PVS Flashcards
MC arteries
-carotid bifurcation
-proximal LAD
-proximal renal arteries
-abdominal aorta
-progress distally
-atherosclerotic
homocysteine
-high levels is a risk factor
-high meat diet
-assoc with low levels of B6,B12, folate, and renal ds
peripheral venous system
-superficial venous thrombosis poses risks -> 1/3 DVT or PE
-DVT in upper limbs- 10% -> central venous catheters, cardiac pacemakers, defibrillators
-deep veins- 90% of blood
-superficial- great/small saphenous
-anastomotic- connect 2 superficial
-perforating- connect superficial to deep
-1 way valves
anatomy of the arteries
-atherosclerosis- chronic inflammation
-LDLs in intima
-atheroma- fatty layer forms
venous insufficiency
-varicose veins
-defective valves
-overstretched due to excessive or persistent pressure- venous HTN
-inability to drain blood
-venous stasis- pain
-venous dermatitis
-heavy feeling
-tired legs at end of day
-pulses- normal
-edema
-darkening, hemosiderin deposits
-chronic ulcers
lymph
-epitrochlear- medial hand and axilla
-vertical inguinal- leg
-horizontal inguinal- abdomen, butt, genitalia, anus, perianal area, vagina
artery with pain
-butt/hip- aortoiliac
-ED- iliac-pudendal
-thigh- common femoral or aortoiliac
-upper calf- superficial femoral
-lower calf- popliteal
-foot- tibial or peroneal
-post prandial- celiac, SMA, IMA
leriche’s syndrome
-aortoiliac occlusive disease
-1. claudication
-2. ED
-3. decrease distal pulses
PVD
-central venous catheters- discomfort, pain, numb, weak
-virchow’s- hypercoagulability, venous stasis, endothelial injury
screening
->65 or > 50 with hx of DM or smoking or leg sx with exertion, non healing wounds
-renal artery ds, AAA
-60% have coexisting CAD or cerebral artery ds
-majority asymptomatic- claudication in only 10%
-ABI
-same CVD risk as MI pts
intervention
-supervised exercise programs
-tobacco cessation
-tx of hyperlipidemia
-DM and HTN control
-antiplatelet agents
-meticulous foot care and well fitting shoes
-selected cases revascularization
renal artery disease
-higher risk:
-end stage renal ds, CHF, DM, HTN
-fibromuscular dysplasia- women > 40
-suspect in:
-HTN <30
-severe HTN at age of >55
-accelerated/sudden worsening of previous controlled HTN
-resistant- 3 drugs
-malignant HTN- acute end organ damage
-worsening on renal function or after ACE/ARB
-small kidney
-unexplained pulmonary edema, especially with poor renal function
-US, MRA, CTA
AAA
-risk- older age, male, smoking, family Hx
-hx of vascular aneurysms, taller, CAD, CVA, atherosclerosis, HTH, dyslipidemia
->3cm
-5.5- risk of rupture
-screen:
-men 65-75 who smoked more than 100 cigs
-also men who dont smoke
-dont screen women who have never smoked
-US
ulcer
-arterial- lateral
-venous- medial
1+ pulse
-diminished, weaker
-suggest arterial insufficiency
