Abstract:
Carpal tunnel syndrome presenting as a trophic disorder in the hand is unusual. We report the case of a 66 year old man in whom nerve conduction tests confirmed compression of the median nerve in the carpal tunnel, and vasospasm in the corresponding area was demonstrated by arteriography for, we believe, the first time. Simple decompression of the carpal tunnel brought about total recovery. The mechanism of the autonomic disorders found in carpal tunnel syndrome remains controversial. The clinical case that we report objectively demonstrates the vasospasm caused by the compression of the autonomic fibres of the median nerve.

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...
