S: There is continuing controversy about the benefits of decompressive craniectomy in massive cerebral edema following space occupying hemispheric cerebral infarction. The aims of this study are to determine the effectiveness and to confirm the life-saving nature of decompressive craniectomy with dural augmentation for massive cerebral infarction. PATIENTS AND METHODS: We present twelve patients with medically uncontrollable hemispheric cerebral infarction. All were treated with extensive craniectomy and duroplasty without resection of necrotic tissue. We evaluated various characteristics(size of hemispheric infarction, Glasgow Coma Scale, volume of low density and midline shift in CT) at three different periods(preoperative, immediate postoperative and 3-4weeks after operation) and evaluated effectiveness of hemicraniectomy for massive cerebral edema after large hemispheric infarction.
All patients have survived from surgery. Nine patients with nondominant hemispheric infarction showed significant functional recovery with minimal assistance, and remaining two patients with dominant hemispheric infarction and one patient with nondominant hemispheric infarction have functionally dependent. The volume of low density and midline shift in CT were significantly reduced after decompressive craniectomy.
Our results indicate that decompressive craniectomy with dural augmentation without resection of necrotic tissue for massive cerebral hemispheric infarction not only reduce the mortality and infarction size but also significantly improve the outcome, especially for nondominant hemispheric infarction.
Key Words: Malignant cerebral infarction; Decompressive craniectomy; Low density; Midline shift
