Open Access: One-year Angiographic Results After pCONus Stent-Assisted Coiling of 40 Wide-Neck Middle Cerebral Artery Aneurysms

Endovascular coiling is the reference therapy to treat ruptured intracranial aneurysms.1,2 In the setting of unruptured aneurysms, the endovascular approach is also frequently used.3 Nevertheless, management of middle cerebral artery (MCA) aneurysms remains a matter of debate and many institutions still use surgical clipping as the first treatment for MCA aneurysms.4-7 In fact, coiling alone of MCA aneurysms may be difficult or impossible because of the often complex anatomic features. MCA aneurysms with wide neck can be managed by endovascular approach with the advent of new endovascular tools specifically designed for the intracranial circulation.8-11 A recent device, the pCONus (phenox GmbH, Bochum, Germany), has been specifically developed to improve the feasibility and the safety of treatment of these challenging aneurysms.12,13 We recently published the immediate clinical and anatomic postoperative results of 40 consecutive patients harboring 40 wide-neck MCA aneurysms treated with pCONus device.13

Our aim was to evaluate the 1-year angiographic results in 40 wide-neck MCA aneurysms treated with pCONus device.
