# A Case of Traumatic Hemothorax From an Isolated Thoracic Vertebral Fracture in an Elderly Patient on Combined Anticoagulant and Antiplatelet Therapy

## TL;DR

An elderly patient on blood-thinning medication developed a hemothorax from a minor thoracic fracture, highlighting the need to consider vertebral fractures as a bleeding source in similar cases.

## Contribution

Highlights vertebral fractures as a potential bleeding source in hemothorax cases with unclear origins in anticoagulated elderly patients.

## Key findings

- Hemothorax occurred from a transverse laceration of the 10th thoracic vertebra without dislocation or contrast extravasation.
- Anticoagulant and antiplatelet therapy likely prolonged bleeding from a minor fracture.
- CT scans may not always identify vertebral fractures as bleeding sources in hemothorax.

## Abstract

Traumatic hemothorax is typically easy to diagnose because of the distinct onset of trauma with significant complaints such as severe chest pains. However, in elderly patients, the clinical symptoms are less clear and the frequent use of antithrombotic therapy may prolong the bleeding from a minor fracture. We report a case of traumatic hemothorax from an isolated thoracic vertebral fracture in an elderly patient on anticoagulant and antiplatelet therapy. A 91-year-old male on anticoagulant and antiplatelet therapy was admitted to our hospital with a complaint of persistent hemoptysis after a fall. A computed tomography (CT) demonstrated a worsening right hemothorax and thoracic vertebral fracture without lung or diaphragm injury, rib fracture, or contrast medium extravasation. The patient was taken to the operating room for the exploratory thoracoscopy and evacuation of the hemothorax without a preoperative diagnosis of the bleeding source. The bleeding was from the transverse laceration of the 10th thoracic vertebra exposed to the pleural space. The minor bleeding from the cancellous bone was prolonged, possibly due to the use of anticoagulant and antiplatelet therapy, which was not identified as contrast medium extravasation on chest CT before surgery. In cases of hemothorax with an unclear bleeding source, a vertebral fracture could be considered a source of bleeding even without any signs of bone dislocation or contrast medium extravasation on a CT scan.
