摘要

右至左分流(RLS)与慢性过度通气综合征(CHVS)的关系尚未见报道。我们评估了CHVS患者的RLS患病率。CHVS患者和25名健康对照(CG)被纳入研究。血管性RLS诊断采用对比TCD。25例CHVS患者中，16例(64%)发生RLS, 3例(12%)发生CG。10例CHVS患者TEE确诊为PFO(40%)， 2例CHVS确诊为CG(8%)。2例(10%)CHVS患者在胸部CT上发现肺AVM，而CG未发现。CHVS患者的RLS和PFO患病率明显高于健康人。

An increased frequency of right-to-left shunt in patients with chronic hyperventilation syndrome

Relation of right-to-left shunt (RLS) with chronic hyperventilation syndrome (CHVS) has not been previously reported. We evaluated the prevalence of RLS in patients with CHVS. Patients with CHVS and 25 healthy controls (CG) were recruited into the study. Vascular RLS was diagnosed using contrast TCD. Of 25 subjects with CHVS, 16 (64%) had RLS vs 3 from CG (12%). TEE confirmed PFO in 10 patients with CHVS (40%) vs 2 from CG (8%). Pulmonary AVM was found in chest CT in 2 patients (10%) with CHVS and none from CG. The prevalence of RLS and PFO in patients with CHVS was significantly higher than in healthy subjects.
