Objective:
describe and evaluate the subclavian perfusion technique for selective cerebral protection with moderate hypothermia.Methods:
descriptive study of 19 patients to whom correction of the dissection or aneurysm of the aortic arch through the utilization of this technique was practiced.Results:
between September 2002 and September 2005, 19 patients were operated. 68.4% were men with mean age 54.05 ± 13.53 years. 57.8% corresponded to aortic dissection type A; the remaining 42.2% had aneurysms in some portion of the aorta, with arch involvement. 73.7% had aortic valve insufficiency. 47.3% were in functional class I, 31.5% in class II and 21% in class III. 36.8% required coronary revascularization. Mean time of selective cerebral perfusion was 28.95 ± 8.73 minutes; systemic perfusion was 163.31 ± 32.15 minutes; aortic clamping was 135.36 ± 34.48 minutes and mean temperature was 27.66° ± 0.94°C. There were 3 deaths. No definitive neurological complications were found.Conclusions:
this technique may be standardized for elective or emergent surgeries. It is a simple reproducible technique that allows more prolonged periods of time for the reconstruction of the aortic arch without producing cerebral ischemia; the extracorporeal circulation times are shorter, there are few bleeding complications, there is a decrease of cerebral anterograde embolism, and an excellent neurological result.
