title: A clinical characteristic analysis of pregnancy-associated intracranial haemorrhage in China.
abstract: Intracerebral haemorrhage (ICH) occurring during pregnancy and the puerperium is an infrequent but severe complication with a high mortality and poor prognosis. Until recently, previous studies have mainly focused on the effect of different treatments on prognosis. However, few studies have provided solid evidence to clarify the key predisposing factors affecting the prognosis of ICH. In the present study, based on a unique sample with a high ICH incidence and mortality rate, we described the main clinical characteristics of ICH patients and found that the prognosis of patients who underwent surgical intervention was not better than that of patients who received other treatment modalities. However, pre-eclampsia patients had higher maternal and neonatal mortality rates than other aetiology groups. Furthermore, univariate regression analysis identified onset to diagnosis time (O-D time) and pre-eclampsia as the only factors showing independent correlation with poor maternal outcomes (modified Rankin Scale, mRS ≥ 3), and only O-D time was identified as a predictor of maternal mortality. These results revealed that the aetiology of ICH and O-D time might be crucial predisposing factors to prognosis, especially for patients with pre-eclampsia. The study highlighted a novel direction to effectively improve the prognosis of pregnancy-associated ICH.
