Complete excision of cutaneous angiosarcoma, which is a rare, vascular, and aggressive tumor, is challenging. Its multifocal nature and propensity for lateral spread make the gross assessment of surgical margins difficult. Neither the use of frozen section analysis nor Mohs surgery consistently improves the probability of margin-free excision. Recent studies have advocated the use of indocyanin...

Plastic and reconstructive surgery relies on the knowledge of angiosomes in the raising of microsurgical flaps. Growing interest in muscle-sparing perforator flaps calls for reliable methods to assess the clinical feasibility of new donor sites in anatomical studies. Several injection techniques are known for the evaluation of vascular territories. Indocyanine green-based fluorescence angiograp...

The rate of removal of a standard dose of 25 mg indocyanine green was studied in 67 patients at the bedside using dichromatic ear densitometry. The determination of the percentage disappearance rate per minute and the half life of the dye permitted separation of patients into three groups: those with normal liver function, those with liver damage, and a group taking opiates (9), anticonvulsants...

We investigate nonequilibrium noise in a diffusive Andreev interferometer, in which currents emerging from two normal metal/superconductor (N-S) interfaces can interfere. We observe a modulation of the shot noise when the phase difference between the two N-S interfaces is varied by a magnetic flux. This is the signature of phase-sensitive fluctuations in the normal metal. The effective charge i...

Modern technologies such as near infrared (NIR) indocyanine green (ICG) fluorescence imaging represent potentially useful tools to facilitate intraoperative assessment of vascularization and tissue perfusion [3]. Recently, the use of a near-infrared fluorescence (NIRF) imaging system using indocyanine green (ICG) dye has been described during robotic partial nephrectomy as an adjunctive means o...

Cimetidine 200 mg three times daily and 400 mg at night was given to 10 subjects for four weeks. Apparent liver blood flow was measured by indocyanine green clearance and microsomal enzyme activity by antipyrine clearance, before and after cimetidine. There was no reduction in indocyanine green clearance but antipyrine clearance, as expected, was significantly reduced by 15% at four weeks. Chro...

In a previous issue of the journal, Oldřich Coufal and Vuk Fait reported a pilot study that specifically addressed the use of indocyanine green for detecting sentinel lymph nodes in breast cancer within a European population. They concluded that fluorescence method cannot currently be considered a method fully comparable with using radioisotopes in this setting. We consider that the absence of ...

OBJECTIVE To determine the elimination kinetics of indocyanine green (ICG) after intraocular operations using ICG staining. METHODS Intraocular fluorescence of ICG was determined using the ICG angiographic mode of a scanning laser ophthalmoscope (in vivo) and fluorescence microscopy (in vitro) after circular curvilinear capsulorhexis with ICG staining during cataract surgery and internal limi...
