Therapeutic efficacy of a novel simple manual bone cone drilling hematoma drainage for hypertensive intracerebral hemorrhage

Abstract

Objective To explore the efficacy of a novel and simple manual bone cone drilling hematoma drainage for hypertensive intracerebral hemorrhage. Methods From January 2021 to December 2022, 103 patients with hypertensive intracerebral hemorrhage at The Affiliated Bozhou Hospital of Anhui Medical University were included. They were treated with traditional bone cone drilling hematoma drainage (traditional group, n = 51) and novel-type bone cone drilling hematoma drainage (novel-type group, n = 52). Based on pre- and post-surgery head CT results, the hematoma clearance rate and accuracy of catheter placement were calculated. National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of neurological deficits, and modified Rankin Scale (mRS) was used to evaluate the neurological functional prognosis. Results The hematoma clearance rate in the novel-type group [(45.54 ± 24.23)% vs. (35.08 ± 6.49)%; t = 3.008, P = 0.004] and the accuracy of catheter placement [90.38% (47/52) vs. 68.63% (35/51); χ2 = 7.509, P = 0.006] were significantly higher than those of the traditional group. The novel-type group and the traditional group showed statistically significant differences in hematoma volume (F = 9.157, P = 0.003) and mRS score (F = 4.412, P = 0.038). The postoperative hematoma volume (t = - 4.625, P = 0.000) and mRS score (t = - 2.712, P = 0.008) of the novel-type group were lower than those of the traditional group. Statistically significant differences were observed in hematoma volume (F = 280.635, P = 0.000), NIHSS score (F = 443.320, P = 0.000) and mRS score (F = 552.781, P = 0.000) before and after surgery in the 2 groups; the hematoma volume (t = 10.233, P = 0.000; t = 19.906, P = 0.000), NIHSS score (t = 14.576, P = 0.000; t = 15.286, P = 0.000) and mRS score (t = 20.201, P = 0.000; t = 13.511, P = 0.000) after operation were lower than those before operation in the 2 groups. Conclusions The novel and simple manual bone cone drilling hematoma drainage is a safe and effective treatment for hypertensive intracerebral hemorrhage.
