MRI Quantitative T2* Mapping to Predict Dominant Composition of In Vitro Thrombus ADULT BRAIN
CONCLUSIONS: MR imaging quantitative T2* mapping can reliably identify the thrombus red blood cell content in vitro. This fast, easy-to-use sequence could be implemented in routine practice to predict stroke etiology and adapt devices or techniques for endovascular treatment of acute ischemic stroke.

Safety of Intra-Arterial Tirofiban Administration in Ischemic Stroke Patients after Unsuccessful Mechanical Thrombectomy
ConclusionsLow-dose IA tirofiban administration may be relatively safe in patients with ischemic stroke after unsuccessful recanalization.

MRI findings in patients with acute coronary syndrome and unobstructed coronary arteries.
CONCLUSION: Our study emphasizes the diagnostic utility of timely MRI in patients with ACS and unobstructed coronary arteries. We found a high prevalence of TTS patients, who had poorer outcomes compared with patients with a final diagnosis of AMI or myocarditis. PMID: 30582569 [PubMed - as supplied by publisher]

Gadolinium to the rescue for mechanical thrombectomy in acute ischemic stroke.
CONCLUSION: Gadolinium-based contrast agents could be effective alternatives for cerebral DSA in patients undergoing mechanical thrombectomy for AIS who have a history of anaphylactic reaction to ICs. PMID: 30567455 [PubMed - as supplied by publisher]

Endovascular Stroke Therapy with a Novel 6-French Aspiration Catheter
ConclusionEndovascular stroke therapy using the AXS Catalyst catheter seems safe and effective, with similar performance than other reperfusion catheters.

Paradoxical Thromboembolic Ischemic Stroke and Pulmonary Embolism after Uterine Fibroid Embolization
We report a case of acute paradoxical ischemic stroke after UFE in a patient with an inherited thrombophilia, who was successfully treated with endovascular clot retrieval. Institutional review board approval was not required.

A back and forth manual aspiration technique using a SOFIA Plus catheter for acute ischemic stroke: technical note
ConclusionThis modified technique with back and forth movements of the SOFIA Plus catheter over the thrombus during aspiration may facilitate thrombectomy in AIS. However, further studies in larger groups are necessary to elucidate its efficacy and to compare with current techniques.

Acute administration of tirofiban versus aspirin in emergent carotid artery stenting.
CONCLUSIONS: Tirofiban and aspirin demonstrated similar efficacy and safety in thrombolyzed stroke patients who underwent eCAS in our cohort. Intravenous tirofiban with its short half-life might represent an alternative to aspirin in select patients. PMID: 30394839 [PubMed - as supplied by publisher]

Utility of Hounsfield unit and hematocrit values in the diagnosis of acute venous sinus thrombosis in unenhanced brain CTs in the pediatric population
ConclusionOptimal cutoff values of 58 HU and HU:Hct ratios of 1.4 lead to sensitivities of 100% in diagnosing CVST.

Reperfusion Changes After  Stroke and Practical Approaches for Neuroprotection
Reperfusion is the first line of care in a growing number of eligible acute ischemic stroke patients. Early reperfusion with thrombolytic drugs and endovascular mechanical devices is associated with improved outcome and lower mortality rates compared with natural history. Reperfusion is not without risk, however, and may result in reperfusion injury, which manifests in hemorrhagic transformation, brain edema, infarct progression, and neurologic worsening. In this article, the functional and structural changes and underlying molecular mechanisms of ischemia and reperfusion are reviewed. The pathways that lead to reperfusion...

Thrombus Permeability on Dynamic CTA Predicts Good Outcome after Reperfusion Therapy INTERVENTIONAL
CONCLUSIONS: Thrombus permeability assessed on dynamic CTA could be a better predictor of outcome after reperfusion therapy than that assessed on conventional single-phase CTA.

A direct aspiration first pass technique with the new ARC catheter for thrombectomy of large vessel occlusion strokes: A multicenter study.
Conclusions In the present study, the ARC catheter allowed a 98% successful reperfusion rate. The complication rate was in line with those of previous a direct aspiration first pass technique publications. PMID: 30290720 [PubMed - as supplied by publisher]

Endovascular aspiration of a symptomatic free-floating common carotid artery thrombus
AbstractFree-floating thrombi of the common carotid artery (CCA) are a very rare cause of ischemic stroke. To date, only a few reports have been described in the academic literature. Revascularization is indicated due to the risk of thromboembolic disease and hemodynamic-related stroke syndromes. Medical treatment typically includes anticoagulation and, in some circumstances, open surgical thrombectomy is an additional option. Although rarely described in the literature, endovascular thrombectomy is a viable treatment alternative in these patients.

Combined aspiration thrombectomy and continuous intrasinus thrombolysis for cerebral venous sinus thrombosis: technical note and case series
We report a retrospective study of angiographic and clinical outcome of six consecutive patients treated with this approach. Endovascular aspiration thrombectomy with large bore catheters followed by continuous local thrombolytic infusion appeared to be a safe and effective salvage treatment for selected patients with cerebral dural venous sinus thrombosis refractory to medical treatment.
