Background:
Chronic subdural hematoma (CSDH) is one of the common clinical intracranial hemorrhagic disorders, accounting for 16%-20% of bilateral CSDH. At present, the surgical treatment of bilateral CSDH mainly includes drilling drainage and neuroendoscopic assistance. The main objective of this paper was to compare the effects of two surgical methods on CSDH.
Methods:
153 patients who were diagnosed with CSDH were included in this study. 79 patients were treated with bilateral drilling drainage, and the other 74 patients were treated with neuroendoscope-assisted drainage. The clinical data of the two groups were compared, and the surgical indexes, neurological function, cure rate, and recurrence rate of the two groups were compared. The operation indexes of patients include operation time, postoperative hematoma volume, hospital stay, extubation time, misplacement of drainage tube, recurrence, and hematoma clearance rate.
Results:
All patients underwent CT examination one day after operation. The CT imaging detection of the two groups was generally good. The cranial CT was reexamined before discharge. The bilateral hematoma disappeared in 114 patients, the unilateral hematoma disappeared in 29 patients, a small amount of compensatory crescent very low-density shadow subdural effusion was observed on the other side, and a small amount of compensatory crescent very low-density shadow subdural effusion was observed on both sides in 10 patients. There was no space occupying effect and intracranial gas disappeared. Compared with neuroendoscopic assisted drainage, the operation time of drilling drainage patients was significantly shorter. The extubation time, drainage tube dislocation, recurrence rate, postoperative hematoma volume, and hematoma clearance rate of patients receiving neuroendoscopic assisted drainage were significantly better than those receiving drilling drainage. The Markwalder score and hospital stay between the two groups were not significant.
Conclusions:
Drilling drainage and neuroendoscopic assisted surgery have good therapeutic effects on bilateral CSDH. The operation time of drilling drainage is shorter. Neuroendoscopic assisted surgery has more advantages in extubation time, misplacement of drainage tube, recurrence, postoperative hematoma volume, and hematoma clearance rate.
