RESUMO
Between 1996 to 2000, 12 patients with arteriosclerotic thoracic aortic aneurysm underwent surgery with cardiopulmonary bypass using the right axillary artery as an arterial inflow. All patients received total arch replacement with selective cerebral perfusion and deep hypothermic circulatory arrest. One patient with occlusion of the left carotid artery died of postoperative stroke. There were no postoperative complications or deaths related to axillary artery perfusion except for cerebrovascular accidents. Perfusion through the axillary artery, providing antegrade aortic flow, is a safe and effective procedure to avoid stroke owing to retrograde arterial perfusion. We believe that the axillary artery could be an alternative to conventional femoral artery cannulation in the setting of aortic arch operations.
RESUMO
A 55-year-old man was admitted with a thoracic aortic aneurysm causing wheezing. Computed tomography and angiography revealed a large distal aortic saccular aneurysm, occupying the retrotracheal space and compressing the trachea. There has been only one report of this type of aneurysm. This patient needed emergency intubation because of severe dyspnea caused by premedication for surgery. Replacement of the distal arch was performed via left posterolateral thoracotomy. Profound hypothermia was used during open proximal anastomosis, which helped to make this procedure safe and simple. This patient recovered uneventfully.
