OBJECTIVE Because the microsurgical working space in the interpeduncular fossa is very narrow, using different surgical approaches such as the pterional approach and/or the pretemporal transcavernous approach in combination with a division of the posterior communicating artery (PComm) at the longest perforator-free zone (PFZ) can help to enlarge the microscopic field of view and the working space in this area of the brain. METHODS In this microanatomic study, the variability of several… CONTINUE READING
