The goal is to compare the results observed in patients that had both an exercise oximetry and a thallium scintigraphy for lower limb claudication
On our routine pratice, patients suffering claudication (specifically atypical claudication or claudication of doubful vascular origin) have exercise oximetry to prove the vascular origin of pain. If still doubtful (inconsistency of pain and oximetry results) patients are referred for thallium scintigraphy. Our goal is to compare the results issued from these two test

transcutaneous oxygen pressure is measured at the skin level on chest , buttocks and calves during a walking test 3.2 km\*:h 10% slope. From the test result the decrease from rest of oxygen pressure (DROP) index is calculated to estimate muscle ischemia
Muscle thallium fixation is measured immediately after a walking test 3.2 km\*:h 10% slope and at 4 hours after the test. From the test result the difference of late and early radioactivity is calculated at the buttock and calf level and normalized to total body radioactivity to estimate muscle ischemia

RECRUITINGCorrelation of thallium scintigraphy to oximetry results
The coefficient of correlation of DROP values to normalized late to early changes in radioactivity wil be calculated at the calf and buttock level
