Predictors of surgical results in patients with primary pontine hemorrhage

Prediction of outcome for surgical patients with primary pontine hemorrhage (PPH) is seldom reported although many predictors from clinical and radiological features have been identified in conservative patients. The purpose of this study was to assess the prognostic factors affecting the 30-day mortality and 3-month functional outcome in surgical patients after PPH.Forty-five patients with large PPH ( > 5 ml) and Glasgow Coma Scale (GCS) score < 8 were treated surgically at West China Hospital. The demographic, clinical, imaging and follow-up data were collected retrospectively. Factors affecting the mortality and functional outcome were statistically analyzed.Fourteen patients (31.1%) died within 30 days and 7 patients (15.6%) gained a favorable functional recovery within 3 months. A multivariate analysis showed that the hematoma volume, GCS score on admission, age, and type of hemorrhage were all significantly related to the 30-day mortality, while the hematoma volume, GCS score on admission, rostrocaudal extension were associated with the 3-month functional outcome. The presence of hydrocephalus was not found responsible for the surgical outcomes.The identification of these prognostic factors is helpful for selecting the candidates for surgical treatment. Those with younger age, smaller hematoma without rostrocaudal extension, unilateral hemorrhage, and higher GCS score may benefit from surgery.
