“…[2] Fenestration refers to paired longitudinal nerve-artery fusion failure or bridging artery degeneration during embryonic development. [1–4,7–12] Basilar artery fenestration is the 2nd most common intracranial artery fenestration after anterior communicating fenestration. [1,7] Fenestration can occur at any part of the basilar artery, but it usually occurs at the proximal end near the vertebrobasilar artery junction.…”

“…Although fenestration at the middle and distal portions has been reported, it is very rare. [1,3,4,7,8,11] The incidence of basilar artery fenestration is 1% to 2.07% by magnetic resonance angiography, 0.28% to 6% by autopsy, and 0.02% to 0.6% by angiography. [2,4,8,9,12]…”

“…These factors contribute to aneurysm formation and growth. [1,4,7,8,10,12] Here, we report the very rare case of a patient with fenestration malformation and an aneurysm at the middle/distal junction of the basilar artery. The only case found in the PubMed database was previously reported by Tasker and Byrne.…”

Rationale: Fenestration of the basilar artery is most common in the proximal portion near the vertebrobasilar artery junction. Conversely, fenestration of the middle and distal portions of the basilar artery is not common, and fenestration of the basilar artery with an aneurysm is even less common. Patient concerns: This study reports the case of a 37-year-old woman with basilar artery fenestration malformation and an aneurysm at the mid-distal junction; her symptoms included sudden headaches with nausea and vomiting. Diagnoses: Head digital subtraction angiography showed fenestration at the junction of the middle and upper portions of the basilar artery associated with an aneurysm, and spontaneous pseudoaneurysm formation could not be excluded. Interventions: The patient underwent stent-assisted fenestration and channel occlusion. Outcomes: Five months later, no abnormalities were found by head magnetic resonance imaging. The stents were well positioned, and no occluded branches or aneurysms were present. Lessons: For mid-distal basilar artery fenestration malformation with an aneurysm, occlusion of the lesion channel is relatively safe when there are no perforating vessels in the fenestration channel and the lesion channel is a nondominant channel. Overall, more attention should be paid to the possibility of pseudoaneurysm formation in the diagnosis and treatment of this type of aneurysm.

“…Vertebrobasilar junction (VBJ) fenestration is a rare embryological variation with an incidence of 0.3–5.26% in autopsy series and 0.1–1.9% in angiography series. [ 1 ] Aneurysms associated with basilar artery fenestration were found in approximately 7% of cases while a higher incidence of aneurysms was observed at VBJ fenestration in approximately 35% of cases. [ 2 ] Surgical access to VBJ aneurysms (VBJAs) is difficult and complex in local anatomy due to the presence of brainstem perforators and cranial nerves.…”

Reverse Y stenting in the management of vertebrobasilar junction fenestrated aneurysm: A novel technique

Fenestrated aneurysm at vertebrobasilar junction (VBJ) is very rare and can occur due to non-fusion of longitudinal neural axis forming basilar artery in the early stage of embryonic life. Due to defects in tunica media and weakness in its wall, these fenestrations are more likely to develop an aneurysm. Various treatment strategies are required for the management of these types of aneurysms including simple coiling, stent-assisted coiling, balloon remodeling technique, and more recently kissing flow diverters. Herein, we report the case of ruptured fenestrated VBJ aneurysm which was managed successfully with novel reverse Y stenting with coiling.

“…The domestic and international research about 3D finite element model of IA is extremely popular, however, it is rare to see research about 3D finite element model of IA with fenestration. Fenestration of intracranial artery(FIA),also called the name of fenestrated cerebral artery, is a rare but well-known vascular variation [5][6]that begins with a common origin, splits into two distinct endothelium-lined channels, which then rejoin distally [7]. The size of the fenestration varies from approximately 1 mm to several centimeters in length.…”

Abstract. The diagnostic value of fenestration itself is limited but it is quite different when fenestration is accompanied by IA. In recent years, the reconstruction model of IA has become the domestic and international hot topic for discussion, however, it is rare to see the research about reconstruction model of IA with fenestration. Based on reliable CT imaging technologies and optimized modeling methods, we successfully reconstruct the 3D digital model of IA with fenestration by applying Mimics software combined with Geomagic studio software. This model can provide a necessary condition for the 3D finite element reconstruction model and computational fluid dynamic analysis, open a new approach for relative clinical hemodynamic study and operative treatment.
