In this study, we evaluated the dynamic blood flow to the retrograde limb of the IMV (retrograde IMV) at the anastomosed site via indocyanine green (ICG) angiography


 In 40 patients undergoing free flap breast reconstruction, we evaluated the dynamic blood flow as "stain(+)" if a stain by ICG was observed and, "flow(+)" if a smooth blood flow was recognized.


 Based on the ICG angiography, "stain(+)" was observed in all cases, but "flow(+)" was detected in only 72.5% of the cases.
