Endovascular retrograde approach may be a better option for acute tandem occlusions stroke.
Conclusion For acute tandem occlusion stroke, favourable outcomes were better in patients undergoing retrograde therapy than in patients who received the anterograde approach. Future randomised trials are warranted to determine the optimal treatment. PMID: 30290710 [PubMed - as supplied by publisher]

Rate of periprocedural stroke in diagnostic cerebral angiograms comparing transradial versus transfemoral access
CONCLUSION: In our experience, using transradial access for diagnostic cerebral angiograms was associated with a low but not negligible incidence of periprocedural strokes. Patient anatomy should be evaluated prior to selection of vascular access. Patients should be made aware of a slightly higher periprocedural stroke risk with transradial access.PMID:36451543 | DOI:10.1177/15910199221142653

Percutaneous transluminal angioplasty and stenting for severe stenosis of the intracranial extradural internal carotid artery causing transient ischemic attack or minor stroke.
Authors: Ko JK, Choi CH, Cha SH, Choi BK, Cho WH, Kang TH, Sung SM, Cho HJ, Lee TH Abstract The purpose of this study is to assess the technical feasibility and clinical efficacy of percutaneous transluminal angioplasty and stenting (PTAS) for symptomatic stenosis of the intracranial extradural (petrous and cavernous) internal carotid artery (ICA).Review of medical records identified 26 consecutive patients who underwent PTAS using a balloon-expandable coronary stent (n = 15, 57.7%) or a Wingspan self-expandable stent (n = 11, 42.3%) for treatment of severe stenosis (>70%) involving the intracranial extr...

Improving mechanical thrombectomy time metrics in the angiography suite: Stroke cart, parallel workflows, and conscious sedation.
Conclusions Use of a stroke cart, parallel workflows by neurointerventionalists, technologists, and nursing staff, and use of conscious sedation may be useful to other institutions in efforts to improve procedural times. PMID: 29145742 [PubMed - as supplied by publisher]

Emergent extracranial internal carotid artery stenting and mechanical thrombectomy in acute ischaemic stroke.
CONCLUSIONS: Treatment of tandem extracranial ICA and intracranial occlusions in the setting of acute ischaemic stroke with extracranial carotid artery stenting followed by adjunctive intracranial mechanical thrombectomy is both safe and effective, but further evaluation of this treatment modality is necessary.

Mechanical thrombectomy in pediatric acute ischemic stroke: Clinical outcomes and literature review.
In this study, we report two cases of pediatric acute ischemic stroke treated with mechanical thrombectomy, both with good angiographic result (TICI 3) and clinical outcome (no neurological deficits at 90 days). In addition, we conducted a literature review of all previously reported cases describing the use of modern thrombectomy devices. Including our two cases, the aggregate rate of partial or complete vessel recanalization was 100% (22/22), and the aggregate rate of favorable clinical outcome was 91% (20/22). This preliminary evidence suggests that mechanical thrombectomy with modern devices may be a safe and effective...

Endovascular treatment outcomes using the Stroke Triage Education, Procedure Standardization, and Technology (STEPS-T) program.
Conclusions STEPS-T improved time-to-treat in patients undergoing mechanical thrombectomy for AIS. During the observation period, clinical outcomes significantly improved. PMID: 29119876 [PubMed - as supplied by publisher]

Successful recanalization using the Embolus Retriever with Interlinked Cage for acute stroke due to calcified cerebral emboli.
We describe a case of a mechanical thrombectomy with the Embolus Retriever with Interlinked Cage (ERIC) device in a patient with an acute ischemic stroke due to calcified cerebral emboli in the middle cerebral artery. The procedure was done after a failed recanalization attempt with manual aspiration thrombectomy. An 82-year-old woman presented to the emergency department with a sudden onset of right-sided weakness. A computed tomographic angiography showed left middle cerebral (M1 branch) calcified emboli. After the administration of an intravenous thrombolytic agent, the patient was transferred to the angiographic suite ...

Emergent carotid artery stenting in patients with acute ischemic stroke due to cervical internal carotid artery steno-occlusive lesion: Comparison of tandem intracranial occlusion and isolated cervical internal carotid artery occlusion.
CONCLUSIONS: Endovascular treatment in patients with acute ischemic stroke due to cervical internal carotid artery steno-occlusive lesion is a technically feasible and clinically effective intervention regardless of intracranial occlusion. Therefore, we recommend endovascular treatment regardless of the presence of concomitant intracranial artery occlusion for patients with acute ischemic stroke caused by cervical internal carotid artery steno-occlusive lesion.

Influence of carotid tortuosity on internal carotid artery access time in the treatment of acute ischemic stroke.
Conclusion Supraaortic vessel tortuosity significantly influences ICA-AT in mechanical thrombectomy for an acute large vessel. There furthermore was a trend for lower successful recanalization rates with increasing ICA-AT. PMID: 28944705 [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]

Initial experience with the novel EmboTrap II clot-retrieving device for the treatment of ischaemic stroke.
CONCLUSION: In our experience, mechanical thrombectomy with EmboTrap II is safe and effective. Reperfusion rate was comparable to that obtained with other stent retrievers. PMID: 30714502 [PubMed - as supplied by publisher]

Procedural approaches and angiographic signs predicting first-pass recanalization in patients treated with mechanical thrombectomy for acute ischaemic stroke.
CONCLUSIONS: The concurrence of the PBGC, the push and fluff technique, and the ACPS was associated with the highest rates of cFPE. Appropriate selection of the thrombectomy device and deployment technique may lead to better procedural outcomes. ACPS could be used to assess clot integration strategies in future trials.

Exophthalmos following mechanical thrombectomy for anterior circulation stroke: A retrospective study and review of literature.
CONCLUSIONS: Exophthalmos is not uncommon after mechanical thrombectomy (2.4%). The underlying mechanism is difficult to confirm, but it is most likely due to orbital ischemia from hypoperfusion or distal emboli. PMID: 32408783 [PubMed - as supplied by publisher]
