1

Three layers of the arterial system

Tunica intima
Tunica media
Tunica adventitia

2

Purpose of the lymph nodes

Filtering and phagocytosis
Lymphocyte production

3

Risk factors of PVD

Smoking
Diabetes
High-fat diet
Hypertension

4

Threshold for intermitten claudcation in arteriosclerosis obliterans

50% occlusion of vessel

5

Rest pain occurs when in arteriosclerosis obliterans

80%-90% occlusion of vessel

6

Signs and symptoms of arteriosclerosis obliterans

Diminished or absent pedal pulse
Positive signs of rubor of dependency
Trophic changes (texture, color, shiness of skin, less hair, thickened nails)
Ulcerations

7

Buerger's Disease

Thromboangiitis Obliterans
Affects young male smokers
Inflammatory process starts distal, proceeds proximal

8

Most common forms of acute arterial occlusive disease

Arterial embolism, arterial thrombosis, vasospastic diseases

9

Signs and symptoms of acute arterial occlusive disease

Pain
Pallor
Loss of pulses
Paresthesia
Paralysis

10

Raynaud's syndrome

Spasm of arterioles affect the digits
Cyanosis of digits with cold or emotional upset then there is an intense redness/warmth after vasodilation phase

11

Acrocyanosis

Cyanosis of distal extremities, usually affecting hands/finger or feet and toes
Caused by arterial spasm in the small arterioles
No rebound erythema

12

Erythromelalgia

Bilateral vasodilation affecting extremities, especially the feet
Redness, burning, throbbing sensation, and increased skin temperature

13

Venous thrombosis

Obstruction of the blood flow secondary to collection of coagulated blood

14

Homan's signs (DVT)

Edema, girth of limb
Painful palpation
Painful passive stretch of vein
Warmer to touch
