Optimizing ICG Dosing for Visualizing Rotator Cuff Blood Flow

Optimal Dosing of IC-Green for Visualization of Rotator Cuff Vascularity Using Advanced Imaging Modality Arthroscopy: A Prospective, Randomized Trial

Phase 1 Interventional NYU Langone Health · NCT04340752

This study is testing different doses of a special dye to see which one best helps doctors see blood flow in the rotator cuff during surgery, which could help reduce the chances of re-injury.

What this trial studies

This study aims to establish an optimal dosing protocol for Indocyanine Green (ICG) to enhance the visualization of vascularity in patients undergoing arthroscopic rotator cuff repair. By assessing the vascularity of the rotator cuff using a fluorescence solution, the study seeks to determine the effectiveness of different doses of ICG based on a surgeon's evaluation using a 5-point Likert scale. The results will be analyzed using ANOVA to compare the means of the vascularity assessments across the various doses administered. This could provide valuable insights into the relationship between vascularity and the risk of rotator cuff re-tear.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 79 who have full or partial thickness rotator cuff tears and are scheduled for arthroscopic repair.

Not a fit: Patients under 18 or over 79 years old, those with allergies to iodides, or those who have had iodide-based imaging studies recently may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes by identifying optimal vascular conditions that reduce the risk of rotator cuff re-tear.

How similar studies have performed: While there have been no prior human studies specifically assessing ICG for rotator cuff vascularity, the use of ICG for visualization in other surgical contexts has shown promise.
