Comparative value of noninvasive testing for diagnosis and surveillance of deep vein thrombosis
This is a prospective analysis of 351 patients in two distinct groups undergoing ascending phlebography, impedance plethysmography (IPG), and/or phleborheography (PRG) within the same 24-hour period. One hundred twenty patients also had a /sup 125/I-fibrinogen uptake test (RFUT). The two patient groups consisted of the following: those patients evaluated because of suspicion of deep vein thrombosis (DVT) (diagnostic) and those patients at high risk for postoperative DVT (total joint replacement) who had routine noninvasive testing and ascending phlebography (surveillance). The overall sensitivities for IPG and PRG were significantly better in the diagnosis group (71% (69 of 97 patients) and 78% (82 of 105), respectively) compared with the surveillance group (20% (14 of 71) and 27% (17 of 63), respectively) (p less than 0.0001). The sensitivities for IPG and PRG detecting proximal (A/K) thrombi was 83% (68 of 82 patients) and 92% (79 of 86) in the diagnosis group compared with 32% (11 of 34) and 33% (9 of 27) in the surveillance group (p less than 0.0001). Although there was no difference in overall incidence of DVT between the diagnosis group (56%, 118 of 212 patients) and the surveillance group (55%, 76 of 139), the results can be explained by the difference in A/K thrombi (84% (99 of 118) and 47% (36 of 76)) (p less than 0.001) and occlusive A/K thrombi (84% (58 of 69) and 23% (7 of 31)) (p less than 0.0001), respectively. Of the patients with A/K thrombi, 97% (67 of 69) in the diagnosis group had hemodynamically detectable thrombi compared with only 48% (12 of 25) in the surveillance group (p less than 0.001). Combining the RFUT with the noninvasive studies for surveillance significantly improved the sensitivity for both A/K and distal thrombi.
