Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal is to compare the results observed in patients that had both an exercise oximetry and a thallium scintigraphy for lower limb claudication

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Interventions

exercise oximetry

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

Intervention Type DIAGNOSTIC_TEST

thallium scintigraphy

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

Intervention Type DIAGNOSTIC_TEST
