Alpha horizontal stent delivery for coil embolization of a broad-necked large basilar apex aneurysm: a case report.

Ohshima T, Nagakura M, Nishizawa T, Kato K - Nagoya J Med Sci (2015)

Bottom Line: Due to difficulty accessing the right posterior cerebral artery (PCA), we abandoned the Y-stent technique.The procedure outcome was excellent without any complications.Alpha horizontal stent delivery via an antegrade approach for coil embolization of broad-necked large BA apex aneurysms may provide an effective therapeutic alternative, if other techniques are not feasible.

ABSTRACT
Here we describe a novel technique for single stent horizontal reconstruction and coil embolization for a broad-necked large basilar artery (BA) apex aneurysm. A previously healthy 77-year-old woman presented with a broad-necked large BA apex aneurysm. Due to difficulty accessing the right posterior cerebral artery (PCA), we abandoned the Y-stent technique. Instead, we decided to navigate the stent through the BA to the left PCA making a loop of the stent delivery catheter inside the aneurysm in an "alpha" fashion. The procedure outcome was excellent without any complications. Alpha horizontal stent delivery via an antegrade approach for coil embolization of broad-necked large BA apex aneurysms may provide an effective therapeutic alternative, if other techniques are not feasible.

Mentions: A large BA apex aneurysm was found during magnetic resonance imaging (MRI) of a previously healthy 77-year-old woman. Diagnostic catheter angiography revealed a large, broad-necked, relatively shallow aneurysm with a maximum diameter of 15.7 mm. The right P1 was 1.1 mm in diameter and the left was 1.5 mm (Figure 1). Neither Pcom artery was observed despite Allcock’s tests to determine flow through posterior communicating arteries. The patient was informed in detail about the nature of the unruptured aneurysm, and available surgical and endovascular treatment options. She eventually decided to undergo coil embolization.
