N2 - Background: Provoked gluteal claudication is a known risk after endovascular aortic repair (EVAR). Lowered gluteal muscle oxygenation (SgmO2) may be demonstrated by near-infrared spectroscopy (NIRS).Purpose: To evaluate NIRS-determined SgmO2 in EVAR patients.Material and Methods: NIRS-determined SgmO2 was used in an observational study design (n = 17). From the ambulatory setting, seven EVAR patients were included with reported gluteal claudication from medical records. In 10 patients scheduled for EVAR, SgmO2 was measured before and after the procedure. NIRS sensors were applied bilaterally on the gluteal region. Treadmill walking (12% incline, 2.4 km/h) was introduced to stress gluteal muscles.Results: A reduced SgmO2 with regional side difference (P < 0.05) was noted in all 10 patients following EVAR and four reported gluteal claudication. In patients with gluteal claudication (n = 7), treadmill decreased SgmO2. The time to recover the SgmO2 was prolonged for tissue exposed to occluded hypogastric artery (median = 512 s, range = 73-1207 s vs. median = 137, range = 0-643 s; P = 0.046).Conclusions: EVAR affects gluteal muscle oxygenation. NIRS could be used to assess whether gluteal claudication is related to lowered SgmO2.
