A 68-yr-old man with a 9-yr history of hypertension presented for hemiglossectomy, segmental resection of the mandible, and the radial forearm free flap grafting. Intraoperatively, facial artery spasm was observed during microvascular suturing of the radial artery to the facial artery. Simultaneously, systolic blood pressure decreased from 100 to 80 torr and the ST segment elevated to 15 mm from the base line. The possible mechanisms responsible for vasospasm in coronary as well as in peripheral arteries under sevoflurane anesthesia are discussed.
一名患有9年高血压病史的68岁男性接受了半舌切除术、下颌骨节段切除术和桡骨前臂游离皮瓣移植术。术中，在将桡动脉与面动脉进行微血管缝合时观察到面动脉痉挛。同时，收缩压从100 torr降至80 torr，ST段从基线抬高至15 mm。本文讨论了七氟醚麻醉下冠状动脉和外周动脉血管痉挛的可能机制。
