Abstract: Prosthetic vascular graft infection is a relatively uncommon complication of peripheral vascular surgery. We retrospectively analysed technetium-99m-d,l-hexamethylpropylene amine oxime (99Tcm-d,l-HMPAO) labelled leukocyte scans of 21 patients with a suspected vascular graft infection. Operative findings, bacteriological cultures, radiological findings or clinical follow-up were used to confirm the diagnosis. We found eight true-positive and six true-negative cases. There were no false-positive scintigraphic diagnoses. The false-negative rate was 33% (n = 7). Our results show a sensitivity of 53%, a specificity of 100% and an accuracy of 66%. The conclusion is that a negative 99Tcm-d,l-HMPAO-labelled leukocyte scan is of limited value in ruling out a vascular graft infection. A combination of computed tomography (CT-scan) and a 99Tcm-d,l-HMPAO-labelled leukocyte scan is probably the most efficient way of diagnosing a vascular graft infection.
