BACKGROUND: Flow-diverter stent (FDS) deployment can cause morphological and hemodynamic changes in the carotid siphon (CS), influencing the occlusion rate of aneurysms in this location. OBJECTIVE: To evaluate morphological changes to the CS after FDS deployment and their relationship with the rate of occlusion of intracranial aneurysms. METHODS: A cohort of 183 patients with CS aneurysms were treated by deployment of Pipeline® FDS (Medtronic Inc, Dublin, Ireland)...

BACKGROUND: The development of thromboembolism is one of the most common complications of neuroendovascular procedures. Although several small studies have deemed clopidogrel safe and effective in the prevention of intracranial stent thrombosis, ticagrelor has yet to be assessed in this setting. OBJECTIVE: The objective of this study was to retrospectively evaluate the safety and efficacy of ticagrelor in patients undergoing neuroendovascular procedures. METHODS: A retrospective review of patients receiving ticagrelor following neuroendovascular aneurysm repair...

Internal carotid artery (ICA) blister aneurysms are rare and challenging to successfully treat, using contemporary surgical or endovascular approaches, without partial or complete compromise of the parent vessel. We describe the use of a resheathable flow diverter, the Pipeline Flex Embolization Device (PFED) to perform stent-assisted coiling of a ruptured supraclinoid ICA blister aneurysm in a 56-year-old female who presented with a high-grade subarachnoid hemorrhage (SAH). The first PFED was deployed across the aneurysm neck to jail a microcatheter within the aneurysm dome, and then, two small coils were delivered into the aneurysm...

Background: Traumatic extracranial internal carotid artery (ICA) dissections are uncommon and can be difficult to treat. Thinning of adventitia and dilatation may occur following arterial dissection, thus resulting in a fusiform pseudoaneurysm, which can subsequently cause bleeding, expanding, or pulsatile hematoma. Currently, medical management with anticoagulation remains the first line of treatment and yields good outcomes in 75% of cases with a mortality rate of 3-4%. Endovascular intervention is indicated with failure of medical therapy, progressive enlargement of a traumatic pseudoaneurysm, acute flow-related infarcts due to vessel occlusion, or when anticoagulation is contraindicated due to risk of pseudoaneurysm rupture and hemorrhage...

Michael Karsy, Jian Guan, Andrea A Brock, Anubhav Amin, Min S Park
PURPOSE OF REVIEW: Stents and flow diverters have revolutionized the treatment of cerebrovascular disease. Guglielmi coils, flexible microcatheters, and first-generation intracranial stents, such as Neuroform (Stryker Neurovascular) and Enterprise stents (Codman/DePuy-Synthes), have paved the way for the development of the Pipeline Embolization Device (PED) (ev3/Covidien/Medtronic) and other endovascular approaches. RECENT FINDINGS: This review discusses the historical development of flow diverter technologies from the PED to similar devices, such as the Surpass stent (Stryker Neurovascular), the Flow-Redirection Endoluminal Device (FRED; MicroVention, Inc...

BACKGROUND: The pipeline embolization device (PED) is frequently used in the treatment of anterior circulation aneurysms, especially around the carotid siphon, with generally excellent results. However, treatment of posterior inferior cerebellar artery (PICA) aneurysms with flow diversion (FD) has not been specifically described or discussed. While there are reports of treating PICA aneurysms using placement of FD stents in the vertebral artery, there are no reports of treating these lesions by placement of flow diverting stents in the PICA vessel itself...

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...

INTRODUCTION: Non-saccular aneurysms of the posterior circulation are uncommon but highly dangerous lesions. Flow diverter stents have been demonstrated to be effective treatments of various anterior circulation aneurysms, particularly large and giant proximal internal carotid artery aneurysms. However, evidence regarding the treatment of non-saccular posterior circulation aneurysms with flow diverters is lacking. METHODS: A systematic literature review of the English language literature since 2007 was conducted using PubMed, MEDLINE, and Embase...

BACKGROUND: Intracavernous aneurysms constitute up to 9% of all intracranial aneurysms and 6% are infectious (IIA). First line therapy is a protracted antibiotic course, yet with failure, surgery and endovascular parent vessel sacrifice have been utilized. Reconstructive endovascular therapies have emerged for aneurysm control and may demonstrate a safer therapeutic alternative. OBJECTIVE: To present an IIA treated with a flow-diverting Pipeline stent (ev3 Neurovascular, Irvine, California)...

PURPOSE: Conventional coil embolization for large carotid cavernous aneurysms (CCAs) has limited utility due to its inability to prevent recurrences and reduce mass effect. Trapping of the parent artery may have a risk of ischemic complications due to intracranial perfusion disorders. We successfully treated 24 patients with large CCAs using a flow diverter (Pipeline™ embolic device: PED), and this report discusses the safety and efficacy of this method. MATERIALS AND METHODS: Twenty four patients (23 females, mean age 71...

BACKGROUND: Pre-aneurysmal internal carotid steno-occlusive disease resulting in cerebral intra-aneurysmal thrombosis and subsequent embolic infarction has not been previously described. CONCLUSION: Antithrombotic treatment for dissolution of the thrombus and pre-aneurysmal stent angioplasty followed by Pipeline embolization flow diverter placement through the aneurysm is a safe and feasible management option.

PURPOSE: Thromboembolic complications remain a limitation of flow diverting stents. We hypothesize that phosphorilcholine surface modified flow diverters (Pipeline Flex with Shield Technology, sPED) would have less acute thrombus formation on the device surface compared with the classic Pipeline Embolization device (cPED). METHODS: Elastase-induced aneurysms were created in 40 rabbits and randomly assigned to receive cPED or sPED devices with and without dual antiplatelet therapy (DAPT) (four groups, n=10/group)...

PURPOSE: Long-term data on aneurysm treatment with flow-diverting stents are still sparse, and follow-up protocols differ widely between institutions. We present long-term results, with a focus on the usefulness of contrast-enhanced MR angiography (ceMRA). MATERIALS AND METHODS: Interventions and follow-up imaging of patients with aneurysms treated by flow-diverting stents ("Pipeline," "Silk" and "FRED" models) without additional coiling were analyzed. All MRI scans included dedicated two-phase ceMRA...

We described a novel solution for a challenging case of double-layered LVIS Blue™ (LB) stent construct retraction into a large cavernous aneurysm. The double-layered LB stent construct was used as a flow diverter for treatment of a large cavernous aneurysm. Our solution comprised a balloon angioplasty and placement of balloon-mounted cardiac-stent construct through the side wall of the LB construct, with eventual placement of a Pipeline Flex inside of the final conduit.

BACKGROUND: The pipeline embolization device (PED; Medtronic, MN, USA) can sometimes herniate into the aneurysmal sac in an unexpected manner during or shortly after its deployment due to device foreshortening. In this report, we describe 2 endovascular techniques, which can be used to reposition a herniated PED construct into a more favorable alignment. SUMMARY: In a 67-year-old patient who had an intraprocedural herniation of a PED device into a giant cavernous aneurysm, a stent anchor technique was used to reverse the herniation, reorient the PED construct, and achieve successful flow diversion...
