Preliminary Application Of Indocyanine Green Angiography In The Operation Of Super Cervical Spinal Cord Hemangioblastomas

ObjectiveTo explore and summarize the value of indocyanine green angiography in the microsurgery of super cervical spinal cord hemangioblastoma.MethodsDate from the medical records of 8 patients with super cervical spinal cord hemangioblastoma microsurgieally treated from February 2012 to April 2016 were reviewed.The tumors of 8 patients were resected using the Petero fluorescence microscope,the surgery was performed using posterior midline approach to remove the tumors.In the process of microsurgery,application of indocyanine greenangiography,The location,direction and number of tumor feeding arteries and draining veins were determined according to the fluorescence development.Carefully identify clear after the first coagulation and breaking away from the tumor feeding artery,after transection of tumor,reduce the tension of the color fades,then close to the tumor body surface tumor and spinal cord edema along the fiber interface with a blunt sharp separation of tumor tissue,finally breaking away from the venous drainage,will be the whole tumor resection.The spinal cord function was assessed by McCormick spinal cord functional status before operation,1 weeks after operation and 3 months after surgery.MRI of cervical spinal cord was reviewed for 1 week after operation and3 months after surgery.image contrast before and after surgery to evaluate the extent of tumor resection.ResultsNo contrast agent-related adverse events occurred in 8 patients during procedure.all the patients profited indocyanine green angiography and avoid disastrous intraoperative bleeding and hemostasis-related manipulative injury to the spinal cord.Postoperative pathological diagnosis:8 patients had hemangioblastoma.McCormick grade was compared between pre-operation and post-operatio,neurological conditions were improved in 8 patients.post-operative reexamine results confirmed the total resection of the tumor and achieved ideal therapeutical effect.ConclusionsSuper cervical spinal cord hemangioblastomacan be completely resected by microsurgery and obtain a good prognosis.Indocyanine green angiography is contribute to identify the tumor feeding artery,the draining vein and the boundary of the tumors.Achieving accurate treatment can reduce intraoperative bleeding and prevent spinal cord injure.This technique improves the safety and effectiveness of surgical treatment of super cervical spinal cord hemangioblastoma.
