Primary angioplasty has been introduced for the treatment of symptomatic cerebral vasospasm in patients with subarachnoid hemorrhage (SAH). The data regarding the therapeutic benefit of angioplasty in improving patient outcomes are limited, hence its utilization at hospitals remains controversial and currently is not reimbursed by Medicare or major insurance companies. ⋯ Our analysis suggests that the odds of a patient being discharged to home are better at hospitals performing angioplasty for cerebral vasospasm. Provision of angioplasty may be used as a surrogate marker of model of care in management of patients with SAH.

Acquired hemophilia A (AHA) is an uncommon coagulation disorder caused by the development of autoantibodies against coagulation factor VIII (FVIII). While intracranial hemorrhage is a known complication of AHA, intracranial hemorrhage as the presenting manifestation of AHA has only been described in three previous case reports. ⋯ The presentation of intracranial hemorrhage with an isolated prolonged aPTT is concerning for an acquired hemophilia with FVIII deficiency. Other causes of isolated prolonged aPTT such as a lupus anticoagulant must also be considered. Preoperative identification and work-up of the coagulation abnormality is essential to guide initial treatment.

To date, common therapy in patients with intracranial hemorrhage (ICH) includes prophylaxis of seizure using antiepileptic drugs, commonly phenytoin. Phenytoin therapy is associated with a high incidence of cognitive disturbance. Levetiracetam is known to cause less cognitive disruption and may be a suitable alternative for seizure prophylaxis. Cognitive outcomes in ICH patients receiving seizure prophylaxis with levetiracetam or phenytoin are compared. ⋯ Despite similarities in hemorrhage type and severity at onset, patients receiving levetiracetam had better cognition at discharge and fewer seizures than patients receiving phenytoin. These data suggest that levetiracetam is more effective than phenytoin for seizure prophylaxis without suppression of cognitive abilities in patients with ICH.

We describe institutional vasopressor usage, and examine the effect of vasopressors on hemodynamics: heart rate (HR), mean arterial blood pressure (MAP), intracranial pressure (ICP), cerebral perfusion pressure (CPP), brain tissue oxygenation (PbtO(2)), and jugular venous oximetry (SjVO(2)) in adults with severe traumatic brain injury (TBI). ⋯ Most severe TBI patients received phenylephrine. Patients who received phenylephrine had higher MAP and CPP than patients who received dopamine and norepinephrine, respectively.

Percutaneous transluminal angioplasty (PTA) has been introduced for treatment of symptomatic cerebral vasospasm in patients with subarachnoid hemorrhage (SAH). While angiographic improvement is consistently reported, clinical improvement following the procedure varies, and limited data is available regarding overall impact on outcome. ⋯ A non significant trend was noted with reduced rate of severe disability and mortality at discharge and 1-year mortality after the introduction of PTA for cerebral vasospasm associated with SAH without increasing the length of hospital stay.
