[Arterial dissection: Different entities for the same name]

Area of Science:

• Vascular Medicine
• Cardiovascular Pathology

Background:

• Spontaneous arterial dissection (SAD) is a rare condition with unknown prevalence, affecting diverse arterial territories.
• Pathophysiology involves bleeding into the arterial media, with varied etiologies specific to each affected artery.
• Patients often present with few traditional cardiovascular risk factors, highlighting the need for alternative diagnostic considerations.

Purpose of the Study:

• To summarize the understanding of spontaneous arterial dissection.
• To highlight key diagnostic considerations and treatment approaches for SAD.

Main Methods:

• Review of existing literature on spontaneous arterial dissection.
• Analysis of pathophysiology, causes, and clinical presentations across different arterial territories.

Main Results:

• SAD can affect the aorta and medium-sized arteries, including cerebrovascular, coronary, and renal arteries.
• Fibromuscular dysplasia is a significant underlying condition in patients with SAD.
• Prognosis can be serious, impacting both vital and functional outcomes.
• Treatment strategies are territory-specific, severity-dependent, and consider the underlying etiology, with conservative management often being first-line.

Conclusions:

• Spontaneous arterial dissection is a complex vascular disease requiring tailored diagnostic and therapeutic strategies.
• Identifying underlying conditions like fibromuscular dysplasia is crucial for effective management.
• Conservative treatment is frequently the initial approach for spontaneous arterial dissection.
