Hemorrhagic Transformation Rates following Contrast Media Administration in Patients Hospitalized with Ischemic Stroke ADULT BRAIN
CONCLUSIONS: Iso-osmolar contrast media was associated with a lower rate of hemorrhagic transformation compared with low-osmolar contrast media in patients with ischemic stroke.

Outcomes of young patients following mechanical thrombectomy for stroke: A systematic review and meta-analysis
CONCLUSIONS: Following mechanical thrombectomy for AIS, patients aged 18-65 years achieved relatively high rates of functional independence and successful reperfusion and low rates of mortality and sICH.Clinical Perspective In this systematic review and meta-analysis of eight studies, we examined outcomes in young stroke patients, aged 18-65 years old, following mechanical thrombectomy for acute ischemic stroke. We found that young patients achieved high rates of functional independence, high rates of successful reperfusion, and low rates of mortality and symptomatic intracerebral hemorrhage.While there have been several p...

Multi-center prediction of hemorrhagic transformation in acute ischemic stroke using permeability imaging features
Abstract: Permeability images derived from magnetic resonance (MR) perfusion images are sensitive to blood–brain barrier derangement of the brain tissue and have been shown to correlate with subsequent development of hemorrhagic transformation (HT) in acute ischemic stroke. This paper presents a multi-center retrospective study that evaluates the predictive power in terms of HT of six permeability MRI measures including contrast slope (CS), final contrast (FC), maximum peak bolus concentration (MPB), peak bolus area (PB), relative recirculation (rR), and percentage recovery (%R). Dynamic T2*-weighted perfusion MR images ...

Efficacy of Peripheral Interventional Radiologists Performing Endovascular Stroke Therapy Guided by CT Perfusion Triage of Patients
Conclusions: Peripheral interventional radiologists who use CT perfusion imaging for patient triage can have good neurologic outcomes and provide sustainable, safe, and complete around-the-clock coverage for endovascular stroke treatment.

Complications of Endovascular Treatment for Acute Stroke in the SWIFT Trial with Solitaire and Merci Devices EVIDENCE-BASED MEDICINE LEVEL 2
CONCLUSIONS: Understanding of procedural complications is important for treatment of patients with stroke after endovascular treatment. We observed fewer endovascular complications with the Solitaire FR device treatment compared with Merci device treatment, particularly symptomatic cerebral hemorrhage.

Periprocedural complications in endovascular stroke treatment.
We present the digital subtraction angiography and computed tomography imaging findings related to these complications in a study of 56 stroke patients, as they relate to previous findings in the literature. PMID: 26529228 [PubMed - as supplied by publisher]

Favorable Bridging Therapy Based on DWI-FLAIR Mismatch in Patients with Unclear-Onset Stroke INTERVENTIONAL
CONCLUSIONS: The study demonstrates the safety and good clinical outcome of acute recanalization therapy in patients with acute stroke in the anterior circulation and an unknown time of onset and a DWI/FLAIR mismatch on imaging. Moreover, bridging therapy versus intravenous thrombolysis alone was independently associated with favorable outcome at 3 months.

Stenting of the cervical internal carotid artery in acute stroke management: The Karolinska experience.
Conclusions Our single-centre retrospective analysis of emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy demonstrated high technical success, reasonable clinical outcomes and acceptable rates of symptomatic intracranial haemorrhage in carefully chosen patients which are triaged interdisciplinary based on clinical and computed tomography imaging criteria. This warrants further study in a randomised prospective trial. PMID: 28304205 [PubMed - in process]
