Abstract
Abstract
Background
Adrenal venous sampling (AVS) is the gold standard to identify aldosterone-producing adenoma and bilateral adrenal hyperplasia. The present study aims to report the success rate of AVS and distribution characteristics of the right adrenal vein orifice(RAVO).
Methods
166 patients diagnosed as primary aldosteronism, and who underwent AVS, were retrospectively reviewed.
Results
The success rates of right and left blood samplings were 91.0% and 94.3%, respectively. The success rate of bilateral blood samplings was 86.1%. The success of left blood samplings was statistical significance in weight (p = 0.03). The 151 patients whose right blood samplings were successful were divided into 5 groups according to the RAVO. In 130 (86%) of the 151 patients, the RAVO was mainly located at a level ranging from the upper segment of T11 to the lower segment of T12. Ages were statistical significance among 5 groups (p = 0.001).
Conclusions
The success rate of AVS in present study was rather high. The RAVO was mainly located at a level ranging from the upper segment of T11 to the lower segment of T12. The lower age were associated with the higher level of RAVO.
