Thrombus perviousness is not associated with first-pass revascularization using stent retrievers.

Interv Neuroradiol 2019 Feb 4:1591019918825444. Epub 2019 Feb 4.

Joint Department of Medical Imaging, Toronto Western Hospital, Toronto, Canada.

Background And Purpose: Recent studies suggest that thrombus imaging characteristics such as Hounsfield unit (HU) and perviousness assessed on noncontrast computed tomography (NCCT) and CT angiography (CTA) can predict successful recanalization. We assessed whether these thrombus imaging characteristics could predict successful first-pass recanalization.

Methods: We retrospectively reviewed cases of mechanical thrombectomy over a three-year period in which patients received a multiphase CTA and were treated with a stent retriever on first pass. Read More

Current state of acute stroke care in Southeast Asian countries.

Interv Neuroradiol 2018 Nov 21:1591019918811804. Epub 2018 Nov 21.

8 National Neuroscience Institute, Singapore.

Acute stroke care systems in Southeast Asian countries are at various stages of development, with disparate treatment availability and practice in terms of intravenous thrombolysis and endovascular therapy. With the advent of successful endovascular therapy stroke trials over the past decade, the pressure to revise and advance acute stroke management has greatly intensified. Southeast Asian patients exhibit unique stroke features, such as increased susceptibility to intracranial atherosclerosis and higher prevalence of intracranial haemorrhage, likely secondary to modified vascular risk factors from differing dietary and lifestyle habits.

Department of Neurosurgery, St Marianna University School of Medicine, Kawasaki-shi, Japan.

The transfemoral approach is a common technique for carotid artery stenting. However, it has the risk of distal embolism when stenting for a stenosis of the proximal common carotid artery because of poor stability of the guiding catheter resulting in difficulty in setting the embolic protection device prior to stenting. We present a novel therapeutic approach and technique for the treatment of tandem carotid stenoses including the proximal common carotid artery. Read More

Persistent hypoglossal artery aneurysm: Case report and qualitative systematic review.

Interv Neuroradiol 2018 Nov 4:1591019918809087. Epub 2018 Nov 4.

Department of Neuroradiology, Royal Hallamshire Hospital, Sheffield, UK.

A persistent hypoglossal artery was first described in 1889 and is one of the more common anatomical variations arising from aberration in normal development. Endovascular coiling has been recognised as a robust treatment for acutely ruptured intracranial arterial aneurysms, although specific data regarding an aneurysm arising from a persistent hypoglossal artery is lacking due to the low incidence. Here we report both the oldest patient reported to be treated with a persistent hypoglossal artery-associated aneurysm and also explicitly report endovascular treatment of a persistent hypoglossal artery aneurysm arising at the posterior inferior communicating artery origin.

Endovascular intervention of acute ischemic stroke due to occlusion of fetal posterior cerebral artery.

Interv Neuroradiol 2018 Sep 19:1591019918801285. Epub 2018 Sep 19.

1 Department of Interventional Neuroradiology, University of Pittsburgh Medical Center - Hamot, Erie, USA.

A fetal posterior cerebral artery (FPCA) is an anatomic variant in which the posterior cerebral artery is an embryological derivative of the internal carotid artery. Although most cases of ischemic strokes in patients with FPCAs involve embolic infarcts, emergent large vessel occlusion of a FPCA is extremely rare. We present two cases of successful endovascular intervention for emergent occlusion of a FPCA, one of which is only the second reported case of a mechanical thrombectomy of a FPCA. Read More

1 Department of Neurosurgery, Yamagata Prefectural Central Hospital, Yamagata, Japan.

We describe a case of acute middle cerebral artery occlusion in a patient with ipsilateral internal carotid artery dysgenesis successfully treated with mechanical thrombectomy utilising a collateral pathway. During the procedure, a triaxial system using a balloon guiding catheter, flexible large lumen aspiration catheter and stent retriever was advanced from the left vertebral artery to the occluded left middle cerebral artery through the left posterior communicating artery. Because proximal aspiration from the balloon guiding catheter alone might have insufficient suction force due to the retrograde blood flow from large vascular communications (e. Read More
