Comparison of craniotomy and decompressive craniectomy in large supratentorial intracerebral hemorrhage.

Intracerebral hemorrhage (ICH) is devastating disease with high mortality and morbidity rates. Most ICH is evacuated by either craniotomy (CR) or decompressive craniectomy (DC) although optimal treatment has not been established yet. The objective of this study was to compare clinical outcomes of spontaneous ICH patients between CR and DC groups and determine clinical factors affecting clinical prognosis. We retrospectively analyzed our single-center experience with large supratentorial ICH. From January 2011 to December 2016, 286 consecutive supratentorial large ICH patients underwent surgery in our institute. We compared CR group and DC group with regard to age, sex, GCS score, hematoma volume, midline shift, ICH score, and time from ictus to surgery. Statistical analysis was done using the t-test or x2 test, and odds ratio was calculated. During study period, CR was performed in 139 patients while DC was performed in 125 patients. There were no significant difference in 30-day mortality between the CR group and the DC group (13.7% vs 15.2%, p = 0.729). However, 12-month functional survival was 46.0% in the CR group, which was significantly (p = 0.014) higher than that (32.0%) of the DC group. In conclusion, the 30-day mortality of CR group was not inferior to that of the DC group while its 12-month functional survival was superior to that of the DC group. This suggests better functional outcome might be obtained for selected large ICH patients with CR than with DC.
