Surgical Management of large Basal Ganglia Hemorrhage: A Bi-institutional Experience

Background and Aim: Numerous prognostic factors for spontaneous intracerebral hemorrhage have been advocated; however, only a few studies have specifically addressed basal ganglia bleed prognosis and management. Regarding basal ganglia bleeding, this study determines the predictors of functional outcomes and predictors of severe disability or death in surgically treated cases. Methods and Materials/Patients: This was a one-time follow-up study of 271 spontaneous basal ganglia bleed patients undergoing surgical intervention over 3 years. An electronic hospital database was used to collect data regarding clinical and radiological parameters and functional outcomes according to the glasgow outcome scale (GOS) three months after the hemorrhage. Results: We analyzed 271 cases, with a mean age of 50.8±13.57 years. At the end of 3 months, 53.87% of patients had favorable outcomes (GOS=4, 5), 9.59% had poor outcomes (GOS=2, 3) and mortality was 37.75% (GOS=1) at the end of 3 months. Independent predictors of poor outcome were age (odd ratio [OR]=1.81, 95% CI, 1.09%, 3.02%, GCS OR=6.93, 95% CI, 1.52%, 31.51%), hematoma volume more than 60 mL (OR=12.73, 95% CI, 3.29%, 49.23%, midline shift (OR=2.78, 95% CI, 1.64%, 4.73%), the left side of bleed (OR=1.81, 95% CI, 1.11%, 2.94%), intraventricular hemorrhage (OR=2.94, 95% CI, 1.72%, 5.02%) and intraventricular hemorrhage associated with hydrocephalus (OR=22.30, 95% CI, 6.35%, 78.27%). There was a significant association between these factors and poor outcomes (P<0.05). Conclusion: Almost half of the patients with large basal ganglia hemorrhage survivors were severely disabled or died within three months after the event. Basal ganglia hemorrhage was associated with severe disability or death among patients aged over 60 years with left-side bleeding, low GCS on admission, preoperative computed tomography scan showing midline shift of more than 5mm with the presence of intraventricular hemorrhage or associated hydrocephalus and a large hematoma volume.
