Stent-assisted coiling and flow diverters effectively treat rare basilar artery cases

Basilar trunk artery aneurysms (BTAs) are among the rarest and most complex types of brain aneurysms, occurring in a critical vessel that supplies blood to the brainstem. Because of their location and low incidence, there has been limited research guiding how best to treat them, leaving neurosurgeons with few large datasets to inform clinical decisions.

Stent-assisted coiling and flow diverters effectively treat rare basilar artery cases. Basilar trunk artery aneurysms (BTAs) are among the rarest and most complex types of brain aneurysms, occurring in a critical vessel that supplies blood to the brainstem. Because of their location and low incidence, there has been limited research guiding how best to treat them, leaving neurosurgeons with few large datasets to inform clinical decisions. A new study led by Dr. Youxiang Li from Beijing Tiantan Hospital, Capital Medical University, and Dr. Wei Feng from the Department of Neurosurgery at Songyuan Jilin Oilfield Hospital, China, helps address this gap by providing one of the most comprehensive analyses of endovascular treatment (EVT) outcomes for BTAs in the modern "flow diverter" era. The research, published on March 5, 2026, in the Chinese...
