I NEED A PATHOPHYSIOLOGY FOR PT WHO HAD CVA AFTER A MOTOR VEHICLE ACCIDENT. PT HAD HAS HISTORY OF DIABETES, HYPERTENSION, DYSLIPIDEMIA AND TIA?

Hmmm.. Pretty cool question. You are either a bushy tailed medical student or an ambulance chasing JD who graduated with an MD but got smart and started a legal practice instead! HA! Impossible to say from the given data without you saying first WHAT type of stroke it was...Gotcha! HA! The risk factors are mostly in favor of small vessel ischemic except the TIA which tilts toward embolic. Your turn---
Unclear question. The patient has a number of risk factors for a stroke, with or without the motor vehicle accident. Please clarify your question.
Multiple risk factor. The patient has every risk factor for stroke other than smoking. The patient also had prior TIA (some people refer to as mini-stroke). While hospitalized, the patient should have an echocardiogram performed and placed on heart monitor to evaluate for atrial fibrillation.
Cause of stroke. Hi. The most likely cause of the stroke does not make it the cause of the stroke; this is a probability argument. The most likely given the risk factors is ischemic due to atherosclerosis; this would also account for the prior TIA. Of course, hemorrhagic stroke due to aneurysm rupture from hypertension or aneurysm rupture secondary to head trauma (MVA) are possible, but probably less likely. .
