We sought to determine whether therapeutic temperature modulation (TTM) to treat fever after intracerebral hemorrhage (ICH) is associated with improved hospital complications and discharge outcomes. ⋯ Therapeutic normothermia is associated with increased duration of sedation, mechanical ventilation, and NICU stay, but is not clearly associated with improved discharge outcome.

Endovascular cooling is currently used for hypothermia treatment and fever reduction therapy. At the same time, little is known about the risks associated to endovascular cooling in patients treated with an endovascular cooling catheter (ECC). ⋯ Our data show that the treatment with ECC increases the risk of TEE in SAH patients. Therefore, especially when considered for fever reduction, non-invasive devices for surface cooling should be the first choice.

Subdural fluid collections (hygromas and effusions) in adults are usually seen following head trauma or overdrainage of cerebrospinal fluid (CSF) after CSF diversion procedures. We report an unusual case of subdural fluid collection that developed spontaneously 5 days after an aneurysmal subarachnoid hemorrhage (SAH). This patient neither had permanent CSF diversion procedure nor history of significant head trauma during her clinical course. ⋯ Subdural fluid collections following SAH can occur as a result of head trauma, external hydrocephalus, or as a treatment complication of CSF shunting and craniotomies. It is critical to differentiate simple hygromas from external hydrocephalus since their response to CSF diversion is entirely different.

Seizures are a common complication after intracerebral hemorrhage (ICH) but there is a substantial lack of information on the long-term incidence in ICH survivors and whether post-ICH seizures affect functional long-term outcome. ⋯ Post-ICH seizures among long-term ICH survivors are common and may contribute to unfavorable functional outcome. Especially lobar ICH patients with a history of alcohol abuse are at risk to develop post-ICH seizures. Therefore, this subgroup may represent a target population for a prophylactic anticonvulsive treatment approach, preferably investigated in a prospective randomized trial.

Glutamate and oxidative stress play important roles after subarachnoid hemorrhage (SAH). The ability to modulate glutamate transporter 1 (GLT-1) and the antioxidative effect of rosiglitazone have been demonstrated. We investigated the neuroprotective effect of rosiglitazone after SAH. ⋯ Rosiglitazone reduced SAH mortality, neurological deficits, body weight loss, GFAP loss, and cerebral vasospasm by preventing the neurotoxicity induced by glutamate and oxidative stress.
