BackgroundThe low profile visualized intraluminal support (LVIS) device is being increasingly used for the treatment of intracranial aneurysms. Its application in the basilar artery (BA) has not yet been reported.ObjectiveTo evaluate the safety and early efficacy of the LVIS device for the treatment of BA aneurysms.MethodsA prospectively maintained database was retrospectively reviewed for all patients with BA aneurysms treated by LVIS stents at our institution. Angiographic results were evaluated using the modified Raymond–Roy classification (mRRC).Results23 patients (mean age 52.8 years) with a BA aneurysm that was treated by LVIS stent implantation, with (n=21) or without (n=2) adjunctive coiling, were included in our study. 7 aneurysms were treated in the setting of subarachnoid hemorrhage (SAH). 10 aneurysms were located at the basilar tip, 10 at the basilar trunk, and 3 at the superior cerebellar artery. Procedure related complications developed in three patients (13%), including two perforator infarction and one worsening mass effect. Complications resulted in permanent morbidity (4%) in one case. One fatality was related to severe poor grade SAH. At a mean follow-up of 6.9 months, 13 of the 20 patients were mRRC I closure, 3 were mRRC II closure with an improvement from class IIIa, 3 were observed to be recanalized from class IIIa to IIIb, and 1 with stenting only was still patent similar to the immediate angiography.ConclusionThe LVIS stent represents a feasible and safe option for endovascular embolization of BA aneurysms. Although recanalization may occur after LVIS treatment, the mid term complete occlusion rate was acceptable.

Abstract Background The Low-profile Visualized Intraluminal Support (LVIS) device is a self-expanding, nitinol, single-braid, closed-cell device that was recently developed for endovascular embolization of intracranial aneurysms. However, current knowledge regarding the use of LVIS devices to treat vertebral and basilar artery aneurysms is limited. We aimed to evaluate the feasibility, efficacy, and safety of the LVIS device for treating vertebral and basilar artery aneurysms. Methods Between January 2015 and December 2017, patients with vertebral and basilar artery aneurysms treated using LVIS stents were enrolled in this study. We analyzed patients’ demographic, clinical and aneurysmal characteristics, procedural details, complications, and angiographic and clinical follow-up results. Results We identified 63 patients with 64 vertebral and basilar artery aneurysms who underwent treatment with (n = 59) or without (n = 5) LVIS stenting, including 10 patients with ruptured aneurysms. Forty-one aneurysms were located at the vertebral artery, and 23 at the basilar artery. Intraprocedural-related complications developed in three (4.8%) patients, while none of these patients developed morbidities or died during follow-up. Three patients developed post-procedural complications (4.8%). Two patients experienced ischemic events immediately post-procedure. A minor permanent morbidity developed in one of the two patients (1.6%). The mortality rate was 1.6%, for that the patient died of brainstem hemorrhage after 1 month of follow-up. At a mean follow-up of 12.5 months, 39/43 (90.7%) patients had stable or improved aneurysms, and four (9.3%) had recanalized. Conclusions LVIS device of vertebral and basilar artery aneurysms may be an acceptable safety profile and may represent a reasonable treatment option in the short-term. Long-term and larger cohort studies are necessary to validate our results.

IntroductionThe LVIS Blue is an FDA-approved stent with 28% metallic coverage that is indicated for use in conjunction with coil embolization for the treatment of intracranial aneurysms. Given a porosity similar to approved flow diverters and higher than currently available intracranial stents, we sought to evaluate the effectiveness of this device for the treatment of intracranial aneurysms.MethodsWe performed an observational single-center study to evaluate initial occlusion and occlusion at 6-month follow-up for patients treated with the LVIS Blue in conjunction with coil embolization at our institution using the modified Raymond–Roy classification (mRRC), where mRRC 1 indicates complete embolization, mRRC 2 persistent opacification of the aneurysm neck, mRRC 3a filling of the aneurysm dome within coil interstices, and mRRC 3b filling of the aneurysm dome.ResultsSixteen aneurysms were treated with the LVIS Blue device in conjunction with coil embolization with 6-month angiographic follow-up. Aneurysms were treated throughout the intracranial circulation: five proximal internal carotid artery (ICA) (ophthalmic or communicating segments), two superior cerebellar artery, two ICA terminus, two anterior communicating artery, two distal middle cerebral artery, one posterior inferior cerebellar artery, and two basilar tip aneurysms. Post-procedurally, there was one mRRC 1 closure, five mRRC 2 closures, and 10 mRRC 3a or 3b occlusion. At follow-up, all the mRRC 1 and mRRC 3a closures, 85% of the mRRC 3b closures and 75% of the mRRC 2 closures were stable or improved to an mRRC 1 or 2 at follow-up.ConclusionsThe LVIS Blue represents a safe option as a coil adjunct for endovascular embolization within both the proximal and distal anterior and posterior circulation.

Background: Giant brain aneurysms account for approximately 5% of all intracranial aneurysms, often presenting with intraluminal thrombosis that causes a mass effect in surrounding neural structures. Although its exact growing mechanism remains unknown, they have to be treated. Despite the most recent advances in neurosurgical fields, the best treatment modality remains unknown and surgery of giant superior cerebellar artery (SCA) aneurysms still is a challenge even for the most experienced neurosurgeons, due to their deep location, surrounding perforating vessels, and intraluminal thrombosis. Case Description: In this video, we present the case of a 65-year-old woman with progressive hemiparesis and paresis of low cranial nerves. The symptoms were caused by a giant aneurysm located in the origin of the SCA. Despite endovascular embolization of the aneurysm and placement of a flow diverter stent, the aneurysm increased in size causing symptoms progression. In that scenario, we decided to perform a microsurgical decompression of the aneurysm thrombus and coagulation of the vasa vasorum, to reduce the mass effect and prevent the aneurysm from keep growing. Conclusion: Through an extensive description of the surgical anatomy, we illustrate an interhemispheric transcallosal transforaminal approach, with the removal of anterior thalamic tubercle to widely expose the aneurysm dome. The surgery was successfully performed, and the patient symptoms improved. The patient signed the Institutional Consent Form, which allows the use of her images and videos for any type of medical publications in conferences and/or scientific articles.

Background: Hemodynamic flow is one of the major factors in the progression and rupture of intracranial aneurysms (IA). Flow diverter devices (FD) reduce blood flow in the aneurysm sac, allow gradual stagnation, thrombosis and neointimal remodeling while maintain outflow in the side branches and perforators. Objectives: We present our experience and long-term follow-up on endovascular reconstruction of complexes IA using flow diverter device. Particularly we analyze our experience with (Pipeline endovascular device) PED. Methods: Since March 2006 to July 2015, 1000 patients (pt) with IA were treated with FD or FD/coils. Of this group 633 pt were with PED, 113 Surpass (SNEG), 111 P64, 78 Cardiatis, 40 WEB and others 25. Angiographic follow-up was performed at 3, 6, 12 months and yearly until 8 y Fup. An inclusion criteria was unfavorable anatomy for coil, dome to neck ratio ≥ 2, Neck ≥ 4 mm and recurrence following previous treatment. Results: We treated 633 Pt with 704 IA with 932 PED. (77 % female); mean age 55 y (range 7-88). History of SAH was present in 18,5%; 81,5% were unruptured IA; mass effect in 125 pt; incidental IA 96 pts; headache 77 pts, others 23 pts. Large/giant IA were present in 51,2%, and wide neck (>4mm) 65%. The technical success was 98,4%. Occlusion rate at 1yr was 90 % and 8 yr 100 %, without recurrences. Peri-procedural (30 days) morbi-mortality rate was 5.9%: 2.7% had definitive neurologic defects; death rate was 3.2%. Conclusion: Endovascular treatment of complex IA with FD is a safe, effective and stable procedure, with an acceptable morbi-mortality rate.

Background:Superior cerebellar artery aneurysms are rare. We present a clinical series of twelve of these aneurysms that were treated exclusively with endovascular coils.Method:A retrospective analysis of a prospectively collected database of cerebral aneurysms treated with coil embolization was performed. Clinical notes and radiological images were reviewed.Results:Twelve superior cerebellar artery aneurysms were treated in eleven patients between 1992 and 2001. Seven patients presented with subarachnoid hemorrhage, two with neurologic deficit, and two had asymptomatic aneurysms. Coiling resulted in complete aneurysm obliteration in six patients and incomplete obliteration in the other six. No subsequent hemorrhage occurred with follow-up between 6 and 119 months (mean follow-up 50 months). Procedural morbidity was one superior cerebellar artery infarct with good recovery. Management morbidity was one middle cerebral artery embolus during a follow-up angiogram that required thrombolysis with a good clinical result. Nine out of 11 patients on follow-up were performing at Glasgow Outcome Scale (GOS) 5. One patient with GOS 3 presented with a poor grade subarachnoid hemorrhage and the other patient with GOS 4 presented with a parenchymal hemorrhage due to an arteriovenous malformation.Conclusion:Endovascular treatment of superior cerebellar artery aneurysms is an effective treatment strategy with low morbidity.

The authors present the unusual case of a complex unruptured basilar artery terminus (BAT) aneurysm in a 42-year-old symptomatic female patient presenting with symptoms of mass effect. Due to the fusiform incorporation of both the BAT and left superior cerebellar artery (SCA) origin, simple surgical or endovascular treatment options were not feasible in this case. A 2-staged (combined deconstructive/reconstructive) procedure was successfully performed: first occluding the left SCA with a Pipeline embolization device (PED) coupled to a microvascular plug (MVP) in the absence of antiplatelet coverage, followed by reconstruction of the BAT by deploying a second PED from the right SCA into the basilar trunk. Six-month follow-up angiography confirmed uneventful aneurysm occlusion. The patient recovered well from her neurological symptoms. This case report illustrates the successful use of a combined staged deconstructive/reconstructive endovascular approach utilizing 2 endoluminal tools, PED and MVP, to reconstruct the BAT and occlude a complex aneurysm.

Purpose: Microcatheter navigation into an aneurysm sac can present difficulties through negative interactions between the deployed stent mesh and microcatheter. We hypothesized that endothelialization of the stent mesh would minimize these interactions. We aimed to assess the feasibility of staged coiling after stenting by reviewing our experiences with unavoidably staged embolization cases.Materials and Methods: Between 2011 and 2019, 7 patients (mean age 57.2 years, range 49–76 years) including 5 females, experienced 9 unruptured aneurysms treated with staged stenting and coiling due to unstable microcatheter navigation into the aneurysm after stent placement. The aneurysms were in the paraclinoid internal carotid artery (ICA) (n=3), ophthalmic origin ICA (n=1), superior cerebellar artery origin (n=2), basilar tip (n=2), and the middle cerebral artery bifurcation (n=1). The stents used were the Neuroform Atlas (n=4), Neuroform EZ (n=2), and Low-profile Visualized Intraluminal Support Blue (n=1).Results: The mean interval between stenting and coiling was 15 weeks (range, 12–21 weeks). The average navigation time between the first roadmap imaging and microcatheter insertion in the sac was 14 minutes (range, 8–20 minutes). One aneurysm was occluded without further coiling on follow-up. Staged coiling successfully treated the remaining aneurysms (n=8). No complications were identified.Conclusion: In cases of difficult intra-saccular catheterization, intentional staged coiling may be a feasible option for stent-assisted coiling of the cerebral aneurysms.
