Dorsal Ganglion Cyst Excision Complicated by First Dorsal Metacarpal Artery Pseudoaneurysm: A Case Report.

Ganglion cysts are the most common masses of the hand and wrist. With less invasive measures, these masses often recur, pointing to surgical excision as definitive treatment. Surgical excision of ganglion cysts is considered a safe surgery with a lower recurrence rate than other treatments. We present a rare case of a first dorsal metacarpal artery pseudoaneurysm after a dorsal wrist ganglion cyst excision in a patient with May-Hegglin anomaly. This report describes the presentation, surgical approach, and perioperative considerations in a patient with a hematologic condition.
