Accidental introduction of contrast medium into the cervical spinal cord. A case report.

abstract：PURPOSE:The purpose of this study is to investigate whether hemodynamics of unruptured, irregular small intracranial aneurysms (SIAs) are different from those of regular ones and large intracranial aneurysms (LIAs) in ophthalmic artery segment of internal carotid artery (ICA). METHODS:Between April 2015 and June 2018,...
