Preclinical Efficacy and Safety Evaluation of a Novel Controlled‐Expansion ePTFE‐Covered TIPS Stent in a Swine Model

Portal Hypertension &Cirrhosis, EarlyView.
This preclinical study evaluated a novel controlled‐expansion expanded polytetrafluoroethylene (ePTFE)‐covered transjugular intrahepatic portosystemic shunt (TIPS) stent in 11 swine, demonstrating 100% technical success, excellent deployability, and durable 6‐month angiographic patency without thrombosis, migration, fracture, or device‐related toxicity.

Response to "Very late stent thrombosis after discontinuation of clopidogrel therapy" by Conroy MM, Bolsin SNC.

, 2009
The recent article by Barthwal and Herman highlights the problem of late stent thrombosis in a patient with a drug-eluting stent (DES) undergoing non-cardiac surgery (NCS).1 While the authors stated that clopidogrel therapy was ceased preoperatively and ...

Protosappanin A Alleviates Atherosclerosis by Regulating the MDM2/GPX4 Axis‐Mediated Endothelial Ferroptosis

Phytotherapy Research, EarlyView.
PTA alleviates atherosclerosis by regulating the MDM2/GPX4 axis‐mediated endothelial ferroptosis. ABSTRACT Endothelial ferroptosis is a crucial pathogenic driver of atherosclerosis (AS) progression. Protosappanin A (PTA), a bioactive compound from Caesalpinia sappan L., protects cardiovascular vessels by regulating ferroptosis.

PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

Small, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

Epiphora: A Structured Diagnostic Approach for the Otolaryngologist

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Introduction Epiphora, or excessive tearing, has historically been predominantly managed by ophthalmologists. However, as there is substantial overlap between ophthalmic and otolaryngologic anatomy and pathology that may contribute to epiphora, patients with this symptom often present to otolaryngologists as well.

An investigation into stent expansion using numerical and experimental techniques [PDF]

, 2009
Extensive finite element analyses have been carried out by researchers to investigate the difference in the mechanical loading induced in vessels stented with various different stent designs and the influence of this loading on restenosis outcome.

Interventional oncology in children: Where are we now?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

Association of Periprocedural Inflammatory Activation With Increased Risk for Early Coronary Stent Thrombosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Stent thrombosis is a rare but deleterious event. Routine coronary angiography with percutaneous coronary intervention (PCI) is often deferred in the presence of laboratory markers of acute inflammation to prevent complications.

Imaging of Abdominal Complications in Children With Acute Lymphoblastic Leukaemia

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy and remains one of the most common causes of cancer‐related death in children and adolescents. Five‐year overall survival rates now exceed 90% with current multidrug chemotherapeutic regimens. This improvement, coupled with the toxicity of chemotherapy, has led to the
