Deep Learning for Needle Detection in a Cannulation Simulator [PDF]

open access: yesarXiv, 2021
Cannulation for hemodialysis is the act of inserting a needle into a surgically created vascular access (e.g., an arteriovenous fistula) for the purpose of dialysis. The main risk associated with cannulation is infiltration, the puncture of the wall of the vascular access after entry, which can cause medical complications.

Healing of venous ulcers secondary to an ankle arteriovenous fistula [PDF]

open access: yes, 2015
Venous ulcer as a complication of ankle arteriovenous fistula for hemodialysis is rarely reported. It poses a challenge between ulcer healing and fistula preservation.

Pulmonary arteriovenous fistula

open access: yesIndian Journal of Thoracic and Cardiovascular Surgery, 2021
A 30-year-old male patient presented with history of haemoptysis associated with cyanosis and clubbing. Chest computed tomography revealed a simple-type pulmonary arteriovenous fistula in the right middle lobe. Operative finding showed a bulging arteriovenous fistula covered with a thin layer of pleura. Right middle lobectomy was performed.

TiAVox: Time-aware Attenuation Voxels for Sparse-view 4D DSA Reconstruction [PDF]

open access: yesarXiv, 2023
Four-dimensional Digital Subtraction Angiography (4D DSA) plays a critical role in the diagnosis of many medical diseases, such as Arteriovenous Malformations (AVM) and Arteriovenous Fistulas (AVF). Despite its significant application value, the reconstruction of 4D DSA demands numerous views to effectively model the intricate vessels and radiocontrast

Fluid-structure interaction modelling and stabilisation of a patient-specific arteriovenous access fistula [PDF]

open access: yes, 2017
A patient-specific fluid-structure interaction (FSI) model of a phase-contrast magnetic resonance angiography (PC-MRA) imaged arteriovenous fistula is presented. The numerical model is developed and simulated using a commercial multiphysics simulation package where a semi-implicit FSI coupling scheme combines a finite volume method blood flow model and

U-Net-and-a-half: Convolutional network for biomedical image segmentation using multiple expert-driven annotations [PDF]

open access: yesarXiv, 2021
Development of deep learning systems for biomedical segmentation often requires access to expert-driven, manually annotated datasets. If more than a single expert is involved in the annotation of the same images, then the inter-expert agreement is not necessarily perfect, and no single expert annotation can precisely capture the so-called ground truth ...

Willingness to participate in a randomized trial comparing catheters to fistulas for vascular access in incident hemodialysis patients: an international survey of nephrologists [PDF]

open access: yes, 2016
BACKGROUND: Current guidelines favor fistulas over catheters as vascular access. Yet, the observational literature comparing fistulas to catheters has important limitations and biases that may be difficult to overcome in the absence of randomization ...

Date-Driven Approach for Identifying State of Hemodialysis Fistulas: Entropy-Complexity and Formal Concept Analysis [PDF]

open access: yesarXiv, 2023
The paper explores mathematical methods that differentiate regular and chaotic time series, specifically for identifying pathological fistulas. It proposes a noise-resistant method for classifying responding rows of normally and pathologically functioning fistulas.

Hemodynamic wall shear stress profiles influence the magnitude and pattern of stenosis in a pig AV fistula [PDF]

open access: yes, 2008
Venous stenosis is a significant problem in arteriovenous fistulae, likely due to anatomical configuration and wall shear stress profiles. To identify linkages between wall shear stress and the magnitude and pattern of vascular stenosis, we produced ...
