FNA biopsy, adrenal vein
sampling, and biochemical testing
According to these criteria, the success rate for cannulation of the right adrenal vein
at Greenslopes Hospital has remained =90% since 1999 (2).
31,32) Large adrenal carcinomas tend to invade the adrenal vein
and inferior vena cava.
If there is an adrenal mass, adrenal vein
sampling (AVS) should be tested.
The entire specimen was removed en bloc (Figure 2) consisting of diaphragm, right adrenal metastasis measuring 6 cm x 4 cm x 3 cm, a scant amount of normal adrenal tissue, the small patch of IVC and the right adrenal vein
which was completely encased by tumor.
Radiological studies that aid the diagnosis of adrenal adenomas include contrast-enhanced CT, MRI and adrenal vein
sampling of aldosterone levels.
To this end, adrenal vein
sampling (AVS) is considered the gold standard test, although it may be technically difficult, especially in the catheterization of the right adrenal vein
