Intrathoracic Aneurysm of the Right Subclavian Artery Presenting with Hoarseness: A Case Report

Intrathoracic segment of the subclavian artery is an unusual location for peripheral arterial aneurysms. They are normally caused by atherosclerosis, medial degeneration, trauma, and infection. We report a case of a patient with right subclavian artery aneurysm presenting with hoarseness. Chest radiograph demonstrated a superior mediastinal mass. Laryngoscopy showed a fixed right vocal cord. By chest computed tomography, magnetic resonance imaging, and angiography, preoperative diagnosis was established as a saccular aneurysm with afferent loop and efferent loop. Patient underwent complete resection of the aneurysm followed by endto-end anastomosis via median sternotomy. Postoperative pathology was consistent with an atherosclerotic aneurysm filled with thrombus. After surgical operation, hoarseness is still continued.

A Case of Cerebral Infarction in Young Woman with Graves' Disease and Atrial Fibrillation / 대한내분비학회지

Thyrotoxicosis associated atrial fibrillation occurs in 9 to 22% of hyperthyroidism patients; its prevalence increases after the age 60 years. Atrial fibrillation is known to be major independent risk factor for a thromboembolic stroke. The characterization of patient subgroups with atrial fibrillation, with high or low rate risk factor of a stroke, would help clinicians decide the benefit or harm to patient of long term anticoagulation therapy. Thyrotoxicosis, old age, hypertension, diabetes, heart failure, history of stroke and thromboembolism are all high risk factors for a stroke in atrial fibrillation patients. Thus, anticoagulation therapy is recommended for stroke prevention in those groups with atrial fibrillation and thyrotoxicosis. Herein is reported a case of acute cerebral infarction, with thyrotoxic atrial fibrillation and congestive heart failure, in a young woman
