Circumflex Scapular Artery Pseudoaneurysm as an Unusual Source of Emboli in Recurrent Posterior Circulation Stroke

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.
