Aortic arch aneurysm. Tracheobronchial compression as a vital indication for emergency surgery: A case report.

INTRODUCTION: Giant thoracic aortic aneurysms and aortic arch dissections are accompanied by high mortality rates, cardiac and neurologic events and pulmonary complications. Tracheobronchial compression with aorta-tracheal fistula is a rare complication of the aorta aneurysms. Aortic arch replacement in such case presents several formidable challenges. PRESENTATION OF CASE: This is the case report of successful surgical treatment of giant aortic arch aneurysm, complicated by airway compression, aorta-tracheal fistula and recurrent community-acquired pneumonia. DISCUSSION: Urgent indications for the aortic arch aneurysms surgery include significant size and high risk of rupture. As well as a visceral compression are presented. Bronchoscopy can be used to successfully treatment at all stages from trachea intubation to extubation. CONCLUSION: Aggressive surgical approach with careful pre-operative diagnostic are the key to success and the only one chance for patients with aortic arch aneurysm, complicated by airway compression.

Aortic homograft implantation after Ozaki procedure: Case report.

INTRODUCTION AND IMPORTANCE: The infective endocarditis incidence data for patients undergoing aortic valve neocuspidization with glutaraldehyde-treated autologous pericardium (Ozaki procedure) are rare, and the optimal surgical treatment strategy remains unclear. CASE PRESENTATION: This is the first case report of surgical treatment of infective endocarditis of aortic valve with cryopreserved homograft in an athlete with previously performed Ozaki procedure. CLINICAL DISCUSSION: The choice of homograft was dictated by the young age of the patient; professional activity as an athlete; refusal of anticoagulants and the need for wide excision of compromised tissues to mitigate potential risk of spread of infection as well as its recurrence. CONCLUSION: The use of the aortic homograft allowed us to radically remove the infected tissues and achieve hemodynamic characteristics similar to the native valve. This is probably the first case report of use of homograft to treat aortic valve endocarditis following Ozaki procedure.
