transradial neurointerventional approach to basilar tip aneurysm: case report and technical note

Cerebral angiography through transfemoral approach is preferred in most of the situation though in cardiovascular surgery transradial angiography is accounted as the superior standard. the present study aimed at presenting our early experience of transradial approach to cerebral angiography and intervention of a patient with basilar tip aneurysm that had inappropriate vasculature to perform routine transfemoral approach. the patient was a 65 year-old man with a large basilar tip aneurysm that was candidate for endosacular coiling through transfemoral route. but due to very tortuous iliac artery, aortic arch and its branches, navigation transfemorraly via both vertebral arteries was impossible. therefore we decided to do the procedure through right transarterial route. the procedure was started by doing allen`s test to confirm good perfusion of right hand by collateral arteries. after that cerebral angiography and neurointervention was done transradially without any complication. as a result, although a transradial approach is not a routine way for cerebral angiography and intervention, it can be used safely as an alternative way in specific cases.
