Optical coherence tomography for elucidation of flow-diversion phenomena: The concept of endothelized mural thrombus behind reversible in-stent stenosis in flow-diverters.

Interv Neuroradiol 2021 Mar 22:15910199211003432. Epub 2021 Mar 22.

Department of Neurosurgery, Advocate Aurora Health, Chicago, IL, USA.

Purpose: Flow-diverters have revolutionized the endovascular treatment of intracranial aneurysms, offering a durable solution to aneurysms with high recurrence rates after conventional stent-assisted coiling. Events that occur after treatment with flow-diversion, such as in-stent stenosis (ISS) are not well understood and require further assessment. After assessing an animal model with Optical Coherence Tomography (OCT), we propose a concept that could explain the mechanism causing reversible ISS after treatment of intracranial aneurysms with flow-diverters.

Novel Noncrossing Y-Stent Technique Using Tapered Proximal End of a Solitaire AB Stent for Coil Embolization of Wide-Neck Bifurcation Aneurysms.

J Korean Neurosurg Soc 2021 Jan 9;64(1):136-141. Epub 2020 Jul 9.

Department of Neurosurgery, Daejeon-Chungnam Regional Cerebrovascular Center, Chungnam National University Hospital, Chungnam National University Medical School, Daejeon, Korea.

The crossing Y-stent method is one of the indispensable techniques to achieve sufficient neck coverage during coil embolization of bifurcation aneurysms with a wide neck and/or branch incorporation. However, the inevitable hourglass-like expansion of the second stent at the crossing point can result in insufficient vessel wall apposition, reduced aneurysm neck coverage, delayed endothelialization, and subsequent higher risks of acute or delayed thrombosis. It also interferes with engagement of the microcatheter into the aneurysm after stent installation. Read More

Utility of Intravascular Ultrasound During Carotid Angioplasty and Stenting with Proximal Protection.

Cureus 2019 Jun 18;11(6):e4935. Epub 2019 Jun 18.

Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, Buffalo, USA.

Carotid artery stenting (CAS) is an established treatment for patients at high-risk for endarterectomy. Patients who undergo CAS have been shown to have periprocedural microembolic events on transcranial Doppler ultrasonography. Flow reversal is often applied in these situations to prevent distal emboli and concurrently allow blood to flush into the common carotid artery. Read More

Single-Center Case Series of Temporary Stent Assistance for Coiling of Acutely Ruptured Aneurysms.

World Neurosurg 2019 Mar 19;123:e766-e772. Epub 2018 Dec 19.

Department of Neurological Surgery, University of Florida, Gainesville, Florida, USA.

Background: Wide-necked intracranial aneurysms continue to pose a challenge for endovascular surgeons. Flow diversion and stent-assisted coiling are 2 techniques that have improved the ability to manage these lesions, but these require the use of dual antiplatelet therapy. In patients with aneurysmal subarachnoid hemorrhage, dual antiplatelet therapy is relatively contraindicated, and many surgeons prefer to use open techniques or balloon assistance for coiling, although at times the latter is not feasible.

Department of Neuroradiology, Southmead Hospital, North Bristol NHS Trust, Bristol, UK.

Background: The crucial role of thrombectomy in the management of emergent large vessel occlusive stroke is not disputed but there is a technical failure rate in a significant minority of patients whose outcomes are often poor. Our objective was to perform a systematic review and meta-analysis to assess the safety and efficacy of permanent self-expandable stent deployment as a bailout procedure in cases of failed anterior circulation thrombectomy.

Methods: Two independent reviewers searched the Pubmed (Medline) database for studies reporting outcomes following failed endovascular thrombectomy with subsequent rescue therapy employing self-expandable stents. Read More

Magnetic wires: A novel design for neuroendovascular coil retrieval.

Exp Ther Med 2018 Sep 23;16(3):2627-2632. Epub 2018 Jul 23.

Neurosurgery Department, The Second Xiangya Hospital of Central South University, Changsha, Hunan 410011, P.R. China.

The present study aimed to evaluate the operation, application and safety of a novel prototype device designed for the retrieval of a migrated coils, an intraprocedural complication of endovascular aneurysm treatment, compared with the widely used Solitaire AB stent retriever. The prototype retrieval device, referred to as magnetic wires, consisted of two microwires that were joined by a small magnetic ring near to the tips. To retrieve a coil, the wires are advanced through the dislodged coil one at a time and then capture the target coil in a chopstick-like manner, as their tips are attracted to the magnet. Read More

Permanent Deployment of the Solitaire FR™ Device in the Basilar Artery in an Acute Stroke Scenario.

Interv Neurol 2018 Feb 27;7(1-2):6-11. Epub 2017 Sep 27.

New York University Langone Medical Center, New York, New York, USA.

Background: Scarce reports exist of permanent deployment of Solitaire FR™ devices for arterial steno-occlusive disease as it is primarily indicated for temporary deployment for thrombectomy in large-vessel, anterior-circulation ischemic strokes. Even more scarce are reports describing permanent deployment of the Solitaire device for posterior circulation strokes.

What to do about fibrin rich 'tough clots'? Comparing the Solitaire stent retriever with a novel geometric clot extractor in an in vitro stroke model.

J Neurointerv Surg 2018 Sep 19;10(9):907-910. Epub 2018 Jan 19.

Jacobs Institute, Buffalo, New York, USA.

Background: Despite advances in revascularization tools for large vessel occlusion presenting as acute ischemic stroke, a significant subset of clots remain recalcitrant to current strategies. We assessed the effectiveness of a novel thrombectomy device that was specifically designed to retrieve resistant fibrin rich clots, the geometric clot extractor (GCE; Neuravi, Galway, Ireland), in an in vitro cerebrovascular occlusion stroke model.

Methods: After introducing fibrin rich clot analogues into the middle cerebral artery of the model, we compared the rates of recanalization between GCE and Solitaire flow restoration stent retriever (SR; Medtronic, Minneapolis, Minnesota, USA; control group) cases. Read More
