Multi-slice computed tomography imaging anatomy study of adrenal vein
Objective Using MSCT to display the normal anatomic structure and variation of the adrenal vein accurately and to provide image anatomy data for clinical application. Methods 108 patients with abdominal examination of CTA were retrospectively analyzed. A thin layer of MIP and MPR technique was applied to evaluate and measure the adrenal vein diameter, length and line path. Results ① Display rate and variation rate in the right side was 64.81% (70/108) and 5.71% (4/70). The adrenal vein drained directly into the inferior vena cava in 7 o'clock to 8 o'clock direction, accounting for a majority of 42.42% (28/66). The diameter of adrenal vein was (2.19±0.56) mm, the length of vein outside the gland was (15.02± 1.82) mm, the distance between the sites where the right and left the adrenal veins joint the inferior vena cava was (240.69±12.96) mm; the inferiorly-oriented angel of adrenal vein into the inferior vena cava was (60.25± 17.85)°. ② Display rate and variation rate on the left side was 97.22% (105/108) and 14.29% (15/105); adrenal vein was (2.39±0.56) mm, the length of vein outside the gland was (17.28±4.01) mm, the shared trunk between the diaphragmatic-adrenal veins was (3.65±0.93) mm, the distance from the point of diaphragmatic-adrenal vein draining into the left renal vein was (14.07±6.77) mm, the distance from the point of the diaphragmatic-adrenal vein draining into the left renal vein to the left side of the inferior vena cava was (32.89±4.85) mm, the inward angel of the diaphragmatic-adrenal vein drainging into the left renal vein was (118.06±18.49)°,the inferiorly-oriented angel of the adrenal vein draining into the diaphragmatic-adrenal vein(156.15± 13.81)°. Conclusion MSCT can display most of the right adrenal vein and the vast majority of the left adrenal vein in normal and abnormal passageway. Measurement of relevant imaging anatomy data can provide the imaging data for operation scheme such as AVS.
