Abstract

Objectives: This study aimed to identify the incidence of adrenal hemorrhage (AH) after OLT and to summarize the ultrasound (US) and contrast-enhanced ultrasound (CEUS) characteristics.

Methods: Patients with adrenal lesions after OLT at our hospital were retrospectively reviewed between January 2010 and November 2023. The reference diagnosis was defined on the basis of surgical data, computed tomography scans, and magnetic resonance imaging with at least 12 months of follow-up. The incidence of AH and the US and CEUS characteristics after OLT were analyzed and compared with those of adrenal metastases.

Results: A total of 23 patients (1.2%) with AH and 7 patients (0.35%) with suprarenal metastases were assessed. Compared with metastases, hematomas had more inhomogeneous echotextures (57% vs. 0.00%, P = 0.010), hypoechoic or mixed-echoic patterns (96% vs. 71%, P = 0.022), and anechoic areas (52% vs. 0.00%, P = 0.024), and their echotextures varied more over time (65% vs. 0.14%, P = 0.031). CEUS was performed on 12 patients with AH and 2 patients with metastases. A "jet-like" contrast superflux was observed in one actively bleeding hematoma, whereas no enhancement was observed in any static hematoma (100%). However, adrenal metastases had a contrast-enhanced appearance in the early arterial phase, followed by fast washout in the late phase (100%), and the difference was statistically significant (P < 0.001).

Conclusion: The sonographic characteristics of AH after OLT vary over time. CEUS is recommended when adrenal lesions are detected, as CEUS can differentiate AH from metastases.

正位肝移植术后肾上腺出血的对比增强超声外观：一项回顾性研究。

研究目的本研究旨在确定OLT术后肾上腺出血（AH）的发生率，并总结超声（US）和对比增强超声（CEUS）的特点：方法：回顾性研究2010年1月至2023年11月期间我院OLT术后肾上腺病变的患者。根据手术数据、计算机断层扫描和磁共振成像结果以及至少 12 个月的随访确定参考诊断。分析了AH的发病率以及OLT后的US和CEUS特征，并与肾上腺转移瘤的特征进行了比较：结果：共评估了 23 例（1.2%）AH 患者和 7 例（0.35%）肾上转移患者。与转移瘤相比，血肿具有更多的不均匀回声（57% vs. 0.00%，P = 0.010）、低回声或混合回声模式（96% vs. 71%，P = 0.022）和无回声区域（52% vs. 0.00%，P = 0.024），其回声随时间变化更大（65% vs. 0.14%，P = 0.031）。对 12 名 AH 患者和 2 名转移灶患者进行了 CEUS 检查。在一个活动性出血血肿中观察到 "喷射状 "造影剂上溢，而在任何静止血肿中均未观察到增强（100%）。然而，肾上腺转移瘤在早期动脉期出现对比度增强，随后在晚期快速消退（100%），差异有统计学意义（POLT 后 AH 的声像图特征随时间而变化。当发现肾上腺病变时，建议使用 CEUS，因为 CEUS 可以区分 AH 和转移瘤。
