Outcomes following decompressive craniectomy for aneurysmal subarachnoid hemorrhage

Takeaway

  • A larger craniectomy flap (> 105 cm2) was associated with better outcomes in patients treated with decompressive craniectomy (DC) for aneurysmal subarachnoid hemorrhage (SAH), including reduced risk of cerebral infarct, hospital death, and poor outcome at 6 months.

Why this matters

  • DC is an established technique for relieving intractable intracranial pressure (ICP) and can be used in patients with aneurysmal SAH.

  • Size of craniectomy flap is an important predictor of functional outcomes in patients with traumatic brain injury and ischemic stroke; however, the impact of craniectomy size is unknown in people with aneurysmal SAH.
