Stroke thrombectomy beyond 24 hours improves functional outcome ... neuronewsinternational.com June 8, 2026, 6:22 a.m.
The LATE-MT randomized controlled trial demonstrates that mechanical thrombectomy can improve 90-day functional outcomes in anterior-circulation large vessel occlusion stroke patients presenting 24 to 72 hours after symptom onset, compared to standard medical care. However, the procedure carries significant risks, including increased mortality rates and symptomatic intracranial hemorrhage. While thrombectomy's benefits within earlier time windows have been well established, extending treatment beyond 24 hours shows promise for patients with slower disease progression. Despite functional improvements, clinicians must carefully weigh the therapeutic advantages against elevated adverse event rates when considering late thrombectomy interventions. These findings from the prospective, multicenter trial were presented at the 2026 European Stroke Organisation Conference, providing critical evidence for decision-making in extended-window stroke treatment protocols.

Surface modification of neurovascular stents: from bench to patient jnis.bmj.com June 2, 2026, 4:18 p.m.
Flow-diverting stents (FDs) for the treatment of cerebrovascular aneurysms are revolutionary. However, these devices require systemic dual antiplatelet therapy (DAPT) to reduce thromboembolic complications. Given the risk of ischemic complications as well as morbidity and contraindications associated with DAPT, demonstrating safety and efficacy for FDs either without DAPT or reducing the duration of DAPT is a priority. The former may be achieved by surface modifications that decrease device thrombogenicity, and the latter by using coatings that expedite endothelial growth. Biomimetics, commonly achieved by grafting hydrophilic and non-interacting polymers to surfaces, can mask the device surface with nature-derived coatings from circulating factors that normally activate coagulation and inflammation.
Assessing Predictive Factors for Thrombectomy Necessity in Acute Ischemic Stroke: Insights From the Direct to Angio Suite Protocol www.ahajournals.org June 2, 2026, 10:07 a.m.
Endovascular thrombectomy (EVT) has emerged as an effective treatment option. Unfortunately, interfacility transfers to thrombectomy-capable centers often delay treatment time. The direct to angio suite (DTA) pathway reduces interfacility transfer time by foregoing the emergency department at the thrombectomy-capable center and directing patients immediately to the angio suite. Up to 22% of patients transferred under the DTA pathway will not have a large vessel occlusion on cerebral angiography or will experience significant neurological improvement, obviating the need for EVT. This study evaluated predictive factors associated with EVT under the DTA protocol.

IA Thrombolysis After Thrombectomy: More Uncertainty www.medscape.com May 18, 2026, 9:45 a.m.
The strategy of administering intra-arterial (IA) thrombolysis immediately after thrombectomy in patients with acute ischemic stroke has come under renewed scrutiny after results from the TECNO trial showed no clear improvement in reperfusion rates with this approach.The idea of giving a dose of IA thrombolysis immediately after thrombectomy in patients with acute ischemic stroke has become more uncertain, with the results of a new trial showing no clear benefit on reperfusion rates using this approach.These results are in contrast to the previous CHOICE-2 trial, first presented earlier this year at the International Stroke Conference, and now published in JAMA. CHOICE-2 showed positive results in terms of good functional outcomes with an IA thrombolysis strategy, although this was dampened by an increased mortality rate.
Stent-assisted coiling and flow diverters effectively treat rare basilar artery cases www.news-medical.net May 18, 2026, 9:44 a.m.
Patients in the study underwent a range of minimally invasive procedures, including simple coiling, stent-assisted coiling, and flow diverters, devices designed to redirect blood flow away from the aneurysm. Stent-assisted coiling was the most common treatment, used in just over half of cases, while flow diverters were employed in nearly 30 %, particularly for more complex or larger aneurysms.The results were largely positive. At follow-up imaging, about 72 % of patients achieved complete aneurysm occlusion, meaning the aneurysm was fully sealed off, while nearly 19 % had near-complete occlusion. Clinically, about 89 % of patients had favorable outcomes, defined as minimal or no disability.
