[Desympathyzation of arteries in blood circulation disorders of upper extremities]
Abstract:
Results of surgical treatment using the arteries desympathization in 47 patients with the upper extremities (UE) blood circulation disorder were studied. Artheriolysis was performed in 21, periarterial sympathectomy--in 26 patients. For obliterating disease 19 patients were operated, for Raynaud syndrome--9, for the traumatized vessel diseases--8, for the thoracic outlet compression syndrome--11. Desympathization of arteries secures significant improvement of blood circulation in distal parts of UE in terms up to 1 mo in 95.7% of the patients operated on.

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...
