Advances in imaging technology have provided new diagnostic methods for assessment of cerebral vascular perfusion and quantitative analysis of the microcirculation during cerebral surgery. In this article, a range of imaging procedures are described: Digital Subtraction Angiography (DSA) and Three-Dimensional Computed Tomography Angiography (3D-CTA), Indocyanine Green Video Angiography (ICGVA),...

Lacquer cracks are thought to represent healed mechanical breaks in the retinal pigment epithelium, Bruch's membrane, and choriocapillaris complex. In this study, we analyzed the indocyanine green (ICG) angiographic features of lacquer cracks and compared them with findings using fluorescein angiography. Complete ophthalmologic examinations, fluorescein angiography, and ICG angiography were per...

BACKGROUND Extravasation of cytotoxic drugs is a serious complication of systemic cancer treatment. Still, a reliable method for early assessment of tissue damage and outcome prediction is missing. Here, we demonstrate that the evaluation of blood flow by indocyanine green (ICG) angiography in the extravasation area predicts for the need of surgical intervention. METHODS Twenty-nine patients ...

Indocyanine green (ICG) video angiography has been used for several medical indications in the last decades. It allows a real time evaluation of vascular structures during the surgery1,2,3,4,5. Indocyanine green dye was developed for near-infrared photography by the Kodak Research Laboratories in 1955 and was already approved for clinical use in 1956. However, it was used for angiography in the...

PURPOSE To identify signs occurring more frequently in retinal angiomatous proliferation (RAP) lesions compared with other types of choroidal neovascularization (CNV) in age-related macular degeneration. METHODS In this cross-sectional retrospective study, 30 patients were evaluated. These signs were correlated with the type of CNV: shunting of blood flow to the lesion by fluorescein angiogra...
