Palmar pseudoaneurysm following carpal tunnel release.

Carpal tunnel release surgery is a common and relatively safe surgical procedure; however, rare complications such as pseudoaneurysms can occur. Treatment of palmar pseudoaneurysms typically includes endovascular embolization or open ligation. We present a case of open surgical excision and repair of a pseudoaneurysm of the superficial palmar arch following carpal tunnel release surgery. This case study demonstrates how common surgical procedures can yield serious complications, thus highlighting the importance of thorough evaluations in pre-and post-operative care.
