Thrombosis of a basilar perforator aneurysm associated with pontine infarction in a patient with systemic lupus erythematosus.

Radiol Case Rep 2020 Jun 11;15(6):757-760. Epub 2020 Apr 11.

Department of Diagnostic Radiology, School of Medicine, Tohoku University, 1-1 Seiryo-cho Aoba-ku, Sendai, Japan.

Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple organ systems. Cerebral aneurysm formation is a rare central nervous system manifestation of SLE and tends to present as subarachnoid hemorrhage. Here, we report a 34-year-old woman with SLE complicated by a thrombosed aneurysm that had arose at the origin of a perforating artery, thereby causing obstruction of the artery and subsequent development of pontine infarction.

From Perviousness to Plaque Imaging in Acute Basilar Occlusions: The Impact of Underlying Stenosis and How to Detect It.

Stroke 2020 03 29;51(3):766-774. Epub 2020 Jan 29.

From the Department of Neuroradiology (M.T.B., D.P., C.M., B.F., C.Z., T.B.-B.), Klinikum Rechts der Isar, School of Medicine, Technical University of Munich, Germany.

Background and Purpose- Recent studies show that mechanical thrombectomy of acute basilar artery occlusions (BAO) results in high rates of successful recanalization and good outcomes, but predictors are not completely established yet. Varying occlusion types may benefit differently, and especially, an underlying basilar stenosis (BS) seems to have an impact. Aim of this study was to investigate angiographic and clinical differences in BAO subtypes and to test the potential of perviousness measures for a preinterventional identification of clinically relevant different occlusion types.

Diagnostic value of non-contrast brain computed tomography in the evaluation of acute cerebral venous thrombosis.

Sci Rep 2020 01 21;10(1):883. Epub 2020 Jan 21.

Department of Radiology, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran.

Acute cerebral vein thrombosis is usually seen as increased attenuation in brain non-contrast computed tomography. It is so helpful to define measurable parameters for subjective evaluation of sinus thrombosis in non-enhanced brain computed tomography, especially where advanced neuroimaging techniques are not available. The purpose of this study is to evaluate the diagnostic value of venobasilar attenuation ratio and venobasilar attenuation difference in the evaluation of acute cerebral venous sinuous thrombosis in non-enhanced brain CT scan.

Internal Carotid Artery to Posterior Cerebral Artery Bypass for Fusiform Basilar Artery Aneurysm: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2020 01;18(1):E1

Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona.

Fusiform dolichoectatic basilar trunk aneurysms pose an immense surgical challenge because of the extremely eloquent tissue at risk during the procedure and the complex management strategies required to relieve mass effect on the brainstem. The patient presented in this case experienced progressive brainstem deterioration with quadraparesis and multiple cranial neuropathies. The patient underwent a modified orbitozygomatic craniotomy for visualization, and an end-to-side anastomosis between a radial artery interposition graft and the posterior cerebral artery was performed, followed by an end-to-side anastomosis of the interposition graft to the intracranial internal carotid artery.

Direct puncture of the V3 segment of the vertebral artery in acute basilar artery stroke: an alternative approach in desperate circumstances.

BMJ Case Rep 2019 Aug 30;12(8). Epub 2019 Aug 30.

Interventional Neuroradiology, Royal Victoria Hospital, Belfast, UK.

A patient in his mid-40s presented with acute basilar artery thrombosis 7 hours postsymptom onset. Initial attempts to perform mechanical thrombectomy (MT) via the femoral and radial arterial approaches were unsuccessful as the left vertebral artery (VA) was occluded at its origin and the right VA terminated in the posterior inferior cerebellar artery territory, without contribution to the basilar system. MT was thus performed following ultrasound-guided direct arterial puncture of the left VA in its V3 segment, with antegrade advancement of a 4 French radial access sheath. Read More

Sección de Neurorradiología Diagnóstica y Terapéutica, Unidad de Gestión Clínica de Radiodiagnóstico, Hospital Universitario Reina Sofía, Córdoba, España.

Objectives: To determine the rate of recanalization, functional outcome at three months, and independent prognostic factors in patients with posterior circulation strokes treated with stent-retrievers and to compare these results with those of patients in an earlier series treated with "classical methods".

Material And Methods: This was a retrospective study of consecutive patients with posterior circulation strokes treated with stent-retrievers at our center between December 1, 2011 and May 1, 2018. The main outcome variables were the rate of recanalization according to the Thrombosis in Cerebral Infarction (TICI) scale and functional independence score 90 days after treatment according to the modified Rankin Scale (mRS).

Pipeline Embolization of an Infectious Basilar Artery Aneurysm in a 2-Year-Old Child: Case Report, Discussion of the Literature and Perioperative Considerations.

Oper Neurosurg (Hagerstown) 2019 11;17(5):E224-E228

Department of Neurology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania.

Background And Importance: Flow diversion of intracranial aneurysms has been rarely described in the pediatric population. Here we discuss the technical and perioperative complexities inherent in the flow diversion of an infectious basilar apex aneurysm in a 2-yr-old child with significant medical comorbidities.

Clinical Presentation: Following judicious oral administration of dual anti-platelet agents and intra-arterial administration of calcium channel blockers to treat vasospasm, standard endovascular procedures were used to place a flow diverting stent across the neck of a rapidly enlarging infectious aneurysm of the basilar apex.

Neurorestoration Center, Keck School of Medicine, University of Southern California, Los Angeles, California, USA; Department of Neurological Surgery, Keck School of Medicine, University of Southern California, Los Angeles, California, USA. Electronic address:

Large broad-based basilar artery (BA) apex aneurysms involving multiple arterial origins are complex lesions commonly not amenable to direct clipping or endovascular management. BA proximal (Hunterian) occlusion with extracranial-to-intracranial bypass is a supported strategy if 1 or both posterior communicating arteries are small. Hunterian ligation risks sudden aneurysm thrombosis and thromboembolism in the perforator-rich BA apex. Read More

Front Neurol 2018 16;9:858. Epub 2018 Oct 16.

Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, Beijing, China.

The diagnosis of intracranial arterial dissection (IAD) may be challenging and multimodal imaging techniques are often needed to confirm the diagnosis.
