成人肾上腺术中超声表现

目的 观察成人肾上腺术中超声（IOUS）表现。方法 收集71例因肝脏、胆道或胰腺病变而接受外科手术治疗患者，观察肾上腺IOUS表现，并与CT/MRI双侧肾上腺显示率和厚度测值进行比较。结果 成人肾上腺IOUS表现为边界清晰、形态不规则的双侧弱回声结构。CT/MRI肾上腺显示率为97.18%（138/142）。IOUS肾上腺显示率为95.07%（135/142），右侧92.96%（66/71）、左侧97.18%（69/71），且可见4侧CT/MRI未能显示的肾上腺；IOUS所测肾上腺厚度均大于CT/MRI（P均<0.05）。结论 IOUS中，成人肾上腺表现为边界清晰、形态不规则的双侧弱回声，左侧显示率高于右侧。

Manifestations of adult adrenal glands in intraoperative ultrasound

Objective To observe the manifestations of adult adrenal glands in intraoperative ultrasound (IOUS). Methods A total of 71 patients who underwent surgery for liver, biliary or pancreatic lesions were enrolled. Adrenal glands manifestations in IOUS were observed, and the displaying rate and the measured thickness of adrenal glands of IOUS were compared with those of CT/MRI. Results Adult adrenal gland manifested as bilateral weak echogenic structures with clear boundary and irregularly shape in IOUS. CT/MRI displaying rate of adrenal gland was 97.18% (138/142), of IOUS was 95.07% (135/142). IOUS displaying rate of the left side adrenal gland was 97.18% (69/71), of the right side adrenal gland was 92.96% (66/71), including 4 adrenal glands not shown on CT/MRI. The thickness of adrenal gland measured with IOUS was greater than those with CT/MRI (all P<0.05). Conclusion IOUS of Adult adrenal glands present as bilateral weak echogenic structures with clear boundary and irregularly shape. IOUS displaying rate of adult adrenal gland was higher of the left side than the right side.
