Distinction by radioisotope technique of a subgroup with increased thrombophilic potential among patients submitted...

Deep vein thrombosis (DVT) detectable by the 99mTechnetium-labeled plasmin test developed in 13 (37%) of 35 sequentially studied patients, all above 40 years, undergoing elective major abdominal surgery. Ten of the 13 patients with DVT had an abnormal pulmonary perfusion scintigram, suggesting pulmonary embolism (PE), but only three had clinical evidence of thrombotic disease.
