PURPOSE: Large vertebral and basilar fusiform aneurysms (VFA) are sometimes difficult to cure by endovascular treatment (EVT). We aimed to elucidate indicators of poor outcomes of EVT in patients with VFAs. METHODS: Clinical data from 48 patients with 48 unruptured VFAs in the Hyogo Medical University were retrospectively analyzed. The primary outcome was defined as satisfactory aneurysm occlusion (SAO) according to Raymond-Roy grading scale. The secondary and safety outcomes were a modified Rankin scale (mRS) score of 0-2 at 90 days, retreatment, major stroke, and aneurysm-related death after EVT...

BACKGROUND: Flow-diverting devices (FDDs), such as the Pipeline Embolization Device, have been gaining traction for treating challenging posterior circulation aneurysms. Few previous studies have focused on using FDDs to treat aneurysms of the basilar quadrifurcation. METHODS: We retrospectively reviewed the use of FDDs to treat patients with basilar quadrifurcation aneurysms. Patients were assessed for aneurysm type, previous aneurysm treatment, technical success, periprocedural complications, and long-term aneurysm occlusion...

BACKGROUND: pCONus2 device has been used in some countries as coadyuvant in the treatment of wide-neck bifurcation aneurysms with coils. OBJECTIVE: To present the first series of brain aneurysms treated with pCONus2 in the Mexican Institute for Social Security (IMSS). MATERIAL AND METHODS: We retrospectively present the first 13 aneurysms treated from October 2019 to February 2022 with pCONus2 device at a third level hospital. RESULTS: 6 aneurysms located at anterior communicating artery, 3 at middle cerebral artery bifurcation, 2 at internal carotid artery bifurcatión, and 2 at the tip of basilar artery were treated...

PulseRider (Cerenovus, Irvine, CA, USA) is a relatively novel device used for the treatment of wide-neck aneurysms with a coil-assisted effect. However, treatment options for recurrent aneurysms after PulseRider-assisted coil embolization remain controversial. Here we report a case of recurrent basilar tip aneurysm (BTA) treated with Enterprise 2 after PulseRider-assisted coil embolization. A woman in her 70s underwent coil embolization for a subarachnoid hemorrhage with ruptured BTA 16 years ago. Recurrence was detected at 6-year follow-up, and an additional coil embolization was performed...

BACKGROUND: Cerebral hyperperfusion syndrome (CHS) occurs after the restoration of blood flow to a previously low-flow, low-pressure region of the cerebral vasculature, which subsequently responds with chronic compensatory vasodilation, leading to a dysregulated state. Sudden restoration of normal blood flow can overwhelm the vasculature leading to intracranial hemorrhage (ICH). Separately, the Windkessel phenomenon describes the capacity for elastic vessels to expand with systolic pressure and decompress with diastole, thereby suppressing distal pulse pressure...

BACKGROUND AND PURPOSE: Stent-assisted coiling of wide neck bifurcation aneurysms in the anterior communicating segment and basilar tip region can be performed with varying stent configurations, including single stenting or Y-stenting. Y-stenting requires two stents and thus incurs greater cost and procedural complexity than single-stent constructs. The influence of first stent type on the need for Y-stenting remains unknown. MATERIALS AND METHODS: Clinical and angiographic data were retrospectively obtained for patients that underwent stent-assisted coiling for basilar tip or anterior communicating aneurysms at a high-volume center...

OBJECTIVE: The use of a flow diverter (FD) in the treatment of ruptured aneurysms is limited due to the increased risk of perioperative ischemia and hemorrhagic complications. Adjunctive coil embolization and an evidence-based antithrombotic regimen may improve therapeutic safety, although evidence from relevant clinical research is limited. The authors' aim was to further assess the perioperative safety and long-term efficacy of this strategy. METHODS: Data on patients with FD insertion and coil embolization were collected retrospectively at two centers...

Congenital absence of the internal carotid artery (ICA) is an extremely rare entity that occurs due to insult during the embryonic development of the ICA. Various intracranial collateral pathways develop to compensate for the ICA agenesis. Patients can present with aneurysmal subarachnoid hemorrhage, stroke-like symptoms, or other neurological symptoms due to compression of brain structures from enlarged collateral pathways/aneurysms. We present two cases of ICA agenesis along with an extensive review of the literature...

The Anterior Inferior Cerebellar Artery-Posterior Inferior Cerebellar Artery (AICA-PICA) common trunk is a rare variant of cerebral posterior circulation in which a single vessel originating from either the basilar or vertebral arteries supplies both cerebellum and brainstem territories. We present the first case of an unruptured right AICA-PICA aneurysm treated with flow diversion using a Shield-enhanced pipeline endovascular device (PED, VANTAGE Embolization Device with Shield Technology, Medtronic, Canada)...

PURPOSE: Coil embolization is one of the main endovascular treatment for basilar apex aneurysms (BAAs), and thromboembolic events are important complications of coil embolization. Even in small aneurysms, there is a risk of rupture, and aggressive treatment should be considered for unruptured BAAs. Using diffusion-weighted imaging (DWI), the study aimed to investigate thromboembolic events after coil embolization for unruptured BAAs by focusing on the absolute aneurysm size and relative aneurysm size (size ratio [SR])...

OBJECTIVES: Flow diverter or stent implantation to intracranial target lesion requires large inner diameter microcatheter navigation. The exchange method using stiff long wire is often necessary if it is difficult to navigate over the regular guidewire. However, this method has an intrinsic risk of vessel damage and may cause severe complications. We investigated the safety and efficacy of a new device, the Stabilizer device for navigation in a first-in-human clinical trial under the Certified Review Board agreement...

BACKGROUND: Cerebrovascular embryologic development is characterized by the presence of four well-described carotid-vertebrobasilar (VB) anastomoses. As the fetal hindbrain matures and the VB system develops, these connections involute, yet some may persist into adulthood. The persistent primitive trigeminal artery (PPTA) is the most common of these anastomoses. In this report, we describe a unique variant of the PPTA and a four-way division of the VB circulation.

Basilar perforating artery aneurysms are rare and underreported vascular anomalies in the cerebrovascular literature. Various open and endovascular treatment approaches can be employed to treat these aneurysms based on several patient- and aneurysm-specific factors. Some authors have even advocated for conservative, nonoperative management. Here, we report a case of a ruptured distal basilar perforating artery aneurysm secured by an open transpetrosal approach. A 67-year-old male presented to our institution with a Hunt-Hess grade 2, modified Fisher grade 3 subarachnoid hemorrhage (SAH)...

A middle-aged patient presented with subarachnoid hemorrhage and was found to have a ruptured superior cerebellar artery (SCA) aneurysm arising from the origin of a rare anastomotic branch between the right SCA and right posterior cerebral artery (PCA). The aneurysm was secured by transradial coil embolization, and the patient made a good functional recovery. This case demonstrates an aneurysm arising from an anastomotic branch between the SCA and PCA, which may represent a remnant of a persistent primordial hindbrain channel...

BACKGROUND: Treatment of intracranial wide-necked bifurcation aneurysms remains challenging. We report a novel PulseRider "jack-up" technique for the treatment of wide-necked basilar tip aneurysms.

Aneurysm neck diameters ranged between 7.6 and 11 mm and dome-to-neck ratios ranged from 1.0 to 1.15. All three aneurysms were very shallow with aspect ratios of 0...

BACKGROUND: There is no established adequate treatment for thrombosed aneurysm of the basilar artery with obstructive hydrocephalus.
