Vascular Pathologies Flashcards
(40 cards)
Aneurysm Etiology
congenital defect, weakness in wall of vessel often due to chronic hypertension, connective tissue disease (Marfan Syndrome), trauma, infection
Aneurysm Signs/Symptoms
**Varies based on site
Aortic = asymptomatic except for generalized abdominal/low back pain
Abdomina Aortic= pulsing in/near navel
Cerebral= sudden/severe headache, nausea & vomitting, stiff neck, seizure, loss of consciousness, double vision
Aneurysm Treatment
Antihypertensive meds for hyptertension
Surgery to repair aortic aneurysm- break in vessel wall is replaced with synthetic fabric graft
Angina Pectoris: Stable
Occurs @ predictable level of exertion/exercise/stress, responds to rest/nitroglycerin
Angina Pectoris: Unstable
usually more intense, lasts longer, precipitated by less exertion, occurs spontaneously @ rest, is progressive, or combo of above features
Angina Pectoris: Prinzemental (variable)
occurs due to coronary artery spasm associatedw/ Coronary Artery Disease (CAD)
Angina Pectoris Etiology
inadequate blood floe and oxygenation of heart muscles due to CAD
Angina Pectoris Signs/Symptoms
pressure/ heaviness/ fullness/ squeezing/ burning/aching behind sternum (also felt in neck & back, jaw, shoulders, arms)
difficulty breathing, nausea & vomiting, sweating, anxiety/ fear
triggered by exertion/ strong emotion
subsides w/ rest
Angina Pectoris Treatment
Acute: supplemental O2, notroglycerin, rest
Chronic/ Recurring: long-acting nitrates, beta blockers, calcium channel blockers
Angioplasty w/ stenting of coronary arteries/ coronary artery bypass surgery when meds not effective
Atherosclerosis Etiology
exact cause unknown
may begin w/ damage/injury to inner artery wall from hypertension, high cholesterol, smoking, diabetes
over time fatty plaques and other cell waste build up at site of injury & harden narrowing artery and impeding blood flow
Atherosclerosis Signs/Symptoms
** varies based on severity and artery affected
Coronary arteries: angina pectoris
Cerebral arteries: numbness/ weakness in arms/ legs, difficulty speaking/ slurred speech, drooping face muscles
Peripheral arteries: intermittent claudication
Atherosclerosis Treatment
lifestyle changes: quit smoking, regular exercise, healthy diet, stress management
meds: antihypertensive, anti-platelet, anti-lipidemic agents
surgery: angioplasty, endarterectomy, bypass
Chronic Venous Insufficiency (CVI) Etiology
weak/ damaged valves in veins
Risk factors: age, being female, obesity, pregnancy, prolonged sitting/standing
CVI Signs/Symptoms
leg swelling, varicose veins, aching, heaviness/cramping, itchiness, redness/ skin ulcers of legs/ankles
CVI Treatment
compression stockings + elevation of legs to decrease chronic swelling
varicose vein stripping for persistent leg pain/ skin ulcers due to poor circulation
Cor Pulmonale Etiology (pulmonary artery disease)
pulmonary hypertension form chronically increased resistance in pulmonary circulation
Cor Pulmonale Signs/Symptoms
progressive shortness of breath especially w/ exertion
also fatigue, palpitations, atypical chest pain, swelling in LE, dizziness and syncope
Cor Pulmonale Treatment
supplemental O2 sufficient to maintain SaO2> 90% and/or PAO2> 60 mmHg
may also include diuretics & anticoagulants
Coronary Artery Disease (CAD) Etiology
damage/injury to inner layer of coronary artery
fatty plaques and other cell wastes accumulate @ site of injury
if plaque ruptures, platelets clump to repair artery- which may create blockage = heart attack
Risks: high LDL cholesteral, type 2 DBM, smoking, obesity, physical inactivity, genetics, hypertension, hypothyroidism
CAD Signs/Symptoms
degree of stenosis that produces S/S varies w/ O2 demand
diminished blood flow may = angina, shortness of breath, etc. which may not be felt till >70% of lumen occluded
complete blockage = heart attack
CAD Treatment
Aggressive modification of risk factors = slow progression/ induce regression of existing plaques/restore/improve blood flow
includes: quit smoking, weight loss, heart-healthy diet (low sat. fats/ cholest./ Na), regular exercise, modification of serum lipids, control of hypertension/diabetes
Drugs: antiplatelet, ACE inhibitors, angiotensin II bockers, statins
Surgery: percutaneous angioplasty/ coronary artery bypass graft only for pts at high mortality risk
Deep Vein Thrombosis (DVT) Etiology
any condition impairing normal circulation/ blood clotting
Risks: prolonged bed rest, inherited blood clotting disorder, injury/surgery of veins, pregnancy, cancer, birth control/ hormone replacement therapy, overweight, obesity, smoking
DVT Signs/Symptoms
about 50% of cases are asymptomatic
may show swelling, pain, redness, warmth in affected leg
DVT Treatment
GOAL: prevent blood clot from getting bigger/ breaking loose & causing pulmonary embolism
Meds: anticoagulants, thrombolytics
Prevent: compression stockings to reduce blood pooling in LE
