主动脉夹层发生率与高血压病密切相关。高血压病人一旦发生主动脉夹层，急性期应在不影响心、脑、肾等重要脏器灌注的情况下，尽可能迅速而有效地降低动脉血压，收缩压应控制在90~100mmHg（1 mmHg=0.133kPa）之间，心率在60~70次/min之间。标准降压治疗方案为血管扩张剂硝普钠或硝酸甘油与β受体阻滞剂的联合应用。腔内修复术术中积极监测血压变化并适度控制性低血压是麻醉及手术成功的保证。

Abstract    Incidence of aortic dissection is closely related to hypertension. Once it has arotic dissection, blood pressure should be reduced quickly and effectively as far as possible during acute phase, without affecting the perfusion of some vital organs, like the heart, brain, and kidney. The systolic pressure should be controlled between 90~100mmHg, while heart rate between 60~70 times/min. It has been generally accepted that the standard antihypertensive treatment is the combined application of vasodilators like sodium nitroprusside or nitroglycerin andβ-blockers. It is the key to surgical success that blood pressure monitoring and controlled hypotension during endovascular therapy.
