Mechanism of Action and Biology of Flow Diverters in the Treatment of Intracranial Aneurysms

Mechanism of Action and Biology of Flow Diverters in the Treatment of Intracranial Aneurysms | Neurovascular Intervention | Scoop.it

Flow diverters have drastically changed the landscape of intracranial aneurysm treatment and are now considered first-line therapy for select lesions. Their mechanism of action relies on intrinsic alteration in hemodynamic parameters, both at the parent artery and within the aneurysm sac. Moreover, the device struts act as a nidus for endothelial cell growth across the aneurysm neck ultimately leading to aneurysm exclusion from the circulation. In silico computational analyses and investigations in preclinical animal models have provided valuable insights into the underlying biological basis for flow diverter therapy.

First-in-human trial of a self-expandable, temporary dilation system for intracranial atherosclerotic disease in patients presenting with acute ischemic stroke

First-in-human trial of a self-expandable, temporary dilation system for intracranial atherosclerotic disease in patients presenting with acute ischemic stroke | Neurovascular Intervention | Scoop.it

Intracranial atherosclerotic disease (ICAD) significantly contributes to ischemic stroke, especially among Asian populations. Large vessel occlusion (LVO) due to underlying ICAD accounts for 15–35% of acute ischemic stroke cases requiring endovascular therapy. However, the successful recanalization rate of ICAD-related LVO remains lower. The TG dilator is a self-expandable device, temporarily dilating ICAD-related blocked blood vessels.

Thrombectomy Choice in Basilar Stroke May Hinge on Clot Type

Thrombectomy Choice in Basilar Stroke May Hinge on Clot Type | Neurovascular Intervention | Scoop.it

In stroke due to basilar artery occlusion, the best technique to use for thrombectomy appears to depend on the underlying etiology of the clot, a new trial suggested. The Chinese ANGEL-COAST randomized trial compared two different techniques used for endovascular thrombectomy — either contact aspiration or stent retriever — in patients with basilar artery occlusion stroke. Results showed that using contact aspiration on the first attempt at clot removal achieved higher initial reperfusion rates without increasing the risk for symptomatic intracerebral hemorrhage or periprocedural complications.

Managing thrombosis risk in flow diversion: A review of antiplatelet approaches

Managing thrombosis risk in flow diversion: A review of antiplatelet approaches | Neurovascular Intervention | Scoop.it

Flow diversion is a transformative approach in neurointerventional surgery for intracranial aneurysms that relies heavily on effective antiplatelet therapy. The ideal approach, including the timing of treatment, the use of dual antiplatelet therapy (DAPT), and the number of flow-diverter devices to use, remains unknown. DAPT, which combines aspirin with a thienopyridine like clopidogrel, prasugrel, or ticagrelor, is the standard regimen, balancing thromboembolic protection and hemorrhagic risk. The variable response to clopidogrel, influenced by genetic polymorphisms, necessitates personalized treatment strategies. Alternatives like prasugrel and ticagrelor provide superior efficacy in specific scenarios but require careful consideration of bleeding risks and costs.

Variability patterns in dual antiplatelet therapy following endovascular repair of intracranial aneurysms

Variability patterns in dual antiplatelet therapy following endovascular repair of intracranial aneurysms | Neurovascular Intervention | Scoop.it

Despite growing evidence supporting the success of DAPT in reducing thromboembolic events, the lack of consensus on optimal regimens, doses, and duration is evident. Factors contributing to this variability include genetic polymorphisms affecting treatment response and ongoing debates regarding the clinical significance of hemorrhagic complications associated with DAPT.

Clear Benefit of Thrombectomy in Large-Core Stroke

Clear Benefit of Thrombectomy in Large-Core Stroke | Neurovascular Intervention | Scoop.it

A new individual patient-level data meta-analysis has shown “overwhelming benefit” of endovascular thrombectomy (EVT) in a wide spectrum of patients with large-core strokes. The ATLAS meta-analysis showed consistent improvements in functional independence and independent ambulation and reduced mortality with EVT compared with best medical management alone. The treatment benefit of EVT was maintained across key clinical and imaging subgroups, regardless of age, sex, clinical severity, time to treatment, stroke size, and mismatch profile.

Contact aspiration’s first-pass benefits seemingly “offset” by inferior final recanalisation versus stent retrievers in basilar occlusion stroke

Contact aspiration’s first-pass benefits seemingly “offset” by inferior final recanalisation versus stent retrievers in basilar occlusion stroke | Neurovascular Intervention | Scoop.it

In patients with vertebrobasilar artery occlusion (VBAO) stroke undergoing mechanical thrombectomy, first-line contact aspiration appears to produce a greater first-pass effect (FPE) compared to a stent retriever-only approach. However, stent retriever-first techniques may yield better final reperfusion rates, resulting in no significant difference in overall clinical outcomes between the two. As such, researchers believe that technique selection based on the underlying occlusion aetiology may be critical, and further analyses are warranted to clarify this relationship.

Management of Acute Ischemic Stroke

Management of Acute Ischemic Stroke | Neurovascular Intervention | Scoop.it

Stroke mortality has been declining over the past 6 decades, and as a result, stroke has fallen from the second to the fifth leading cause of death in the United States. This trend may follow recent advances in the management of stroke, which highlight the importance of early recognition and early revascularization. Recent studies have shown that early recognition, emergency interventional treatment of acute ischemic stroke, and treatment in dedicated stroke centers can significantly reduce stroke-related morbidity and mortality. However, stroke remains the second leading cause of death worldwide and the number one cause for acquired long-term disability, resulting in a global annual economic burden.

Overall, considerably more success has been achieved in reducing the thrombogenicity of bio-artificial surfaces than in controlling complement activation: For example, surfaces coated with different forms of heparin or PEG are associated with low or negligible activation of coagulation and subsequent platelet loss. Thus, there are numerous surfaces that have low thrombogenicity available that still bear substantial complement-activating capacity. Some of these materials will no doubt be a

The Potential Therapeutic Effects of Tadalafil on the Endothelium in a Subarachnoid Hemorrhage Animal Model: Insights from Immunohistochemical Staining

Tadalafil, which has the longest half-life among PDE-5 inhibitors, does not prevent endothelial apoptosis as much as nimodipine, but it still prevents smooth muscle cell proliferation in the tunica media, restores damaged endothelial integrity, increases cerebral blood flow, and is thought to have various neuroprotective functions through the PI3K/AKT/eNOS signaling pathway. We believe that more in-depth research on tadalafil in the future will prove the therapeutic potential of this drug for DCI.

While clot composition does not significantly affect the success of First Pass Recanalization (FPR), it is significantly associated with the risk of intracranial hemorrhage. This underscores the potential clinical relevance of clot histology in predicting post-thrombectomy outcomes, beyond the well-established importance of FPR itself. Future studies with larger and more diverse patient cohorts are warranted to further elucidate these associations and optimize treatment strategies.

Antiplatelet therapy is key to reducing local thrombotic complications and systemic ischaemic events among patients undergoing percutaneous coronary interventions (PCI), but it is inevitably associated with increased bleeding. The continuous refinement in stent technologies, together with the high incidence of ischaemic recurrences after PCI and the understanding of prognostic implications associated with bleeding, have led to a substantial evolution in antiplatelet treatment regimens over the past decades.
