Abstract:
Lymphedema is a chronic condition caused by ineffective lymphatic transport that results in edema and skin damage. Distinguishing lymphedema from other causes can be difficult. Lymphoscintigraphy is a simple and noninvasive functional test for the evaluation of the lymphatic system. (99m)Technetium-labeled sulfur colloid is injected intradermally at the interdigital web spaces of the upper/lower limbs. Once injected, the radiolabeled colloid particles travel through the superficial lymphatic channels. Thus, their lymphatic transport is monitored with dual-head gamma camera. The typical patterns of upper and lower limb lymphedema on lymphoscintigraphy are summarized in this section.

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...
