摘要/Abstract

摘要： 目的探讨经胸右心声学造影(contrast-transthoracic echocardiography, c-TTE)联合对比增强经颅多普勒(contrast-enhanced transcranial Doppler, c-TCD)对卵圆孔未闭(patent foramen ovale, PFO)右向左分流(right to left shunt, RLS)的诊断价值。方法回顾性选取218例PFO患者为研究对象,在平静状态及Valsalva状态下分别行经食管超声心动图(transesophageal echocardiography, TEE)及c-TTE联合c-TCD检查,探讨c-TTE联合c-TCD检查对PFO-RLS的诊断价值。结果 Valsalva动作后PFO-RLS检出率高于平静呼吸状态时(P<0.05);无论平静呼吸状态还是Valsalva动作后,联合检查的PFO-RLS检出率均高于单独c-TTE检查或c-TCD检查(P<0.05);诊断分级为Ⅰ级时,c-TCD的检出率高于c-TTE(P<0.05),而在Ⅱ级及Ⅲ级中两种检查方法的检出率无明显差异(P>0.05);在分级为I级和II级的范围中,联合检查的PFO-RLS检出率均高于单独c-TTE检查或c-TCD检查(P<0.05),而在Ⅲ级中单独c-TTE检查或c-TCD检查或联合检查的PFO-RLS检出率无明显差异(P>0.05)。结论 Valsalva作为可提高右心房压力的辅助动作可提高PFO-RLS检出率。与常规单独c-TTE 检查或单独c-TCD检查相比,联合检查对PFO-RLS具有较高的诊断价值。

Abstract: Objective To investigate the diagnostic value of contrast transthoracic echocardiography(c-TTE)plus contrast-enhanced transcranial Doppler(c-TCD)for patent foramen ovale right to left shunt(PFO-RLS). Methods The data of 218 PFO patients were examined with transesophageal echocardiography(TEE), and c-TTE plus C-TCD in the resting state and Valsalva state, to assess its diagnostic value for PFO-RLS. Results The detection rate of PFO-RLS was significantly higher in Valsalva state than in resting state(P<0.05). In both state, the c-TTE plus c-TCD examination showed a higher detection rate than c-TTE(P<0.05)or c-TCD alone(P<0.05). When patients had grade I disease, c-TCD had a higher detection rate than c-TTE(P<0.05), but there was no significant difference in the detection rate when the disease was Grade II or Grade III(P>0.05). In grade I and II cases, c-TTE plus c-TCD showed a higher detection rate than c-TTE(P<0.05)or c-TCD alone(P<0.05), but there was no significant difference in the detection rate between c-TTE or c-TCD alone, or combined examination in grade III cases(P>0.05). Conclusion The Valsalva maneuver which increases the right atrial pressure can significantly improve the detection rate of PFO-RLS. The sensitivity and accuracy of c-TTE plus C-TCD are significantly improved in the diagnosis of PFO-RLS compared with those of c-TTE and C-TCD alone(P<0.05).
