Objective: To demonstrate the effectiveness of intraoperative video angiography during microsurgical removal of intramedullary hemangioblastomas of the spinal cord.
Materials and methods: From 2002 to 2018 at N.N. Burdenko NMRCN, 758 patients with
intramedullary spinal cord tumors were operated. Of these, 101 patients were treated for
intramedullary hemangioblastomas, which accounted for 8% of the total number of patients. From June 2017 to August 2018 we performed two operations using the video angiographic mode (HaagStreit Surgical © microscope).
Results: During intraoperative video angiography, in both cases it was possible to visualize feeding arteries and draining veins of a solid tumor component, which allowed to remove the tumor without blood loss and neurological symptoms. In one case, during the control video angiography, tumor residue was detected, which was subsequently removed.
Conclusion: The technique of intraoperative video angiography is a noninvasive, accessible, and reproducible procedure that allows visualizing the anatomical location of feeding arteries, draining veins and the boundaries of a solid component of the intramedullary hemangioblastoma of the spinal cord. The introduction of this technique into routine practice will increase the safety of intramedullary hemangioblastoma surgery and reduce the number of cases of subtotal tumor removal.
