The veins and arteries of the upper and lower extremities are examined.  The condition of the walls, blood flow, widening or narrowing of the margin is evaluated.

 Indications:

 The research is addressed to:

 * in case of acute or chronic swelling of the limb/ in order to rule out acute and chronic blood clots and assess their degree of danger/

 * in the case of dilated veins appearing on the leg - to find out the extent of their dilatation and further prognosis

 * palpable formations in different parts of the leg - especially if pulsation is palpated on their surface / to deny the vascular origin or to clarify the connection with the vessels/

 * in the case of pain in the calf or thighs when walking / for the detection of blood circulation insufficiency/

 * to assess the degree of vascular damage in the presence of diabetes

 * after vascular operations, or interventions on vessels/ probing/.
