Association between type of intervention center and outcomes after endovascular treatment for acute ischemic stroke: Results from the MR CLEAN Registry.

Background: Endovascular treatment (EVT) for acute ischemic stroke (AIS) is performed in intervention centers that provide the full range of neuro(endo)vascular care (level 1) and centers that only perform EVT for AIS (level 2). We compared outcomes between these center types and assessed whether differences in outcomes could be explained by center volume (CV).

Patients And Methods: We analyzed patients included in the MR CLEAN Registry (2014-2018), a registry of all EVT-treated patients in the Netherlands.

Thrombus imaging characteristics within acute ischemic stroke: similarities and interdependence.

Background: The effects of thrombus imaging characteristics on procedural and clinical outcomes after ischemic stroke are increasingly being studied. These thrombus characteristics - for eg, size, location, and density - are commonly analyzed as separate entities. However, it is known that some of these thrombus characteristics are strongly related.

Cerebrospinal fluid volume improves prediction of malignant edema after endovascular treatment of stroke.

Background: The ratio of intracranial cerebrospinal fluid (CSF) volume to intracranial volume (ICV) has been identified as a potential predictor of malignant edema formation in patients with acute ischemic stroke.

Aims: We aimed to evaluate the added value of the CSF/ICV ratio in a model to predict malignant edema formation in patients who underwent endovascular treatment.

Methods: We included patients from the MR CLEAN Registry, a prospective national multicenter registry of patients who were treated with endovascular treatment between 2014 and 2017 because of acute ischemic stroke caused by large vessel occlusion.

The prognostic value of extracranial vascular characteristics on procedural duration and revascularization success in endovascularly treated acute ischemic stroke patients.

Introduction: Vascular anatomy might affect endovascular treatment success in acute ischemic stroke patients with large vessel occlusion. We investigated the prognostic value of extracranial vascular characteristics on procedural time and revascularization success in patients with large vessel occlusion in the anterior cerebral circulation.

Patients And Methods: We included 828 patients endovascularly treated within 6.

Malignant infarction after endovascular treatment: Incidence and prediction.

Background: Early prediction of malignant infarction may guide treatment decisions. For patients who received endovascular treatment, the risk of malignant infarction is unknown and risk factors are unrevealed.

Aims: The objective of this study is to estimate the incidence of malignant infarction after endovascular treatment in patients with an occlusion of the anterior circulation, to identify independent risk factors, and to establish a model for prediction.

Added value of intra-operative ultrasound to determine the resectability of locally advanced pancreatic cancer following FOLFIRINOX chemotherapy (IMAGE): a prospective multicenter study.

Background: Determining the resectability of locally advanced pancreatic cancer (LAPC) after FOLFIRINOX chemotherapy is challenging because CT-scans cannot reliably assess vascular involvement. This study evaluates the added value of intra-operative ultrasound (IOUS) in LAPC following FOLFIRINOX induction chemotherapy.

Methods: Prospective multicenter study in patients with LAPC who underwent explorative laparotomy with IOUS after FOLFIRINOX chemotherapy.

Impact of single phase CT angiography collateral status on functional outcome over time: results from the MR CLEAN Registry.

Background: Collateral status modified the effect of endovascular treatment (EVT) for stroke in several randomized trials. We assessed the association between collaterals and functional outcome in EVT treated patients and investigated if this association is time dependent.

Methods: We included consecutive patients from the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in The Netherlands (MR CLEAN) Registry (March 2014-June 2016) with an anterior circulation large vessel occlusion undergoing EVT.

Treatment of upper-extremity outflow thrombosis.

Approximately 10% of all cases of deep vein thrombosis (DVT) occur in the upper extremities. The most common secondary cause of upper-extremity DVT (UEDVT) is the presence of a venous catheter. Primary UEDVT is far less common and usually occurs in patients with anatomic abnormalities of the costoclavicular space causing compression of the subclavian vein, called venous thoracic outlet syndrome (VTOS).

[Effort thrombosis of the subclavian vein].

Three patients, 2 women aged 42 and 20 years and a 21-year-old man, presented with painful swelling of the upper extremity. The symptoms developed after activities involving repetitive, excessive use of the upper extremity. Duplex examination and venography showed thrombosis of the subclavian vein.
