摘      要：Background Rapid right ventricular pacing is one of the methods for counteracting the ＂wind sock＂ effect in the thoracic endovascular aortic repair （TEVAR）. Most of the doctors are to complete this operation under general anesthesia. Now, our operation has been performed under local anesthesia. No related reports were found as to whether can the patient tolerate rapid fight ventficular pacing under local anesthesia. Methods From 2009 January to 2010 January, in our hospital all the DeBakey llI aortic dissection patients who underwent TEVAR were randomly divided into general anesthesia group （n = 50） and local anesthesia group （n = 51）. All the data were compared between two groups including the hemodynamic indexes, the graft positioning accuracy, rapid pacing duration, operation time, intraoperative discomfort and postoperative neurological understanding function changes and the complications. Results The success rate were 100% in the two groups. The duration of rapid pacing, operation time, the accuracy of graft localization and the intraoperative discomfort scores of Numerical Pain Rating Scale showed no significant difference between the two groups （P 〉 0.05）. There were no rapid fight ventricular pacing-related complications in the two groups. Conclusion During thoracic endovascular aortic repair procedure, rapid fight ventricular pacing under local anesthesia is safe and feasible. Thus it is worthy to be popularized in clinical practice.
