VARICOSE VEINS

ICD-9: 454.x

Description

Varicose veins are enlarged, twisted, superficial veins. They may occur in almost any part of the body, but most frequently they occur in the lower legs, involving the greater and lesser saphenous veins. The condition is most common after age 50 and in obese persons, affecting more women than men. Varicose veins tend to be inherited.

Etiology

Defective or damaged valves in the veins prevent the blood from flowing freely toward the heart. This buildup of pressure in the superficial veins causes varicosities. Varicose veins may be due to an inherited defect or to venous diseases. They also may be produced by conditions such as pregnancy or jobs requiring prolonged standing or heavy lifting. Many factors can aggravate the situation.

Signs and Symptoms

Clients may be asymptomatic even though the varicose vein condition is severe. Quite frequently, however, the affected veins are visually evident. Characteristic symptoms with varicose veins of the legs include dull, aching heaviness or a feeling of fatigue after standing. Cramping may occur, followed by edema and stasis pigmentation, a tan discoloration of the skin.

Diagnostic Procedures

In most cases, visual observation may be all that is necessary. Phlebography may be performed for diagnosis. Doppler ultrasonography detects possible backflow in deep or superficial veins.

Treatment

The use of elastic stockings, a moderate exercise program, and avoidance of prolonged periods of standing or lifting are recommended initially. Injection of a sclerosing agent into small vein segments is useful for destroying small spider veins but will not work on varicose veins. Severe varicose veins may require stripping and ligation, but clients must have patent deep venous channels. A procedure known as endovenous laser therapy destroys the vein with a laser. The procedure is usually performed in an outpatient setting under local anesthesia, taking about 40 minutes. The small laser, guided by ultrasound, is passed into the vein. When it is fired at multiple locations, the vein is destroyed. Radiofrequency ablation is a similar technique with an endovascular laser, but it uses heat to destroy the vein.

Complementary Therapy

It is recommended that clients elevate the legs as much as possible, wear support stockings, lose weight, and avoid alcohol. They should not massage directly over the varicose veins.

CLIENT COMMUNICATION

Tell clients not to cross their legs when sitting; rather, they should cross their ankles. Wearing support hose and getting up frequently to walk is helpful. Remind clients to sit with their legs elevated if possible.

Prognosis

The prognosis is good; however, further varicose veins may develop, requiring additional treatment.

Prevention

Prevention of varicose veins includes avoiding prolonged standing or lifting, avoiding constrictive clothing, and elevating the legs when possible. If obesity is a problem, have the client begin a plan to lose weight.

ANEURYSMS: ABDOMINAL, THORACIC, AND PERIPHERAL ARTERIES ICD-9: 441.4 ABDOMINAL ICD-9: 441.2 THORACIC ICD-9: 442.89 PERIPHERAL ARTERIES Description FIGURE. Aortic aneurysms. (From Thomas, CL : Taber’s Cyclopedic Medical Dictionary, ed 21. FA Davis, Philadelphia, 2009, p 126, with permission.) An aneurysm is a local dilation of a blood vessel due to weakening of its walls. Aneurysms may be sacculated (shaped like a sac), fusiform (a spindle-shaped enlargement), or dissecting (the layers of the vessel wall are separated). Aneurysms may cause a blood clot or thrombus to form along the wall of a blood vessel, hemorrhage from rupture, or ischemia. Three additional common types of aneurysms discussed here are abdominal aortic aneurysms (AAA), thoracic aortic aneurysms (TAA), and peripheral artery aneurysms (PAA). All three are more common in men older than age 60. AAAs are a leading cause of death in the United States. Both AAAs and TAAs are life-threatening and constitute a medical emergency when the aneurysms are expanding or rupture. P...
COMMON SYMPTOMS OF CARDIOVASCULAR AND LYMPHATIC SYSTEMS DISEASES AND DISORDERS Individuals with cardiovascular diseases may present with the following common complaints, which deserve attention from health-care professionals: Fatigue Dyspnea, orthopnea Fever Weakness Tachycardia and palpitations Pallor Hypertension Chest pain Night sweats Edema Nausea, vomiting, or anorexia Anxiety Headache Claudication
MITRAL INSUFFICIENCY/STENOSIS ICD-9: 424.0 Description In mitral insufficiency, blood from the left ventricle flows back into the left atrium. In mitral stenosis, blood flow is obstructed from the left atrium to the left ventricle. In both cases, the result is an enlarged left atrium. Etiology Mitral insufficiency, or stenosis, most often is secondary to childhood rheumatic fever, MI, or infective endocarditis in which vegetations on the heart valves cause stenosis. Severe left-sided heart failure, or mitral valve prolapse, a falling or dropping down of the valve tissue, may occur. FIGURE. Gross pathology showing mitral stenosis. The left atrium has been opened to show thickened mitral valve leaflets from above. (Centers for Disease Control and Prevention. Dr. Edwin P. Ewing, Jr. Creation date 1973.) Signs and Symptoms In both conditions, there may be orthopnea, dyspnea, fatigue, palpitations, peripheral edema, atrial fibrillation, pulmonary hypertension, and distention of the jugular veins. Abno...
VALVULAR HEART DISEASES AND DISORDERS Diseased heart valves may malfunction in two ways. The opening formed by a valve may be too large to close completely, so blood leaks back past the valve into the heart chamber from which it was pumped. Or the valve opening may be too narrow, a condition called valvular stenosis, so it impedes the flow of blood through the valve when it should be open and allows blood to leak back when it should be closed (regurgitation). Either condition can cause heart failure. The two most commonly affected valves are the mitral and the aortic valves, whereas the pulmonary and tricuspid valves rarely are affected. Diseased valves, the result of rheumatic heart disease, are less common because the incidence of rheumatic heart disease has declined in the United States. Heart murmurs, periodic sounds heard during auscultation with a stethoscope, are generated by blood flow through the heart when there is an anomaly. Murmurs can be caused by blood leaking back through an incompetent or deformed valve...
ATRIAL FIBRILLATION ICD-9: 427.31 Description In atrial fibrillation, the two atria in the heart beat irregularly, often quite rapidly, and out of rhythm with the lower ventricles. The heart rate can be as high as 175 beats per minute. Because of the complications of atrial fibrillation, it is considered a medical emergency. During fibrillation, blood can stagnate in the atria and clot. If a clot travels to the brain, a CVA may occur. Etiology Injury to the heart or abnormalities of the heart are likely the cause. These include hypertension, congenital birth defects, hyperthyroidism, previous episodes of heart problems, MI, abnormal or diseased heart valves, some viral infections, and sleep apnea. The incidence is greater when there is a family history of atrial fibrillation, when there has been binge drinking, and when a person ages. Signs and Symptoms Signs and symptoms can be sporadic or chronic. Because the heart is not beating efficiently, clients often feel a “racing” of the heart an...
