Surgical treatment of multiple mycotic aneurysms: in the ascending aorta, aortic arch, and descending aorta.

We report a clinical case of multiple mycotic aneurysms, in the ascending aorta, aortic arch, and descending aorta. The patient underwent surgery to replace the ascending aorta and aortic arch by means of a highly modified "elephant trunk" technique and with the aid of arterial cannulation from the right subclavian artery, which provided antegrade cerebral perfusion. Samples of purulent material taken from the aneurysmal wall yielded cultures positive for Staphylococcus aureus. The patient was treated with antibiotics for 6 weeks and then underwent a 2nd procedure for the aneurysmal resection of the descending thoracic aorta and the abdominal aorta, through a thoracic laparo-phrenicectomy. We comment on the clinical and surgical aspects of the case.
