Lethal hemothorax following thoracic dislocated spinal fracture: the usefulness of arterial embolization

A 68-year-old male fell from a height of 3 m. He was conscious and alert, and complained of back pain, dyspnea, and paraplegia with hemodynamic instability. Initial axial and three-dimensional computed tomographic (CT) scans revealed a massive hemothorax on the right side and a dislocation (Th11) of the thoracic bamboo spine (Fig. 1a, b). We believed that the cause of the hemothorax was from the injured intercostals artery following the dislocation of the thoracic spine; therefore, angiography was performed immediately to isolate the source of bleeding. Angiographic findings revealed extravasation of the contrast medium from the intercostal artery (Th11; Fig. 1c). Selective arterial embolization (AE) was performed with gelatin sponge particles. After AE, the extravasated contrast medium disappeared, and his hemodynamic state stabilized. On the 16th day of hospitalization, the thoracic spine fracture was successfully repaired, and he was kept at the hospital to recuperate. Life-threatening hemothorax is uncommon following a thoracic vertebral fracture [1,2]. There are only a few reports on life-threatening hemothorax following a thoracic vertebral fracture; surgical management was adopted in these cases [1,2]. However, treatment for life-threatening hemorrhage following fractures of the spine has not yet been established. This is the first successful treatment report on life-threatening hemothorax following thoracic vertebral fracture. We thought that AE was a good choice of treatment for our patient. However, this method could not be useful if the angiographic finding showed the extravasation of the contrast medium from the great anterior radicular artery (artery of Adamkiewicz) because of spinal infarction. Therefore, the method of management should be changed immediately. Int J Emerg Med (2009) 2:177–178 DOI 10.1007/s12245-009-0113-z
