Evaluation of the yield of post-clipping angiography and nationwide current practice.

Acta Neurochir (Wien) 2019 Feb 19. Epub 2019 Feb 19.

Department of Neurosurgery, University Medical Center Utrecht, Internal Postage: G03.124, PO-box 85500, 3584 CX, Utrecht, The Netherlands.

Background: Surgical treatment of intracranial saccular aneurysms aims to prevent (re)hemorrhage by complete occlusion of the aneurysmal lumen. It is unclear whether routine postoperative imaging, to assess aneurysmal occlusion, is necessary since intraoperative assessment by the neurosurgeon may be sufficient. We assessed routine clinical protocols for post-clipping imaging in the Netherlands and determined whether intraoperative assessment of aneurysm clippings sufficiently predicts aneurysm residuals.

Indocyanine Green and Contrast-enhanced Ultrasound videoangiography: a synergistic approach for real time verification of distal revascularization and aneurysm occlusion in a complex distal middle cerebral artery aneurysm.

World Neurosurg 2019 Feb 15. Epub 2019 Feb 15.

Oncological Neurosurgery Unit, Department of Neurosurgery, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy; Department of Pathophysiology and Transplantation, Università degli Studi di Milano, Milan, Italy.

Background: Distal outflow occlusion and extracranial-intracranial bypass represent a possible option for the surgical management of complex middle cerebral artery (MCA) aneurysm. A limitation of distal clipping strategy combined to bypass relies on the difficulties in predicting intraoperatively the good blood flow supply to the brain territory distal to the aneurysm and the extent and speed of aneurysmal thrombosis.

Methods: The authors presented an innovative approach in which Contrast-enhanced US (CEUS) and indocyanine green video-angiography (ICG-VA) have been synergistically used to study the effect of distal clipping on the aneurysm flow and the parenchymal blood flow after the bypass. Read More

Basilar Apex Aneurysms in the Setting of Carotid Artery Stenosis: Case Series and Angiographic Anatomic Study.

Curr Neurovasc Res 2019 Jan 29. Epub 2019 Jan 29.

Departments of Neurological Surgery, Loyola University Stritch School of Medicine, Maywood, IL. United States.

Background: Intracranial aneurysms (IAs) are life-threatening lesions known within the literature to be found incidentally during routine angiographic workup for carotid artery stenosis (CAS). As IAs are associated with vascular shear stress, it is reasonable to expect that altered flow demands within the anterior circulation, such as with CAS, increase compensatory flow demands via the Circle of Willis (COW) and may induce similar stress at the basilar apex.

Objective: We present a series of nine unruptured basilar apex aneurysms (BAA) with CAS and a comparative radiographic analysis to BAA without CAS. Read More

Ultra-high-resolution subtraction CT angiography in the follow-up of treated intracranial aneurysms.

Insights Imaging 2019 Jan 28;10(1). Epub 2019 Jan 28.

Department of Radiology and Nuclear Medicine, Radboud University Medical Center, Geert Grooteplein 10, P/O Box 9101, 6500 HB, Nijmegen, The Netherlands.

In subtraction CT angiography (CTA), a non-contrast CT acquisition is subtracted from a contrast-enhanced CTA acquisition. Subtraction CTA can be applied in the detection, classification, and follow-up of intracranial aneurysms and is advantageous over conventional angiography because of its non-invasive nature, shorter examination time, and lower costs. Recently, an ultra-high-resolution CT scanner has been introduced in clinical practice offering an in-plane spatial resolution of up to 0. Read More

Braided stents and their impact in intracranial aneurysm treatment for distal locations: from flow diverters to low profile stents.

Expert Rev Med Devices 2019 Jan 28:1-15. Epub 2019 Jan 28.

a Department of Neuroradiology and Endovascular Treatment , Jean-Minjoz University Hospital , Besancon , France.

Introduction: Intracranial aneurysms in distal locations are sometimes difficult to treat due to their branching locations and the presence of blister-like or very wide-necked aneurysms. Braided intracranial stents, including flow diverters (FDs) and low-profile braided intracranial stents (LPBSs) may provide additional advantages, due to their flow-diverting properties. Areas covered: The use of FDs in off-label, distal intracranial locations has been increasing with promising outcomes and has given rise to the LPBS, which has less flow-diverting properties, allowing for easier use in distal branching sites through 0.

FIVHeMA: Intraventricular fibrinolysis versus external ventricular drainage alone in aneurysmal subarachnoid hemorrhage: A randomized controlled trial.

Neurochirurgie 2019 Feb 9;65(1):14-19. Epub 2019 Jan 9.

Department of neurosurgery, CHU de Caen, 14000 Caen, France; Inserm U1237 'physiopathology & imaging of neurological disorders', university of Caen Normandy, 14000 Caen, 14000, France; Université Caen Normandie, Medical School, 14000 Caen, France.

Introduction: Aneurysmal subarachnoid hemorrhage (SAH) is a devastating form of stroke, which often causes acute hydrocephalus requiring the insertion of an external ventricular drain (EVD). A major complication of aneurysmal SAH is delayed cerebral ischemia (DCI). As DCI is linked to the presence of blood within the subarachnoid space, it has been hypothesized that removing this blood may decrease the risk of DCI. Read More

Microsurgical Clipping of Low-Riding Basilar Bifurcation Aneurysm.

World Neurosurg 2018 Dec 31. Epub 2018 Dec 31.

Department of Neurosurgery, Universidade Federal de Sao Paulo, São Paulo-SP, Brazil. Postal adress: Doutor Diogo de Faria, 775, conjunto 91, 04037-002, São Paulo-SP, Brazil.

Basilar bifurcation is a challenging site for aneurysm clipping. Anatomical factors such as size and projection of the aneurysm, distance between the aneurysm neck and the dorsum sellae, and location of the basilar bifurcation contribute to surgical complexity. Endovascular treatment has been used more frequently than microsurgical clipping, especially for posterior circulation lesions. Read More
