NPR: She Survived Breast Cancer, But Says A Treatment Side Effect ‘Almost Killed’ Her

“After Virginia Harrod was diagnosed with stage 3 breast cancer in 2014, she had a double mastectomy. Surgeons also removed 16 lymph nodes from under her armpit and the area around her breast, to see how far the cancer had spread and to determine what further treatment might be needed. Then she underwent radiation therapy.

As it turned out, the removal of those lymph nodes, along with the radiation, put Harrod at risk for another disorder — lymphedema, a painful and debilitating swelling of the soft tissue of the arms or legs, and/or an increased vulnerability to infection.”

Image-Guided Perforator Flap Design Using Invisible Near-Infrared Light and Validation with X-Ray Angiography 

In this study, 22 pigs were injected with a bolus of indocyanine green (ICG) through a central venous line and observed with a near infrared (NIR) camera to identify dominant perforator flaps from the deep superior epigastric artery (DSEA). After the flap was identified and cut, it was given another ICG injection to confirm perfusion. In 8 of 22 of the pigs NIR ICG was confirmed with x-ray angiography. Researchers made a direct correlation between the results of the NIR ICG and x-ray angiography. This 2009 animal study “validated the clinical relevance of ICG fluorescence to tissue perfusion… the use of NIR wavelengths for fluorescence emission minimizes tissue autofluorescence and photo scatter, resulting in relatively high sensitivity” (Matsui et al 4).
