“…Most patients present histological adenoma patterns characterized by sparsely or dense pitu- (1,6,(20)(21)(22)(23)26). Patients who showed a significant gradient between the pituitary (central) and peripheral ACTH values in the inferior petrosal sinus sampling present better prognosis (27). Some studies describe the presence of major aggressiveness in male subjects, resulting in worse surgical results (6,28).…”

“…Early works on unilateral inferior petrosal sinus and jugular vein sampling (Corrigan et al, 1977;Findling et al, 1981;Drury et al, 1982) have emphasized the importance of bilateral simultaneous inferior petrosal venous sampling which should be performed if more reliance is to be placed on the results (Manni et al, 1983;Doppman et al, 1984;Oldfield et al, 1985;Zovickian et al, 1988). It has also been reported subsequently that bilateral inferior venous sampling may give rise to false negatives (Cuneo et al, 1985;Kageyama et al, 1985).…”

“…Na doença de Cushing, onde há uma fonte hipofisária com produção excessiva de ACTH ocorre um gradiente central periférico na concentração de ACTH (20,21). Adicionalmente, este teste permite a localização do lado onde se encontra o microadenoma hipofisário, auxiliando o cirurgião no momento do procedimento e aumentando a chance do sucesso da cirurgia transesfenoidal (20)(21)(22), mesmo em crianças (23).…”

“…O teste com altas doses de dexametasona pode ser realizado em dose única noturna, apresentando a mesma sensibilidade e especificidade diagnóstica, porém sem o inconveniente de longas internações para o paciente (4,36,37). Finalmente, o teste de oCRH (1µg/kg peso corporal) tem sido extensivamente utilizado no diagnóstico diferencial da síndrome de Cushing, tanto como teste periférico como durante o cateterismo de seio petroso inferior (21,22). Em relação à síndrome de Cushing, os adenomas corticotróficos liberam ACTH e cortisol pós-CRH, com um incremento, em relação ao basal, de 35% e 20% do ACTH e do cortisol, respectivamente (38).…”
