In-House Handmade Camera for Indocyanine Green Video Angiography

Abstract

Background and Aim: Vascular imaging during surgical procedures is very important and has many applications. There are several methods for intraoperative vascular assessment such as intraoperative angiography, Doppler, and fluorescence-based techniques. The latter group and specially the Indocyanine Green (ICG) Video Angiography (VA) is commonly used for vascular surgery and sentinel node biopsy. However, the cost of these microscope mounted cameras limit their availability in the developing countries. Considering this limitation, we designed and constructed a simplified low-cost camera for real-time ICG angiography. In this article, we describe the device structure and give a preliminary report on its usage in an animal model. Methods and Materials/ Patients: ICG-VA camera was designed and constructed in our laboratory. The device consists of optic filters, light sources, and cameras. Results: After inducing anesthesia and exposing mesenteric vessels in a mouse, ICG-VA of these vessels were taken and recorded. Conclusion: Considering the very low cost of the device and its acceptable image quality, it can be utilized in operation theatres and or laboratories for research purposes.
