Outcomes of the Paramedian Forehead Flap for Nasal Reconstruction: Systematic Review and Meta‐Analysis

The Laryngoscope, EarlyView.
ABSTRACT Objective(s) Paramedian forehead flap (PMFF) reconstruction remains the gold standard for complex nasal defects, yet outcomes have not been comprehensively synthesized. We aimed to define flap survival, complication profiles, and reconstructive patterns through the largest systematic review and meta‐analysis of PMFFs to date.

Does routine use of indocyanine green fluorescence angiography prevent anastomotic leaks? A retrospective cohort analysis.

, 2019
BACKGROUND: Insufficient perfusion to anastomoses in colorectal surgery is known to lead to complications. This study aims to evaluate whether routine use of fluorescence angiography (FA) alters the incidence of anastomotic leaks after colorectal surgery.

Video magnification for intraoperative assessment of vascular function

Current Directions in Biomedical Engineering, 2017
In neurovascular surgery the intraoperative fluorescence angiography has been proven to be a reliable contact-free optical imaging technique to visualize vascular blood-flow. This angiography is obtained by injecting a fluorescence dye e.g.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Alkyl chain elongation engineering: Unlocking high‐brightness NIR‐II O‐xanthene dyes for in vivo bioimaging

Smart Molecules, EarlyView.
O‐xanthene–based fluorophore enhanced fluorescence quantum yield and brightness were achieved by extending the N‐alkyl chain on the aniline donor. Abstract NIR‐II fluorescent probes are powerful tools for advanced imaging, with performance governed by molar extinction coefficient (ε), quantum yield (Φ), and brightness (ε × Φ).

Indocyanine green fluorescence-guided surgery in acute settings: state-of-the art

Frontiers in Surgery
BackgroundOperating in acute surgical settings is significantly different from elective surgery. One aspect is the complexity of acutely ill or injured patients with abnormal physiology, unoptimized comorbidities, and unplanned interventions. Traditional

Retinal and Cortical Blood Flow Dynamics Following Systemic Blood-Neural Barrier Disruption

Frontiers in Neuroscience, 2017
To consider whether imaging retinal vasculature may be used as a marker for cortical vessels, we compared fluorescein angiography flow dynamics before and after pharmacological disruption of blood-neural barriers.

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

En face localization of retinal telangiectatic capillaries using OCT compared with ICG angiography in chronic vascular macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinal telangiectatic capillaries (TelCaps) are microvascular abnormalities associated with chronic vascular macular oedema and suboptimal response to intravitreal therapy. Targeted laser photocoagulation is beneficial but requires precise localization using indocyanine green angiography (ICG‐A), the reference standard. However, ICG‐A

Does near-infrared (NIR) fluorescence angiography modify operative strategy during emergency procedures?

, 2018
Bowel viability can be difficult to evaluate during emergency surgery. Near-infrared (NIR) fluorescence angiography allows an intraoperative assessment of organ perfusion during elective surgery and might help to evaluate intestinal perfusion during ...
