Spinal, Cerebral and Cerebellar Embolism after Injection of N-Butyl-2-Cyanoacrylate in Esophageal Variceal Bleeding

Abstract

We report a case of spinal, cerebral and cerebellar embolism that occurred following injection sclerotherapy with n-butyl-2-cyanoacrylate for variceal bleeding. The patient had been diagnosed with alcoholic liver cirrhosis and esophageal variceal bleeding. We performed injection sclerotherapy with n-butyl-2-cyanoacrylate. The patient complained of both leg motor weakness and left arm motor weakness after injection and was diagnosed with spinal, cerebral and cerebellar embolism following the n-butyl-2-cyanoacrylate injection. At the follow-up examination, the patient's neurologic symptoms had improved, but left leg motor weakness remained. To our knowledge, this is the first report of a case of multiple embolizations including the spine, cerebrum and cerebellum after n-butyl-2-cyanoacrylate injection for treatment of esophageal variceal bleeding.
