Venous Insufficiency
Aka: Venous Insufficiency, Venous Stasis, Chronic Venous Insufficiency, Lipodermatosclerosis
See AlsoVaricose Vein
Risk FactorsObesity Congestive Heart Failure Diabetes Mellitus
PathophysiologyNormal Venous valves prevent backflowDistal to Proximal vein backflow Superficial to Deep vein backflow Incompetent valves allow backflow when legs relaxResults in distal venous Hypertension Primary etiology for Chronic Venous Insufficiency
Symptoms and SignsInitial ChangesVaricose Vein sTan or reddish brown skin color changes Weeping and excoriated skin Pedal edema Later ChangesLipodermatosclerosisInduration at medial ankle to mid-leg Advanced ChangesBrawny edema above and below fibrotic areaUlceration s
ComplicationsVenous Stasis Ulcer sMore common in older women Chronic and often recurrent Postphlebitic SyndromeChronic Leg Edema Lipodermatosclerosis (see signs above) Deep Venous Thrombosis Superficial Thrombophlebitis Pigmentation Ulceration Overlying Skin ChangesEczema Cellulitis and other secondary infection
DiagnosisDuplex Ultrasonound (B-Mode and Directional Pulse )Can accurately assess venous reflux Can also be used to assess Arterial Insufficiency With Ultrasound ankle/brachial index (See below) Descending VenographyNot as accurate as Duplex scanning
ManagementConfirm No Arterial Insufficiency Assess before managing Venous Insufficiency Ankle-Brachial Index Blood Pressure measurementDoppler ultraound measurement Elevate Legs above Heart 30 minutes each tid-qid Compression stockings (Jobst Stockings )Intermittent Pneumatic Compression PumpsIndicationsObesity Moderate to Severe edema ContraindicationsUncompensated Congestive Heart Failure Diuretic sShort term use Indications: Severe edema See Venous Stasis Ulcer Management
