Chapter 42 Flashcards
What is the incidence of screening-detected AAAs in adults younger than 60 years?
1 per 1000
This indicates a low probability of detection in younger adults.
What is the incidence of AAAs in individuals with risk factors?
May be as high as 10%
Risk factors include older age, male sex, smoking, family history, history of other aneurysms, hypertension, and atherosclerosis.
What is the recommended age range for one-time ultrasound screening for AAAs in men?
65 to 75 years
This recommendation is based on the history of smoking.
Is routine screening for AAAs in women recommended?
No.
Controversial
Routine screening has not demonstrated a survival benefit in women.
How much later do AAAs occur in women compared to men?
About 10 years later
This reflects differences in the onset of the condition between genders.
What are the recommendations from the Society for Vascular Surgery (SVS) for AAA screening in women?
≥65 years with a history of tobacco use or a family history of AAAs
This highlights a focused screening approach based on specific risk factors.
What does the U.S. Preventive Services Task Force recommend for men aged 65 to 75 years?
One-time ultrasound screening
This recommendation is specific for men with a history of smoking.
What is the reimbursement policy for AAA screening by the Centers for Medicare and Medicaid Services?
Reimburses screening for men 65 to 75 who ever smoked and men and women 65 to 75 with a family history of AAA
This policy reflects the prioritization of at-risk populations.
True or False: The rates of rupture and mortality from rupture of AAAs are higher in women.
True
This indicates a significant risk disparity between genders.
What screening method has reduced the risk of AAA rupture and AAA-related deaths?
Ultrasound
Screening combined with repair of AAAs above a certain size threshold is effective.
Risk factors for AAA (7)
older age, male sex, smoking, family history, history of other aneurysms, hypertension, and atherosclerosis.
