Abstract

Objective: To present a rare cause of recurrent posterior embolic strokes originating from a partially thrombosed pseudoaneurysm of a shoulder artery after arthroscopy.

Materials and methods: The clinical history, complementary studies and follow-up were reviewed.

Results: The patient was successfully embolized and presented no new ischemic episodes at the 3-month follow-up visit.

Conclusions: Shoulder artery pseudoaneurysm should be considered as an unusual source of posterior embolic strokes.

Keywords: Aneurysm, False, Subclavian Artery; Embolic Stroke, Posterior Cerebral Artery, Embolization, Therapeutic.
