Adrenal vein catheterization. Anatomic considerations.

Twenty post-mortem specimens and 93 phlebographies (56 right side, 37 left side) from 44 patients were investigated with respect to the adrenal venous anatomy. At autopsy, the venous orifices displayed in the area of adrenal drainage were injected bilaterally to identify the adrenal vein(s), the surrounding channels and the presence of interconnections. The findings were correlated with those at clinical phlebography, and the different sources of error were elicited. These were mainly found on the right side. Some guidelines are suggested in the hope that these will contribute to eliminate misconceptions.

Computed tomography of the normal adrenal gland. Pathologic implications.

Computed tomography of the adrenals from 100 selected patients and from adrenal models was used to investigate the morphology, anatomic relations, and transaxial imaging of the normal glands. The recorded data were correlated with the classical anatomy and with the relevant reports in the literature. A system of nomenclature which is felt to be best suited for describing normal and pathologic adrenals, besides being applicable to all specialties, is suggested. Some sources of diagnostic errors were disclosed by reviewing the concepts of the normal axial imaging in the light of pathologic adrenal characteristics.

Computed tomography and angiography in the evaluation of adrenal diseases.

Computed tomography, adrenal venous blood sampling, phlebography and arteriography were compared as diagnostic methods in 50 proven cases of adrenal disease. The diagnostic accuracy was 90 per cent for CT, 100 per cent for adrenal venous sampling, 75 per cent for phlebography and 58 per cent for arteriography. It was necessary in some instances to correlate the findings for more than one modality to reach a correct diagnosis. From an analysis of the different examination methods a sequence in the radiologic evaluation of the pathologic adrenal gland is suggested. CT can be used to advantage as the primary imaging method. However, the other modalities, still play an important role.
