Also, unlike ultrasonography of deep venous thrombosis, the procedure focuses mainly on superficial veins. Also, unlike the arterial ultrasound examination, blood velocity in veins has no diagnostic meaning. Veins are a draining system similar to a low pressure hydraulic system, with a laminar flow and a low velocity.
Unlike arterial ultrasonography, venous ultrasonography is carried out with the probe in a transversal position, (perpendicular to the vein axis), displaying cross-sections of the veins. [4] All collateral veins are better detected this way, including perforator veins, but of most importance is the detection of venous thrombosis.
Ultrasound is indicated if superficial phlebitis involves or extends into the proximal one-third of the medial thigh, there is evidence for clinical extension of phlebitis, lower extremity swelling is greater than would be expected from a superficial phlebitis alone or diagnosis of superficial thrombophlebitis in question.
Paget–Schroetter disease (which evolved from a venous thoracic outlet syndrome) is a form of upper extremity deep vein thrombosis (DVT), a medical condition in which blood clots form in the deep veins of the arms. These DVTs typically occur in the axillary and/or subclavian veins. [1]

Tying off the vein with an endoscope. Valve repair (experimental) Valve transposition (experimental) Hemodynamic surgeries. Venous insufficiency conservative, hemodynamic and ambulatory treatment (CHIVA method) is an ultrasound guided, minimally invasive surgery strategic for the treatment of varicose veins, performed under local anaesthetic.

A peripherally inserted central catheter, or PICC line (pronounced "pick"), is a central venous catheter inserted into a vein in the arm (via the basilic or cephalic veins) rather than a vein in the neck or chest. The basilic vein is usually a better target for cannulation than the cephalic vein because it is larger and runs a straighter course ...
The vein can be identified near the saphenous ostium by a typical ultrasonographic image the so-called Mickey mouse sign (the 2 ears will be the GSV and the ASV, the head is the common femoral vein). When the ultrasonography is performed, we can see it running across the anterior face of the thigh in a plan outside the femoral vessels, the GSV ...
