Causes Of Altered Tissue Perfusion
Shouldn't: A myocardial perfusion scan shouldn't cause a cough. Perhaps a mild allergy is present but this is extremely rare. A ventilation-perfusion scan may cause a cough primarily due to the ventilation scan component. People who get these tests often have underlying medical problems associated with cough, and that would be the primary reason for the cough, not the scan. ...Read moreSee 1 more doctor answer
The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
See below: The primary way to assess overall health (reflecting perfusion) would be to check the vital signs. A common way to assess peripheral perfusion is to check the color of the tissue under the fingernails after squeezing. Peripheral pulses help assess tissue perfusion. Usually the shock is treated first prior to performance of a scan such as a brain perfusion scan or myocardial perfusion scan. ...Read moreSee 1 more doctor answer
Would a low diastolic at exercise cause lower coronary perfusion? Say 120/50 or 120/40? Comparing to 120/80 etc?
No: Coronary blood flow depends on the caliber of the blood vessels as well as the pressure. This is a good BP for anyone. How you feel is important too. ...Read more
What's the care plan for patient with nephrotic syndrome and diagnosed with ineffective tissue perfusion , renal?
Depends: It depends on if it is steroid responsive or not. Treatment can vary - it needs to be individualized. ...Read more
Cerebral perfusion: Nothing is 'supposed' to cause poor cerebral perfusion. When cardiac function becomes poor enough to decrease cardiac output and or blood pressure enough to perfuse the brain adequately, then the patient is in serious trouble. This usually happens only with severe cardiac dysfunction and often has associated cerebral vascular disease. ...Read more
I accidently spent 30 minutes with a patient during a myocardial perfusion scan while I am 3 weeks pregnant. Will it cause problems for my baby?
No: I work in a cardiac cath lab and my nurse was pregnanat and wore a badge outside her lead apron. It received essentially zero radiation despite hours and hours of exposure. The key is the inverse square law. The radiation drops off very quickly as you move inches away from the source (the patient's bloodstream). You have had a negligible exposure - you get more on a sunny day! ...Read moreSee 2 more doctor answers
What does this mean: myocardial perfusion imaging adversely affected by soft breast tissue attenuation
Imaging Artifact: Soft tissue attenuation in the breast is a common artifact in myocardial perfusion imaging. It may artifactually affect the depiction of activity in the myocardial wall. If perfusion defect is seen on both stress & rest images and normal wall motion & wall thickness shown on ecg-gated spect then apparent fixed defect is an artifact of attenuation instead of an area of myocardial infarction. ...Read more
Can significant valve leakage (causing systemic perfusion velocity disturbances) happen sporadically, such that a 20-minute echo wouldn't show it?
Anything's possible: But I think it highly unlikely a 20 min. echo done by a GOOD tech & read by a decent cardiologist would completely miss & not even be suspicion for valve leakage that was SIGNIFICANT based on clinical grounds which should be obvious for symptoms of heart failure or pulmonary compromise depending on which valve we're talking about. HIGHLY UNLIKELY. More questions? www.healthtap.com/dr-drsaghafi ...Read more
