[Radioisotope diagnosis of postoperative deep-vein thrombosis of the leg in oncological patients].

The authors have studied the frequency and characteristic features of postoperative thrombosis of profound crural veins (PTPCV), using the method of radioindication with fibrinogen J125. Among 80 oncological patients PTPCV), was found in 47 (58.7%). It is noted that PTPCV in 92% of cases developed during 5 days postoperatively, bilateral involvement is more frequently observed (70.2%), and in 28.7% of cases thrombosis involved the upper crural third. Clinical signs of PTPCV were revealed only in 44% of cases and, on the average, 2 days following the onset of the thrombotic process. Radioindication of PTPCV with fibrinogen J125 is a simple, early and precise method of establishing the diagnosis of theis postoperative complications.
