Résumé
Calf pain is the most frequent symptom of arterial claudication. We hypothesized that patients with self-reported isolated calf claudication have frequent exertional non-calf symptoms during objective laboratory testing, and that many would show not only distal, but also proximal ischemia. We retrospectively analyzed the patients referred since 2016 for exercise transcutaneous oxygen pressure (Ex-tcpO Exertional symptoms on a treadmill occurred in 526 (90.1%) of the 584 patients analyzed (65.6 ± 11.4 years old), with 391 (74.3%) of these symptoms affecting only the calf. Isolated calf ischemia with or without symptoms was found in only 139 (23.8%) patients. Overall, among the 584 patients self-reporting isolated calf symptoms, a perfect concordance between symptoms on a treadmill and Ex-tcpO Our study demonstrated that patients self-reporting exertional limb pain strictly limited to the calf may also have non-calf claudication on a treadmill and frequently show not-only-calf ischemia. These observations are important when planning reeducation or when studying the tissue consequences of ischemia in patients with claudication.

BACKGROUND AND AIMS
Calf pain is the most frequent symptom of arterial claudication. We hypothesized that patients with self-reported isolated calf claudication have frequent exertional non-calf symptoms during objective laboratory testing, and that many would show not only distal, but also proximal ischemia.
METHODS
We retrospectively analyzed the patients referred since 2016 for exercise transcutaneous oxygen pressure (Ex-tcpO
RESULTS
Exertional symptoms on a treadmill occurred in 526 (90.1%) of the 584 patients analyzed (65.6 ± 11.4 years old), with 391 (74.3%) of these symptoms affecting only the calf. Isolated calf ischemia with or without symptoms was found in only 139 (23.8%) patients. Overall, among the 584 patients self-reporting isolated calf symptoms, a perfect concordance between symptoms on a treadmill and Ex-tcpO
CONCLUSIONS
Our study demonstrated that patients self-reporting exertional limb pain strictly limited to the calf may also have non-calf claudication on a treadmill and frequently show not-only-calf ischemia. These observations are important when planning reeducation or when studying the tissue consequences of ischemia in patients with claudication.
