Purpose: To investigate the prevalence and risk factors of atherosclerotic disease of the extracranial carotid artery in healthy Korean population. Methods: Eight hundred twenty-five patients without previous. history of transient ischemic attack, amaurosis fugax, and/or any neurologic deficit who underwent carotid artery ultrasonography were evaluated retrospectively. The patients were divided into five groups according to the degree of carotid artery stenosis using real-time B-mode high resolution ultrasonography; Group A-normal carotid artery, Group B-below 30% of carotid artery stenosis, Group C-from 31% to 50% of carotid artery stenosis, Group D-from 51% to 70% of carotid artery stenosis, Group E-above 71% of carotid artery stenosis. Medical Records of all patients were investigated for following factors; sex, age, family history, smoking, hypertension, diabetes mellitus, total cholesterol, HDL- cholesterol, LDL-cholesterol, TG (triglyceride), HbA-1c (hemoglobin A-lc), and folate. Results: 12.5% of asymptomatic patients have carotid stenosis due to atherosclerosis of extracranial carotid artery. The prevalence of extracranial carotid artery stenosis was as follows; Group B: 2.2%, Group C: 7.0%, Group D: 3.0%. The age, total cholesterol, LDL-cholesterol and HbA-1c were significantly higher in Group B, C, D than Group A (P 0.001, 0.016, 0.011, 0.001). The prevalence of diabetes and hypertension were significantly higher in Group B, C, D than Group A. Other factors, however, were not different among the groups. Conclusion: Asymptomatic carotid artherosclerosis is not uncommon in Korea. Carotid ultrasonography would be necessary for patients with hypertension, diabetes, and high serum cholesterol level.

원발성 하지정맥류 치료 전후의 정맥혈류역학적 변화에 관한 분석

Purpose: To evaluate the changes of venous hemodynamics after the treatment of the primary varicose vein of the lower limbs. Methods: We retrospectively analyzed 493 lower limbs (221 right and 272 left, 157 male and 336 female) who underwent surgery for the primary varicose veins from September 1994 to May 1999. All patients were evaluated using air-plethysmography (APG) pre-and post-operatively. Results: The prevalent age was 40 to 49-year-old and the male to female ratio was 1: 2. Presumed etiological factors included occupations requiring long periods of standing in 94 cases, and pregnancy in 188 female cases. The average duration of illness was 12.9±8.2 years. 232 limbs were treated with a method of the greater saphenous vein high ligation (GSV HL) and above knee (AK) stripping with varicosectomy (VS), 38 limbs with GSV HL and total stripping and VS, 101 with short saphenous vein HL and VS, 100 with external banding valvuloplasty of GSV and VS, 5 with external banding valvuloplasty of GSV only, 10 with Lintons operation, 6 with GSV branch ligation and VS, and sclerotherapy in 9. The reduction rate of venous volume (VV) were 13.9±16.6% in GSV stripping group and 20.4±18.2% in GSV valvuloplasty group. The reduction rate of venous filling index (VFI) were 53.6±31.0% in GSV stripping group and 58.9±33.7% in GSV valvuloplasty group. The increasing rate of ejection fraction (EF) were 26.9±41.1% in GSV stripping group and 21.1±32.2% in GSV valvuloplasty group. The reduction rate of ambulatory venous pressure (AVP) were 4.4±128% in GSV stripping group and 22.7±73.3% in GSV valvuloplasty group. Conclusion: In patients with primary varicose vein of the lower limbs, APG could be a useful method for the documentation of hemodynamic improvement by showing decrease in VV, VFI, AVP and increase in EF.
