为评价增强薄层CT(TSCT)在肾上腺静脉采样(AVS)前显示右肾上腺静脉(RAV)解剖结构的价值，对151例AVS患者在血管造影(介入CT)过程中进行连续CT扫描。其中72例在动静脉曲张前进行了TSCT。皮质醇测量证实RAV插管成功。TSCT上的RAV被分类为确定的、可能的或未识别的，确定或可能识别的病例被归类为有用的。在AVS成功的病例中，将从有用的TSCT中推测的RAV的解剖特征，包括下腔静脉的位置、椎体水平和到右肾上极的距离，与介入CT所确定的RAV特征进行比较。比较使用和不使用TSCT的患者介入前的插管成功率，总共有66例TSCT被归类为有用的。TSCT的解剖特征与介入CT的解剖特征显著相关。有无TSCT的插管成功率估计分别为92.4%和82.4%，TSCT清楚地显示了RAV的解剖特征，便于准确取材，提高了成功率。
To evaluate the usefulness of enhanced thin-slice computed tomography (TSCT) for delineating the right adrenal vein (RAV) anatomy before adrenal vein sampling (AVS).A total of 151 consecutive AVSs with CT during angiography (interventional CT) were included. Of them, TSCT was performed before AVS for 72 patients. Successful RAV cannulation was confirmed using cortisol measurement. The RAV on TSCT was classified as certain, probable, or unidentified, and cases with certain or probable RAV identification were classified as useful. In the cases where AVS was successful, the anatomical features of the presumed RAV from the useful TSCT, including the position along the inferior vena cava, vertebral level, and distance from the upper pole of the right kidney, were compared with the RAV features identified on interventional CT. Estimated successful cannulation rates before interventional CT were compared between patients with and without useful TSCT.In total, 66 TSCTs were classified as useful. The anatomical features identified on TSCT were significantly correlated with those on interventional CT. The estimated successful cannulation rates for cases with and without useful TSCT were 92.4 and 82.4 %, respectively.TSCT clearly shows the anatomical features of the RAV, facilitating accurate sampling and increasing the success rate.
