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

## TL;DR

A rare case of a pseudoaneurysm following ganglion cyst surgery in a patient with a blood disorder is reported.

## Contribution

Highlights a rare complication in ganglion cyst excision involving a pseudoaneurysm in a patient with May-Hegglin anomaly.

## Key findings

- A first dorsal metacarpal artery pseudoaneurysm occurred after ganglion cyst excision.
- The patient had May-Hegglin anomaly, a rare hematologic condition.
- The case emphasizes the need for careful perioperative management in such patients.

## Abstract

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.
