What is the outcome following decompressive craniectomy for malignant middle cerebral artery infarction in patients older than 70 years old?
The outcome of decompressive craniectomy for malignant middle cerebral artery infarction in patients older than 70 years old is generally positive. Studies have found that decompressive craniectomy improves neurological outcomes in patients with extensive middle cerebral artery infarction. For example, the DESTINY II Investigators reported that hemicraniectomy in older patients improved survival and functional outcomes at 3 months. Additionally, a randomized controlled trial of decompressive hemicraniectomy in malignant middle cerebral artery infarct found that the procedure improved patient outcomes up to 80 years old. Other studies have also reported positive outcomes for decompressive craniectomy for other types of cerebrovascular diseases, such as acute cerebellar infarction and massive cerebellar infarction. However, it should be noted that the decision to perform decompressive craniectomy should be made on a case-by-case basis, taking into account the patient's medical history, the severity of the stroke, and other factors.
