Conservative Management in a Young Woman Affected by Isolated Left Subclavian Artery Dissection

抄録

Subclavian Artery Dissection (SAD) is a rare condition, generally due to arterial catheterization, blunt trauma or connective tissue disease. Spontaneous or minimally traumatic cases have also been reported. Clinical manifestations are usually chest and/or back pain, pulse loss and paresthesia, whereas nausea, dizziness and vomiting are present in case of involvement of the vertebral artery. We report an unusual case of a young woman presenting isolated left SAD after traffic accident, minimally symptomatic, and treated with medical therapy alone. A conservative management and a closed follow-up appear to be a safe approach in patients affected by uncomplicated SAD without other comorbidities.
