A revised stent-retriever anchor technique to obtain the distal access through a large or giant aneurysm

Abstract

Endovascular treatment of brain aneurysms with flow diverter device can be technically difficult. Obtaining distal access through the wide neck of a large or giant aneurysm may be challenging and sometimes the microcatheter needs to be looped inside the aneurysm. However, the inability to resolve this loop and to straighten the microcatheter can preclude flow diverter placement. This brief report presents four cases of large/giant aneurysms treated with flow diverter device, in which our innovative stent-retriever anchor technique was used to obtain the distal access of the parent artery. All procedures were technically successful, and no complications were recorded
