[Clinical and imaging features of adult anoxic-ischemic encephalopathy after cardiopulmonary resuscitation].

OBJECTIVE

To explore the clinical and imaging features of anoxic-ischemic encephalopathy (AIE) patients after cardiopulmonary resuscitation.

METHODS

A total of 28 qualified AIE patients during the last decade from Xiangya Hospital, Central South University were recruited and analyzed retrospectively.

RESULTS

The symptoms of status epilepticus, acute posthypoxic myoclonus, Lance-Adams syndrome, subarachnoid hemorrhage and cognitive deficits were observed. The abnormal findings of magnetic resonance imaging (MRI) or computed tomography (CT), involving neocortex, basal ganglia and para-ventricular white matter, were also recorded. During the early phase of disease, swollen cortex was present on MRI/CT. However, encephalatrophy appeared during the late phase. The more severe symptoms were observed, the more foci were present on MRI/CT.

CONCLUSION

The etiologies of AIE patients are heterogeneous after cardiopulmonary resuscitation. The clinical symptoms and imaging studies are of prognostic significance.
