A case of tubal torsion and blood flow evaluation using intraoperative indocyanine green fluorescence

Abstract

　Fallopian tube torsion is a relatively rare disease and is said to occur in 1 in every 1.5 million women. Sometimes, it is difficult to decide whether to preserve the tube over time after the disease onset. We report a case in which blood flow was evaluated after untwisting of tube by using intraoperative indocyanine green (ICG) fluorescence. A 25-year-old woman was admitted to our hospital for acute abdomen, and laparoscopic surgery was performed because computed tomography (CT) revealed a suspected torsion of the adnexa. A right paratubular cyst was observed, which was in a twisted state. After untwisting, the recovery of blood flow was confirmed by the ICG fluorescence method. The operation was completed by excision of the cyst. Thus, the ICG fluorescence method could be used to confirm the recovery of blood flow after the release of torsion.
