Decompressive craniectomy for massive internal carotid artery infarction after pediatric penetrating neck trauma.

Abstract

Pediatric penetrating carotid arterial trauma is a rare unreported cause of malignant cerebral infarction. Despite increasing evidence of benefit of decompressive hemicraniectomy (DCH) in pediatric malignant stroke, indications and predictors of outcome remain controversial. We report a 4-year-old boy with penetrating zone II neck trauma with laceration of the right internal carotid artery who developed malignant cerebral infarction requiring DCH. Impressive neurological recovery and excellent functional outcome was observed with good psychomotor development and quality of life. To our knowledge, this is the first reported case of pediatric malignant ICA infarction due to penetrating arterial trauma with good neurologic outcome after DCH.
