We report a case of fetal systemic hypertension. This occurred in an ex-donor twin soon after coagulation of chorionic vessels and amniodrainage performed for severe twin-twin transfusion syndrome during the 2nd trimester of pregnancy. Systemic hypertension was suspected because of a high systolic velocity through the tricuspid valve, and Bernoulli's equation was used to estimate the right intraventricular pressure. As both pulmonary arteries and ductus arteriosus were normal, the pressure in the aorta was considered to be equal to that in the right ventricle (60 mm Hg). Fetal systemic hypertension could have happened either because of a dramatic increase in placental resistances in the territory of the ex-donor twin or by reversal of the fetofetal transfusion pathological process.
我们报告一例胎儿系统性高血压病例。该病例发生在一名前供体双胎中，在妊娠中期因严重双胎输血综合征进行绒毛膜血管凝固和羊水引流后不久出现。由于通过三尖瓣的收缩期速度较高，怀疑存在系统性高血压，并使用伯努利方程估计右心室内压力。由于肺动脉和动脉导管均正常，因此认为主动脉压力与右心室压力相等（60mmHg）。胎儿系统性高血压可能是由于前供体双胎区域胎盘阻力急剧增加，或者是由于胎儿-胎儿输血病理过程的逆转所致。
