Clinical Applications of Indocyanine Green Fluorescence Imaging in Vascular Malformations: A Systematic Review

Key Takeaways for GI Nurses

• Indocyanine green (ICG) fluorescence imaging is emerging as a valuable diagnostic and therapeutic tool for identifying and treating vascular malformations during endoscopic procedures
• This imaging technology can enhance visualization of abnormal blood vessels that may be difficult to detect with standard white light endoscopy, potentially improving diagnostic accuracy
• Understanding ICG fluorescence protocols and equipment operation will become increasingly important as this technology gains adoption in gastroenterology and endoscopy units
• The systematic review format suggests growing evidence base supporting ICG use, indicating this may become standard practice requiring nursing competency development

Clinical Relevance

The application of ICG fluorescence imaging in vascular malformations represents a significant advancement for endoscopy nursing practice. As this technology becomes more prevalent, GI nurses will need to develop competencies in pre-procedure preparation, including patient education about ICG administration, allergy screening for iodine sensitivity, and understanding contraindications. During procedures, nurses must be familiar with the fluorescence imaging systems, including proper setup, troubleshooting, and optimization of image quality to support accurate diagnosis and treatment of vascular lesions.

From a patient care perspective, ICG fluorescence imaging may improve outcomes for patients with gastrointestinal bleeding from vascular malformations, particularly in challenging cases where standard endoscopy fails to identify bleeding sources. This technology could lead to more targeted interventions, reduced procedure times, and decreased need for repeat procedures. Nurses play a crucial role in monitoring patients during ICG administration, watching for adverse reactions, and ensuring optimal imaging conditions through proper room lighting and equipment positioning.

Unit operations will also be impacted as facilities integrate this technology. Nursing staff will need training on new equipment, updated policies and procedures, inventory management for ICG supplies, and coordination with pharmacy services for drug preparation. The systematic review nature of this research suggests robust evidence is building, making it likely that professional development programs and certification requirements will soon include ICG fluorescence competencies as standard expectations for advanced endoscopy nursing practice.

Bottom Line

ICG fluorescence imaging for vascular malformations represents an evolving standard of care that will require GI nurses to expand their technical skills and clinical knowledge base, ultimately enhancing their ability to support more precise diagnosis and treatment of challenging vascular lesions while maintaining the highest standards of patient safety and care quality.
