Question Answer
Intracranial aneurysms (IA) occur in _____% of the general population?3.2%
Only 1: ____ to ____ of the 1 million poeple with aneurysm will suffer from rupture each year?200; 400
Although uncommon, rupture of an AI is often fatal w/ mortality rate of ___ to ___% and survivors are often left with significant disability?50; 60
The mean age of presentation of subarachnioid hemorrhage (SAH) is ___ to ___ years, with an increased incidence in what gender?50; 60; female
Acute SAH tends to affect individuals at peak productivity, resulting in what?significant physical, emotional and economic impact
Does screening high-risk patients help to reduce the risk of rupture?yes
Some evidence suggests that screening individuals w/ only one affected first-degree relative may be reasonable, however, this is not widely accepted. Those with > 2 affected first-degree relatives have an estimated _____% risk for having an intact IA, so screening this population may be cost-effective?8.7%
*** According to guidelines published in 2012 by the American Heart Association / American Stroke Association (AHA / ASA) and the European Stroke Association, patients with > 2 family members having had an IA or SAH should be offered aneurysmal screening by what imaging studies?computerized tomographic angiography (CTA) OR MRA
*** In addition, the AHA / ASA recommends that patients with a hx of autosomal dominant ______ kidney disease, particularly those w/ a family hx of IA, those with ______ of the aorta, and patients with what type of dwarfism should be offered screening for IA by CTA or MRA?polycystic; coarctation; microecephalic osteodysplastic primodial dwarfism
Patients with previously treated acute SAH may benefit from screening for what?new or enlarging aneurysms
What is the suggested screening interval fro those at risk?7 years
What is a common cause of nonaneurysmal subarachnoid hemorrhage? Does it increase the patient's likelihood of harboring an aneurysm?1) trauma 2) no
While smoking is a risk factor for acute SAH, do the guidelines support screening asymptomatic patients in this population?no
*** List the modifiable risk factors for the prevention of SAH?1) smoking cessation 2) adequate control of HTN
*** Growth of an IA may increases the risk of ______, thus intermittent follow-up studies should be considered?rupture
*** SUMMARY = Although uncommon, rupture of an IA is often fatal with a mortality rate of _____ to _____%. Survivors often have signfiicant _______?50; 60; disability
*** SUMMARY = Scrrening of appropriate patients can allow for intervention that may reduce the risk for what?rupture
*** SUMAMRY = What patient types should CTA or MRA be offered for screening purposes?1) hx of autosomal dominant polycystic kidney disease 2) those with a family hx of IA 3) those with coactation of the aorta 4) patients w/ microcephalic osteodysplastic primordial dwarfism
