动脉瘤术后并发症的主要原因是瘤体前动脉或瘤体后分支动脉的阻塞。术中微血管多普勒超声可以适时评价血流,指导瘤体的钳夹部位。本研究旨在评价动脉瘤术中应用微血管多普勒超声判定血流动力学变化的效果和可靠性。 作者在对35例(22岁～80岁,平均55岁)动脉瘤病人实施手术治疗时,将一种新的、直径1mm～1.5mm、频率为20MHz的多普勒微血管探头,直接放置在血管的各段上,获取脑动脉血流频谱。探测角度45度
The main cause of postoperative complications of aneurysms is obstruction of the anterior arterial artery or branch arteries behind the tumor. Intraoperative microvascular Doppler ultrasound can timely evaluate the blood flow and guide the clamping site of the tumor. The purpose of this study was to evaluate the efficacy and reliability of microvascular Doppler ultrasound in judging hemodynamic changes during aneurysm surgery. The authors performed a surgical treatment of 35 patients (22 to 80 years old, average 55 years old) with aneurysms. A new Doppler microvascular probe with a diameter of 1 mm to 1.5 mm and a frequency of 20 MHz was placed directly on the blood vessels. On each segment, the cerebral artery blood flow spectrum was obtained. Detection angle of 45 degrees
