MEDRADSC 3C03 Lecture Notes - Lecture 26: Aspirin, Thrombus, Embolism
Document Summary
Whether talking about any 3, the more the patient exhibits, the more likely the patient experiences thrombus formation. Each alone is a risk factor for thrombosis. Occlusive: blocked; blockage of the vessel = tissue downstream is not perfused = necrosis unless there is collateral circulation. Non-occlusive: blocking a portion of the vessel, blood can flow around the thrombus; s&s may not be as acute as occlusive. Generally, not for peripheral veins bc of their caliper - if we form any venous intervention (specifically dvt), we really just look at deep veins & targeting those regions. Focus on ivc filters - preventing strokes, not fixing the reasons for the clot - just a method for protecting patient from clots that could be thrown/broken apart. Patient cannot have anticoagulants yet have a thrombus. Are high risk for a clot & cannot be screened, monitored, or treated. Controversial: filter in patient who is high risk but do not have a dvt (prophylactic)
