Abstract:
A 38-year-old man without skin rash was admitted to our hospital for recurrent cerebral infarctions. Cerebral angiography revealed vertebral artery stump syndrome (VASS), and a high varicella-zoster virus (VZV) antibody index suggested VZV vasculopathy. Treatment with aspirin and anticoagulants was initiated, along with intravenous acyclovir and methylprednisolone sodium succinate. No further cerebral infarction was observed. Clinicians should be aware that VZV vasculopathy may underlie ischemic stroke in young adults and VASS even in the absence of a rash. An early diagnosis and appropriate treatment have contributed to favorable clinical outcomes.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
