Objective: To review the experience of various positions aortic replacement by four branch prosthesis vessel.
Methods: From August 2003 to May 2005, we finished aortic procedures with four branch prosthesis vessel for 142 patients, aged (44 +/- 12) (22-78) years, weighted (72 +/- 20) kg (49-130 kg). We performed ascending aorta and total aortic arch replacement for 85 cases during right axillary artery cannulation for cardiopulmonary bypass and selected antegrade cerebral perfusion. 38 patients underwent one-stage total thoracoabdominal aortic replacement during deep hypothermic bypass and subsection circulatory arrest. 8 patients underwent one-stage total or subtotal aortic replacement during deep hypothermic bypass and selected antegrade cerebral perfusion and subsection circulatory arrest. We performed totally aortic arch replacement without utilizing cardiopulmonary bypass and hypothermic for 11 cases.
Results: The mortality was 4.2%. Cerebral complications occurred in 16 (11.3%). 2 patients suffered from permanence spinal cord dysfunction. 4 patients suffered from temporary spinal cord dysfunction.
Conclusion: The four branch vessel prosthesis can be used on aortic surgery dexterously. The approach may shorten she time of aortic arrest and arterial construction.
