Evaluation of buttock claudication with hypogastric artery stump pressure measurement and near infrared spectroscopy after abdominal aortic aneurysm repair

Abstract

An HBI below 0.65 may be a predictor of BC after AAA repair. NIRS appears to be a useful noninvasive method for evaluating BC after AAA.

Hemodynamic Consequences of Internal Iliac Artery Occlusion Following Endovascular Abdominal Aortic Aneurysm Repair Assessed by Near-Infrared Spectroscopy

“…But in order to obtain an individual clinical diagnosis this type of a test was less convincing. We were unable to reproduce the findings reported by Sugano et al [10], demonstrating a sensitivity and specificity of 100%, respectively, in eight claudicants and ten asymptomatic gluteal sides. The even lower accuracy found in group B using recovery time stresses the limitations of NIRS usage as a diagnostics test for IIA occlusion/gluteal claudication.…”

“…A cut-off value of 240 seconds, as suggested by Sugano et al, was used to determine sensitivity and specificity [10] and a ROC-curve analysis was performed to find an optimal cut-off value.…”

“…Graphs were printed in GraphPad Prism 5.0 software (GraphPad Software, San Diego California USA). Using a cut-off value of 240 seconds, as suggested by Sugano et al [10], the "occluded" sides was separated from the "patent" sides, with a sensitivity and specificity both of 71%.…”

“…The pelvic circulation has been examined by transcutaneous oxygen pressure (tcp02) and near infrared spectroscopy (NIRS) [8][9][10][11][12]. The latter technique has proven useful for assessment of changes of regional cerebral oxygen saturation [13], in vascular surgical patients [14] and in evaluation of patients with peripheral arterial disease [15].…”

“…The latter technique has proven useful for assessment of changes of regional cerebral oxygen saturation [13], in vascular surgical patients [14] and in evaluation of patients with peripheral arterial disease [15]. Sugano et al [10] applied NIRS to evaluate the gluteal oxygen supply following an open operation for AAA with ligation of the IIA. NIRS sensors were applied over the gluteal regions.…”
