肝术后局部声像图表现类型

Ultrasonographic appearance of post-hepatectomy in operative position

目的探讨肝术后局部声像图表现类型。方法对176例肝术后患者的手术方式、部位、残腔处填塞物类型及术后不同时间超声表现作一回顾性分析。结果肝术后局部声像图主要表现为:①部分肝叶或肝段缺损;②手术局部形成薄壁囊样局限性无回声区或混合性肿块;③手术部位呈不规则团状高回声;随时间推移手术部位囊样无回声区及混合性肿块边缘表现不规则壁样增厚,内部回声不均匀,部分填塞物及刮吸法手术后“残腔”周边可出现彩色多普勒闪烁伪像。结论肝术后局部超声图像可因手术方式、部位、切除范围大小、残腔有无填塞及填塞物的内容不同而表现多样化。

Objective To investigate the types of ultrasonographic appearance of post-hepatectomy in operative position. Methods The data about operative manner,operative position, type of plugger in residul cavitity of 176 cases who underwent hepatic operation,were collected. Their ultrasonographic findings of post-operative liver in operative position in different phrases after operation were analyzed retrospectively. Results The main appearance was: ① Absence of partial hepatic lobe or hepatic segment; ② anechoic area with thin wall or mixed mass in operative position; ③ conformation of irregular high-echo conglomeration in operative position, irregular wall thickeness and inhomogenous internal echoes appeared in anechoic area and mixed mass in operative position, color Doppler twinking artifact appeared around some plugger and residual cavity which made by curettage and aspiration technique with time passing by. Conclusions Ultrasonographic appearance of post-hepatectomy in operative position varies with different operative manner, operative position, resected area, and Absence or existence of plugger in residual cavity, different type of plugger in residual cavity.
