Abstract

OBJECT: It is reported that spontaneous subcortical intracerebral hemorrhage consists about 10 to 44% of spontaneous intracerebral hemorrhage. Recently, spontaneous subcortical intracerebral hemorrhage due to the complication of the systemic disease has been increasing, and the selection of management strategy according to the cause of hemorrhage closely affected the management outcome. This study was designed to analyze the cause of spontaneous subcortical intracerebral hemorrhage and the outcome in order to establish the appropriate management strategy. SUBJECT: One hundred and seventy-nine cases of spontaneous subcortical intracerebral hemorrhage managed at Yonsei University Hospital from January 1998 to December 2000 were included in this study. Patients who suffered from subcortical intracerebral hemorrhage due to the ruptured intracranial aneurysm were excluded. The patient's sex, age, mental state on admission, neurologic condition, past history, systemic disease related to hemorrhage, location of hemorrhage, the diagnosis of intracranial or systemic disease, treatment methods, and clinical outcome were analyzed. Consciousness on admission was evaluated and scored based on Glasgow Coma Eye Motor Scale (GCEMS), which was the sum of eye response score and motor response score of the Glasgow Coma Scale. Patients were categorized into 4 groups according to GCEMS: Group 1 (10 points), Group 2 (8, 9 points), Group 3 (5-7 points), and Group 4 (2-4 points). The clinical outcome of the patient was evaluated based on Glasgow outcome scale (GOS). Differences in diagnostic procedure were present depending on the condition of the patients, thus the final diagnostic procedure was used to diagnose the reason behind bleeding. When accurate diagnosis was difficult to perform, the reasons with the highest likelihood were chosen.
RESULTS
The patients corresponding to each group were as follow: 79 (44.1%) in Group 1, 35 (19.6%) in Group 2, 27 (15.1%) in Group 3, and 38 (21.2%) in Group 4. Fifty-five patients (30.7%) were hypertensive intracerebral hemorrhage, 45 patients (25.1%) had anticoagulant therapy and thrombocytopenia due to the systemic disease and bleeding diathesis after anticancer drug therapy, 23 patients (12.8%) had brain tumor including the metastatic tumor, 19 patients (10.6%) had arteriovenous malformation, 18 patients (10.1%) had postinfarct hemorrhages, 5 patients (2.8%) had infective endocarditis, 2 patients (1.1%) had cerebral vasculitis. Conservative treatment was done in 115 patients (64.2%), open craniotomy in 31 patients (17.3%), and catheter insertion in 33 patients (18.4%). Group 1 mainly had conservative treatment (58 patients, 73.4%), Group 2 and 3 had 12 patients (37.1%) and 16 patients (59.3%) each underwent open craniotomy respectively. In Group 4, conservative treatment was done for 24 patients (63.2%), and open craniotomy was done for only one patients among 14 patients treated surgically. Overall clinical outcome was: 77 patients (43.0%) in GOS 5, 21 (11.7%) in GOS 4, 14 (7.8%) in GOS 3, 11 (6.1%) in GOS 2, and 56 patients (31.3%) died. Poor neurological state (low GCEMS) on admission was closely related to mortality (Group 1, 7.6%; Group 2, 22.8%; Group 3, 45.0%; Group 4, 78.9%).
CONCLUSION
The major causes of spontaneous subcortical intracerebral hemorrhage were hypertension, metastatic brain tumor, vascular malformation, and the bleeding tendency due to the systemic disease, complication of the anticancer drug, anticoagulant, and thrombolytics therapy. Conservative treatment could be considered for the patients with GCEMS 10, removal of hematoma by open craniotomy or catheter insertion for the patients with GCEMS 5-9, and the catheter insertion or deferring the active treatment could be considered for the patients with GCEMS 2-4.
