Acute Ischemic Anoxia
Acute - Sudden Onset: Acute stroke refers to a stroke that has just occurred. Ischemic stroke may be hyperacute (based on sudden onset neurological symptoms and imaging findings, MRI and perfusion study) and potentially treatable, acute (1-7 d), subacute (7-21 d), and chronic (>21 d). ...Read moreSee 1 more doctor answer
Possibly: A transient ischemic attack (TIA) is caused by the transient blockage of a blood vessel in the brain, which causes symptoms (weakness, numbness, changes in vision, difficulty speaking, etc.) because the nerve cells aren't working when the blood vessel is blocked. If the blockage is brief (< 1 hour) there may be no damage. If the blockage lasts longer, damage (a stroke) may occur. ...Read moreSee 1 more doctor answer
Yes: Yes indeed. When neurologic symptoms start suddenly we always considered it an acute stroke. If they pass within few minutes or hours completely, they get labeled tia. If they stay and there are changes on mri, then we call it a stroke. But for all practical purposes, TIA is considered an acute stroke at the onset. ...Read moreSee 1 more doctor answer
Time critical: Within 3 hours of symptoms ( up to 4.4 hours in some cases ) intravenous tpa (alteplase). After that up to 6 hours, intraarterial tpa (alteplase) through a catheter in the artery to the brain. Up to 8 hours can use special devices to pull clot out of vessel to brain. These procedures usually done at stroke centers. ...Read moreSee 1 more doctor answer
Yes: If ct of brain reveal no bleeding and if the pt. Is in the window period ( less than 4.5 hours from symptoms )to receive fibrinolytics ( tpa (alteplase) or others) this is going to break the clot and restore the circulation avoiding serious neurological damage.Aspirin is started 24. Hrs later after tombolytics. For DVT prevent. Anticoagulants should be used except when hemorrhagic transformation is present. ...Read moreSee 1 more doctor answer
What is included in an assessment of a geriatric patient who has possibly experienced an acute ischemic stroke?
Stroke: A thorough stroke assessment will include medical imaging to include brain, carotid and heart in trying to understand the mechanism of the stroke, chronic conditions assessment and risk factors modification. Physical and occupational therapy, speech and swallow evaluation are also completed and a possible recommendation for short term rehab may be made. Treatment is mostly supportive otherwise. ...Read more
If an MRI shows infarcts as well as periventricular ischemic changes does this mean a person has had an actual stroke rather than just a tia?
EKG shows normal sinus rhythm, no acute Ischemic changes and poor R wave progression. What does that mean?
PRWP: PRWP or poor R wave progression can be a sign of a few things: most common problem I see is artifactual: simply a matter of suboptimal electrode placement of the EKG either due to sloppy technique or else breast tissue (in women). PRWP can also be a sign of a previous anterior wall MI or heart attack. Lastly, some conduction abnormalities such as left anterior fascicular block can cause this ...Read more
