Functional outcome in low-ASPECTS (0-5) acute ischemic stroke treated with mechanical thrombectomy: impact of laterality explored in a single-center study.

Background: There is no consensus regarding the influence of infarct laterality in patients with acute ischemic stroke due to anterior large vessel occlusion (AIS-LVO) treated with mechanical thrombectomy (MT), particularly in low-ASPECT (0-5) patients who were excluded from the initial MT studies and that participated in dedicated randomized-controlled trials that do not consider the side of the occlusion. We aimed to evaluate the role of infarct laterality on the clinical outcome in low-ASPECT AIS patients treated with MT.

Material And Methods: We retrospectively analyzed our institutional stroke database in our Thrombectomy-Capable Stroke Center (TCSC), including patient characteristics, procedural variables, and outcomes, between January 2015 and January 2022.

"National survey for preliminary evaluation of neuroradiological protocols in patients with infective endocarditis".

Objectives: The aim of this study was to identify imaging protocols in patients with infective endocarditis through a nationwide survey.

Methods: An electronic evolutionary survey was sent to interventional Neuroradiologists among neuroradiological centers, under the aegis of the Société Française de Neuroradiologie. Among 33 contacted centers, 25 completed the survey (21 universitary hospitals and 4 peripheric hospitals).

Portal phase alone is equivalent to multiphasic phase for CT diagnosis of acute non-traumatic pains in an emergency context.

Objectives: To evaluate radiological diagnosis concordance between a simplified and a multiphasic computed tomography (MCT) protocol for patients presenting acute non-traumatic abdominal pains (ANTAE).

Methods: During five consecutive months, all patients admitted in an emergency department for ANTAE were retrospectively included if they underwent MCT, including at least pre-contrast phase, late arterial phase (LAP), and portal venous phase (PVP). Clinical cases of suspected hemorrhagic conditions were secondarily excluded.

Evaluation of hepatic iron concentration heterogeneities using the MRI R2* mapping method.

Objective: To measure hepatic iron concentration (HIC) heterogeneities using a magnetic resonance R2* mapping method.

Patients And Methods: Ninety-four patients with suspected hepatic iron overload and 10 volunteers were included prospectively. A multi-echo R2* sequence with fat saturation and with three post-processing fitting methods (a single exponential decay model with or without truncation, SED and SEDt, and a constant offset model, COS) was compared to a signal intensity ratio method (SIR), considered as the reference.

Impact of the global outflow angle on recanalization after endovascular treatment of middle cerebral artery bifurcation aneurysms.

Background And Purpose: Intracranial aneurysm recanalization after endovascular treatment (EVT) remains a major problem. The goal of this study was to find new predictive factors of recanalization after EVT of middle cerebral artery (MCA) bifurcation aneurysms.

Methods: 96 MCA bifurcationaneurysms, ruptured or unruptured, treated by EVT between Septembre 2009 and December 2014, were retrospectively included.

Is bridging therapy still required in stroke due to carotid artery terminus occlusions?

Introduction: Studies comparing endovascular stroke treatment using mechanical thrombectomy (MT) with or without prior IV tissue plasminogen activator (tPa) have included only 30% of internal carotid artery terminus occlusions (ICA-O), a known predictor of recanalization failure with IV tPa.

Objective: To carry out a retrospective multicenter analysis of prospectively collected data of consecutive patients to investigate the impact of intravenous thrombolysis on ICA-O by comparing patients treated with MT alone or bridging therapy (BT).

Material And Methods: Patients with ICA-O treated with MT alone or BT were retrospectively examined and compared.

What is the pelvic lymph node normal size? Determination from normal MRI examinations.

Purpose: There are few previous reports on maximal pelvic lymph node sizes and no data on normal mesorectal nodes. Therefore, the aim of the study was to estimate the normal size of pelvic lymph nodes and to determine the upper limits of the normal range.

Materials And Methods: Pelvic magnetic resonance imaging (MRI) examinations were prospectively carried out using a Intera 1.

Predictive factors for complete response of chemoembolization with drug-eluting beads (DEB-TACE) for hepatocellular carcinoma.

Objectives: To identify clinical and imaging features associated with complete response (CR) to first session of transarterial chemoembolization (TACE) with drug-eluting beads (DEB) in patients with hepatocellular carcinoma.

Methods: In this prospective historical cohort, 172 patients with 315 tumours who received at least one DEB-TACE from 2007 to 2013 were studied. Imaging response was evaluated according to the modified Response Evaluation Criteria in Solid Tumours (mRECIST).

Assessment of normal left atrial appendage anatomy and function over gender and ages by dynamic cardiac CT.

Objectives: The aim of this study was to evaluate variations in anatomy and function according to age and gender using cardiac computed tomography (CT) in a large prospective cohort of healthy patients.

Background: The left atrial appendage (LAA) is considered the most frequent site of intracardiac thrombus formation. However, variations in normal in vivo anatomy and function according to age and gender remain largely unknown.

Autosomal dominant eccentric core disease caused by a heterozygous mutation in the MYH7 gene.

Background: Autosomal dominant (AD) central core disease (CCD) is a congenital myopathy characterised by the presence of cores in the muscle fibres which correspond to broad areas of myofibrils disorganisation, Z-line streaming and lack of mitochondria. Heterozygous mutations in the RYR1 gene were observed in the large majority of AD-CCD families; however, this gene was excluded in some of AD-CCD families.

Objective: To enlarge the genetic spectrum of AD-CCD demonstrating mutations in an additional gene.

A rare cause of stroke in young adults: occlusion of the middle cerebral artery by a meningioma postpartum.

Meningioma is the most common nonglial intracranial primary tumor. It is a slowly growing tumor and presents clinically by causing seizures along with neurological or neuropsychological deficit. However, acute presentation of meningioma is possible.
