Pediatric stroke is considered to be rare. Stroke resulting from cerebral vasculitis is also uncommon in young children. With the increasing prevalence of Kawasaki disease (KD) diagnosis, this acquired vasculitis has been reported with various clinical presentations including neurological symptoms. Herein we describe the case of a KD patient presenting with stroke. A 15-month-old boy was referred due to stroke that occurred on the fifth day of febrile illness. He was initially admitted to another hospital due to fever and diarrhea...

BACKGROUND: Ruptured intracranial fusiform aneurysms involving small-diameter parent arteries are difficult to treat. Parent artery occlusion is a relatively simple and reliable treatment. However, occasionally, the parent arteries have to be retained. The arrival of the low-profile stent (LVIS(TM) Jr.) has made reconstructive endovascular treatment for fusiform aneurysms involving small-diameter parent arteries possible. CASE DESCRIPTION: This report describes an innovative method for stent-assisted coiling (stenting after coiling technique using only one microcatheter), and describes our initial experience and feasibility of this technique...

INTRODUCTION: Traumatic intracranial aneurysms in children are rare and may occur as the result of closed or penetrating head trauma. Their natural history seems to be more aggressive. Most traumatic aneurysms have complex shape, tending to have a large neck or even a fusiform morphology. CASE REPORT: We present a case of a traumatic carotid artery aneurysm in a 9-year-old girl that was successfully treated with pipeline embolization device. DISCUSSION: Due to its dissecting nature, wall friability and lack of a substantial neck can make surgical clipping and selective coiling difficult and risky...

OBJECTIVE The Pipeline Embolization Device (PED) is now a well-established option for the treatment of giant or complex aneurysms, especially those arising from the anterior circulation. Considering the purpose of such treatment is to maintain patency of the parent vessel, postembolization occlusion of the parent artery can be regarded as an untoward outcome. Antiplatelet therapy in the posttreatment period is therefore required to minimize such events. Here, the authors present a series of patients with anterior circulation aneurysms treated with the PED who subsequently experienced parent vessel occlusion (PVO)...

BACKGROUND AND PURPOSE: Locally compacting the mesh of a flow diverter by a dynamic push-pull technique can accelerate intracranial aneurysm healing. We asked how this deployment strategy compares with overlapping 2 flow diverters for aneurysmal flow reduction. MATERIALS AND METHODS: Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompacted, 2 overlapped, and single compacted) in 3 aneurysms (fusiform, large saccular, and medium saccular)...

Venous aneurysms of the jugular vein are one of the rare causes of neck swelling, and primary venous aneurysms of the external jugular vein are extremely rare. A 46-year-old woman presented with a painless and suddenly growing mass in the left neck. A computed tomography angiography revealed a fusiform venous aneurysm of the external jugular vein containing intraluminal thrombus. We performed resection of the aneurysm and ligation of the external jugular vein. Removal of the aneurysm of the neck vein was necessary because venous aneurysms with thrombosis may lead to serious thrombotic complications such as pulmonary embolism...

Treatment of complex aneurysms using microsurgical and other conventional neuroendovascular techniques remains challenging. As a result, stent- and balloon-assisted coiling are instead performed to treat morphologically complex aneurysms, which include giant, wide-necked, and fusiform aneurysms. While these techniques have had success in treating these complex aneurysms, recanalization rates associated with these techniques are still problematic. In the constant effort to improve the outcome of complex aneurysm treatment, flow-diverting stents (FDSs) have emerged in recent years as the preferred treatment...

OBJECTIVE: Low wall shear stress (WSS) has been reported to be associated with accelerated atherosclerosis, aneurysm growth, or rupture. We evaluated the geometry of aortic arch aneurysms and their relationship with WSS by using the 4-dimensional flow magnetic resonance imaging to better characterize the saccular aneurysms. METHODS: We analyzed the geometry in 100 patients using multiplanar reconstruction of computed tomography. We evaluated WSS and vortex flow using 4-dimensional flow magnetic resonance imaging in 16 of them, which were compared with 8 age-matched control subjects and eight healthy young volunteers...

The aim of the study was to assess differences in ECG features and prevalence of comorbidies between two groups of patiens: with Abdominal Aortic Aneurism (AAA) and Aorto-Iliac Occlusive Desieses-Lerish Syndrome (LS). Data was collected for all consecutive adult patients who underwent elective surgical repair of AAA (fusiform aneurysm) or LS at "The Center of Vascular and Heart Diseases" (Tbilisi, Georgia) between 2010 and 2014. We studied a prevalence of Arterial Hypertension (AHT); Diabetes mellitus (DM); Renal Failure (RF),Peripheral Artery Disease (PAD), Coronary Artery Disease (CAD) and rate of coronary revascularization in these patients; We also, investigate some of the electrocariographic characteristics: Corrected QT interval(QTC),QT dispersion(QTD)...

BACKGROUND: and Importance: Microsurgical treatment for vertebral artery aneurysms can be approached through the lateral aspect of the brainstem and cerebellum. Contralateral approach may be selected in case of complex aneurysms with tortuous running, and the intracranial vertebral artery distal to the aneurysm locates in contralateral cerebello-pontine angle. When performing the aneurysm repair, exposing the V3 segment before craniotomy is advantageous. We describe the detailed surgical procedures about contralateral transcondylar fossa approach with bilateral V3 segment exposure for the repair of a complex vertebral artery aneurysm...

INTRODUCTION: Aortitis is a well recognized manifestation of the tertiary stage of syphilis. EVIDENCE ACQUISITION: Although often regarded as an unexpected diagnosis, actually new cases of cardiovascular syphilis continue to be reported. Presumably, Treponema pallidum invades the aortic wall and the inflammatory response progresses towards obliterative endarteritis and necrosis of the muscular and elastic fibers in the aortic media. The consequent weakening of the aortic wall can lead to severe complications, represented by aortic aneurysm, aortic valvular insufficiency, aortic root dilation and coronary ostial stenosis...

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...
