【摘要】：目的利用MSCT准确显示肾上腺静脉正常解剖结构及变异,为临床提供影像解剖数据。方法回顾分析上腹部CTA患者108例。薄层MIP/MPR评估测量肾上腺静脉管径、长度及走行路径。结果 1右侧:显示率64.81%(70/108),变异5.71%(4/70);汇入下腔静脉7点至8点间占优势42.42%;其管径Rr(2.19±0.56)mm,腺外段长度RD1(5.02±1.82)mm,汇入下腔静脉距右肾静脉汇入距离RD2(40.69±12.96)mm,汇入口开口向下角度RA(60.25±17.85)°。2左侧:显示率97.22%(105/108);变异14.29%(15/105);肾上腺静脉管径Lr(2.39±0.56)mm,腺外段长度LD1(7.28±4.01)mm,膈-肾上腺静脉干管径LR(3.65±0.93)mm,膈-肾上腺静脉的共干段长度LD2(14.07±6.77)mm,膈-肾上腺静脉汇入左肾静脉点至下腔静脉左侧缘距离LD3(32.89±4.85)mm,膈-肾上腺静脉汇入左肾静脉开口向内的角度LA1(118.06±18.49)°,肾上腺静脉与膈静脉共干段开口向下的角度LA2(156.15±13.81)°。结论 MSCT可显示大部分右侧肾上腺静脉及绝大部分左侧肾上腺静脉正常走行及变异,测量相关影像解剖数据,为AVS等手术方案提供影像数据。
[Abstract]:Objective to accurately display the normal anatomic structure and variation of adrenal vein by MSCT, and to provide imaging anatomic data for clinic. Methods 108 cases of upper abdominal CTA were retrospectively analyzed. The diameter, length and route of adrenal vein were measured by thin-slice MIP/MPR. Results (1) on the right side, the display rate was 64.81% (70 渭 108), the variation was 5.71% (4 / 70), and the dominant rate was 42.42% between 7 and 8 o'clock in the inferior vena cava (IVC). The diameter of Rr was (2.19 卤0.56) mm, the length of outer segment of gland was (5.02 卤1.82) mm, the distance from the inferior vena cava to the right renal vein was (40.69 卤12.96) mm, from the inferior vena cava to the right renal vein. On the left side, RA (60.25 卤17.85) 掳: the display rate was 97.22% (105 脳 10 ~ 8), and the lower angle of the entrance opening was (60.25 卤17.85) 掳. The variation was 14.29% (15 / 105); Diameter of adrenal vein Lr (2.39 卤0.56) mm, length of outer glandular segment LD1 (7.28 卤4.01) mm, diameter of phrenic-adrenal vein LR (3.65 卤0.93) mm, length of common trunk of phrenic-adrenal vein LD2 (14.07 卤6.77) mm, The distance from the left renal vein to the left edge of the inferior vena cava (LD3) from the phrenic-adrenal vein to the left edge of the inferior vena cava was (118.06 卤18.49) 掳from the phrenic-adrenal vein to the opening of the left renal vein. The angle of descending opening of adrenal vein and phrenic vein was (156.15 卤13.81) 掳. Conclusion MSCT can show the normal course and variation of most right adrenal vein and most left adrenal vein, and measure the relevant imaging anatomic data, which can provide the imaging data for AVS and other surgical schemes.
