Application of Indocyanine Green Videoangiography in Cerebellar Hemangioblastoma Surgery as a Valuable Adjunctive Surgical Tool

Abstract Introduction : Surgery for cerebellar hemangioblastoma can be challenging because of the tumor’s location in the posterior fossa and its inherent nature of hypervascularity. Methods We reviewed a total of seven consecutive patients who received microsurgery adjunction with indocyanine green (ICG) videoangiography. Results Our study included four female and three male patients. All tumors were located in the cerebellum. We used ICG videoangiography for the purposes of identifying a small tumor inside the cyst in one case, for defining feeding arteries and draining veins in three cases, for confirming residual tumor in the resection cavity in two cases, and for assessment of tumor shunt flow in one case of extremely hypervascular hemangioblastoma. Median blood loss during surgery was 100 mL, and total resection was achieved in all cases with no complications. No adverse effects of ICG videoangiography were observed. Conclusions ICG videoangiography is a very useful adjunctive tool for cerebellar hemangioblastoma surgery.
