Novel Simplified Nasal Endoscopy Grading System for Hereditary Hemorrhagic Telangiectasia Patients

The Laryngoscope, EarlyView.
We validated a novel, simplified nasal endoscopy grading system for patients with Hereditary Hemorrhagic Telangiectasia (HHT). Our grading (mild, moderate, severe) demonstrated strong correlation with Epistaxis Severity Score (ESS) and Quality of Life (QoL), and showed substantial inter‐rater reliability (ICC = 0.8).

A case of pulmonary metastasis of giant cell tumor of bone presenting as pulmonary arteriovenous malformation

Journal of the Formosan Medical Association, 2015
Although giant-cell tumor (GCT) of the bone was originally classified as a benign tumor, metastasis has been reported. The radiographic features usually comprise parenchymal solitary or multiple nodules that are round-to-oval nodular opacities of ...

Dynamic pseudo‐continuous arterial spin labeling angiography using a 3D‐radial multi‐spoke spoiled gradient‐recalled sequence

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Accurate identification of arterial feeders and draining veins is critical for treatment decision‐making in patients with intracranial high‐flow vascular lesions. Currently available MRI sequences lack the temporal and spatial resolution needed for this task.

Few‐shot learning for highly accelerated 3D time‐of‐flight MRA reconstruction

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a deep learning‐based reconstruction method for highly accelerated 3D time‐of‐flight MRA (TOF‐MRA) that achieves high‐quality reconstruction with robust generalization using extremely limited acquired raw data, addressing the challenge of time‐consuming acquisition of high‐resolution, whole‐head angiograms.

Combined angiography and perfusion using radial imaging and arterial spin labeling with structural contrast

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a non‐contrast MRI method for the simultaneous acquisition of time‐resolved 3D angiographic, perfusion, and multi‐contrast T1‐weighted structural brain images in a single 6 min acquisition. Methods The proposed combined angiography and perfusion using radial imaging and arterial spin labeling with structural contrast (CAPRIA+

Intraoperative Bioprinting for Craniomaxillofacial Bone Reconstruction in Rats and Sheep

Small Science, EarlyView.
In rat and sheep calvarial models, a highly concentrated collagen‐based bioink (HC‐ink) is bioprinted and compared in combination with recombinant human bone morphogenetic protein‐2 (rhBMP‐2) or human adipose‐derived stem cells. Collectively, HC‐ink with the highest cell density and the addition of rhBMP‐2 contributes to improved new bone formation in ...

Management and outcome of a dog with hepatic arteriovenous malformation and extensive thrombosis of splanchnic vessels (Canis lupus)

Veterinary Record Case Reports, EarlyView.
Abstract This report describes the diagnosis, treatment and long‐term follow‐up of a dog with hepatic arteriovenous malformation and extensive thrombus of the splanchnic vessels. A 1‐year‐old, male, neutered golden retriever presented with haematochezia and ascites.

Splenic and pancreatic abscessation with vascular abnormalities in a dog

Veterinary Record Case Reports, EarlyView.
Abstract A 3‐year‐old male neutered Collie was presented with gastrointestinal signs, lethargy and weight loss, following a history of pancreatitis. Computed tomography revealed large, coalescing nodules in both the pancreas and spleen, and abdominal effusion. Analysis of effusion revealed degenerative neutrophils with intracellular bacteria.

Fatal rupture of pulmonary arteriovenous malformation in hereditary haemorrhagic telangiectasis and severe PAH

European Respiratory Review, 2009
29-yr-old patient with hereditary haemorrhagic telangiectasia was referred to the present authors’ centre with progressive exertional dyspnoea. Pulmonary arterial hypertension (PAH) was suspected on Doppler echocardiography and confirmed by right heart ...

Molecular regulation of arteriovenous endothelial cell specification [version 1; peer review: 2 approved]

F1000Research, 2019
The systemic circulation depends upon a highly organized, hierarchal blood vascular network that requires the successful specification of arterial and venous endothelial cells during development.
