Abstract: The application value of color Doppler ultrasound in microsurgery and perioperative monitoring of cerebral hemodynamics in hypertensive intracerebral hemorrhage (HICH) is analyzed in this study. 87 patients with HICH were divided into ultrasound-guided group and conventional operation group. The hemodynamic parameters of middle cerebral artery were monitored by transcranial color Doppler ultrasound. The clearance rate of hematoma, incidence of cerebral infarction, short-term and long-term effects were compared. The results showed that the clearance rate of hematoma of ultrasound-guided group was higher than that of conventional operation group on the 2 days postoperative (P<0.05), the incidence of cerebral infarction was lower than that of conventional operation group on the 7 days postoperative (P<0.05), and the short-term and long-term effects were better than those of conventional operation group (P<0.05). Compared with the conventional operation group, the Vs, Vd, Vm of ultrasound-guided group were increased, PI was decreased on the 7 days postoperative (P<0.05). Therefore, color Doppler ultrasound is an effective method to monitor the changes of cerebral hemodynamics in HICH. Real-time ultrasound guidance can accurate the location of intracranial hematoma, improve the clearance rate of hematoma, and improve the prognosis.
