Can Transient Drop in Blood Pressure in High-Risk Hypertensive Patients Cause Small Cerebral Infarcts?

Figure 1

Representative brain MRI (DWI) scans of patients with multiple acute infarcts. (a) and (b) Group 1: Patient 1: deep infarcts: left corona radiata and right internal capsule infarcts on DWI and ADC map. Cranial and neck MR angiogram was normal. (c)–(e): Group 1: superficial cortical infarcts. Patient 2: (c) right frontal infarcts; the patient also had a small superficial acute infarct in right cerebellum (not shown). Patient 3: (d) and (e) left inferior frontal and right cingulate gyrus acute infarctions. MR angiography showed minor irregularities. (f) Group 3: Patient 4: representative borderzone infarcts. MR angiography showed severe stenosis in right cavernous internal carotid (not shown).
