Thermal diffusion blood flow monitoring during aneurysm surgery.
Cortical blood flow (CoBF) monitoring with a thermal diffusion flow probe was performed during the clipping of aneurysms of the ICA and MCA regions, on a series of patients during the acute stage of subarachnoid haemorrhage. Emphasis was placed on the CoBF recovery after temporary clip release. Since the absolute value in this technique is unreliable, recovery of blood flow after temporary clipping is represented as %CoBF according to the following equation: [see text]
