Hyponatremic hypertensive syndrome is characterized by hypertension, hyponatremia, and hypokalemia due to unilateral renal artery stenosis. We herein report a 1-year-old hyponatremic hypertensive syndrome infant without persistent hypertension in the acute phase. On the ninth hospital day, his systolic and diastolic blood pressure increased up to 154-160 and 70-84 mmHg, respectively. Acute gastroenteritis and dehydration might transiently mask his hypertension. By percutaneous transluminal balloon angioplasty for right renal artery, his blood pressure finally normalized without antihypertensive drugs. We reviewed 23 previously reported pediatric patients with hyponatremic hypertensive syndrome under the age of 15 years. Including our patient, there are only three reports on hyponatremic hypertensive syndrome without persistent hypertension in the acute phase. Hyponatremic hypertensive syndrome is curable with proper diagnosis and timely intervention. Therefore, pediatricians should pay attention to the signs and symptoms associated with hyponatremic hypertensive syndrome, even if persistent hypertension was absent in the acute phase.
低钠血症性高血压综合征的特征是由于单侧肾动脉狭窄导致高血压、低钠血症和低钾血症。我们在此报告一名1岁的低钠血症性高血压综合征婴儿，急性期无持续性高血压。在住院第9天，他的收缩压和舒张压分别升至154 - 160 mmHg和70 - 84 mmHg。急性肠胃炎和脱水可能暂时掩盖了他的高血压。通过经皮腔内球囊血管成形术治疗右肾动脉，他的血压最终在未使用降压药物的情况下恢复正常。我们回顾了23例先前报道的15岁以下低钠血症性高血压综合征儿科患者。包括我们的患者在内，仅有3篇关于急性期无持续性高血压的低钠血症性高血压综合征的报道。低钠血症性高血压综合征通过正确诊断和及时干预是可治愈的。因此，儿科医生应注意与低钠血症性高血压综合征相关的体征和症状，即使急性期无持续性高血压。
