The present study included 84 patients with ischemic stroke of known and unknown etiology. The risk of paradoxical embolism (PE) was evaluated using contrast transthoracic echocardiography, contrast transcranial Doppler monitoring, and transoesophagal echocardiography. The majority 64%) of the patients with strokes of known etiology were found to be predisposed to PE because they had the patent interatrial foramen (PIF) and pulmonary shunt (51 and 13 respectively). PIF was of small functional and anatomical size. Predisposition to PE in most patients with cryptogenic stroke (94%) was due to the presence of PIF (in 88%) and was often the sole cause of the stroke. These patients frequently had the shunt of a large functional size.
本研究纳入了84例病因已知和未知的缺血性中风患者。采用经胸超声心动图造影、经颅多普勒超声造影监测和经食管超声心动图评估反常栓塞（PE）的风险。在病因已知的中风患者中，大多数（64%）被发现易患PE，因为他们存在房间隔卵圆孔未闭（PIF）和肺分流（分别为51例和13例）。PIF在功能和解剖学上的尺寸较小。大多数隐源性中风患者（94%）易患PE是由于存在PIF（88%），且往往是中风的唯一原因。这些患者经常有较大功能尺寸的分流。
