Injury Vs Ischemia
Reperfusion injury: Reperfusion injury refers to tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. The absence of oxygen and nutrients from blood during the ischemic period creates a condition in which the restoration of circulation results in leaking from blood vessel the substances that produce damage to tissue - the degraded enzymes create further damage. ...Read moreSee 1 more doctor answer
What is "internal derangement of the knee" mean? Would that term include a previous traumatic med-collateral strain/sprain and/or meniscal injury?
What's the difference between a cerebral vascular accident (stroke) & a transient ischaemic attack (tia)?
Definitive damage: A TIA describes stroke like symptoms that resolve without other intervention within a short timespan, usually less than 1 hour although the classic definition uses 24 hours. A stroke describes irreversible brain tissue damage caused by a lack of blood flow (technically a bleed is also a form of stroke). This damage can be diagnosed definitively on a MRI scan, no such damage can be seen in the tia. ...Read moreSee 2 more doctor answers
What does coronary occlusion acute, arterio-sclerotic cardio vascular disease and acute myocardial infarction mean?
Alot: While mechanisms of injury to these structures may be similar and in many cases treatment may be similar they are very distinct anatomically and in terms of function and healing potential. So it would be important to know the location, type and extent of injury. ...Read moreSee 1 more doctor answer
Yes: The bruit may represent carotid stenosis, plaque blocking the artery. If a piece of plaque or clot breaks off, then it can travel to brain causing cva/stroke. Doppler should reveal nature of bruit. Vascular surgeon may be consulted to do endarterectomy or stent, if merited. ...Read moreSee 2 more doctor answers
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
What is moderate perfusion abnormality of the inferior basal wall suggestive of possible scar vs. Attenuation?
Cause: An eventual brain injury can be due to decreased blood flow (stroke), or an aneurysm (hemorrhage), or low blood sugar or low oxygen (hypoxia). When the term traumatic is used, the cause is a physical injury like being hit hard over the head after falling. Unfortunately any severe brain insult could affect future fnctn quite severely. ...Read more
No: A brain abscess is a medical emergency and is due to a localized brain infection. If it ruptures, meningitis could occur and cause death. Unless there has been an open head injury, trauma does not directly cause infection. Physical injury such as falling and striking the head results maybe in "traumatic brain injury". ...Read more
Ischemia vs MI: Cholesterol plaque develops in the heart arteries. Progressive narrowing - usually greater than 70% - can lead to lack of blood flow to the heart muscle during exercise or rest and causes angina or ischemia. Myocardial infarction is due to the rupture of a plaque which causes a blood clot to form (thrombosis) in the artery blocking blood flow to that area of the heart muscle which then dies. ...Read more
Please translate-Severe tendopathy high grade partial thickness tearing from critical zone to insertion site. Nodular synovitis adhesive capsulitis?
Maybe very serious: Ischemia means an area of the heart is not getting enough blood usually because of a blockage in an artery. The severity depends on whether it is a major artery or not. An intact occurs when the artery is completely blocked and the muscle dies. Angina is the pain felt when ischemia occurs. ...Read more
