The knowledge that deep vein thrombosis most commonly develops in the calf and then extends proximally 1 – 5 was critical in the development of diagnostic strategies for this condition using compression ultrasonography. Unexpected high prevalence of silent pulmonary embolism in patients with deep venous thrombosis. venous duplex ultrasound is 96% sensitive, 97% specific; operator dependent routine duplex screening is not recommended plethysmography is 75% sensitive, 90% specific AJR Am J Roentgenol 2011;197(3):W503–W507.

Re-evaluation of iliac compression syndrome using magnetic resonance imaging in patients with acute deep venous thromboses. Upper extremity deep vein thrombosis (UEDVT) accounts for approximately 5 to 10 percent of all cases of DVT with incidence increasing due to higher frequency of intravenous catheter use. The ratio of left-to-right–sided DVT was 1.32:1 overall but was greater for proximal thrombi, with a ratio of 2.4:1 for iliac DVT versus 1.3:1 for infrainguinal DVT. Veins of the upper extremity are divided into deep and superficial veins ( Figure 27.1 ).
