Abstract


OBJECTIVE
The use of decompressive craniectomy for treating massive cerebral infarction is attracting much attention because conventional medical treatment is associated with high mortality. The aim of this retrospective study was to evaluate the surgical treatment results and prognostic factors for patients suffering with malignant cerebral infarction.
METHODS
We analyzed 9 consecutive patients who underwent decompressive craniectomy with or without temporal lobectomy after malignant cerebral infarction from 2000 to 2008. We reviewed the medical records, the radiological finding and the pre-operative clinical assessment using the Glasgow Coma scale (GCS). The postoperative functional outcome was assessed as the Barthel-Index (BI) and the modified Rankin scale (mRS).
RESULTS
The male to female ratio was 3.5:1. The mean age was 50 years (range: 36-68). Eight patients (89%) showed involvement of the entire middle cerebral artery (MCA) territory and the concomitant anterior cerebral artery (ACA) or posterior cerebral artery (PCA) territory. The preoperative mean GCS was 8.3 (range: 5-12) and the mean time to surgery after the onset of symptoms was 47.7 hours (range: 4-168 hours). All the patients underwent decompressive craniectomy and duroplasty. Among them, four patients (45%) underwent temporal lobectomy. The mean followup period was 7.3 months (range: 1-26 months) and five patients died within this period.
CONCLUSION
Decompressive craniectomy with or without lobectomy for patients with malignant cerebral infarction decreases the mortality rate and it improves the functional outcome. In the survived group, comparison of the two surgical modalities didn't show any statistically significant difference. However, the decompressive craniectomy with lobectomy group demonstrated a high survival rate (75%). Future studies are needed to investigate the proper treatment modalities for malignant cerebral infarction.
