Abstract: Objective  To explore the clinical efficacy and prognostic factors of YL-1 type hard channel trepanation and drainage combined with stereotactic treatment for hypertensive intracerebral hemorrhage.Methods  A retrospective study was conducted on 110 patients with hypertensive intracerebral hemorrhage at the Cerebrovascular Disease Center of the First People’s Hospital of Suzhou from August 2019 to October 2022.The observation group(55 cases) received YL-1 type hard channel drilling and drainage combined with stereotactic treatment,while the control group(55 cases) received simple YL-1 type hard channel drilling and drainage.The perioperative indicators,neurological damage,and prognosis of the two groups of patients were compared;Using multiple Logistic regression analysis to identify the prognostic factors affecting patients.Results  The perioperative indicators,neurological damage,and prognosis of the observation group were better than those of the control group(P<0.05);The admission NIHSS score(OR=2.504,P<0.05),simple minimally invasive drilling and drainage(OR=1.881,P<0.05),disease duration>24 hours(OR=2.782,P<0.001),and ventricular rupture(OR=2.252,P<0.05) are risk factors for poor prognosis in patients.Conclusion  The prolongation of the patient’s disease course,ventricular rupture,and severe neurological damage are associated with poor prognosis.Combining stereotactic minimally invasive surgery has a positive significance for improving the prognosis of patients with cerebral hemorrhage.
