[Raynaud's phenomena, syndrome and disease. Definition]

Area of Science:

• Vascular Medicine
• Clinical Terminology
• Peripheral Circulation Disorders

Context:

• The terminology surrounding acro-ischaemic conditions of the upper limb, particularly Raynaud's, is inconsistent.
• Lack of standardized definitions hinders clear communication among angiologists and affects patient diagnosis.

Purpose:

• To propose and advocate for strict, universally accepted definitions of Raynaud's phenomenon, syndrome, and disease.
• To clarify the distinctions between these related circulatory conditions.

Summary:

• Raynaud's phenomenon is defined as a transient circulatory crisis affecting the fingers, with full recovery.
• Raynaud's syndrome is diagnosed when the phenomenon is linked to an identifiable organic cause.
• Raynaud's disease is considered when the phenomenon occurs without any detectable underlying organic lesion.

Impact:

• Establishing clear definitions will improve diagnostic accuracy and consistency in vascular medicine.
• Standardized terminology will enhance communication among healthcare professionals and aid in patient understanding.
• This work aims to resolve ambiguity in the classification of upper limb ischaemic states.
