Abstract
Background
Ruptured middle cerebral artery aneurysm (MCAa) with intraparenchymal hematoma (IPH) can benefit at the same time from evacuation of the hematoma and exclusion of the aneurysm of a decompressive craniectomy (DC). To date, there are no clear recommendations for performing a DC in such cases.
Methods
We retrospectively collected data from nine French neurosurgical units from January 1, 2013 to December 31, 2020. All MCAa patients with IPH requiring evacuation of the IPH were included in this study. Poor outcomes were defined by an mRs score of 3–6 at 6 months. Propensity score matching was used to analyze the potential effects of DC.
Results
Between January 2013 and December 2020, 198 MCAa ruptured with IPH were treated, including 162 MCAa requiring evacuation of the IPH. 50 were treated with DC and 112 without DC. After matching 72 patients, poor neurological prognosis was observed in 27/36 patients (75%) in the DC group versus 18/36 (50%) in the non-DC group (p = 0.026).
Conclusion
Primary decompressive craniectomy in patients with ruptured MCAa and IPH requiring surgical evacuation increases the risk of poor neurological outcome. RCT are needed to confirm this hypothesis.
期刊介绍：
Neurochirurgie publishes articles on treatment, teaching and research, neurosurgery training and the professional aspects of our discipline, and also the history and progress of neurosurgery. It focuses on pathologies of the head, spine and central and peripheral nervous systems and their vascularization. All aspects of the specialty are dealt with: trauma, tumor, degenerative disease, infection, vascular pathology, and radiosurgery, and pediatrics. Transversal studies are also welcome: neuroanatomy, neurophysiology, neurology, neuropediatrics, psychiatry, neuropsychology, physical medicine and neurologic rehabilitation, neuro-anesthesia, neurologic intensive care, neuroradiology, functional exploration, neuropathology, neuro-ophthalmology, otoneurology, maxillofacial surgery, neuro-endocrinology and spine surgery. Technical and methodological aspects are also taken onboard: diagnostic and therapeutic techniques, methods for assessing results, epidemiology, surgical, interventional and radiological techniques, simulations and pathophysiological hypotheses, and educational tools. The editorial board may refuse submissions that fail to meet the journal''s aims and scope; such studies will not be peer-reviewed, and the editor in chief will promptly inform the corresponding author, so as not to delay submission to a more suitable journal.
With a view to attracting an international audience of both readers and writers, Neurochirurgie especially welcomes articles in English, and gives priority to original studies. Other kinds of article - reviews, case reports, technical notes and meta-analyses - are equally published.
Every year, a special edition is dedicated to the topic selected by the French Society of Neurosurgery for its annual report.
