Abstract:
Developmental venous anomalies (DVAs) of the central nervous system are an exaggeration of the normal venous collector system, not a vascular lesion. They may be associated with many vascular and nonvascular processes with the nervous system including tumors, demyelinating lesions, arteriovenous malformations (AVMs), dural AVMs, cavernous malformations, and vascular lesions of the head, face, and eye. The instigating factors involved are not completely understood. The primary clinical significance of DVAs is that planned or inadvertent occlusion during treatment of associated lesions frequently leads to venous infarction of the surrounding normal brain.

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 the...
