During the inclusion period, 126 patients were eligible for study enrollment. A total of 27 patients was excluded from the analysis. Contrast venography could not be performed in 16 patients because of medical or technical reasons (failure to obtain venous access, n = 10; renal failure, n = 3; pregnancy, n = 2; and iodinated contrast allergy, n = 1). Another 5 patients were excluded because of logistic reasons, and 2 patients declined to provide informed consent. Therefore, venography could not be performed in 23 of 126 patients (18%). In 1 patient, duplex color ultrasonography was not performed because of logistic reasons. Finally, results of duplex color ultrasonography were indeterminate in 3 patients, resulting in a conclusive rate of 98%. A flow diagram of patients is provided in Figure 1.
