【摘要】 总结了应用美国 ATL 生产的 Mark超 6型、HDI超 9和 5 0 0 0型彩色多普勒诊断仪诊断的 6 0例风湿性心脏病二尖瓣病变合并左房血栓的资料 ,用以探讨二尖瓣病变与左房血栓的关系。结果表明 :(1)左房血栓多发生在二尖瓣中度、重度狭窄时 (5 9例 ,占 98.3% ) ;并以重度狭窄患者为多 (48例 ,占 80 % ) ;(2 )左房血栓多发生在单纯二尖瓣狭窄或仅合并轻度 ( 度 )关闭不全患者 (5 6例 ,占 93.3% ) ,而合并中度 ( 度 )和重度 ( 度 ) ,返流患者则较少形成血栓 (仅 4例 ,占 6 .7% ) ;(3) 5 4例 (占 90 % )患者合并心房纤颤 ;(4)血栓多位于左心耳 (2 9例 ,占 48.3% )和左房顶部 (2 1例 ,占 35 % ) ,等血流平缓处 ,作者认为左房血栓形成确与二尖瓣病变尤其是二尖瓣狭窄程度以及左房血流状态和性质、左房功能失调有关。更多还原

【Abstract】 Objective: To approach into the relationship between left atrial thrombosis(LA-Th) and rheumatic mitral valular disease. Methods: Sixty cases of rheumatic mitral stenosis (MS) complicated with LA-Th were investigated and analyzed by pieces of ATL ultra 6, ATL HDI ultra 9 and Type 5000 color doppler ultrasonic apparatus. Results: (1) Over 98%(59/60) of LA-Th were found in moderate and severe MS, with 80% (48/60) in severe cases; (2) LA-Th were usually (56/60) found in simple MS or those complicated with light(degreeⅠ) mitral regurgitation (MR), only 4 cases in MS complicated with moderate(degreeⅡ) or severe (degree Ⅲ) MR; (3) 90% of them (54/60) were complicated with atrial fibrillation; (4) LA-Th were usually located in the left auricle (29/60 or 48.3%) and the top of left atrium(21/60 or 35%) where the blood flow slowly. Conclusion: The results suggest that the formation of LA-Th is related to mitral valve diseases, especially to the degree of MS, characteristics of blood flow in LA and LA dysfunction.更多还原
