| description | Purpose This study was performed to evaluate the relationship between callosal microbleeds
and anoxic brain injury.
Materials and Methods Twenty-seven patients with anoxic brain injuries were analyzed and
retrospectively compared to the control group of patients without a history of anoxic brain injury
using Fisher’s exact test regarding comorbidities and cerebral microbleeds. The patient
group was subdivided according to the presence of callosal microbleeds. Fisher’s exact test
was used to compare the presence of typical MRI findings of anoxic brain injury, use of cardiopulmonary
resuscitation, and prognosis. The Mann-Whitney U test was used to compare the interval
between the occurrence of anoxic brain injury to MRI acquisition.
Results The prevalence of cerebral microbleeds in the patient group was 29.6%, which was significantly
higher than that in the control group at 3.7% (p = 0.012). All cerebral microbleeds in
the patient group were in the corpus callosum. Compared with the callosal microbleed-absent
group, the callosal microbleed-present group showed a tendency of good prognosis (6/8 vs.
11/19), fewer typical MRI findings of anoxic brain injury (2/8 vs. 10/19), and more cardiopulmonary
resuscitation (6/8 vs. 12/19), although these differences did not reach statistical significance
(p = 0.35, p = 0.19, and p = 0.45, respectively).
Conclusion Callosal microbleeds may be an adjunctive MRI marker for anoxic brain injury. |
