Superior Thyroid Artery Pseudoaneurysm as a Complication of Transesophageal Echocardiography
نویسندگان
چکیده
Pseudoaneurysm is a pulsating hematoma that results from a tangential injury to an arterial vessel wall and could represent a complication after trauma. In head and neck region pseudoaneurysm is rare but could have catastrophic consequences. For this reason it must be recognized to prevent such events as hemorrhage or acute occlusion of the airway. In literature a pseudoaneurysm arising from superior thyroid artery (STA) has been reported only in tree cases, in one case after ultrasonographically guided chemical parathyriodectomy, one after radiotherapy for hypopharyngeal cancer and the last after fine needle aspiration biopsy (FNAC)of thyroid nodule. We report a case of STA after transesophageal ecocardiography guided cardioversion.

Pseudoaneurysm is a rare condition in the region of the fibrous body between the mitral and aortic valve, the mitral-aortic intervalvular fibrosa (MAIVF), that has been reported as a sequela of endocarditis and surgical trauma. MAIVF rarely occurs on native aortic valve after infective endocarditis (IE). It is often fatal because of its rapid progress, high rates of rupture and recurrence, and ...

Three weeks after this operation, the patient was readmitted with severe chest pain, which was not understood at that moment. Evaluatio...

W ith medical advances, mortality and morbidity rates associated with myocardial infarction (MI) have declined dramatically (1). Nevertheless, cardiogenic shock is the most common cause of death after an acute MI, followed by left ventricular (LV) rupture (2). A pseudoaneurysm, albeit rare (3), is more likely to rupture than is a true aneurysm and thus is a post-MI complication that warrants ur...
متن کاملPseudoaneurysm of mitral-aortic intervalvular fibrosa.
Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (MAIVF) is one of the rare complications of infective endocarditis. Echocardiography plays an important role in the diagnosis of this condition. Transesophageal echocardiography (TEE) is generally superior to the transthoracic approach in the evaluation of the complications resulting from infective endocarditis. In this report, we discus...

UNLABELLED A 59 year-old previously healthy male was admitted to the hospital with fever reportedly several days in duration. His physical examination was unremarkable at first. Pneumonia was initially diagnosed, but acute pulmonary edema with a new grade III to and fro murmur developed 1 week later. Transesophageal echocardiography (TEE) disclosed a pseudoaneurysm of the mitral-aortic interval...
