The treatment of intracranial complicated aneurysms remains challenging. In patients with complicated aneurysms that are neither clippable nor coilable, flow alteration treatment (FAT) with a combined procedure of proximal/distal occlusion or trapping of an aneurysm with bypass surgery has been reported. However, it is difficult to predict whatever FAT can achieve aneurysmal obliteration without ischemic complications. A 69-year-old female was incidentally diagnosed with a left vertebral artery (VA) fusiform aneurysm distal to the left posterior inferior cerebellar artery (PICA)...

BACKGROUND: Pediatric intracranial aneurysms (IAs) are rare. Compared to adult IAs, they are more commonly giant, fusiform, or dissecting. Their treatment often proves more complex and recurrence rate and de novo aneurysmogenesis incidence is higher. A consensus regarding the most appropriate algorithm for following pediatric IAs is lacking. METHODS: We thus sought to generate recommendations based on the reported experience in the literature with pediatric IAs, through a thorough review of the Pubmed database, discussion with experienced neurointerventionalists, and our own experience...

BACKGROUND: Intracranial fusiform aneurysm (IFA) is a relatively uncommon subgroup of aneurysms. There are few reports that focus on the hemodynamics of IFA. In this study, we compared the hemodynamics of the canine model of common carotid fusiform aneurysm and vertebrobasilar fusiform aneurysms in human patients. METHODS: Five male mongrel dogs were randomly chosen, and there unilateral common carotid artery (CCA) and external jugular vein were surgically exposed individually...

BACKGROUND: Various techniques have been used for wrap-clipping a ruptured, fusiform intracranial aneurysm. However, there is no available literature on use of the falx cerebri for wrap-clipping. OBJECTIVE: We present a review of the literature with an illustrative case, with a ruptured fusiform pericallosal artery aneurysm firmly attached to the lower edge of the falx cerebri and not amenable to endovascular intervention. METHODS: While the firm attachment between the inferior falx and the fusiform aneurysm was maintained, a section of the lower thinner part of the falx cerebri firmly attached to the aneurysm was dissected and wrapped around the fusiform aneurysm, stabilized with a fenestrated clip...

BACKGROUND: For some posterior inferior cerebellar artery (PICA) aneurysms, there is no constructive endovascular or direct surgical clipping option. Intracranial bypass is an alternative to a deconstructive technique. OBJECTIVE: To evaluate the clinical features, surgical techniques, and outcome of PICA aneurysms treated with bypass and obliteration of the diseased segment. METHODS: Retrospective review of PICA aneurysms treated via intracranial bypass was performed...

BACKGROUND: Fusiform intracranial aneurysms are challenging due to the circumferential nature of the disease. Endovascular parent vessel sacrifice with coils may be a treatment option, but typically requires a long vessel segment to induce complete cessation of flow. OBJECTIVE:   We evaluate early clinical experience with the intracranial use of the microvascular plug (MVP; Medtronic, Dublin, Ireland) device and to compare to previous coil-only techniques for vertebral artery sacrifice for fusiform vertebral aneurysm...

INTRODUCTION: Complex skull base approaches are frequently used to treat intracranial vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) aneurysms. These complex procedures are associated with higher risk of neurovascular injury. Hence, a less invasive surgical approach is needed to improve treatment's efficacy and safety. MATERIAL AND METHODS: A retrospective analysis was conducted on clinical and radiological data from surgeries where simple lateral suboccipital and "lateral enough" approaches were used to clip VA aneurysms in the Department of Neurosurgery at Helsinki University Central Hospital from 2000 - 2009...

INTRODUCTION: Treatment of large (≥20 mm) and giant (≥25 mm) intracranial aneurysms is challenging and can be associated with a high rate of morbidity and mortality. The Pipeline Embolization Device (PED) has been used effectively for the treatment of intracranial aneurysms achieving a high rate of complete occlusion. However, its safety and efficacy in treatment of large and giant aneurysms has not been evaluated fully. METHODS: A retrospective analysis of consecutive aneurysms treated with PED between 2009 and 2016 at 3 academic institutions within the United States was performed...

BACKGROUND: The prevalence of intracranial aneurysms (IAs) has been proposed to be elevated in the patients with neurofibromatosis type 1 (NF1). Our aims were to determine the prevalence of NF1 in a large Finnish population based cohort of IA patients and, on the other hand, the occurrences of subarachnoid haemorrhage and unruptured intracranial aneurysms in a nationwide population-based cohort of NF1 patients and its matched ten-fold control cohort. METHODS: The Kuopio IA Database (www...

PURPOSE: There is limited information available on the incidence of in-stent stenosis (ISS) secondary to the use of flow-diverting stents in the intracranial vasculature. We sought to determine the incidence, severity, and clinical course of ISS on angiographic follow-up after treatment of saccular aneurysms with p64. METHODS: We retrospectively reviewed all patients who underwent treatment of a saccular (ruptured and unruptured) intracranial aneurysm with ≥1 p64 between 2011 and 2015...

Flow diversion has revolutionised the treatment of intracranial aneurysms, and the Pipeline Embolization Device (PED) remains the only flow diverter (FD) approved in the USA. However, thromboembolic events remain an issue for FDs. Attempting to minimise these incidents, a newer PED has been developed with the use of covalent bonding of phosphorylcholine onto the Pipeline device that has been known as Shield Technology (PED Shield), which in vitro has demonstrated a significant reduction in material thrombogenicity...

OBJECTIVE: Early case series suggest that the recently introduced Low-profile Visualized Intraluminal Support Junior (LVIS Jr.) device (MicroVention-Terumo, Inc., Tustin, CA) may be used to treat wide-necked aneurysms that would otherwise require treatment with intrasaccular devices or open surgery. We report our single-center experience utilizing LVIS Jr. to treat intracranial aneurysms involving 1.8-2.5 mm parent arteries. METHODS: We retrospectively reviewed records of patients treated with the LVIS Jr...

BACKGROUND: The Pipeline Embolization Device (PED) is increasingly used for both on- and off-label purposes for treatment of intracranial aneurysms. The device gradually slows flow of blood into the aneurysm, but the high metal coverage of PED promotes endothelialization of the device. Occasionally, this leads to in-stent stenosis that is clinically well tolerated. We present a multi-institutional Pipeline series that includes three cases of gradual asymptomatic occlusion within the PED and parent vessel...

Revascularization techniques are being featured more prominently as endovascular treatments continue to select out complex cerebrovascular pathologies for open surgical management. The current healthcare environment requires decreased hospital stays and improved clinical outcomes despite the growing complexity of open surgical cases. Recent efforts to reduce operative room time and decrease risk for bypass surgery have focused on avoiding graft harvest and maintaining the entire bypass intracranial. The presented technique features an arborization bypass to serially anastomose the middle cerebral artery vessels allowing for proximal trapping of a complex aneurysm without graft harvest...

OBJECTIVE Fusiform cerebral aneurysms represent a small portion of intracranial aneurysms; differ in natural history, anatomy, and pathology; and can be difficult to treat compared with saccular aneurysms. The purpose of this study was to examine the techniques of treatment of ruptured and unruptured fusiform intracranial aneurysms and patient outcomes. METHODS In 45 patients with fusiform aneurysms, the authors retrospectively reviewed the presentation, location, and shape of the aneurysm; the microsurgical technique; the outcome at discharge and last follow-up; and the change in the aneurysm at last angiographic follow-up...

We present the first and only case, reported in literature, of a 67-years-old man with a mycotic aneurysm (MA) of the left posterior inferior cerebellar artery (PICA), caused by group B Streptococcus, that we surgically treated, performing neck aneurysm clipping, preserving patency of parent vessel. Moreover the peculiarity of this case is represented by the fact that the MA is originated from a tooth abscess, treated about two years before. To date, there have been only 10 cases of association between MA with either tooth pathologies or dental surgical procedures and our case is the only one originating from PICA...
