Value of indium-111-labeled leukocytes scintigraphy in patients after arterial reconstructive surgery.

The study was performed to evaluate the diagnostic value of Indium-111-leukocytes scintigraphy in arterial prosthetic infection. Scintigrams were performed in 19 patients in two groups. Group A consisted of 11 patients, where ten days after uncomplicated graft implantation, an Indium-111-scintigraphy was performed. Group B consisted of 8 patients, where we suspected an infected arterial graft. In group A we had one false-positive scan and in group B one false-negative scan. This gives an accuracy of 89%, a sensitivity of 87% and a specificity of 90%. These results indicate that Indium-111-leukocytes scintigraphy is a favourable test to detect a vascular graft infection.
