Endovascular management of thoracic aortic aneurysms

Chronic Cough as a Presenting Symptom of a Giant Thoracic Aortic Aneurysm: A Case Report

Chronic cough has a broad differential, and thoracic aortic aneurysm (TAA) is a rare but potentially life-threatening etiology. We present a giant arch TAA in a non-dyspneic, Pacific Islander man with significant tobacco-use history who presented with chronic cough with no acute pulmonary process noted on imaging. Given the high mortality rates associated with thoracic aortic aneurysms, the purpose of this report is to highlight the importance of keeping TAA as a rare differential for chronic cough, particularly when caring for patients with elevated risk. Recognition of patients with thoracic aortic disease who have a class I indication for surgical intervention (meaning there is evidence or general agreement that surgery will be beneficial, useful, and effective) as well as prompt evaluation of their anatomical landmarks in the perioperative period is critical. Imaging and, in particular, computed tomography remain the optimal modalities to screen for thoracic aortic disease.

Hemoptysis as a first symptom of endoleak after thoracic endovascular aortic repair, which caused aortic rupture and required complex management

Thoracic endovascular aortic repair (TEVAR) has become the most common procedure in the treatment of thoracic aorta aneurysms. However, potential long-term complications of this technique could be life-threatening. Hemoptysis is a common symptom of lung tumor, especially cancer. On the other hand, hemoptysis can also be caused by bronchitis, tuberculosis, mycosis, and trauma. In this case report, we present a patient with hemoptysis and lung tumor suggesting lung cancer, which was a unique symptom of type IA endoleak after TEVAR and led to rupture of the thoracic aneurysm. It was decided to perform next an endovascular procedure due to the severe state of the patient. Next the thoracotomy was performed because drainage of the left pleural cavity was unsuccessful. In the last stage bronchoscopy was needed to remove the thrombus, which occluded the left main bronchi. Successful management has led to the patient's full recovery. Despite justified popularity of endovascular procedures in the treatment of thoracic aorta aneurysms, we should remember about potential long-term complications. Hemoptysis could be a unique symptom of the endoleak after TEVAR and treatment of such complications could be complex and demanding.
