Microsurgical treatment assisted by intraoperative ultrasound localization: a controlled trial in patients with hypertensive basal ganglia hemorrhage.
This study investigated the clinical value of performing microsurgical treatment on hypertensive basal ganglia hemorrhage assisted by intraoperative ultrasound localization (IUL). A total of 107 patients with hypertensive basal ganglia hemorrhage were randomly separated into two groups for this controlled clinical trial. In the IUL group, 51 patients with hypertensive basal ganglia hemorrhage were operated on with the support of ultrasonic imaging; 56 patients underwent conventional microsurgery to evacuate the hemorrhage. The results of the two methods were evaluated according to the rate of hematoma evacuation, re-hemorrhage, mortality, complications, and activities of daily living (ADL). A greater quantity of the hemorrhage was removed from patients in the IUL group, with over 90% of masses being eliminated from the brain in 78.43% of these patients (40 out of 51 patients) compared with 60.71% of patients in the control group (34 out of 56 patients). The IUL group experienced a lower rate of re-hemorrhage after the operation (7.84%, 4 out of 51 patients) compared with the control group (17.86%, 10 out of 56 patients). A significant difference in the ADL score was recorded between the two groups, with ADL scores of the IUL group exceeding 60 (indicating good recovery) at 6 months after the operative procedure (P < 0.05). In conclusion, the microsurgical treatment of hypertensive basal ganglia hemorrhage assisted by IUL improved the precision of the operation. This procedure removed the hemorrhage and reduced the changes of re-occurrence, as well as elevated the quality of life of patients after the operation.
