PVD Vs CVI Flashcards
PVD pathology
Arteriosclerotic narrowing of the lumen of arteries resulting in decreased blood supply to the extremities
PVD Causes/Incidence
Usually caused by arthrosclerosis Similar risk factors for coronary artery disease Peak incidence 40 to 70 years of age Hyperlipidemia Smoking Diabetes
PVD Signs/Symptoms
Usually first symptom: complaint of calf pain (claudication)
Cold/numbness of two extremities
Progresses to pain at rest
PVD Physical Findings
Shiny/hairless skin Dependent Rubor Pallor Cyanosis Ulcerations Reduced pulses
PVD Lab/Diagnostics
Doppler ultrasound to evaluate flow
**ankle brachial index (ABI)
Arteriography: most definitive test
PVD Management
Stop smoking and all tobacco use Exercise: walk one hour per day; stopping during pain and resuming with pain subsides to develop collateral circulation Cilostazol (pletal) Weight reduction as needed Nanas diabetes and hyperlipidemia Angioplasty Bypass surgery Amputation
CVI Pathology
Impaired venous return due to the either destruction of valves, changes to the deep thrombophlebitis, leg trauma, or sustained elevation of venous pressure
CVI Causes/Incidence
More common in women than men
Maybe genetic predisposition
History of leg trauma; may be associated with varicose veins
CVI Signs/Symptoms
Aching of the lower extremities relieved by elevation
Edema after prolong standing
Night cramps of the lower extremities
CVI Physical Findings
Trophic changes with brownish discoloration Stasis legal service Edema of lower extremities Dermatitis maybe, Cool to touch
CVI Lab/Diagnostics
Nonspecifically diagnostic of chronic venous insufficiency
Rule out edema due to heart failure and other causes (may Thurner syndrome: compression of left common iliac by overlying right common iliac pain equals LLE DVT)
CVI Management
Bedrest with leg elevated to diminish chronic edema
Use of heavy duty elastic support stockings
Weight reduction in the obese
Treat derma Titus or ulcers as indicated
Acute weeping dermatitis
– tap water compresses
– Hydrocolloid dressing
– for less acute dermatitis, hydrocortisone cream
