[Intermittent claudication of the buttock (author's transl)]

Area of Science:

• Vascular Surgery
• Arterial Disease
• Clinical Diagnosis

Background:

• Buttock claudication of arterial origin is frequently overlooked.
• This condition stems from iliac artery pathologies.
• It coexists with patent femoral and popliteal arteries.

Purpose of the Study:

• To highlight the diagnostic importance of buttock claudication.
• To describe the arterial lesions causing this syndrome.
• To assess the risk of acute ischemia associated with iliac artery stenosis.

Main Methods:

• Clinical history review
• Physical examination findings
• Arterial lesion characterization (occlusion vs. stenosis)

Main Results:

• The syndrome is characterized by iliac artery lesions.
• Complete common iliac artery occlusion occurs in approximately one-third of cases.
• Pre-occlusive stenosis in the iliac arteries is present in two-thirds, posing a high risk for acute limb ischemia.

Conclusions:

• Buttock claudication is a significant clinical sign of iliac artery disease.
• Early diagnosis and management are crucial to prevent acute limb ischemia.
• Understanding lesion type (occlusion vs. stenosis) informs risk stratification.
