1. {"_":"Mechanical Thrombectomy for Acute Vertebrobasilar Occlusion Associated with Pneumonia in a Child: A Case Report.","i":["Mycoplasma pneumoniae"]}
PMID:日期:2026-10-02Due to its rarity, high-quality evidence regarding mechanical thrombectomy for pediatric acute ischemic stroke remains limited. is a common cause of community-acquired pneumonia in children, and a recognized but uncommon cause of pediatric ischemic stroke. Reports describing large-vessel occlusion associated with infection are rare, and the role of mechanical thrombectomy in this setting remains unclear. A 5-year-old boy hospitalized for pneumonia developed a sudden onset of impaired consciousness and quadriplegia. Brain MRI demonstrated acute infarctions involving the brainstem and left cerebellar hemisphere, and MRA revealed vertebrobasilar artery occlusion. Mechanical thrombectomy using contact aspiration and a combined technique resulted in successful reperfusion (modified Thrombolysis in Cerebral Infarction score 2b) with retrieval of red thrombi. Subsequent investigations confirmed pneumonia, and an extensive evaluation failed to identify an alternative embolic source. These findings, together with the coagulation abnormalities observed during the acute phase, suggested that the ischemic stroke was most likely caused by thromboembolism associated with infection. Despite requiring decompressive craniectomy and intensive care, the patient achieved a favorable neurological outcome, with the modified Rankin Scale score improving from 3 at discharge to 1 at the 3-month follow-up. This case highlights the feasibility and potential efficacy of mechanical thrombectomy in selected pediatric patients with acute ischemic stroke, even in the setting of rare etiologies such as infection.

2. Endovascular Revascularization for Chronic Vertebral Artery Occlusion with Poor Collateral Circulation and a Large Perfusion Abnormality Identified by Automated Perfusion Imaging: A Case Report.
PMID:日期:2026-09-30Endovascular revascularization is increasingly used to treat symptomatic acute intracranial vertebral artery (ICVA) occlusion, with reported clinical benefit. In contrast, chronic total occlusion (CTO) is managed primarily with conservative therapy, and the indications for and efficacy of endovascular revascularization remain uncertain. A 74-year-old man with right vertebral artery (VA) occlusion and left VA stenosis was followed at our outpatient clinic. He presented with a 40-day history of dizziness and gait disturbance. MRI showed no new acute infarction, whereas MRA demonstrated bilateral VA occlusion. However, automated perfusion imaging (RAPID; iSchemaView, Golden, CO, USA) identified a large perfusion abnormality, leading to a diagnosis of symptomatic ICVA CTO. Urgent endovascular revascularization was performed. A small postoperative cerebellar infarction developed without new neurological deficits. Symptoms on admission improved with medical therapy and rehabilitation, and he was discharged home 14 days after the procedure; the perfusion abnormality had nearly resolved. At 2 months after hospital discharge, the patient remained asymptomatic, with no symptom recurrence. Endovascular revascularization for symptomatic ICVA CTO resulted in a favorable outcome. Automated perfusion imaging may help identify appropriate candidates for this treatment.

3. Perioperative Antiplatelet Therapy in the New Flow Diversion Era.
PMID:日期:2026-09-30Flow diverter (FD) technology has provided a new concept for the treatment of intracranial aneurysms: reconstruction of the parent artery by covering the neck with a braided mesh stent. It has enabled us to treat not only saccular aneurysms but also complex aneurysms that were previously considered difficult or impossible to treat. Despite its clinical impact, FD remains associated with thromboembolic and hemorrhagic complications, both of which are closely related to perioperative antiplatelet therapy. Dual antiplatelet therapy (DAPT), consisting of aspirin combined with a P2Y12 inhibitor, has traditionally been adopted as the standard strategy to reduce thromboembolic risk. However, the optimal regimen remains poorly defined, and substantial variability exists in clinical practice. Recent evidence suggests that the risk of thromboembolism is highest in the early perioperative period, while prolonged antiplatelet therapy may expose patients to unnecessary bleeding risks without clear additional benefits. In parallel, advances in platelet function testing, the availability of potent P2Y12 inhibitors, and the development of surface-modified FD devices are prompting reconsideration of the conventional paradigm of prolonged DAPT. This review provides a comprehensive synthesis of current evidence on perioperative antiplatelet therapy in the context of flow diversion and proposes a contemporary framework that emphasizes temporal risk stratification and individualized treatment strategies.

4. Single-Session Curative Transarterial Onyx Embolization of a Convexity Dural AVF with a Concomitant Pial AVF Sharing the Vein of Labbé: A Case Report and Literature Review.
PMID:日期:2026-09-26Pial arteriovenous fistula (PAVF) is a relatively rare and most commonly congenital intracranial arteriovenous shunt. We describe a presumed acquired PAVF coexisting with a convexity dural arteriovenous fistula (DAVF) that shares a common draining vein and discuss the potential pathophysiological mechanisms with reference to the literature. A 68-year-old man presented with slowed thought. Imaging demonstrated a convexity DAVF supplied by branches of the right external carotid artery and draining into the dorsal segment of the right vein of Labbé, as well as a PAVF supplied by cortical branches of the right middle cerebral artery with ventral drainage into the same vein. Under general anesthesia, transarterial Onyx (Medtronic, Minneapolis, MN, USA) embolization via the right middle meningeal artery achieved complete occlusion of both lesions by controlled Onyx penetration within the draining vein from the dorsal to the ventral segments. Complete obliteration was achieved when the Onyx reached the pial-feeder inflow site, and the procedure was completed without perioperative complications. Although rare, DAVF may coexist with a presumably acquired PAVF and share a common draining vein. Thorough preoperative delineation of the angioarchitecture is essential, because incomplete occlusion can precipitate delayed hemorrhage. When attempting a single-session treatment, meticulous control of Onyx reflux, avoiding inadvertent penetration into pial feeders, is critical to minimize the risk of cerebral infarction.

5. Telescope-Assisted Combined Thrombectomy (TACT-MeVO) for M2 Occlusion: A Technical Note and Initial Experience.
PMID:日期:2026-09-18This study aimed to describe telescope-assisted combined thrombectomy for medium vessel occlusion (TACT-MeVO) in patients with M2 occlusion and report our initial experience. We retrospectively reviewed 52 thrombectomy procedures in 51 patients with M2 occlusion between May 2015 and April 2026: 45 historical-protocol and 7 TACT-MeVO procedures. In TACT-MeVO, a small-bore aspiration catheter and stent retriever are withdrawn together into a large-bore M1 aspiration catheter. Outcomes and between-group P values were exploratory and descriptive; the study was not powered to test superiority. TACT-MeVO was first-line in all 7 procedures. Baseline CT-Alberta Stroke Program Early CT Score was numerically higher in the TACT-MeVO group but did not differ significantly (P = 0.069). Median puncture-to-recanalization/procedure-end time was 59 vs. 71 min (P = 0.014). One-pass completion was achieved in 6/7 (85.7%) vs. 23/45 procedures (51.1%; P = 0.117), and final modified Thrombolysis in Cerebral Infarction ≥2b in 7/7 (100%) vs. 39/45 procedures (86.7%; P = 0.580). Any subarachnoid hemorrhage occurred in 2/7 vs. 8/45 procedures (P = 0.608); both TACT-MeVO events were asymptomatic. Three-month modified Rankin Scale score 0-2 did not differ significantly (5/7 vs. 16/45; P = 0.104). A post hoc comparison with 29 procedures using conventional combined thrombectomy also showed a shorter procedural time (59 vs. 70 min; P = 0.004). TACT-MeVO was technically feasible in this initial 7-procedure experience. Comparative findings are descriptive; superiority or safety cannot be inferred because of the small sample, baseline imbalance, and historical comparator.

6. Stepwise Incisionless Percutaneous Flow-Control Treatment of a High-Flow Scalp Arteriovenous Fistula with a Large Superficial Venous Pouch: A Case Report.
PMID:日期:2026-09-18Scalp arteriovenous fistulas (AVFs) with multiple tortuous superficial feeders and a large venous pouch can require meticulous flow control during treatment. Open surgical excision may be associated with blood loss, wound-healing problems, and cosmetic concerns, whereas percutaneous liquid embolization of a high-flow superficial shunt carries a risk of nontarget migration and scalp necrosis. We report an incisionless, stepwise percutaneous flow-control strategy for such a lesion. A man in his 50s presented with a progressively enlarging, pulsatile right temporal mass, pulsatile tinnitus, and visual fatigue 30 years after head trauma. DSA revealed a high-flow scalp AVF supplied by the right superficial temporal artery (STA), the right occipital artery, and the contralateral STA, draining through a 2.5-cm superficial venous pouch; the lesion corresponded to Cho-Do type II and Yakes type IIb. We performed a stepwise percutaneous intervention. First, we injected epinephrine-containing lidocaine around the pouch to constrict distal feeding arteries. Second, we punctured the primary draining vein and deployed microcoils to establish a mechanical scaffold. Third, under circumferential compression, we sequentially injected 25% and 30% n-butyl cyanoacrylate-Lipiodol (Guerbet, Villepinte, France) mixtures via direct puncture to obliterate the posterior and anterior compartments. Finally, we occluded the residual STA feeder using ultrasound-guided percutaneous suture ligation. The patient experienced no ischemic cutaneous complications. DSA at 12 months confirmed complete AVF obliteration. In selected superficial scalp AVFs, combining pharmacological inflow reduction, direct-puncture coil scaffolding, circumferential compression, and ultrasound-guided percutaneous suture ligation may provide a less invasive alternative to open resection.

7. Reducing Door-to-Puncture Time with a Streamlined MRI-First Workflow for Endovascular Thrombectomy.
PMID:日期:2026-09-18Achieving door-to-puncture (D2P) times of less than 60 minutes remains challenging in endovascular thrombectomy (EVT), particularly within MRI-based triage systems. We evaluated whether implementation of an optimized workflow within an MRI-first triage strategy was associated with reduced D2P times. We conducted a retrospective, single-center, before-and-after observational study of consecutive patients who underwent EVT for acute ischemic stroke between September 2023 and August 2025. The optimized workflow, implemented on February 1, 2025, incorporated prehospital emergent large-vessel occlusion screening, early EVT team activation, advance preparation of MRI and angiography suites, omission of routine non-contrast CT, and parallel processing of patient evaluation and informed consent. The primary outcome was D2P time. Secondary outcomes included puncture-to-reperfusion (P2R) time, onset-to-reperfusion (O2R) time, 90-day functional outcomes, successful reperfusion, and symptomatic intracranial hemorrhage (sICH). A total of 177 patients were included: 124 in the previous-workflow group and 53 in the post-implementation group. Median D2P time decreased significantly from 76 minutes (interquartile range [IQR], 63-89) to 55 minutes (IQR, 45.5-75; p <0.001). P2R time was significantly longer in the post-implementation group (54 vs. 67 minutes; p = 0.047), whereas O2R time, successful reperfusion rates (Thrombolysis in Cerebral Infarction 2b-3), and sICH rates did not differ significantly between groups. The proportion of patients with good functional outcomes (modified Rankin Scale [mRS] score 0-2) was 30.7% in the previous-workflow group and 43.4% in the post-implementation group (p = 0.102). The proportion of patients with excellent outcomes (mRS score 0-1) was 16.9% and 32.1%, respectively (p = 0.029). Among the post-implementation cohort, 23 of 53 patients (43.4%) were managed under the optimized workflow; their median D2P time was 45 minutes. Implementation of an optimized workflow within an MRI-first imaging strategy was associated with a substantial reduction in D2P time without an apparent increase in procedural complications. Although clinical outcomes appeared to improve, these findings should be interpreted cautiously given baseline imbalances and the observational study design. These results support the feasibility of achieving sub-60-minute D2P times within MRI-first triage systems through structured workflow redesign.

8. Cervical Radiculopathy Caused by Epidural Venous Varix Associated with a Dural Arteriovenous Fistula in the Anterior Condylar Confluence: A Case Report.
PMID:日期:2026-09-12While degenerative disorders are the typical cause of cervical radiculopathy, vascular etiologies are exceedingly rare. Dural arteriovenous fistulas (dAVFs) in the anterior condylar confluence (ACC) generally manifest with cranial neuropathies or pulsatile tinnitus. This report presents a unique case of ACC dAVF producing an epidural venous varix and cervical radiculopathy and describes the staged therapeutic strategy leading to complete recovery. A man in his 70s presented with progressive right upper limb weakness. MRI detected an extradural mass compressing the C5 and C6 nerve roots, initially mimicking a tumor. DSA revealed an ACC dAVF with venous drainage into the cervical epidural venous plexus, forming a varix compressing the nerve roots. Through staged embolization (transarterial and transvenous), the fistula was successfully obliterated, resulting in partial neurological improvement. However, residual foraminal varices continued to cause motor weakness. After a short observation period, the patient underwent direct posterior foraminotomy with variceal coagulation. Postoperatively, motor strength steadily improved and eventually normalized, with sustained recovery during follow-up. This case highlights the rarity of cervical radiculopathy caused by an epidural venous varix secondary to ACC dAVF. Through endovascular embolization for shunt flow reduction, followed by surgical decompression, both the hemodynamic abnormality and mass effect were resolved.

9. Transarterial Onyx Embolization of a Hemorrhagic Tentorial Dural Arteriovenous Fistula via a Tortuous Occipital Artery: Technical Tips for Challenging Vascular Access.
PMID:日期:2026-09-09Tentorial dural arteriovenous fistulas (dAVFs) are rare, accounting for 4%-8% of intracranial dAVFs, and are associated with a high risk of hemorrhage. We report a case of a hemorrhagic tentorial dAVF located at the posterior falcotentorial junction, which was successfully treated by sequential transarterial embolization (TAE) despite severely tortuous feeder anatomy. A 67-year-old man presented with impaired consciousness due to cerebellar and intraventricular hemorrhage with obstructive hydrocephalus. DSA revealed a tentorial dAVF at the posterior falcotentorial junction (Cognard type IV, Borden type III) with venous ectasia draining into the inferior vermian vein. The fistula was predominantly supplied by the left occipital artery (OA) and the right posterior meningeal artery (PMA), with minor contributions from the right OA and the bilateral tentorial arteries. Sequential TAE was performed: the PMA feeder was first occluded with n-butyl cyanoacrylate, followed by Onyx-18 (Medtronic, Irvine, CA, USA) injection via the left OA. Navigation through the severely tortuous OA and its suboccipital segment required multiple technical innovations, including an S-shaped microguidewire tip (CHIKAI X010; Asahi Intecc, Aichi, Japan) and the use of a compliant balloon catheter (Scepter XC; Terumo, Tokyo, Japan) as an anchor to advance the intermediate catheter (Phenom Plus; Medtronic). Complete obliteration of the fistula was achieved. This case demonstrates that sequential TAE with technical innovations for vascular access can achieve curative treatment of tentorial dAVFs, even when feeder anatomy presents significant navigational challenges. The S-shaped wire technique and balloon-assisted intermediate catheter advancement may be applicable to other cases with tortuous vessel anatomy.

10. Bailout Guiding Catheter Exchange Using Medilizer: A Case Report.
PMID:日期:2026-09-03Medilizer (Medikit, Tokyo, Japan) is a distal anchoring exchange wire equipped with a soft, flexible self-expanding stent at the distal tip, designed to facilitate exchange maneuvers and device delivery. We report the use of the Medilizer for bailout guiding catheter exchange while preserving distal access. A 72-year-old man presented with progressive cerebral ischemia caused by acute right internal carotid artery (ICA) occlusion with contralateral chronic ICA occlusion. Percutaneous transluminal angioplasty (PTA) and Wingspan stent (Stryker Neurovascular, Fremont, CA, USA) placement in the right ICA were attempted under proximal balloon protection using a balloon-guiding catheter. After lesion crossing, the Medilizer was deployed from the proximal M2 to the proximal M1 segment. Cerebral angiography revealed severe cavernous ICA stenoses and multiple thrombi in the petrous ICA. During attempted PTA under proximal balloon protection, rupture of the balloon-guiding catheter necessitated an unexpected guiding catheter exchange. Because exchanging the entire system risked the loss of distal access, guiding catheter exchange was successfully attempted while maintaining the Medilizer in place using stepwise coaxial catheter advancement. Subsequent angioplasty and Wingspan stent placement achieved adequate revascularization without complications. Medilizer may provide an effective bailout option for unexpected guiding catheter exchange after lesion crossing by preserving distal access during neuroendovascular procedures.
