Overview

Traumatic pseudoaneurysms are relatively frequently mentioned in textbooks of pathology and forensic medicine but their incidence in pathological reports is seldom documented. Our described case presented a patient who suffered from chronic alcoholism and who was repeatedly hospitalised because of various injuries including epidural and subdural hematomas. We present a case of a 69-year-old man who was hospitalised after nonspecific blunt chest injury with chest pain and dysphagia. By computed tomography the traumatic pseudoaneurysm of the descendent thoracic aorta was diagnosed pressing the oesophageal wall which was solved by implantation of aortal stent graft (TEVAR – thoracic endovascular aortic/aneurysm repair). Since after the implantation there was no blood leak, no progression of the lesion, he was soon discharged from hospital. The patient was hospitalised again after two months for newly developed haemoptysis. On suspicion of bleeding from aortal arch a carotid-carotid bypass from right to left side was performed and then re-TEVAR was implanted proximally to the first one. The man died two days following the implantation after a massive bleeding from oesophagus due to aortoesophageal fistula. The presented case deals with the etiology of the development of pseudoaneurysms, histomorphological picture of pseudoaneurysm resembling not only an isolated thoracic aortitis but slightly also the Takayashu disease. We suppose that in this case the most probable cause of necrosis and perforation of aortal wall was a decubital necrosis caused by stent graft which led to the fatal aortoesophageal necrosis. Aortoesophageal fistula belongs to the most common lethal complications of the TEVAR.
