[Intraoperative video-angiography in surgery for spinal intramedullary cavernous malformations: first experience of its application at the Burdenko Neurosurgical Center].

Abstract

Spinal intramedullary cavernous malformations are a rare vascular pathology of the central nervous system. They account for 3-5% of spinal cord diseases. The clinical picture in patients with cavernous malformations varies from an asymptomatic course to gross neurological deficit in the case of bleeding from a malformation. Due to the lack of reliable methods for predicting the development of bleeding, the need for surgical treatment of asymptomatic patients remains a relevant and open topic for discussion. The goal of surgical treatment of cavernous malformations is to minimize the risk of repeated hemorrhages and gross neurological deficits in patients. Intraoperative indocyanine green video angiography is a promising technique for intraoperative visualization of the size and adherence area of a cavernous malformation to the spinal cord tissue. This increases the radicality of cavernous malformation resection and minimizes intraoperative risks for the patient.
