RÉSUMÉ

Objective To evaluate the monitoring effect of microvascular Doppler blood flow detector in intracranial aneurysm surgery. Methods One hundred and twenty patients with intracranial aneurysms from July 2015 to July 2017 who received craniotomy and used microvascular Doppler ultrasound 1 mm microprobe to detect the hemodynamics of the parent artery and related perforating artery change were retrospectively analyzed . According to the blood flow signal, aneurysm clip was not adjusted in 55 cases; when the tumor artery or perforator artery blood flow signal decreased or disappeared after treatment, aneurysm clip clamping position was changed in 65 cases, so that the blood flow of tumor artery or perforator artery returned to normal. The blood flow velocity and pulsation index (PI) of the artery was measured before and after adjustment of the aneurysm clip. The patients underwent CT angiography (CTA) or DSA examination 1 week after surgery. Angiography was performed to evaluate the postoperative results in one month, three months, and six months' follow-up. The data obtained were statistically analyzed. Results Vascular obstruction or neck residual rate of 120 cases was lower than 5%vascular obstruction or residual neck residual rate in large cases. Conclusions The microvascular Doppler blood flow detector is safe, reliable and easy to operate. This technique is useful for finding the clips in the craniotomy of the intracranial aneurysm or the incomplete clamping of the tumor-bearing artery, so as to adjust the position of the aneurysm clip in time and improve the curative effect.
