A new method was developed to maintain a bloodless microscopic operative field for superficial temporal artery-middle cerebral artery (MCA) anastomosis surgery. A silicone suction tube with multiple holes is placed circumferentially under the reflected dural flaps around the craniotomy. Blood and irrigated saline are continuously aspirated by the tube. Use of this method in nine patients significantly reduced the mean MCA trapping time (24.0 +/- 2.8 min) compared with nine patients treated using the conventional method (30.1 +/- 4.6 min). MCA trapping time is shortened because the surgery is not interrupted for manual suctioning of bloody cerebrospinal fluid.
一种新方法被开发出来，用于在颞浅动脉-大脑中动脉（MCA）吻合手术中维持无血的显微手术视野。一根多孔硅胶吸引管被环形放置在开颅术周围翻转的硬脑膜瓣下方。血液和冲洗用生理盐水通过该管持续吸出。与采用传统方法治疗的9例患者（30.1±4.6分钟）相比，该方法在9例患者中的应用显著缩短了平均MCA阻断时间（24.0±2.8分钟）。由于手术过程中无需中断进行血性脑脊液的手动抽吸，MCA阻断时间得以缩短。
