Dilating Vascular Diseases: Pathophysiology and Clinical Aspects

Area of Science:

• Vascular Medicine
• Cardiovascular Pathology

Background:

• Atherosclerotic disease significantly impacts global mortality and morbidity.
• Vessel dilation, encompassing venous (varicocele, varicose veins, hemorrhoids) and arterial (aneurysms) conditions, represents a distinct vascular pathology.
• These dilating vascular diseases are often misclassified as variants of atherosclerosis despite distinct characteristics.

Purpose of the Study:

• To differentiate dilating vascular diseases from atherosclerosis.
• To highlight the pathophysiological and histological similarities between arterial and venous dilating diseases.
• To propose a systemic view of vessel wall disease.

Main Methods:

• Review of existing literature on atherosclerotic and dilating vascular diseases.
• Comparative analysis of pathogenesis, histology, and clinical presentation.
• Synthesis of evidence supporting a systemic vessel wall disease model.

Main Results:

• Dilating vascular diseases share pathophysiological and histological similarities with each other.
• Clinical coexistence of these arterial and venous diseases is frequently observed.
• Despite similarities, dilating vascular diseases are distinct from atherosclerosis.

Conclusions:

• Dilating vascular diseases should be considered a systemic vessel wall disease, not merely local afflictions.
• Patients with any dilating vascular disease require systematic evaluation for other related conditions.
• Recognizing these conditions as systemic enhances patient management and prognosis.
