Object: The authors present their experience in performing a transradial approach for neuroendovascular surgery of intracranial vascular lesions when a transfemoral approach was unfavorable.
Methods: Eight patients ranging in age from 52 to 88 years underwent a total of nine neuroendovascular procedures for intracranial vascular lesions. A transradial approach was used in all patients. The patients had previously undergone a transfemoral approach for the endovascular intervention, but that procedure was unsuccessful. Five patients had intracranial basilar artery (BA) aneurysms, one patient had symptomatic BA stenosis, one patient had a dural arteriovenous fistula in the posterior fossa, and one patient had a high-flow arteriovenous malformation in the frontal lobe. In each case, a transradial approach achieved a stable platform that allowed intracranial microcatheterization for neuroendovascular intervention. None of the patients experienced complications attributed to the transradial artery approach.
Conclusions: During neuroendovascular surgery for the treatment of intracranial lesions, the transradial approach is a viable alternative if the transfemoral approach is unfavorable. This series represents the first known description of neuroendovascular surgery for intracranial lesions via a transradial approach.
