Abstract: Objective To explore the value of intraoperative ultrasound during microscopic surgery for hypertensive intracerebral hemorrhage. Methods This study included 22 patients with hypertensive intracerebral hemorrhage who underwent microscopic evacuation at our hospital from January 2023 to February 2024.These patients were divided into a non-ultrasound group (14 patients) and an ultrasound group (8 patients).Clinical data of all patients were collected.The primary outcomes were the residual hematoma rate on the CT scan the day after surgery and the Glasgow Outcome Scale (GOS) six months post-surgery;secondary outcomes included the duration of surgery and total hospital stay.The differences between the two groups were analyzed. Results There was no significant difference in age,gender,location of bleeding,amount of bleeding and Glasgow Coma Scale before surgery between the two groups.The median residual hematoma rate in the ultrasound group was significantly reduced to 10.00% (range 10.00,10.00) compared to 20% (range 13.75,20.00) in the non-ultrasound group (P=0.002).The total hospital stay was also reduced by 40% in the ultrasound group (33.38±6.32 vs.58.07±20.69 d,P=0.004).However,no significant difference in the six-month GOS score and surgery duration between the two groups was observed. Conclusion Intraoperative ultrasound is a convenient and effective monitoring method during microscopic hematoma evacuation,which can effectively reduce residual hematoma in patients with hypertensive intracerebral hemorrhage (hICH),shorten hospital stays,and promote postoperative recovery.
