Surveillance of deep vein thrombosis in asymptomatic total hip replacement patients. Impedance phlebography and fibrinogen scanning versus roentgenographic phlebography

Journal Article · · Am. J. Surg.; (United States)
Nine hundred thirty-seven limbs in 537 patients over the age of 39 years who underwent total hip replacement were studied by roentgenographic phlebography, cuff-impedance phlebography, and iodine-125 fibrinogen scanning. Cuff-impedance phlebography had a sensitivity of only 12.3 percent for thigh thrombi. Fibrinogen scanning had a sensitivity of only 59.1 percent for calf thrombi and 13.7 percent for thigh thrombi. The combined use of the two methods resulted in only a 23.2 percent sensitivity for thigh thrombi and an overall sensitivity of 47.4 percent. We have concluded that in asymptomatic patients, in contrast with symptomatic patients, the combination of cuff-impedance phlebography and fibrinogen scanning is not an effective screening method.
