Objective:
This study assessed the feasibility and safety of intraoperative indocyanine green (ICG) fluorescence imaging via lower-extremity venous injection to visualize the left common iliac vein (LCIV) during laparoscopic sacral colpopexy (LSC).
Design:
Retrospective 2-center study.
Setting:
Yokohama City University Medical Center and Odawara Municipal Hospital.
Participants:
Patients who underwent LSC between April 2022 and January 2026 were included. Patients with vascular anatomical variations at the sacral promontory or contraindications to ICG were excluded.
Intervention:
To facilitate visualization of the LCIV, ICG was administered via the left dorsal foot vein immediately before retroperitoneal incision at the sacral promontory. The primary outcome was the visualization rate of the LCIV using ICG. Secondary outcomes were the incidence of vascular injury and ICG-related adverse events.
Results:
Overall, 35 patients were included. Successful LCIV visualization was achieved in 31 patients (88.6%). No intraoperative vascular injuries or ICG-related adverse events occurred.
Conclusion:
Intraoperative ICG fluorescence imaging via lower-extremity venous injection is a feasible and safe technique for visualizing the LCIV during LSC and may potentially become a valuable adjunct for identifying the LCIV in patients with standard vascular anatomy.
