I think I may complicate matters – I tend to want a vascular surgeon to ‘hold my hand’ for L4/5 but I am actually fairly happy for L5/S1.
Do you think that it also depends on local protocols? Some places have vascular surgeons in the same building whom they pre-warn whilst my local vascular service is in a separate hospital.
Due to this we are in the process of organising on site vascular support for an increasing number of our anterior spinal cases.
