Abstract

Purpose: We aimed to investigate whether prediction of liver fibrosis using two-dimensional shear wave elastography (2D-SWE) and vascular tree grading using superb microvascular imaging (SMI) are useful for postoperative follow-up in patients with biliary atresia (BA).

Methods: We retrospectively collected data from medical records of 134 patients who underwent ultrasound examination with 2D-SWE or SMI, including 13 postoperative patients with BA and 121 non-BA patients. We investigated the distribution of liver stiffness values with SWE and vascular tree grading with SMI and evaluated correlations between these findings and biochemical indices of liver fibrosis in postoperative BA patients.

Results: The SWE values of the BA group were not significantly different from that of any other disease groups in non-BA patients. In postoperative BA patients, SWE values correlated significantly with aspartate aminotransferase to platelet ratio index (Spearman rank correlation coefficient [r_s] = 0.6380, p = 0.0256) and with the Fib-4 index (r_s = 0.6526, p = 0.0214). SMI vascular tree grading of the BA group was significantly higher than that of the choledochal cyst group (p = 0.0008) and other hepatobiliary disorder group (p = 0.0030). In postoperative BA patients, SMI vascular tree grading was not positively correlated with any biochemical marker of fibrosis.

Conclusion: 2D-SWE appears to be useful for follow-up in postoperative BA patients.

评估二维剪切波弹性成像和超级微血管成像在胆道闭锁术后患者中的应用。

目的：我们旨在研究使用二维剪切波弹性成像（2D-SWE）预测肝纤维化和使用超级微血管成像（SMI）进行血管树分级是否有助于胆道闭锁（BA）患者的术后随访：我们回顾性地收集了134名接受二维-SWE或SMI超声检查的患者的病历数据，其中包括13名胆道闭锁术后患者和121名非胆道闭锁患者。我们用 SWE 和 SMI 调查了肝脏硬度值的分布，并用 SMI 评估了血管树分级，还评估了这些结果与 BA 术后患者肝纤维化生化指标之间的相关性：结果：BA组的SWE值与非BA患者的其他疾病组无明显差异。在术后 BA 患者中，SWE 值与天冬氨酸氨基转移酶与血小板比值指数（Spearman 秩相关系数 [rs] = 0.6380，P = 0.0256）和 Fib-4 指数（rs = 0.6526，P = 0.0214）明显相关。BA 组的 SMI 血管树分级明显高于胆总管囊肿组（P = 0.0008）和其他肝胆疾病组（P = 0.0030）。在术后 BA 患者中，SMI 血管树分级与纤维化的任何生化指标均无正相关。
