Peripheral Vascular Exam Flashcards
What is inspected on the upper extremity in the peripheral vascular exam?
- size
- symmetry
- swelling
- venous pattern
- color
- texture
- nail beds
What is inspected on the lower extremity in the peripheral vascular exam?
- size 2. scars
- symmetry 4. color
- swelling 6. nail beds
- rashes
- ulcerations
- texture
- venous enlargement
- unusual pigmentation
- hair distribution
What pulses need to be palpated?
- carotid
- brachial
- radial
- ulnar
- femoral
- popliteal
- dorsalis pedis
- posterior tibial
Where is 90% of the venous return in the lower extremities?
Deep veins, well supported by surrounding tissues
What are the 3 most important LE veins?
- Femoral
- Great saphenous
- SMall saphenous
What are characteristics of veins?
- Deep, superficial and communicating veins all have one way valves
- Blood flows from the superficial to deep system toward the heart
- Muscles contract and blood is squeezed upward against gravity
- Competent valves keep it from falling back again
What lymph nodes are accessible on exam?
- Only superficial lymph nodes are accessible on exam:
A. Cervical
B. Axillary
C. Epitrochlear (located on medial surface of arm about 3 cm above elbow)
D. Inguinal nodes (normal size can be 1-2 cm)
-Horizontal group (below inguinal ligament)
-Vertical group (near upper part of saphenous vein)
What does assymmetric hair pattern indicate?
Arteriole issues
How are pulses described?
0: Absent, unable to palpate \+1: Diminished, weaker than expected \+2: Brisk, expected \+3: Increased \+4: Bounding
What do diminished pulses indicate?
- partial or complete occlusion proximally
A. Example: If femoral pulse absent occlusion is aortic or iliac and all pulses distally are affected
What does a widened pulse indicate?
aneurysm (abdominal aorta)
What is the most common cause of arterial occlusion?
- Most common cause is arteriosclerosis obliterans in which fatty plaques impede blood flow
Where does arterial occlusion most commonly occur?
- Most often occurs in the thigh
2. Decreased or absent foot pulses suggest occlusive disease of the lower popliteal artery
What condition is asst. with arterial occlusion?
Diabetes
What are the symptoms of arterial occlusion?
Six P’s of ischemia
- Polar (cold): typically first notable symptom
- Pain: absent in 20% of cases due to prompt onset of anesthesia or paralysis
- Pallor: replaced by mottled cyanosis in a few hours
- Paresthesia: light touch lost first followed by other sensory modalities
- Paralysis/Power: further progression of ischemia, indicative of severity
- Pulselessness
