Objective To investigate the technical points of adrenal vein sampling (AVS). Methods AVS examinations were performed in 112 patients with suspicious primaiy aldosteronism. The angiographic manifestations of both adrenal veins were recorded. The clinical data and imaging findings were retrospectively analyzed. The success rate of superselective catheterization and the occurrence of complications were calculated. Results The most common angiographic pattem of left adrenal vein was gland-like type, while the right adrenal vein presented most commonly as triangular pattern. In patients who had the ratio of adrenal hlood cortisol to peripheral blood cortisol ≥ 3 , the superselective catheterization of left and right adrenal vein was succeeded in 106 cases (94.6％) and in 103 cases (92.0％) . respectively, although no statistically significant difference existed between two groups (P = 0.42). The occurrence of complications in left and right group was 2.7％ (2/106)and 6.3％ (7/103). respectively. Conclusion Sufficient knowledge of the angiographic manifestations of adrenal veins is the essential prerequisite to a successful AVS performance.With higher success rate of catheterization ancl fewer complications, AVS is a reliahle and effective examination methocl for the typing and side-localizing of primary aldosteronism.
