Summary
A ruptured intercostal artery pseudoaneurysm, a rare complication of blunt thoracic trauma, can cause delayed, life-threatening hemorrhage. Surgical intervention may be necessary when endovascular embolization fails.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Interventional Radiology
Background:
- Blunt thoracic trauma can lead to delayed complications.
- Intercostal artery pseudoaneurysms are rare but potentially fatal vascular injuries.
Observation:
- A case of a ruptured intercostal artery pseudoaneurysm presenting two months after blunt thoracic trauma is described.
- The aneurysm hemorrhaged into the retroperitoneal space due to intrathoracic adhesions.
Findings:
- Endovascular embolization of the pseudoaneurysm was unsuccessful.
- Aneurysmectomy and hematoma removal were performed via a retroperitoneal approach.
Implications:
- Delayed hemorrhage from intercostal artery pseudoaneurysms following trauma requires prompt diagnosis and management.
- A multidisciplinary approach involving surgery and interventional radiology is crucial for successful outcomes.
