First Hospital of Jilin University, Department of Neurosurgery, Changchun, China DOI : 10.5137/1019-5149.JTN.9150-13.0 Remote intraparenchymal hemorrhage after clipping of a ruptured aneurysm is rare. The pathogenesis is variable, and the therapeutic strategies remain controversial, because the natural history is unclear. Here we report a woman with subarachnoid hemorrhage (SAH), who had an aneurysm of the anterior communicating artery identified by computed tomography angiography (CTA). A 51-year-old women, who was in a good preoperative condition without movement disorders before operation, went on to exhibit left hemiparesis after aneurysmal clipping as she recovered from anesthesia in the operating room. CT images performed immediately after surgery showed that two intraparenchymal hemorrhages were present contralateral to the site of the operation. After conservative treatment, the patient recovered, but still displayed a movement disorder in the left limb. SAH induced-vasospasm, defective vascular autoregulation, excessive drainage of the cerebrospinal fluid, a change in the intracranial pressure after craniotomy, and brain shift may contribute to the pathogenesis of remote hemorrhage after surgery.
