  • Vein Disease: Your Personal Prevention Programme While Your
    Vein disease: Your personal prevention programme While your arteries transport blood containing oxygen and nutrients to the body cells, the veins are responsible for taking ‘used’ blood via the heart back to the lungs, where it can be enriched with fresh oxygen. In order for blood to be returned to the heart against the force of gravity, the vein valves must close tightly and the tissue which surrounds the veins must be strong. Otherwise the veins expand and become varicose. There’s a danger of thromboses, emboli and so-called ‘open leg’ ulcers. Self-diagnosis Spider-bursts (left) and reticular veins (right) are changes in the blood vessels which can be early signs of vein disease. Varicose veins (left and right) should be treated, if necessary surgically, as soon as possible. Deep vein thrombosis (left) is highly dangerous: You must seek treatment immediately! If you have vasculitis (inflammation of the vein wall - right) you should also visit a doctor or specialist clinic without delay. The classic symptoms of vein disease are swollen legs, pins and needles and feelings of tension in the calves, foot and calf cramps, legs which feel heavy or tired in the evening. Standing the whole day or frequent flying put a special burden on the vein system of the legs. © heigel.com www.heigel.com These things are good for your veins: Take frequent long walks as this exercises the leg and foot musculature. Sports involving sustained activity, such as hiking, swimming, jogging, skiing, dancing, cycling and gymnastics, are especially recommended. Whenever you are involved in an activity which involves sitting or standing, take every opportunity which presents itself to walk around.

  • What Is Dvt? Deep Vein Thrombosis (DVT) Occurs When an Abnormal Blood Clot Forms in a Large Vein
    What is DVt? Deep vein thrombosis (DVT) occurs when an abnormal blood clot forms in a large vein. These clots usually develop in the lower leg, thigh, or pelvis, but can also occur in other large veins in the body. If you develop DVT and it is diagnosed correctly and quickly, it can be treated. However, many people do not know if they are at risk, don’t know the symptoms, and delay seeing a healthcare professional if they do have symptoms. CAn DVt hAppen to me? Anyone may be at risk for DVT but the more risk factors you have, the greater your chances are of developing DVT. Knowing your risk factors can help you prevent DVt: n Hospitalization for a medical illness n Recent major surgery or injury n Personal history of a clotting disorder or previous DVT n Increasing age this is serious n Cancer and cancer treatments n Pregnancy and the first 6 weeks after delivery n Hormone replacement therapy or birth control products n Family history of DVT n Extended bed rest n Obesity n Smoking n Prolonged sitting when traveling (longer than 6 to 8 hours) DVt symptoms AnD signs: the following are the most common and usually occur in the affected limb: n Recent swelling of the limb n Unexplained pain or tenderness n Skin that may be warm to the touch n Redness of the skin Since the symptoms of DVT can be similar to other conditions, like a pulled muscle, this often leads to a delay in diagnosis. Some people with DVT may have no symptoms at all.

Ferhatoglu 2 1. General Surgery, Istanbul Gelişim University, Istanbul, TUR 2. General Surgery, Okan University Medical Faculty, Istanbul, TUR Corresponding author: Abdulcabbar Kartal, [email protected] Disclosures can be found in Additional Information at the end of the article Abstract Aim The aim of the present study was to evaluate the incidence of varicose veins among patients with hemorrhoidal disease and to compare its incidence reported in various community-based studies. Method The study group comprised of 100 patients who underwent surgery for symptomatic internal or external hemorrhoids; the control group consisted of 100 volunteers who received no prior therapy for hemorrhoidal disease and lacked any symptoms or findings suggestive of this condition. Subjects in both the groups were inquired with respect to their demographic data and risk factors. Both groups were asked to stand for two minutes before performing leg examinations while still in the standing position. The findings were recorded for both the groups. Varicose veins were classified according to the clinical appearance section of the Clinical, Etiologic, Anatomic, and Pathophysiologic (CEAP) classification that was developed by the 1994 American Venous Forum. Results There was no significant difference between the two groups with respect to age and body mass index (BMI). Significant relationships were identified between the groups with respect to the incidence of varicose veins and chronic constipation. The incidence of C1 and C2 varicose veins observed in the study group was higher than that observed in the control group.

  • Varicose Veins
    Varicose Veins: Diagnosis and Treatment Jaqueline Raetz, MD; Megan Wilson, MD; and Kimberly Collins, MD University of Washington Family Medicine Residency, Seattle, Washington Varicose veins are twisted, dilated veins most commonly located on the lower extremities. The exact pathophysiology is debated, but it involves a genetic predisposition, incompetent valves, weakened vascular walls, and increased intravenous pressure. Risk factors include family history of venous disease; female sex; older age; chronically increased intra-abdominal pressure due to obesity, preg- nancy, chronic constipation, or a tumor; and prolonged standing. Symptoms of varicose veins include a heavy, achy feeling and an itching or burning sensation; these symptoms worsen with prolonged standing. Potential complications include infection, leg ulcers, stasis changes, and thrombosis. Con- servative treatment options include external compression; lifestyle modifications, such as avoidance of prolonged standing and straining, exercise, wearing nonrestrictive clothing, modification of car- diovascular risk factors, and interventions to reduce peripheral edema; elevation of the affected leg; weight loss; and medical therapy. There is not enough evidence to determine if compression stock- ings are effective in the treatment of varicose veins in the absence of active or healed venous ulcers. Interventional treatments include external laser thermal ablation, endovenous thermal ablation, endo- venous sclerotherapy, and surgery. Although surgery was once the standard of care, it largely has been replaced by endovenous thermal ablation, which can be performed under local anesthesia and may have better outcomes and fewer complications than other treatments. Existing evidence and clinical guidelines suggest that a trial of compression therapy is not warranted before referral for endove- nous thermal ablation, although it may be necessary for insurance coverage.

  • Varicose Veins and Superficial Thrombophlebitis
    ENTITLEMENT ELIGIBILITY GUIDELINES VARICOSE VEINS AND SUPERFICIAL THROMBOPHLEBITIS 1. VARICOSE VEINS MPC 00727 ICD-9 454 DEFINITION Varicose Veins of the lower extremities are a dilatation, lengthening and tortuosity of a subcutaneous superficial vein or veins of the lower extremity such as the saphenous veins and perforating veins. A diagnosis of varicose veins is sometimes made in error when the veins are prominent but neither varicose or abnormal. This guideline excludes Deep Vein Thrombosis, and telangiectasis. DIAGNOSTIC STANDARD Diagnosis by a qualified medical practitioner is required. ANATOMY AND PHYSIOLOGY The venous system of the lower extremities consists of: 1. The deep system of veins. 2. The superficial veins’ system. 3. The communicating (or perforating) veins which connect the first two systems. There are primary and secondary causes of varicose veins. Primary causes are congenital and/or may develop from inherited conditions. Secondary causes generally result from factors other than congenital factors. VETERANS AFFAIRS CANADA FEBRUARY 2005 Entitlement Eligibility Guidelines - VARICOSE VEINS/SUPERFICIAL THROMBOPHLEBITIS Page 2 CLINICAL FEATURES Clinical onset usually takes place when varicosities in the affected leg or legs appear. Varicosities typically present as a bluish discolouration and may have a raised appearance. The affected limb may also demonstrate the following: • Aching • Discolouration • Inflammation • Swelling • Heaviness • Cramps Varicose Veins may be large and apparent or quite small and barely discernible. Aggravation for the purposes of Varicose Veins may be represented by the veins permanently becoming larger or more extensive, or a need for operative intervention, or the development of Superficial Thrombophlebitis.

  • A 69-Year-Old Woman with Intermittent Claudication and Elevated ESR
    756 Self-assessment corner Postgrad Med J: first published as 10.1136/pgmj.74.878.756 on 1 December 1998. Downloaded from A 69-year-old woman with intermittent claudication and elevated ESR M L Amoedo, M P Marco, M D Boquet, S Muray, J M Piulats, M J Panades, J Ramos, E Fernandez A 69-year-old woman was referred to our out-patient clinic because of long-term hypertension and stable chronic renal failure (creatinine 132 ,umol/l), which had been attributed to nephroan- giosclerosis. She presented with a one-year history of anorexia, asthenia and loss of 6 kg ofweight. In addition, she complained of intermittent claudication of the left arm and both legs lasting 2 months. This provoked important functional limitation of the three limbs, and impaired ambula- tion. She did not complain of headache or symptoms suggestive of polymyalgia rheumatica. Her blood pressure was 160/95 mmHg on the right arm and undetectable on the left arm and lower limbs. Both temporal arteries were palpable and not painful. Auscultation of both carotid arteries was normal, without murmurs. Cardiac and pulmonary auscultation were normal. Mur- murs were audible on both subclavian arteries. Neither the humeral nor the radial pulse were detectable on the left upper limb. Murmurs were also audible on both femoral arteries, and nei- ther popliteal nor distal pulses were palpable. Her feet were cold although they had no ischaemic lesions. Funduscopic examination was essentially normal. The most relevant laboratory data were: erythrocyte sedimentation rate (ESR) 120 mm/h, C-reactive protein 4.4 mg/dl (normal range <1.5); antinuclear and antineutrophil cytoplasmic antibodies were negative.
