BACKGROUND: Arteriovenous malformation (AVM)-associated aneurysms are common, being reported in 15% of cases. In regards to ruptured posterior fossa AVMs, associated aneurysms are present in 48% of cases and are the etiology of the bleed in 37%. We present a 75 year-old female who presented with a subarachnoid hemorrhage (SAH) secondary to a ruptured aneurysm arising from a flow-related basilar perforator artery feeder of an anterior pontine AVM. We report the successful treatment of the aneurysm with coil embolization...

PURPOSE: Growth of intracranial fusiform aneurysms (IFA) may become clinically problematic through a mass effect or rupture. We investigated the growth rate and factors contributing to growth in asymptomatic untreated IFA. METHOD: As a retrospective review, we assessed patients diagnosed with asymptomatic IFA between August 2000 and September 2014, all untreated. No acute or symptomatic dissecting lesions were considered. Clinical and serial angiographic follow-up data were analyzed, defining growth as expansion > 2 mm in one or more dimensions...

BACKGROUND: Stereotactic radiosurgery (SRS) is an established modality for the treatment of vestibular schwannomas (VSs). However, its long-term vascular complications have not been well-studied. Among the 360 patients who underwent SRS for VS in our institution and lived for >5 years thereafter, we identified only 1 patient who exhibited complication due to a late-onset aneurysm; thus, the incidence was roughly estimated to be 0.3%. CASE DESCRIPTION: The patient was a 78-year-old man who had undergone SRS for a right VS, and presented with right peripheral facial palsy 19 years later...

OBJECTIVE Flow diversion for posterior circulation aneurysms performed using the Pipeline embolization device (PED) constitutes an increasingly common off-label use for otherwise untreatable aneurysms. The safety and efficacy of this treatment modality has not been assessed in a multicenter study. METHODS A retrospective review of prospectively maintained databases at 8 academic institutions was performed for the years 2009 to 2016 to identify patients with posterior circulation aneurysms treated with PED placement...

OBJECTIVE The Pipeline embolization device (PED) has become a valuable tool in the treatment of cerebral aneurysms. Although failures with PED treatment have been reported, the characteristics and course of these aneurysms remain a topic of uncertainty. METHODS Electronic medical records and imaging studies were reviewed for all patients treated with the PED between July 2010 and March 2015 to identify characteristics of patients and aneurysms with residual filling after PED treatment. RESULTS Of 316 cases treated at a single institution, 281 patients had a long-term follow-up...

OBJECTIVE A direct comparison of endovascular versus microsurgical treatment of ruptured middle cerebral artery (MCA) aneurysms in randomized trials is lacking. As endovascular treatment strategies continue to evolve, the number of reports of endovascular treatment of these lesions is increasing. Herein, the authors report a detailed post hoc analysis of ruptured MCA aneurysms treated by microsurgical clipping from the Barrow Ruptured Aneurysm Trial (BRAT). METHODS The cases of patients enrolled in the BRAT who underwent microsurgical clipping for a ruptured MCA aneurysm were reviewed...

INTRODUCTION: Brachial artery aneurysms are relatively uncommon and generally due to infectious, post-traumatic or iatrogenic etiology. They seem to affect 4.5% of arteriovenous fistula. The usual manifestation is an accidental finding of a pulsatile, painless, and asymptomatic mass. Complications include sac thrombosis, thromboembolic ischaemic events, and disruption with profuse bleeding. METHODS: The aim of this study is to present a case of true brachial artery aneurysm in end-stage renal disease patient after arteriovenous fistula creation...

We describe a case of a 44 year-old man with a subcutaneous swelling in the left popliteal fossa. The patient complained pain posteriorly to the left knee since several months and presented with a saccular aneurysm of the left popliteal vein (PVA) with reflux clearly evidenced at duplex ultrasound scan (DUS), but in absence of thrombus inside and without clinical signs of embolism. The patient was treated surgically by aneurysmectomy with lateral venorrhaphy according to Aldridge technique and a duplex ultrasound scan after six months revealed a complete patency of the left popliteal vein...

Radiotherapy is a useful modality for the treatment of brain tumors, but may induce brain degeneration, tumor formation, and vasculopathy in the irradiated field. We describe a rare case of a pediatric patient who presented multiple different types of vascular events consecutively in the irradiated field including lacunar stroke because of occlusion of perforating artery, intraventricular hemorrhage from cavernoma, and subarachnoid hemorrhage because of the rupture of fusiform aneurysm, 6 years after radiotherapy against pilocytic astrocytoma...

PURPOSE: Endovascular stents are widely used for the elective treatment of cerebral aneurysms. Acute stenting is performed in the management of dissections, pseudo-aneurysms, broad-based aneurysms or as a 'bail out' measure after coil migration. The purpose of this study is to review the safety of using stents in acute subarachnoid haemorrhage. METHODS: The stent registry of our institution was reviewed for procedures in patients with acute subarachnoid haemorrhage...

We report 2 cases of parent artery occlusion (PAO) for anterior cerebral artery (ACA) fusiform aneurysm embolization after superselective provocative testing was performed to confirm distal territory viability. The first case involves a patient in the second decade of life who presented with subarachnoid hemorrhage and underwent PAO after a balloon test occlusion in the distal ACA revealed no neurophysiology changes. The second case involves another patient in the forth decade of life who presented with an enlarging pseudoaneurysm and underwent PAO after a sodium amobarbital infusion in the distal ACA revealed no clinical change...

Spinal aneurysms are rare lesions, and their natural history is not well known. In particular, aneurysms arising from the artery of Adamkiewicz (AA) are an extremely rare phenomenon, and given the lack of solid evidence its management remains unclear. We present the case of a 54-year-old woman with spinal subarachnoid hemorrhage. A spinal angiogram demonstrated a fusiform aneurysm arising from the AA. Based on the location, the absence of evident collateral circulation to the anterior spinal artery, and the available literature supporting spontaneous thrombosis, we opted for conservative management...

Posterior cerebral artery (PCA) aneurysms can be technically challenging lesions due to the intricacy of perforating branches and the relationship to cranial nerves and the brainstem. Fusiform aneurysms of the perimesencephalic segment of the PCA are a rare finding which does not favor direct clip occlusion or reconstruction. In such cases, proximal parent vessel occlusion is an option for aneurysm treatment. Extracranial-intracranial (EC-IC) bypass can be used to revascularize beyond the lesion when considering proximal occlusion...

BACKGROUND: Posterior circulation cerebral aneurysms are at higher risk of rupture and are more symptomatic than those in the anterior circulation. Existing treatments carry significant morbidity. Early reports of flow diversion for posterior circulation aneurysms have suggested high complication and low occlusion rates. OBJECTIVE: To report safety and efficacy of flow diversion with the pipeline embolization device (ev3, Medtronic Inc, Dublin, Ireland) for aneurysms located throughout the posterior circulation...

OBJECTIVE Flow diversion requires neointimal stent overgrowth to deliver aneurysm occlusion. The existing literature on aneurysm occlusion is limited by heterogeneous follow-up, variable antiplatelet regimens, noninvasive imaging modalities, and nonstandard occlusion assessment. Using a large, single-center cohort with low attrition and standardized antiplatelet tapering, the authors evaluated outcomes after flow diversion of anterior circulation aneurysms to identify predictors of occlusion and aneurysm persistence...

Flow diverting devices (FDDs) have revolutionized the treatment of morphologically complex intracranial aneurysms such as wide-necked, giant, or fusiform aneurysms. Although FDDs are extremely effective, they carry a small yet significant risk of intraprocedural complications. As the implementation of these devices increases, the ability to predict and rapidly treat complications, especially those that are iatrogenic or intraprocedural in nature, is becoming increasingly more necessary.Our objective in this paper is to provide a descriptive summary of the various types of intraprocedural complications that may occur during FDDs deployment and how they may best be treated...

BACKGROUND AND PURPOSE: Vertebrobasilar dolichoectatic and fusiform aneurysms (VBDAs) are known to have a poor natural history, with high rates of growth, rupture, and stroke. The purpose of this study was to identify hemodynamic characteristics that differ between VBDAs associated with growth, rupture, and stroke. MATERIALS AND METHODS: VBDAs with CT angiography or MR angiography followed longitudinally without treatment were studied. Unstable aneurysms were defined as those that grew or ruptured during follow-up...
