Perihematomal Edema and Functional Outcomes in Intracerebral Hemorrhage: Influence of Hematoma Volume and Location.
Perihematomal edema (PHE) is associated with poor outcomes after intracerebral hemorrhage (ICH). PHE evolves in the early period after ICH, providing a therapeutic target and window for intervention. We studied the effect of PHE volume expansion in the first 72 hours (iPHE) and its relationship with functional outcomes. ⋯ Absolute increase in PHE during 72 hours was associated with worse functional outcomes after ICH, particularly with basal ganglia ICH and hematomas <30 mL.

Cerebral arterial vasospasm (CVS) is a common complication of aneurysmal subarachnoid hemorrhage strongly associated with neurological deterioration and delayed cerebral ischemia (DCI). The utility of screening for CVS as a surrogate for early detection of DCI, especially in patients without clinical signs of DCI, remains uncertain. ⋯ Patients asymptomatic before screening have low rates of CVS and seem to be at negligible risk of developing DCI. Routine screening of asymptomatic patients seems to have little utility. Screening may still be considered in patients with possible symptoms of DCI or those with examinations too poor to clinically detect symptoms because finding CVS may be useful for risk stratification and guiding management.

Aneurysmal subarachnoid hemorrhage is a serious disease with high case fatality and morbidity. Delayed cerebral infarction (DCI) is an important surrogate marker. How location and infarct load affected outcomes was unclear. We aimed to assess the effects of load and location of DCI on outcomes of aneurysmal subarachnoid hemorrhage at 3 months. ⋯ Middle cerebral artery cortical and perforator zone infarct loads are potential surrogate marker to assess the severity of delayed cerebral ischemia.

The epidemiology of dialysis requiring acute kidney injury (AKI-D) in acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH) admissions is poorly understood with previous studies being from a single center or year. ⋯ Incidence of AKI-D complicating hospitalizations with cerebrovascular accident continues to grow and is associated with increased mortality and adverse discharge. This highlights the need for early diagnosis, better risk stratification, and preparedness for need for complex long-term care in this vulnerable population.

With the increased investigation of cerebral arteries using magnetic resonance angiography in the general population, the detection of unruptured intracranial aneurysms (UIAs) has increased. Understanding the distribution and factors associated with UIAs might be helpful for understanding the pathomechanism. ⋯ The risk factors for UIAs differ by their location, compared with the control. Interestingly, the presence of coronary artery disease was protective against the presence of UIAs.
