Cerebral cavernous malformations (CCMs) are known to be angiographically occult malformations with low perfusion of blood flow. Near-infrared indocyanine green (ICG) video angiography allows for intraoperative observation and documentation of blood flow in large and small vessels. ,
Developmental venous anomalies (DVAs) are thought to be the most common cerebral vascular abnormality. , The opportunity to differentiate intraoperatively between normal veins and DVA draining veins might be useful in the event of a possible venous sacrifice. Coagulation of the DVA can lead to devastating consequences. ICG reliably demonstrates margins between CCM and the venous structures. , For these reasons, we decided to use ICG video angiography in this patient.
