Closure intracranial pressure as a determinant of surgical decompression adequacy in spontaneous supratentorial intracerebral haematoma: a multicentre observational study.

PURPOSE: Despite significant advances, the literature on the optimal surgical treatment for spontaneous supratentorial intracerebral haematoma (ICH) remains lacking. Intraoperative ICP measured on closure (closure ICP) was reported to be a potential marker of adequate decompression in various neurosurgical conditions. We hypothesize that closure ICP also correlates with outcomes in ICH. METHODS: A multicentre retrospective study of 203 decompressive surgeries performed for ICHs was conducted (clot evacuation with either craniectomy or craniotomy). Receiver operating characteristic analysis on closure ICP was performed and an optimal threshold of 5 separated the patients into inadequate (iICP; ICP > 5 mmHg) and good decompression (gICP; ICP ≤ 5 mmHg). Postoperative ICP control, modified Rankin scale (mRS) and mortality were reported. RESULTS: There were 85 patients in the iICP and 118 patients in the gICP group respectively. The mean age, median preoperative Glasgow coma scale, ICH laterality, location, and volume were similar. After multivariable analysis, the need for (OR 2.55 [1.31-4.97]) and the duration of postoperative hyperosmolar therapy (iICP: 3 days, gICP: 1 day; p = 0.045), and repeat surgery for refractory ICP (OR 5.80 [1.53-22]) were more likely in the iICP group. The likelihood of mRS improvement at 1-year follow up was significantly worse in the iICP group (OR 0.38 [0.17-0.83], p = 0.015). CONCLUSION: Closure ICP is an objective and reproducible surgical target. When planning for surgical decompression, obtaining closure ICP of ≤ 5 mmHg is potentially able to improve postoperative ICP management and optimise functional recovery in a well selected patient population.

Management and Outcomes of Pediatric Craniopharyngioma: A 15-Year Experience in Singapore.

BACKGROUND: Craniopharyngiomas arise from the Rathke pouch and account for 1.2%-18.4% of pediatric primary brain tumors. Despite relatively good survival outcomes, patients face long-term morbidity from recurrences, visual impairment, and endocrinopathies, which reduce quality of life. We examined the management of pediatric craniopharyngiomas, their recurrences, and subsequent neuroendocrine sequelae in a tertiary center in South-East Asia. METHODS: A retrospective cohort of 12 paediatric patients (aged ≤18 years) with histologically confirmed diagnosis of craniopharyngioma treated from January 2002 to June 2017 was conducted. Data collected included demographics, clinical presentation, imaging data, treatment details, postoperative sequelae, and outcomes on mortality and recurrence. Survival analysis was conducted using Cox-proportional hazards model. RESULTS: The median follow-up time was 6.60 years (1.9-11.5 years). The mean age was 7.6 years (standard deviation 4.8) and 7 patients (58.3%) were male. The most common presenting symptoms were raised intracranial pressure (7, 58.3%), visual deficits (6, 50.0%), and preoperative endocrine abnormalities (2, 16.7%). Five patients underwent gross total resection (41.7%), and 7 underwent subtotal resection (58.3%). Overall survival was 75.0% (9 patients), and recurrence was 58.0% (7 patients). Median time-to-recurrence was 5.87 months (0.23-33.7, interquartile range 15.8), and median progression-free survival was 4.16 years (0.18-10.1, interquartile range 5.29). CONCLUSIONS: Long-term management of pediatric craniopharyngioma remains difficult, with multiple recurrences and long-term neuroendocrine sequelae impairing quality of life for patients. Further research into management of recurrences and neuroendocrine sequelae, as well as novel therapies to improve outcomes in these patients, may be warranted.
