The authors analyze 15 patients who underwent pre-operative management
prior to the pheochromocytoma removal. The purpose of this analysis i
s to evaluate the relation between clinical and haemodynamic criteria
evaluating the level of alpha-adrenergic blockade. The authors believe
that pre-operative management based on clinical criteria does not nec
essarily ensure adequate alpha-adrenergic blockade. Invasive monitorin
g of haemodynamic variables is considered an important strategy for th
e quantification of actual haemodynamics status of patients with pheoc
hromocytoma.
