Review the physiologic changes that occur with aging.
- Loss of elasticity in something or other.
Explain the etiology and symptoms of peripheral vascular disease.
- PAD involves progressive narrowing and degeneration of the arteries of the
neck, abdomen and extremities. Regardless of anatomic location, atherosclerosis
is responsible for the majority of cases.
- The leading cause of PAD is
, a gradual thickening of the intima
and media of arteries, which leads to progressive narrowing of the vessel lumen.
- Clinical manifestations occur when the vessel is between 60% and 75%
Discuss the risk factors for peripheral vascular disorders.
- The four most significant risk factors for PAD are cigarette smoking,
hyperlipidemia, hypertension, and diabetes mellitus, which the most important
being cigarette smoking. Other risk factors include obesity, hypertriglyceridemia,
hyperuricemia, family history, sedentary lifestyle and stress. Additional risk
factors under investigation include serum levels of C-reactive protein (CRP),
fibrinogen, ferritin, homocysteine and lipoprotein (a).
Explain methods of preventing arterial and venous disorders.
- To prevent these disorders, one must look at the risk factors for developing these
problems. If you maintain a healthy weight, eat a well balanced diet, get regular
exercise, do not abuse alcohol, do not smoke and control diabetes one is at
significantly lower risk for developing these problems.
Describe the differentiating characteristics of arterial and venous disorders.
Explain the purpose and nursing intervention of diagnostic tests for peripheral
Discuss the medication used in treatment of peripheral vascular disorders
(including dosage, mechanism of action, nursing intervention, and antagonist).
Describe the surgery techniques and their purpose in treatment of peripheral
- Various surgical approaches can be used to improve arterial blood flow beyond
a stenotic or occluded artery. The most common is a peripheral arterial bypass
operation with autogenous (native) vein or synthetic graft material to bypass or
carry blood around the lesion.
- Endarterectomy is opening the artery and removing the obstructing plaque
- Patch graft angioplasty is opening the artery, removing the plaque and sewing a
patch to the opening the widen the lumen
Compare advantages of BK and AK amputations.
