Objective To observe the effects of microvascular Doppler ultrasound(MVD)assisted clipping on cerebral hemodynamics and nerve function in patients with intracranial aneu-rysm(ICA).Methods Seventy-eight patients with ICA in our hospital from February 2023 to March 2024 were selected and divided into MVD group(n=39)and conventional group(n=39)according to surgical methods.The conventional group was treated with craniotomy and the MVD group was treated with MVD assisted craniotomy.The surgical effect,National Institutes of Health Stroke Scale(NIHSS)score,Baethel index(BI),cerebral hemodynamic index(anterior cerebral artery blood flow rate,middle artery blood flow rate,cerebrospinal fluid pressure)and complications were compared between the two groups.Results The excellent and good rate of MVD group was 94.87％higher than that of conventional group 79.49％(P＜0.05).The NIHSS score and BI index of MVD group were lower and higher than those of conventional group 1 week after operation(P＜0.05).One week after surgery,the anterior cerebral artery blood flow veloci-ty,middle artery blood flow velocity and cerebrospinal fluid pressure in MVD group were lower than those in conventional group(P＜0.05).The complication rate of MVD group was 5.13％lower than that of conventional group 20.51％(P＜0.05).Conclusion MVD-assisted clipping in the treatment of ICA patients can improve the surgical effect,improve cerebral hemodynamics,and promote the recovery of nerve function,with high safety.
