Answer

Essential components of workup in posterior cerebral artery (PCA) stroke depend on the patient's age, stroke risk factors, and prior medical history. For example, studies used to evaluate the older patient (whose stroke is associated with cardiovascular disease) may include those that assess (1) severe anemia or volume depletion that can cause, worsen, or confound cerebral ischemia; (2) early infection as a result of aspiration; and (3) baseline coagulation status in case treatment involves heparin, warfarin, or thrombolysis.
