Article Synopsis
- Arterial ischemic stroke (AIS) in children, especially those with childhood leukemia, is a rare but serious condition that can lead to long-term disabilities, with a lack of established guidelines for treating it in pediatric patients.
- A case of a 13-year-old girl with acute lymphoblastic leukemia highlights successful mechanical thrombectomy using advanced devices, which allowed for effective recanalization of affected arteries.
- Despite emerging evidence supporting mechanical thrombectomy for children with AIS, definitive guidelines are still lacking, emphasizing the need for urgent, specialized care by a multidisciplinary team for optimal patient outcomes.*
Intracoronary administration of tenecteplase to prevent PCI-related myocardial infarction in patients with echo-attenuated coronary plaques: study protocol for a multicenter, prospective, randomized controlled trial.

Department of Cardiology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, China.
Background: Percutaneous coronary intervention (PCI)-related myocardial infarction (MI), especially the distal type associated with microvascular dysfunction, is not an uncommon complication of the procedure. Specific lesion features, the echo-attenuated plaques (EA) in particular, are well-established contributors to the pathogenesis of distal-type MI. These plaques are prone to disruption during PCI, leading to microvascular thrombosis and distal embolism.

Article Synopsis
- - This study investigated how coronary blood flow changes before and after a procedure called post-dilation in patients with STEMI undergoing PPCI, analyzing data from 419 patients treated between January 2019 and September 2023.
- - Among the 419 patients, 259 underwent post-dilation, which was more common in those with certain features like calcium plaque and larger stents; however, the rates of no-reflow and slow-flow were similar between the post-dilation and non-post-dilation groups.
- - Results showed post-dilation led to a significant increase in CTFC values and a notable rise in no-reflow/slow-flow rates, but performing post-dilation when CTFC was below 23.25 decreased
Demonstration of 1000 fps High-Speed Angiography (HSA) in Pre-Clinical In-vivo Rabbit Aneurysm Models During Flow-Diverter Treatment.

High Speed Angiography (HSA) at 1000 fps is a novel interventional-imaging technique that was previously used to visualize changes in vascular flow details before and after flow-diverter treatment of cerebral aneurysms in in-vitro 3D printed models. In this first pre-clinical work, we demonstrate the use of the HSA technique during flow-diverter treatment of in-vivo rabbit aneurysm models. An aneurysm was created in the right common carotid artery of each of two rabbits using previously published elastase aneurysm-creation methods.
