[Arterial spasms of the limbs]

Area of Science:

• Vascular Medicine
• Radiology

Background:

• Peripheral arterial spasm is a significant clinical concern with diverse etiologies.
• Understanding vasoconstrictive pathways and predisposing factors is crucial for diagnosis and management.

Purpose of the Study:

• To review the causes of peripheral arterial spasm.
• To highlight the role of arteriography in diagnosing arterial spasm and associated conditions.

Main Methods:

• Review of anatomical and physiological data on vasoconstriction.
• Analysis of vascular radiographic opacification following arteriography to identify spasm characteristics.

Main Results:

• Arteriography is a precise technique for identifying, localizing, and defining arterial spasm.
• The study identified causes of acute ischemia and chronic ischemia presenting with cutaneous signs.
• Arteriography can reveal complications and inform treatment adaptations.

Conclusions:

• Peripheral arterial spasm has multiple causes, including iatrogenic spasm from arteriography.
• While not always mandatory, arteriography provides valuable insights into arterial status and vasomotor mechanisms.
• Diagnostic imaging via arteriography can lead to tailored treatment strategies for peripheral arterial spasm.
