Anterior Communicating Artery Aneurysm

We present a case of a patient with an anterior communicating artery aneurysm treated by PulseRider-assisted coil embolization. PulseRider is a new device, FDA approved for treatment of broad-necked aneurysms of the basilar apex or internal carotid artery terminus. The aneurysm was broad-necked and involved the anterior communicating artery and was considered for traditional stent-assisted coiling as well as PulseRider-assisted coiling. The authors present the treatment plan and strategy and then fluoroscopic recording of the PulseRider delivery and subsequent coiling phase. Nuances of technique for this new device used in a challenging setting are discussed.The video can be found here: https://youtu.be/ont7ggqgLH8.

Revascularization Procedures

The optimal management strategy of patients with concomitant anterior communicating artery aneurysm (ACoAA) and internal carotid artery (ICA) stenosis is unclear. This study aims to evaluate the impacts of unilateral ICA revascularization on hemodynamics factors associated with rupture in an ACoAA. In the present study, a multiscale computational model of ACoAA was developed by coupling zero-dimensional (0D) models of the cerebral vascular system with a three-dimensional (3D) patient-specific ACoAA model. Distributions of flow patterns, wall shear stress (WSS), relative residence time (RRT) and oscillating shear index (OSI) in the ACoAA under left ICA revascularization procedure were quantitatively assessed by using transient computational fluid dynamics (CFD) simulations. Our results showed that the revascularization procedures significantly changed the hemodynamic environments in the ACoAA. The flow disturbance in the ACoAA was enhanced by the resumed flow from the affected side. In addition, higher OSI (0.057 vs. 0.02), prolonged RRT (1.14 vs. 0.39) and larger low WSS area (66 vs. 50 mm2) in ACoAA were found in the non-stenotic case. These acute changes in hemodynamics after revascularization may elevate the rupture risk of ACoAA. The preliminary results validated the feasibility of predicting aneurismal hemodynamics characteristics in revascularization procedures by using multiscale CFD simulations, which would benefit the management of this group of patients.

Abstract OBJECTIVE AND IMPORTANCE: The present case report is the first one to report a bilateral anastomotic artery between the internal carotid artery and the anterior communicating artery in the presence of a bilateral A1 segment, fenestrated anterior communicating artery (AComA), and associated aneurysm of the AComA, which was discovered by magnetic resonance angiography and treated surgically. CLINICAL PRESENTATION: A 38-year-old man who was previously in good health experienced a sudden onset of nuchal headache, vomiting, and confusion. Computed tomography revealed a subarachnoid hemorrhage. Magnetic resonance angiography and four-vessel angiography documented an aneurysm of the AComA and two anastomotic vessels of common origin with the ophthalmic artery, between the internal carotid artery and AComA. INTERVENTION: A fenestrated clip, introduced by a left pterional craniotomy, leaving in its loop the left A1 segment, sparing the perforating and hypothalamic arteries, excluded the aneurysm. CONCLUSION: The postoperative course was uneventful, with complete recovery. Follow-up angiograms documented the successful exclusion of the aneurysm. Defining this particular internal carotid-anterior cerebral artery anastomosis as an infraoptic anterior cerebral artery is not appropriate because there is already an A1 segment in its habitual localization. Therefore, it is also thought that, embryologically, this anomaly is not a misplaced A1 segment but the persistence of an embryological vessel such as the variation of the primitive prechiasmatic arterial anastomosis. The favorable outcome for our patient suggests that surgical treatment may be appropriate for many patients with this anomaly because it provides a complete and definitive occlusion of the aneurysm.
