Introduction Anatomical variation of duplicated leg veins mainly involves the superficial femoral and popliteal vein. On the other hand, calf deep veins are usually paired. Therefore, deep vein thrombosis of one duplicated vein, with normal duplex scan finding of the other, in the absence of ...

Duplex Ultrasonography of the Lower Extremity When conducting lower extremity DUS, the patient should be supine with a slight outward rotation of the hip and leg. DUS begins at the inguinal crease, where the transducer is placed horizontally over the common femoral artery. A "Mickey Mouse" shape...
Scan protocol for patients with impaired renal function and residual renal function (compare Fig. 1) a. If there was a necessity of evaluating the patients’ central drainage, patients’ AVF/AVG extremity was angulated by 90° besides the thorax in supine position (compare Fig. 1). Patients...
A 69-year-old gentleman complained of constant swelling and induration in a previously revascularized right lower extremity. It was noted, during a routine postop visit, that his right ankle brachial index (ABI) was decreased and the induration in his leg had not subsided. He was referred ...
We see such a wide variety of patients from having no visible veins at all to the very tortuous and raised veins covering much of the lower extremity. Both groups usually experience similar symptoms: heavy, throbbing, and fatiguing legs. In general, patients should undergo a preoperative lower...

Medial calf perforators were detected by observing a vein passing through the deep fascia, which is a very distinct band on the B-scan, and confirming its identity by observing augmented flow on color Doppler imaging after squeezing the calf muscles proximal to the site of examination. The full...
