Application of a self-developed, low-budget indocyanine green camera in surgical imaging – a single institution's experiences

Abstract

Introduction: Indocyanine green is a fluorescent dye, the use of which is becoming more and more widespread in many areas of surgery. Several international studies deal with the dye’s effectiveness in intraoperative angiography, the search for tumors, the more precise identification of anatomical structures, the detection of lymph nodes and lymph ducts, etc. The application of the dye is safe, but a suitable equipment park is required for its use, which entails relatively high costs. Objectives: The aim of our research is to create a detector system on a low budget, able to be used safely in everyday practice and to illustrate its operation with practical examples in our own institute. Methods: By modifying a web camera and using filter lenses and special LEDs, we created a device suitable for exciting and detecting indocyanine green fluorescence. We prove its excellent usability during the following surgeries at our institute: breast tumor surgery, kidney transplantation, bowel resection, parathyroid surgery and liver tumor resection. Results: A low budget, easy-to-use tool was created, which is suitable for taking advantage of the opportunities provided by indocyanine green.
