摘要

目的：探讨不同类型无顶冠状静脉窦综合征（UCSS）的超声血流动力学特征及规律性。方法：应用复合超声技术对24例UCSS患者进行检查，所有病例均经CT检查或/和手术证实。结果：24例UCSS中，Ⅰa型14例，Ⅰb型2例，Ⅱa型2例，Ⅱb型2例，Ⅲb型4例。Ⅰa型UCSS的特征表现为左上腔静脉血流回流入左房。Ⅱa型表现为左上腔静脉经冠状静脉窦口回流入右房及中途向左房的“分洪”征。Ⅱb型及Ⅲb型则表现为房水平的左向右分流。结论：UCSS血流动力学因类型及合并畸形的不同而变异较大。综合超声技术尤其是右心声学造影技术可为评价UCSS的血流动力学提供重要信息。

Abstract

Objective: To explore the hemodynamic characteristics and regularity of unroofed coronary sinus syndrome(UCSS) on echocardiograph. Methods: The composite echocardiograph including transthoracic echocardiography(TTE), transesophageal echocardiograph(TEE), real-time three-dimensional echocardiograph(RT3DE) and contrast echocardiograph(CE) was performed in 24 patients with UCSS that were confirmed with CT or surgical findings． Results: Twenty-four cases of UCSS includes 14 cases of typeⅠa, 2 cases of type Ⅰb, 2 cases of type Ⅱa, 2 cases of type Ⅱb, 4 cases of type Ⅲb. Color Doppler flow imaging(CDFI) or CE showed persistent left superior vena cava(PLSVC) draining into the left atrium on type Ⅰa UCSS, PLSVC draining into the right atrium and “spillway-like” shunting into the left atrium and atrial level left to right shunt on type Ⅱb or type Ⅲb. Conclusion: The hemodynamics of UCSS varies greatly depending not only upon its type but also upon various associated congenital anomalies. Its accurate diagnosis is sometimes difficult by TTE due to its atypical hemodynamic manifestations and may reliably be drawn by TEE, RT3DE and especially CE via finding out atrial level shunt or abnormal PLSVC draining into left atrium.
