Aim: To evaluate the use of intraoperative dye based video angiography in microsurgical management of intracranial vascular pathologies. Material and Methods: The present non randomized prospective observational study was conducted in the Department of Neurosurgery, Bangur Institute of Neurosciences & SSKM Hospital, IPGME &R, Kolkata during Dec 2020 – Dec 2023 among patients admitted to our institute with radiological evidence of intracranial vascular pathologies (Aneurysms, AVMs). Results: Incidence of Aneurysm and AVM among the study subjects was 64% and 36% respectively. Most common symptom among the study subjects was headache (92%) followed by altered sensorium (48%). Most common complication among the study subject during follow up was cerebral vasospasm (14%) and aneurysm rupture (8%). Indocyanine green video angiography (ICG VA) was found to be useful in 98% of the surgical procedure however it influence surgery in 44% of the cases. Conclusion: ICGFV is an intuitive method that provides neurosurgeons with high-quality, reliable, real-time information regarding cerebrovascular anatomy, which can assist in improving intra-operative surgical management and stroke prevention.
