摘要： 目的探讨经颅多普勒超声微泡实验对脑梗死患者卵圆孔未闭(PFO)的诊断价值。方法运用经颅多普勒超声微泡实验对经食管超声心动图诊断的28例缺血性脑卒中患者进行PFO检测，分析不同卵圆孔特点下经颅多普勒超声微泡实验对PFO诊断检出率的变化。结果28例患者中，经颅多普勒超声微泡实验在平静呼吸状态下对PFO检出20例(71.43%)，配合Valsalva动作后检出24例(85.71%)。卵圆孔大小及开放状态与PFO的检出率无关(P>0.05)。结论经颅多普勒超声微泡实验对脑梗死患者的PFO的诊断具有较高敏感性，配合Valsalva动作可以提高诊断敏感性，可以作为PFO的筛查手段。

Abstract: Objective To evaluate the effect of contrast-enhanced transcranial Doppler (c-TCD) for detection of patent foramen ovale (PFO) comparing to transesophageal echocardiography (TEE). Methods 28 ischemic stroke patients with PFO detected with TEE were evaluated with TCD bubble study at rest and under Valsalva maneuver (VM). Results PFO was identified in 20 cases (71.43%) at rest by TCD bubble study. When VM was performed, PFO was detected in 24 cases (85.71%). There was no relevant in sensitivity of c-TCD with PFO size (P>0.05). Conclusion c-TCD is an excellent method for PFO identification with high sensibility while under VM. C-TCD can be used as a screening method for suspected PFO in patients with stroke test before TEE.
