylene graft was used to repair the common femoral vein, and an arteriovenous fistula was constructed from the femoral artery to the graft using a short segment of cephalic vein to increase graft patency. The edema was relieved postoperatively and the graft was patent. During the second stage, which was performed 6 months later, the fistula was occluded by coil embolization. The staged procedure described herein provides an alternative for venous reconstruction when autologous vein is unavailable.

Background: Lower-limb varicose veins (VVs) are common and known to have a higher prevalence among people who work in occupations requiring prolonged standing. In the Republic of Korea, however, VV-related occupational factors have seldom been examined. This study was conducted to assess the prevalence of VVs among nurses, an occupational group considered to be at high risk of VVs, and determine the occupational risk factors of prolonged standing. Methods: Between March and August 2014, a questionnaire survey coupled with Doppler ultrasonography was conducted on the nurses working at a university hospital. Results: A total of 414 nurses participated in the survey and diagnostic testing. From the survey analysis and test results, the prevalence of VVs in nurses was estimated to be 16.18%. Significant factors for venous reflux were age [odds ratio (OR) = 1.06, 95% confidence interval (CI) = 1.03-1.10], pregnancy (OR = 2.15, 95% CI = 1.17-3.94), and delivery (OR = 2.02, 95% CI = 1.08-3.78). The statistical significance of these factors was verified after risk adjustment for sociodemographic factors (OR = 3.40, 95% CI = 1.27-9.09). Conclusion: Factors significantly associated with venous reflux were increasing age and prolonged working hours (${\geq}4hours$) in a standing position (OR = 2.80, 95% CI = 1.08-7.25), even after risk adjustment for sociodemographic factors. This study is significant in that an objective diagnosis of VVs preceded the analysis of the risk factors for VV incidence, thus verifying objectively that VVs are associated with occupations requiring prolonged hours of working in a standing position.

복재-대퇴 접합부 박리 시 외음부동맥과 대복재정맥 분지의 해부학적인 변이는 자주 발견되나 대퇴동맥과 대퇴정맥의 위치 전이는 매우 드문 것으로 알려져 있다. 하지정맥류 수술 시 이러한 해부학적 변이를 염두에 둔다면 수술 시 발생되는 문제점들을 최소화할 수 있을 것으로 생각한다.

One hundred and seventy-four patients were treated in this Department since 1956. One hundred and fifteen patients of them were surgically treated. They were classified on the basis of the disease entity as follows; 48 case of thrombo-angiitis obliterance, 8 cases of Leriche syndrome, 12 cases of arterial embolism, 36 arterial aneurysm, 5 arterio-venous fistula, 15 arterial and venous injuries, 8 pulseless diseases, 2 coarctation of aortas, 15 varicose veins, 12 thrombophlebitis, 9 superior venacaval syndromes, 2 inferior vena caval obstructions and Raynaud's diseases. All the cases of the Burger's diseases were males, and half of them were in the fourth decades, 39 cases underwent undergone unilateral or bilateral sympathectomies. All the Leriche syndromes were males aged over fifty. Three cases out of six were suffering from diabetes mellitus. 2 cases underwent aorto-femoral bypass graft with Y-shaped dacrons. And two embolectomies were performed in 2 cases. Eight cases of arterial embolisms among 12 had mitral valvular diseases with auricular fibrillation The most common site of lodgement of emboli was femoral artery. Nine out of 14 underwent embolectomies with Fogarty catheters. There were 14 peripheral arterial aneurysms, 16 thoracic and/or abdominal aortic aneurysms, and 4 dissecting aneurysms. Most frequent cause of peripheral arterial aneurysms were external trauma. Thoracic and abdominal aortic aneurysms were non-traumatic. And four cases of the dissecting aneurysms had significant hypertension and aged over fifty. Among 5 cases of arteriovenous fistulas, 2 cases hand typical Branham's sign, and they were normalized after operation. Eight cases of pulseless disease were females and aged from three to twenty-five. Three out of them were treated surgically using dacron prosthetic grafts, but the results of the surgery were variable and not satisfactory. A case of coarctation of aorta was treated surgically with an excellent result. Fourteen out of 15 varicose veins underwent ligation of the saphenous vein system, exstirpation of the varicose veins, stripping or some combination of these methods. Two cases of superior vena caval syndromes were operated by bypass graft between the left innominate vein and the right auricle. Two cases of inferior vena caval obstructions were operated upon through right atrial route using extracorporial circulation. All the four cases of vena caval obstructions showed excellent results postoperatively. Two cases out of 12 thrombophlebitis underwent thrombectomies. One of two Raynaud's diseases was surgically treated with an excellent result.
