Summary
Indocyanine green (ICG) imaging systems, like the HyperEye Medical System (HEMS), offer real-time visualization of blood flow during cardiovascular surgery. This technology aids in detecting anastomotic issues and preventing complications like ischemic colitis.
Area of Science:
- Cardiovascular Surgery
- Medical Imaging
- Surgical Technology
Background:
- Coronary artery bypass grafting mortality is low, but intraoperative assessment of anastomoses is crucial.
- Preventing ischemic colitis during abdominal aortic aneurysm surgery requires direct evaluation of intestinal blood flow.
- Indocyanine green (ICG) fluorescence imaging is a promising tool for intraoperative assessments.
Purpose of the Study:
- To review current strategies for intraoperative blood flow assessment using ICG imaging in cardiovascular surgery.
- To highlight the utility of ICG imaging systems, such as HEMS, in improving surgical outcomes.
- To explore the potential of combining ICG imaging with quantitative flow measurement tools.
Main Methods:
- Review of existing literature and technologies for intraoperative blood flow assessment.
- Focus on Indocyanine green (ICG) fluorescence imaging techniques.
- Evaluation of the HyperEye Medical System (HEMS) and its capabilities.
Main Results:
- ICG imaging provides clear visualization of blood flow and ischemic areas with color.
- HEMS offers enhanced visualization for cardiovascular and abdominal aortic surgeries.
- Combination with transit time flow measurement may improve accuracy.
Conclusions:
- ICG imaging systems represent a significant advancement in intraoperative blood flow assessment.
- These systems can aid in real-time decision-making during complex cardiovascular procedures.
- Further integration with quantitative tools can enhance diagnostic precision and patient safety.

To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.
