Estudios vasculares venosos no invasivos de extremidades superiores e inferiores

Noninvasive vascular studies of the upper and lower extremities veins are used primarily to establish the level or degree of obstructive disease and are necessary if there are findings and symptoms of this and / or the patient is a candidate for invasive treatment of their condition. There are two types of venous studies: • Physiological studies – these studies are functional measures including analysis of doppler waveform in response to compression segment, blood pressure measurements, pressure measurements of transcutaneous oxygen plethysmography volume segment determination provocation tests apply and determinations of reactive hyperemia. • The duplex scanning the upper and lower limbs is an ultrasonic scan where images and structures in two dimensions and in real time are shown, also it includes a spectral analysis with the blood flow velocity. <a id="
