Abstract

Abstract Introduction Spontaneous intracerebral hemorrhage (SICH) is one of the most devastating forms of stroke with a mortality of 30 to 40%. We aimed to evaluate the effect of craniotomy size and volume of decompression on surgical outcome, complications, mortality, and morbidity in patients with supratentorial capsuloganglionic bleeds who underwent a decompressive craniectomy (DC) at our institute. Materials and Methods It is a retrospective study done between January 2015 and December 2019. All patients with capsuloganglionic bleeds who had DC and hematoma evacuation were included in the study. Results A total of 55 patients underwent DC for SICH at our hospital during the study period. Mean anteroposterior (AP) diameter of the bone flap was 12.42 cm. The volume of decompression did not influence mortality and morbidity in our study but a larger AP diameter was associated with a higher incidence of hydrocephalus. A smaller craniectomy with an AP diameter of < 12 cm caused a lesser reduction in midline shift (MLS). Persistent postoperative MLS had a significant impact on mortality and its reduction was dependent on the size of craniectomy (p =–0.037) Conclusion DC with a recommended AP diameter of 12 to 13 cm achieves optimal results in terms of reduction in MLS. Larger DC volume carries a higher risk of hydrocephalus and requires close follow-up.
