Q

What are the 3 categories of peripheral artery disease

A
  1. Intermittent Claudication: Symptoms occur only during physical activity
  2. Asymptomatic Disease: Asymptomatic because activity level never exceeds the threshold
  3. Limb-threatening Ischemia: Clinical syndrome, chronic, advance limb ischemia, rest pain, non-healing ulceration, gangrene

Q

What disease cause obstruction

A

Mainly atherosclerosis, but can be nonatherosclerotic:
1. Buerger disease: Blood vessels inflamed causing blockage (usually males over 45 who smoke)
2. Vasculitis: Blood vessel inflammation resulting in thickening and restricted blood flow to organs resulting in tissue damage
3. Fibromuscular dysplasia: Primarily affects females that causes stenosis, dissection, or aneurysm (impacts walls of arteries)

Q

What is artherosclerosis

A

IT is a chronic, slow, progressive disorder that causes plaque to accumulate resulting in loss of elasticity, stenosis, and and obstruction. The plaque can burst resulting in a thrombosis resulting in ischemia

25
What are paralysis characteristics of a thrombus/embolus
26
What are paresthesia characteristics of a thrombus/embolus
27
What are pressure characteristics of a thrombus/embolus
28
What are poikilothermia characteristics of a thrombus/embolus
29
What is a fasciotomy and why are they performed
They are an incision to the skin used to relieve pressure
30
What is a 4 compartment fasciotomy and what is the process to closing it
Incision made through skin and fascia (medial and lateral) to decrease pressure in the muscle compartment that is then left open until swelling decreases. Once swelling decrease can close one or both sides and if need and skin graft can be used to achieve closure
31
What is acute compartment syndrome and why does it occur
Serious/emergent that is caused by increased intercompartment pressure which decreases perfusion pressure to tissues within that compartment. It occurs from fractures, crush injuries circumferential burn, electrical injuries, hematomas, revascularization procedures, cast, circular dressings.
32
What is chronic venous insufficiency and its causes
33
What are 6 symptoms of chronic venous insufficiency
34
Compare and contrast arterial vs venous disorders in terms of clinical findings
35
List some characteries of diabetes mellitus and how its related to microvascular disease
36
Describe retinopathy (microvascular disease)
37
Describe nephropathy (microvascular disease)
38
Describe neuropathy (microvascular disease)
39
What are the 4 major types of neuropathy
40
What are the 3 primary areas affected by autonomic neuropathy
41
What are 6 characteristics of peripheral neuropathy
42
List 6 characteristics of diabetes mellitus and its link to peripheral vascular disease
43
What are 7 implications to sensory loss
44
What are 3 implications of motor loss
45
What are 3 education pieces if motor loss occurs
46
What is and causes the diabetic foot
Sensory, motor, and autonomic consequences of neuropathy lead to diabetic foot and neuropathic ulceration
47
What is a neuropathic ulceration
48
What is osteomyletis
Infection of the bone that spreads from nearby tissue or blood stream
