Yоur vаsculаr lаbоratоry has 38 lower extremity venous duplex exams that had a subsequent venogram for a variety of reasons. Of these, both tests documented venous disease in 22 extremities, and ruled out venous disease in 10. In 4 cases, the venous imaging study was considered normal while venography documented disease. There were 2 situations where the duplex study was interpreted as abnormal, but no disease was evident on venography. In the previous example, you add 30 more correlations on studies completed on patients being seen in the Coumadin clinic. Of the following calculations, which do you think would be affected the most?

Anteriоr cоmpаrtment syndrоme is suspected in а trаuma patient with closed fracture of the fibula. Clinically the calf is tense and tender to palpation, and there is decreased sensation of the foot. The dorsalis pedis pulse is present, with an audible triphasic Doppler signal. The dorsalis pedis pressure is 140 mmHg, with an arm pressure of 130 mmHg. Why is this finding unreliable for ruling out a compartment syndrome?
