Clipping surgery for an anterior choroidal artery aneurysm (AChAN) is associated with a high risk of ischemic complications, because the anterior choroidal artery (AChA) supplies critical territories, such as the internal capsule. We retrospectively analyzed 40 patients (age range, 34–79 years; mean age, 55.3 years old), comprising 11 males and 29 females, with AChAN who were treated in our institution between 1998 and 2010. Clipping surgery was performed for 24 ruptured and 16 unruptured…

A case of anterior choroidal artery occlusion test under MEP monitoring for a recurrent internal carotid artery–anterior choroidal artery bifurcation aneurysm clipping

Although postoperative magnetic resonance imaging with diffusion-weighted images showed ischemic signs in left AchA territory after the operation, the patient remained asymptomatic and was discharged home with mRS 0.



Ischemic complications of surgery for anterior choroidal artery aneurysms.

Most postoperative strokes occur in a delayed fashion, offering a potential therapeutic window, and patients with aneurysms arising from the AChA itself have an extremely high risk for postoperative stroke.

Analysis of Clip-induced Ischemic Complication of Anterior Choroidal Artery Aneurysms.

It is easy to classify as "easy" surgery, but surgery for AChA aneurysms carries with it a significant risk of postoperative stroke, so don't always stick to clipping only, especially in non-I type of incidental smallAneurysm, which has high risk ofpost-clip ischemic complications.

Aneurysmal Remnants After Microsurgical Clipping: Classification and Results from a Prospective Angiographic Study (in a Consecutive Series of 305 Operated Intracranial Aneurysms)

The aim of this prospective study was to check the absence of an aneurysmal remnant on post-operative angiography, and if a remnant was found to quantify its size in order to consider additional cliping to avoid the risk of rebleeding.

Endoscope-assisted Microsurgery for Intracranial Aneurysms

OBJECTIVE We discuss the role of the endoscope in the microsurgical treatment of intracranial aneurysms, analyzing its benefits, risks, and disadvantages. METHODS This was a prospective study of 55

Prospective analysis of aneurysm treatment in a series of 103 consecutive patients when endovascular embolization is considered the first option.

Surgical clipping can offer better results than CE, even for more complex aneurysms of the anterior circulation, especially for those involving the middle cerebral artery cases.

Arterial occlusive lesions following wrapping and coating of unruptured aneurysms.

Seven patients (mean age 57 years) developed arterial occlusive lesions following both wrapping and coating during surgery for unruptured aneurysms, which suggest that the cyanoacrylate glue is more likely to be the cause of the lesions than the cotton fibers.

Regrowth of aneurysm sacs from residual neck following aneurysm clipping.

It is found that 1- to 2-mm residual necks seen in postoperative angiography have been thought to pose little risk, but a surprising number of cases have been presented in which this seemingly unimportant remnant of the neck dilated over a long period to become a dangerous aneurysm.

Anterior choroidal artery aneurysms: their anatomy and surgical significance.

The anatomic variations of the origin of the anterior choroidal artery are discussed, and the danger of sacrificing the artery in aneurysm surgery is stressed.

Intraoperative monitoring of blood flow insufficiency in the anterior choroidal artery during aneurysm surgery.

The findings of this study suggest that the monitoring method introduced here is safe and reliable for detecting intraoperative BFI in the AChA.

Endovascular therapy of intracranial aneurysms.

The use of endovascular techniques, mostly detachable balloons, for treatment of intracranial aneurysms has progressed since balloons were first used in neuroendovascular therapy [1]. Although the
