为了探讨常用的几种无创伤性检查方法对心包积液的诊断价值,本文对30例经心包穿刺或心包剥离确诊为心包积液患儿的M型超声心动检查做了分析,并与X线、心电图及A型超声检查做了比较。各种检查的诊断符合率:X线检查为13/30(43.33％),心电图为3/30(10％),A型超声为24/27(88.88％),M超声为29/30(96.66％)。M型超声主要表现为液性暗区。当显示右室前壁及左室后壁液性暗区时,积液肯定,且液量较多(平均345ml);仅有左室后壁或右室前壁液性暗区者,亦均发现积液,但液量较少(平均<100ml)。本文资料表明M 型超声心动检查对确诊心包积液具有重要价值,若同时辅以A型超声检查则更可提高确诊率。
In order to explore the commonly used several noninvasive diagnostic methods for the diagnosis of pericardial effusion, this paper analysis of 30 cases of pericardial puncture or pericardial effusion confirmed pericardial effusion in children with M-mode echocardiography was analyzed and compared with X-ray , ECG and A-type ultrasound examination made a comparison. The diagnostic accuracy of various examinations was 13/30 (43.33%) for X-ray examination, 3/30 (10%) for electrocardiogram, 24/27 (88.88%) for type A ultrasound and 29/30 %). M-type ultrasound mainly for the liquid dark area. When showing the right ventricular anterior wall and left ventricular posterior wall liquid dark area, the effusion is positive, and more fluid (average 345ml); only the left ventricular posterior wall or right ventricular anterior liquid dark area, also Found fluid, but less fluid (average <100ml). The information in this paper shows that M-mode echocardiography is of great value in the diagnosis of pericardial effusion, if accompanied by A-mode ultrasound can improve the diagnosis rate.
