OBJECTIVE: This study aimed to propose a modified classification of spontaneous intracranial dissecting aneurysms (IDAs) and to guide the treatment for IDAs. METHODS: Between January 2010 and December 2015, 3183 consecutive patients were referred to our department for endovascular treatment of a cerebral aneurysm and 309 patients harboring 323 spontaneous IDAs were identified from them. Based on a modified imaging classification, spontaneous IDAs were classified into four subtypes: classic dissecting aneurysm, segmental ectasia, dolichoectatic dissecting aneurysm, and large mural bleeding ectasia...

In vivo measurement of blood velocity fields and flow descriptors remains challenging due to image artifacts and limited resolution of current imaging methods; however, in vivo imaging data can be used to inform and validate patient-specific computational fluid dynamics (CFD) models. Image-based CFD can be particularly useful for planning surgical interventions in complicated cases such as fusiform aneurysms of the basilar artery, where it is crucial to alter pathological hemodynamics while preserving flow to the distal vasculature...

BACKGROUND AND PURPOSE: Rabbit elastase-induced saccular aneurysms have been commonly used for preclinical testing of endovascular devices, including flow diverters. However, all tested devices have been shown to be capable of aneurysm occlusion with this model. We aimed to create a more challenging model to test and discriminate among neurovascular devices of varying efficacies. MATERIALS AND METHODS: With a surgical approach that included elastase infusion and balloon dilation, we attempted the creation of complex fusiform aneurysms in 16 rabbits, with standard saccular carotid aneurysms created in 15 other animals...

Central retinal artery occlusion (CRAO) is a devastating ocular emergency characterized by acute painless visual loss in the ipsilateral eye. We describe the case of acute non-arteritic CRAO associated fusiform internal carotid-ophthalmic artery aneurysm with intraluminal thrombus. Despite the rarity of this condition, we suggest that carotid-ophthalmic artery aneurysm should be included in the differential diagnosis of CRAO.

Aneurysms of the anterior cerebral artery (ACA) located distal to the anterior communicating artery complex (ACOM) remain challenging to treat with surgical clip reconstruction as well as with endovascular coil-embolization strategies. We have treated five complex geometry distal ACA aneurysms with endoluminal reconstruction using the Pipeline Embolization Device (PED). Two aneurysms were of the dysplastic fusiform type. Three aneurysms were of complex saccular configuration. Three aneurysms were treated electively at the outset with PED...

An aneurysm of the distal superior cerebellar artery (SCA) is a highly rare disease. Fusiform aneurysms of the distal SCA are particularly challenging to treat. Clipping, trapping with or without bypass using microsurgery or endovascular treatment (EVT) were used to treat this condition. We describe the case of fusiform distal SCA aneurysms treated successfully with endovascular coiling with a 3-month follow-up. A 39 year-old male was presented with subarachnoid hemorrhage (SAH) and a 15 mm fusiform aneurysm of the ambient segment of the left distal SCA...

BACKGROUND AND PURPOSE: Non-saccular aneurysms of the posterior fossa are an uncommon pathology with no clear treatment strategy. The use of flow-diverting stents (FDS) has had mixed results. We sought to evaluate our experience of FDS for the treatment of this pathology. METHODS: We retrospectively reviewed our database of prospectively collected information for all patients treated only with flow diversion for an unruptured non-saccular aneurysm of the posterior circulation between February 2009 and April 2016...

Congenital brachial artery true aneurysms are exceedingly rare. Most are pseudoaneurysms secondary to trauma or infection. We report a boy aged 2 years who presented with painless, pulsatile swelling on the medial aspect of the right arm, 4 cm above the elbow joint that had been present since birth. Spiral CT angiography showed a fusiform aneurysm of the distal right brachial artery with a peripheral crescent-shaped thrombus. Distal arteries were normally opacified. There was no evidence of abnormal dilation or stenosis in any other artery...

OBJECTIVE Risk of ischemia during aneurysm surgery is significantly related to temporary clipping time and final clipping that might incorporate a perforator. In this study, the authors attempted to assess the potential added benefit to patient outcomes of "awake" neurological testing when compared with standard neurophysiological testing performed under general anesthesia. The procedure is performed after the induction of conscious sedation, and for the neurological testing, the patient is fully awake. METHODS The authors conducted an institutional review board-approved prospective study of clipping unruptured intracranial aneurysms (UIAs) in 30 consecutive adult patients who underwent awake clipping...

BACKGROUND: Stent-assisted coiling is commonly used to treat wide-necked and fusiform cerebral aneurysms. We evaluated our institutional experience with stent-assisted coiling of cerebral aneurysms to elucidate potential risk factors for recurrence. METHODS: A retrospective analysis of patients undergoing stent-assisted coiling of cerebral aneurysms from 2005 to 2012 resulted in 122 patients with 122 aneurysms. Demographic, peri-procedural, medical comorbidity, and follow-up data were collected...

Aneurysms of the persistent trigeminal artery (PTA) trunk are exceptionally rare and have a high risk for rupture. Dual stent placement through each internal carotid and basilar artery for endovascular coil embolization of a fusiform aneurysm arising from the PTA has not been described in the literature. A 44-year-old female with a history of chronic headache was identified to have a fusiform aneurysm arising from medially coursing adult type, Saltzman type 3 PTA trunk. Sacrifice of the PTA trunk inclusive of the aneurysm was performed with dual stent placement through each basilar and internal carotid artery across their respective junctions with the PTA...
