    Summary

    Leg pain during exercise relieved by rest may mimic vascular intermittent claudication. However, lumbar spinal stenosis causing neurogenic claudication is often the actual condition. Differentiating these is crucial for correct diagnosis and treatment.

    Area of Science:

    • Neurosurgery
    • Vascular Surgery
    • Orthopedics

    Background:

    • Leg pain during exercise relieved by rest is commonly attributed to vascular insufficiency (intermittent claudication).
    • Accurate differentiation is essential for appropriate patient management.
    • Misdiagnosis can lead to delayed or incorrect treatment.

    Purpose of the Study:

    • To highlight the diagnostic challenge in differentiating vascular intermittent claudication from neurogenic claudication.
    • To emphasize lumbar spinal stenosis as a significant mimic of vascular intermittent claudication.
    • To discuss the clinical experience in distinguishing these conditions.

    Main Methods:

    • Review of clinical cases presenting with exercise-induced leg pain relieved by rest.
    • Analysis of diagnostic challenges in differentiating vascular and neurogenic causes.
    • Experience-based insights from a neurosurgery department.

    Main Results:

    • Lumbar spinal stenosis (neurogenic claudication) frequently presents similarly to vascular intermittent claudication.
    • Clinical presentation alone can be insufficient for definitive diagnosis.
    • Diagnostic difficulties arise from overlapping symptoms.

    Conclusions:

    • Patients with symptoms suggestive of intermittent claudication require careful evaluation to exclude neurogenic causes, particularly lumbar spinal stenosis.
    • A high index of suspicion for neurogenic claudication is warranted.
    • Neurosurgical consultation may be necessary for accurate diagnosis and management.
