Prospective assessment of aneurysmal rupture risk scores in patients with subarachnoid hemorrhage: a multicentric cohort.

Purpose: The natural evolution of unruptured intracranial aneurysms (UIA) is indeed difficult to predict at the individual level.

Objective: In a large prospective multicentric European cohort, we aimed to evaluate whether the PHASES, UCAS, and ELPASS scores in patients with aneurysmal subarachnoid hemorrhage would have predicted a high risk of aneurysmal rupture or growth.

Methods: Academic centers treating patients with intracranial aneurysms were invited to prospectively collect de-identified data from all patients admitted at their institution for a subarachnoid hemorrhage-related to intracranial aneurysmal rupture between January 1 and March 31, 2021 through a trainee-led research collaborative network.

[Neonatal intracranial hematoma in hemophilia A].

A case of subdural and intracerebral hematoma which appeared spontaneously in a neonate with severe hemophilia A is reported. This rare complication justifies some preventive measures in families at risk : antenatal ultrasonographic diagnosis of sex, vitamin K administration to the mother at the end of pregnancy and plasma assay for factors VIII and IX in the male neonate. Clinical and ultrasonographic examination of the intracranial content must be repeated during the first week of life and specific replacement therapy must be instituted if the clinical condition requires it.
