Background:
Malignant cerebral infarction has 80% mortality rate that could be decreased by hemicraniectomy.
Material And Methods:
We retrospectively evaluated medical records of all 12 consecutive patients who underwent hemicraniectomy due to malignant cerebral infarction in Kuopio university hospital between 2003 and 2/2009.
Results:
Infarction affected left hemisphere in 4/12 patients and right hemisphere in 8/12 patients. 50% of the patients (6/12) survived. Operation delay was not associated with outcome. Systolic blood pressure in acute phase was significantly lower in survivors as compared to non-survivors (126 +/- 8 mmHg vs 154 +/- 12 mmHg, p < 0.001, respectively).
Conclusions:
Selected patients with malignant cerebral infarction benefit from hemicraniectomy.
