Background: giant thoracic aortic aneurysms and aortic arch dissections are accompanied by high mortality rates, cardiac and neurologic events and pulmonary complications. Aorta-tracheal fistula and tracheobronchial compression are formidable and well-known complications of aneurysms of the thoracic aorta. Twenty-two percent of aneurysms that size >6 cm are ruptured with 80% mortality rate.Case presentation: a 56-year-old man with severe multivascular coronary artery injury and giant aneurysm of ascending aorta and aortic arch, complicated by respiratory failure and recurrent community-acquired pneumonia. Preoperative chest CT showed giant partially-thrombosed ampullary false aneurysm of ascending aorta, aortic arch and initial part of the thoracic aorta, 80x100x65 mm in size. Patient successfully underwent simultaneous surgical intervention with artificial blood circulation, the total time of cardiopulmonary bypass was 190 minutes.Conclusions: tracheobronchial compression syndrome with the aortic arch aneurysms is one of the urgent conditions that needs emergency surgery. Urgent indications for surgery in such cases include both significant size of the aneurysm and high risk of rupture, as well as potential for developing critical respiratory failure and recurrent nonresolving pneumonias. Preoperative CT enables to find out the exact location and evaluate the degree of airway compression, which determines further intraoperative actions. We recommend to use bronchoscopy at all steps of treatment of such patients, from intubation in operating room to extubation in intensive care unit. Thus, aggressive surgical tactics along with careful pre-operative diagnostic are the key to success and the only chance for such patients. |
