BACKGROUND: A spontaneous fusiform aneurysm in the middle cerebral artery (MCA) can present with both ischemic and hemorrhagic symptoms, but the clinical course and prognosis are unclear because of its rarity. CASE DESCRIPTION: An asymptomatic fusiform shape aneurysm was found in a branch of the right middle cerebral artery (MCA) incidentally on a medical check-up in a 51-year-old woman with no medical history. It was followed-up by magnetic resonance imaging every year with no medical treatment...

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...

Intracranial flow diversion has gained increasing popularity since the approval of the Pipeline Embolization Device (PED). Although it is only approved for use in adult patients, the PED has been used to treat aneurysms in pediatric patients. We present the first reported case of the use of a PED in a pediatric patient to treat an unusual fusiform distal anterior cerebral artery aneurysm. A 12-year-old female presented with new onset seizures and was found to have an incidental distal left anterior cerebral artery aneurysm...

Use of the Pipeline embolization device (PED) has increased based on studies about its safety and effectiveness, and new reports that describe peri- or postprocedural complications are now emerging. We report a rare periprocedural device-related complication that occurred during endovascular treatment with the pipeline embolization device for a dissecting aneurysm on the vertebral artery. A 55-year old woman was admitted due to left medullary infarction, and angiography showed a fusiform dilatation in the left vertebral artery that was suspicious for dissecting aneurysm...

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...

Open aortic arch surgery after coronary artery bypass grafting (CABG) is considered a high-risk operation. We reviewed our surgical approach and outcomes to establish the risk profile for this patient population. In methods, from 2000-2014, 650 patients underwent aortic arch surgery with circulatory arrest. Of these, 45 (7%) had previous CABG. Complete medical record was available for review including all preoperative coronary angiograms and detailed management of myocardial protection. In results, the mean interval from previous CABG to aortic arch surgery was 6...

OBJECTIVES: In recent years, endovascular abdominal aortic aneurysm repair (EVAR) for treating abdominal aortic aneurysms (AAA) has become quite prevalent in Japan. Though little information is available about temporal changes in proximal neck angulation due to the difficulties encountered in measuring the angle. Therefore, we examined temporal changes in proximal neck angulation and its relationship to stent graft migration after endovascular abdominal aortic aneurysm repair. METHODS: Between June 2007 and March 2010, 159 patients underwent EVAR for treatment of fusiform abdominal aortic aneurysms at our hospital...

We present a retrospective analysis of endovascular treatments for posterior cerebral artery (PCA) aneurysms and discuss the susceptibility of a fetal-type PCA to vascular insufficiency after parent artery occlusion. Among 1207 aneurysms treated with endovascular therapy between March 1997 and March 2013 in our institution, 10 patients (0.8%) presented PCA aneurysms. The principal strategy was to employ selective coil embolization for the aneurysm. However, in certain cases of fusiform or dissecting aneurysms, we performed parent artery occlusion with coils...

Intracranial dissecting aneurysms have been frequently reported to present with fairly challenging and time-variable imaging findings that can be mostly explained by the pathological mechanisms that underline the dissection. We present two cases of spontaneous dissecting aneurysm of the supraclinoid ICA, both clinically presenting with SAH, but characterized by different progression of clinical symptoms and imaging. However, in both cases an outpouch and a mild fusiform dilation of the supraclinoid ICA was present in the initial CTA performed after the occurrence of symptoms...

The authors present a unique case of intracranial lipoma in the interpeduncular cistern associated with proximal P1 segment fenestration. This patient is a 20-year-old male with extensive psychiatric history and complaints of recent auditory hallucinations. Cranial magnetic resonance imaging (MRI) (T1, T2, and FLAIR) showed a hyperintense lesion in the left aspect of interpeduncular cistern with a prominent flow void within the hyperintense lesion suggestive of a combined vascular-lipomatous lesion. Computed tomography (CT) angiography showed a high-riding large tortuous P1 segment on the left side with proximal fenestration, the ectatic posteromedial limb harboring a fusiform dilated segment...

Intracranial circumferential fusiform aneurysms of the posterior circulation involving arterial branches or perforating vessels are difficult to treat. This article shows an endovascular reconstruction technique not yet described, using a telescoping self-expandable stent (LEO+) and flow-diverter device (SILK) at different surgical times. Two patients with circumferential fusiform aneurysm, one being an aneurysm of the segments P2 and P3 of the posterior cerebral artery, diagnosed after a headache, and the other a partially thrombosed aneurysm of the lower basilar artery, diagnosed following ischemia of the brain stem...
