主动脉窦瘤亦称乏氏窦瘤(以下简称窦瘤)是一种较为常见的先天性心脏病,占临床先天性心脏病的1.6％,可单独存在,也可合并其它先天性心脏畸形。窦瘤在破裂之前一般不出现症状,但有的可引起难以解释的心律失常,右室流出道梗阻,三尖瓣关闭不全,主动脉瓣返流或冠状动脉阻塞等。但破裂后发生主动脉与心腔间的异常分流时,临床上即出现症状,心前区急剧疼痛、气急、心悸、脉压加大和指甲床的毛细血管搏动等体征;胸骨左缘2～4肋间及连续性杂音。胸片见肺血多,逆行主动脉造影显示主动脉扩张,造影剂流入右心室或右心房等。我院近年来应用超声诊断本病28例,并均经逆行主动脉造影与手术证实。现分析如下。
Aortic sinus tumor, also known as sinus tumor (hereinafter referred to as sinus tumor) is a more common congenital heart disease, accounting for 1.6% of congenital heart disease, may exist alone, but also may be combined with other congenital heart disease. A sinus tumor generally does not have symptoms before rupture, but some can cause unexplained arrhythmia, right ventricular outflow tract obstruction, tricuspid regurgitation, aortic regurgitation or coronary occlusion. However, after the rupture of the aorta and the heart chamber between the abnormal shunt, the clinical symptoms, acute precordial pain, shortness of breath, palpitations, increased pulse pressure and capillary nail pulsation and other signs; sternal left margin of 2 to 4 Intercostal and continuity murmur. Chest X-ray see more blood, retrograde aortic angiography shows aortic dilatation, contrast agent into the right ventricle or right atrium and so on. In recent years, our hospital ultrasound diagnosis of the disease in 28 cases, both confirmed by retrograde aortic angiography and surgery. Analysis is as follows.
