Objective To evaluate the application of multi-slice spiral CT angiography (MSCTA) to show the feasibility of the center of the left adrenal vein (LAV), and further anatomical and genetic variation analysis system. Materials and Methods A retrospective analysis of 400 routine on enhanced abdominal scan in patients with arterial phase and venous phase data workstation, multi-plane reorganization (MPR), maximum intensity projection (MIP), and volume reproduction (VR). Display rate of the statistical center of the left adrenal vein and the left adrenal the central venous developing clear cases observed study of normal anatomy and variation, and then measuring the edge of the left adrenal gland to LAV and the left inferior phrenic vein (LIPV) Interchange length (D1), LAV LIPV Interchange distance of LAV and left renal vein (LRV) the interchange the length (D2), LAV LIPV confluence trunk after import LRV at the left side of the wall to the abdominal aorta (AA) (D3), LAV and LIPV confluence for the trunk after the import the LRV's angle (a), the LAV the inner diameter (γ). Results in 400 patients developing well (378/400) in 94.5% of the left adrenal central vein, D1, D2, D3, alpha, gamma, mean 15.2 ± 0.36mm, 16.4 ± 0.38mm, respectively, 4.7 ± 0.09mm 3.1 ± 0.18mm, 66 ± 1 2.06. . Found the variation 61 cases, accounting for 16.1% (61/378) in the 378 patients developing. (1) the left adrenal central vein and the left inferior phrenic vein enters the left renal vein in 8 cases, accounting for 2.1% of the left adrenal gland near the kidney at the central venous import side, while the left the subdiaphragmatic venous import at close to the lower vena cava side; see Figure 9 (Fig.9) (2) left adrenal central vein and left suprarenal vein confluence enters the left renal vein, 11 cases (2.9%); see Figure 10 (Fig.10) (3 ) left renal vein the annular surrounding the abdominal aorta, and adrenal central vein ring loop on the support of two cases, accounting for 0.5%. Shown in Figure 2 (Fig.2) (4) left renal vein renal hilum is divided into two up and down, left adrenal central vein import support one cases, accounting for 0.3% shown in Figure 3 (Fig. 3) (5) the upper edge of the left renal vein, only the left adrenal central vein import, and the left inferior phrenic vein was not imported to the center of the left adrenal vein 30 cases, accounting for 7.9%; see Figure 11 (Fig.11) (6) the center of the left adrenal gland enters the left renal vein the vein and unknown venous confluence; 12 (See Fig.12.) (7) left adrenal central vein with unknown vein enters the left renal vein, the left adrenal central vein import at close to the lower side of the superior vena cava, and unknown vein near the kidney side import at. Shown in Figure 13 (Fig.13) Conclusion and significance MSCTA central vein of the left adrenal higher rate display clearly shows the anatomy of the central vein of the left adrenal gland and variation for clinical surgery can provide reliable information about the anatomy .
