Giant ICA Bifurcation Aneurysm: Radial Artery Bypass

The advent of microneurovascular techniques began in the early 1960s when Woringer reported the first high-flow (HF) extracranial-intracranial (EC-IC) bypass procedure. Although Woringer's technique was not initially popularized because of its complexity and the associated high morbidity, his progress was a major evolution in the field of cerebral revascularization.

It was not until the early 1970s when further medical and surgical advancements renewed interest in this form of vascularization. In 1971, William Lougheed performed a common carotid artery (CCA) to intracranial internal carotid artery (ICH) bypass with an interposition saphenous vein graft. His success paved the way for other surgeons to refine its use for treatment of c...
