Peripheral Vascular Disease

Arterial versus Venous Insufficiency

Arterial Venous Etiology Warm oxygenated blood is having trouble getting out to the tissues

Blood is having a hard time getting back to the heart to be recirculated Pulses Weak/thready (absent = very bad sign!)

Generally good (2+ to 3+) Sometimes hard to feel if has excessive edema (3 – 4+ edema) Appearance Skin is dry, flaky, shiny* No edema *Can be shiny in either type

Skin is shiny* Edema May be weeping if has excessive edema (fluid is leaking through the skin) Color Pale (pallor) or cyanosis Skin can have rubor (dark red- purplish color) when in dependent position

Pink/reddened

Temperature Cool/cold Warm Ulcers Pale/dry Red/draining fluid Complications Pain (ischemia) Intermittent claudication

Edema can become chronic Varicose veins Deep vein thrombosis (bad news) Pulmonary embolus (from DVT) – deadly! Treatments (Interventions )

Improve arterial circulation: AHA diet (reduces cholesterol and plaque build-up) Stop smoking (nicotine is a powerful vasoconstrictor!) Statin medications Encourage collateral circulation (with int. claudication: walk until hurts, stop until not hurting, walk again – repeated tissue demand for oxygenated blood will stimulate new arteries to be made) Dangle the limb to promote circulation to the tissues = use gravity!

Encourage venous return: Walk (squeezing action of muscle contraction/relaxation helps move venous blood back up to the heart)

Discourage venous stasis (venous blood does not move much and puts pressure on the veins or is more likely to CLOT!): Reduce standing or sitting for long periods of time CLOT!) Elevate the limb to promote venous return = use gravity!

Consequences Painful Loss of limbs or life possible

Uncomfortable Usually not deadly (except PE)
