Abstract:
Objective:To retrospectively analyze and compare the clinical effects of rigid neuroendoscopic hematoma removal and drilling irrigation drainage in the treatment of chronic subdural hematomas with mixed density on head CT, and explore the appropriate surgical methods for chronic subdural hematomas with mixed density.Methods:A retrospective case-control study was conducted to analyze the clinical data of 80 patients with CSDH with mixed density CT findings admitted to the Department of Neurosurgery of Guizhou Medical University Affiliated Hospital from January 2021 to November 2023. There were 57 males and 23 females. According to the surgical method, patients were divided into endoscopic group ( n=36) and drilling group ( n=44). Patients in the endoscopic group underwent hard neuroendoscopic hematoma removal surgery, while patients in the drilling group underwent drilling flushing and drainage surgery. Compared the surgical time, drainage time, hematoma clearance rate, length of hospital stay, markwalder neurological function grading, and activities of daily living (ADL) score between two groups 30 days after surgery. Followed up for 3 months to record the recurrence situation.Measurement data with a normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for inter-group comparison. Measurement data with a non-normal distribution were expressed as M( Q1, Q3), and rank sum test was used for inter-group comparison. Chi-square test or Fisher′s exact test was used for inter-group comparison of count data. Rank sum test was used for inter-group comparison of ordinal data. Results:The operation time, postoperative drainage time, 24-hour hematoma clearance rate, midline deviation distance and hospital stay in the endoscopic group respectively were (77.50±8.15) min, 1.00(1.00, 2, 00) d, (95.00±2.66)%, 1.00(0.00, 2.00) mm, (9.47±2.52) d. The drilling group were (44.77±6.56) min, 3.00(2.25, 3.00) d, (87.86±3.43)%, 3.00(2.00, 3.00) mm, (11.84±3.28) d, the difference was statistically significant between the two groups ( P<0.05). Comparison of long-term efficacy in the endoscopic group, the hematoma clearance rate at 30 days after operation, the ADL score at 30 days after operation, and the number of recurrence cases at 3 months after operation respectively were 99.00(97.25, 100.00)%, (88.06±7.86) points, and 1 case. The drilling group were 93.50(91.25, 95.75)%, (83.29±9.58) points and 10 cases, with statistical difference between the two groups( P<0.05). 30 day postoperative Markwalder neurological functional grading, there were 27 cases grades 0, 9 cases of grade I, and 0 cases of grade II in endoscopic surgery. In the drilling group, there were 24 cases, 15 cases, and 5 cases, respectively. The difference between the two groups was statistically significant ( P<0.05). Conclusions:Compared with drilling and drainage irrigation surgery, neuroendoscopic treatment of mixed density chronic subdural hematoma takes a relatively long time, but the hematoma clearance rate is higher, the hospitalization time is shorter, the postoperative recovery is faster and the recurrence rate is lower. Neuroendoscopic therapy has unique advantages and may be more suitable for the treatment of mixed density CSDH.
