Abstract

BACKGROUND

Ultrasound follow-up of transjugular intrahepatic portosystemic shunt (TIPS) is challenging due to the bent course of the stent-graft.

OBJECTIVE

Aim of this retrospective study was to assess to which extent the combination of HR flow with Glazing Flow improves hemodynamic assessment in the ultrasound follow-up of TIPS.

METHODS

Comparative studies with CCDS and High Resolution (HR)-Flow with Glazing Flow were evaluated regarding image quality and artifacts on a 5-point scale (0 = cannot be assessed up to 5 = maximum image quality without artifacts). In all cases, an experienced examiner performed the examinations with a 1-6 MHz probe (Resona 7, Mindray).

RESULTS

61 ultrasound examinations in 48 patients were performed; the mean patient age was 54±14.2 years. The use of HR-Flow with Glazing Flow resulted in an improved flow display in 55/61 cases (90.2%). Both methods correlated well (r = 0.71), but HR flow with Glazing flow values were in general higher than CCDS values. The reading resulted in an average value of 2.52±0.54 for CCDS and 3.52±0.57 for HR flow with Glazing flow (p = 0.013).

CONCLUSION

The combination of HR-Flow and Glazing Flow results in improved flow representation and reduction of artifacts in the ultrasound follow-up of TIPS.

摘要

背景

由于支架移植物的弯曲路径，经颈静脉肝内门体分流术（TIPS）的超声随访具有挑战性。

目的

本回顾性研究旨在评估 HR 流量与 Glazing Flow 的结合在 TIPS 超声随访中在多大程度上改善血流动力学评估。

方法

使用 CCDS 和高分辨率（HR）-Flow with Glazing Flow 对具有 5 分制（0=无法评估至 5=无伪影的最大图像质量）的图像质量和伪影进行了比较研究。在所有情况下，一位经验丰富的检查者使用 1-6 MHz 探头（Resona 7，Mindray）进行检查。

结果

对 48 例患者的 61 次超声检查进行了评估；患者的平均年龄为 54±14.2 岁。使用 HR-Flow with Glazing Flow 可改善 55/61 例（90.2%）的血流显示。两种方法相关性良好（r=0.71），但 HR 流量与 Glazing flow 值通常高于 CCDS 值。读数结果平均为 CCDS 为 2.52±0.54，HR 流量与 Glazing flow 为 3.52±0.57（p=0.013）。
