A 33-year-old man presented with aneurysmal subarachnoid hemorrhage from a ruptured, blister-type sidewall internal carotid artery (ICA) aneurysm. Balloon-assisted coiling was performed with residual neck. He subsequently developed severe vasospasm requiring intra-arterial therapies on multiple occasions, during which it was noted that despite widespread vasospasm, a focal segment of the ICA at the site of the aneurysm showed no significant spasm, suggesting underlying vessel abnormality. He was discharged without deficit and scheduled for flow diversion given concern over this potentially pathologic segment of vessel...

Unruptured intracranial aneurysms (UIA) have a high prevalence (3.2%) and are increasingly diagnosed with modern imaging tools. The main risk of UIA is their rupture associated with intracranial bleeding with often severe clinical consequences. Areas covered: This review discusses the management strategy of UIAs, based on the large series of the literature (ISUIA, ATENA, UCAS, …), knowing that no randomized controlled trial is available to compare different strategies. The different endovascular treatments are described...

Background Double lumen balloon catheters (DLBCs) are currently used in the treatment of intracranial aneurysms, especially when involving balloon or stent-assisted coiling. The existing DLBCs allow the delivery of self-expandable stents but do not offer the possibility to deploy flow-diverters. Despite the increasing use and success of flow-diverters, there have been numerous reports of procedural complications such as early in-stent thrombosis or delayed distal embolization. It seems that these complications can be avoided by correct stent positioning and adequate wall apposition, achieved either by manoeuvres with the microguidewire and/or microcatheter or by performing balloon angioplasty following an exchange guidewire manoeuvre...

OBJECTIVE Even though published data exist concerning the prevalence of ischemic lesions detected by diffusion-weighted imaging (DWI) following endovascular treatment of intracranial aneurysms, a single-center cross-evaluation of the different endovascular techniques has been lacking. The authors sought to prospectively evaluate the prevalence and clinical significance of ischemic lesions occurring after endovascular treatment of intracranial aneurysms and to compare the safety and effectiveness of a broad spectrum of currently accepted endovascular techniques in a single-center setting...

The use of flow-diverting stents for intracranial aneurysms has become more prevalent, and flow diverters are now routinely used beyond their initial scope of approval at the proximal internal carotid artery. Although flow diversion for the treatment of cerebral aneurysms is becoming more commonplace, there have been no reports of its use to treat flow-related cerebral aneurysms associated with arteriovenous malformations (AVMs). The authors report the cases of 2 patients whose AVM-associated aneurysms were managed with flow diversion...

BACKGROUND: The prothrombotic milieu seen in subarachnoid hemorrhage (SAH) poses a unique challenge to neurovascular surgeons with regard to device use and microcatheter practice. OBJECTIVE: To determine how demographic factors and balloon practices impact diffusion-weighted imaging (DWI) abnormalities and outcomes in patients with SAH compared to those without (non-SAH). METHODS: We retrospectively analyzed 77 patients with SAH treated by balloon-assisted coiling in a single institution compared with 81 consecutive patients with unruptured aneurysms treated by balloon-assisted coiling at the same institution...

Duplication of the middle cerebral artery(MCA)is an anatomical variant of the MCA, originating from the distal portion of the internal carotid artery(ICA)and supplying blood flow to the tip of the temporal lobe. Cerebral aneurysms rarely develop at the bifurcation of the ICA and the duplicated MCA, but when they do develop, they may result in subarachnoid hemorrhage. We treated a 41-year-old man, who was urgently brought to our hospital because of severe headache. A computed tomography(CT)scan showed subarachnoid hemorrhage due to the rupture of an aneurysm at the origin of the duplicated MCA...

BACKGROUND AND PURPOSE: Simple coil embolization is often not a feasible treatment option in wide-neck aneurysms. Stent-assisted coil embolization helps stabilize the coils within the aneurysm. Permanent placement of a stent in an intracranial vessel, however, requires long-term platelet inhibition. Temporary stent-assisted coiling is an alternative technique for the treatment of wide-neck aneurysms. To date, only case reports and small case series have been published. Our purpose was to retrospectively analyze the effectiveness and safety of temporary stent-assisted coiling in a larger cohort...

BACKGROUND: Aneurysms of the cerebral vessels are relatively common and aneurysms of the ophthalmic segment of the internal carotid artery (ICA) represent approximately 10% of intradural aneurysms. ANATOMICAL ASPECTS: The ophthalmic segment of the ICA extends from the origin of the ophthalmic artery to the origin of the posterior communicating artery. Aneurysms can originate from the ophthalmic artery itself or directly from the ICA at a distance from the ophthalmic artery...

OBJECTIVE Intracranial bifurcation aneurysms are complex lesions for which current therapy, including simple coiling, balloon- or stent-assisted coiling, coil retention, or intrasaccular devices, is inadequate. Thromboembolic complications due to a large burden of intraluminal metal, impedance of access to side branches, and a high recurrence rate, due largely to the unmitigated high-pressure flow into the aneurysm (water hammer effect), are among the limitations imposed by current therapy. The authors describe herein a novel device, eCLIPs, and its use in a preclinical laboratory study that suggests the device's design and functional features may overcome many of these limitations...

An aneurysm is a balloon-like bulge in the wall of blood vessels, occurring in major arteries of the heart and brain. Biodegradable polymeric stent-assisted coiling is expected to be the ideal treatment of wide-neck complex aneurysms. This paper presents the development of methods to fabricate and optimally design biodegradable polymeric stents for aneurysms treatment. Firstly, a dispensing-based rapid prototyping (DBRP) system was developed to fabricate coil and zigzag structures of biodegradable polymeric stents...

OBJECTIVES: Aneurysms of the proximal posterior inferior cerebellar artery (PICA) are rare. The management of proximal PICA aneurysms is challenging with either surgical or endovascular treatment. We report our successful experience of treating PICA aneurysms with a multimodal approach. METHODS: Of 2382 treated aneurysms, 22 aneurysms in 21 patients (male:female 8:13, mean age 48.9 years) were enrolled from March 1998 to December 2015. We treated the aneurysms with a multimodal approach and performed angiography to examine aneurysm regrowth at the 12 months follow-up...
