Experimental: Adrenal venous sampling
Patients going trough an adrenal venous sampling to find out if hypercortisolism is uni or bilaterally produced.
Radiation: Adrenal venous sampling
We go trough the femoral vein with a catheter up to the adrenal vein first on the left side, then on the right side. We take blood samples and analyze cortisol, metanefrin/ normetanefrin, aldosterone both from the adrenal veins and from the peripher vein. Then we use criteria from the Majo clinic to identify if the overproduction of cortisol is uni- or bilateral.
- Lateralisation of cortisol overproduction [ Time Frame: 2 yeras ]If the ratio between cortisol in the adrenal veins is over 3,3 , it is defined as unilateral overproduction of cortisol.
- Biochemically and clinically normalising after treatment [ Time Frame: 2 years ]The patients will be offered operation if the overproduction seems to be unilateral. They will then be evaluated for cortisol abnormalities , blood sugar, and hypertension i intervals of 6 months after surgery ,to see if the parameters improve. They who are not operated will be evaluated in the same way.
- Verify overproduction of cortisol from the adrenals [ Time Frame: 2 yeras ]If the ratio between cortisol in the adrenal vein and the periphery vein is over 3,3 it is defined as overproduction, and if it is over 6,5 it will probably be an adenoma.
