Down-The-Barrel Working Projection for Coiling Selected Bifurcation Aneurysms in A Single-Plane Angiosuite.

Conventionally, the working projection for aneurysm coiling demonstrates the inflow artery, the aneurysm dome, the neck, and bifurcation branches in a two-dimensional (2D) image. We report two cases of ruptured Anterior communicating artery aneurysms, in whom a conventional working projection could not be obtained in a single plane angiography system. We used a down-the-barrel working projection created by aligning the origins of the A2 segments of bilateral anterior cerebral arteries to complete the coiling procedure.

Cone Beam CT to Guide Transorbital Treatment of a Cavernous Sinus Dural Arteriovenous Fistula in a Patient with Middle Meningeal Artery Origin of the Ophthalmic Artery.

Transorbital puncture to embolize cavernous sinus (CS) dural arteriovenous fistulas (DAVF) is a useful strategy when conventional transvenous routes are inaccessible. We report a case of bilateral CS DAVF associated with bilateral middle meningeal artery (MMA) origin of ophthalmic arteries (OA) who had recently undergone transvenous coil embolization. She presented with persistent symptoms of conjunctival congestion and proptosis in the left eye.

Balloon-Assisted Coiling of Intracranial Aneurysms: Technical Details and Evaluation of Local Complications.

Background: Wide-neck intracranial aneurysms need additional devices like balloons or stent for management. Balloon-assisted coiling has evolved both with interventionalist experience and device modifications.

Objective: We discussed our experience, evolution, and complications with this novel technique.

Balloon-Assistance for the Transcirculation Access of a Remodeling Balloon for Coiling of Wide-Necked Aneurysms: Report of Two Cases.

Balloons are valuable tools in the armamentarium of a neurointerventionist. In this report, we describe 2 cases in which a balloon aided in the navigation of a second remodeling balloon through difficult vascular anatomy. The first case was a patient with a ruptured proximal posterior inferior cerebellar artery aneurysm and the second case was a patient with a ruptured anterior communicating artery aneurysm.

Getting More Out of Follow-up Three-Dimensional Time-of-Flight Magnetic Resonance Angiography in Endovascularly Treated Intracranial Aneurysms.

Background: We retrospectively re-evaluated follow-up three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) in patients with aneurysms treated with coiling at our Institute.

Aims: To document the type and frequency of postcoiling residue patterns as seen on follow-up MRA and to document their evolution with time where a further follow-up MRA was available. To assess the implications of the location of the aneurysm on residue and recurrence.
