Brain Edema After Ischaemic Stroke

OBJECTIVES To determine the incidence of brain edema after ischaemic stroke and its impact on the outcome of patients in the acute phase of ischaemic stroke. PATIENTS AND METHODS We retrospectively analyzed 114 patients. Ischaemic stroke and brain edema are verified by computed tomography. The severity of stroke was determined by National Institutes of Health Stroke Scale. Laboratory findings were made during the first four days of hospitalization, and complications were verified by clinical examination and additional tests. RESULTS In 9 (7.9%) patients developed brain edema. Pneumonia was the most common complication (12.3%). Brain edema had a higher incidence in women, patients with hypertension and elevated serum creatinine values, and patients who are suffering from diabetes. There was no significant correlation between brain edema and survival in patients after acute ischaemic stroke. Patients with brain edema had a significantly higher degree of neurological deficit as at admission, and at discharge (p = 0.04, p = 0.004). CONCLUSION The cerebral edema is common after acute ischaemic stroke and no effect on survival in the acute phase. The existence of brain edema in acute ischaemic stroke significantly influence the degree of neurological deficit.
