Transient renovascular hypertension in childhood
European Journal of Pediatrics
|February 1, 1984
Summary
Severe renovascular hypertension in young children can be effectively managed with aggressive medical treatment. This approach allowed for normal growth and resolution of hypertension, avoiding early surgery.
Area of Science:
- Pediatric Nephrology
- Pediatric Cardiology
- Vascular Medicine
Background:
- Renovascular hypertension in children presents significant management challenges.
- Surgical intervention is often deferred in very young patients due to associated risks.
Observation:
- Two pediatric patients, aged 18 and 30 months, were diagnosed with severe renovascular hypertension.
- Initial treatment focused on aggressive medical management to control blood pressure and prevent complications.
Findings:
- The medical management successfully controlled hypertension and reversed its adverse effects in both children.
- Long-term follow-up demonstrated that both patients achieved normal growth and renal function.
- At ages 9 and 12, both children were normotensive and had discontinued all antihypertensive medications.
Implications:
- Aggressive medical therapy is a viable and effective alternative to early surgical intervention for pediatric renovascular hypertension.
- Successful non-surgical management can lead to long-term normalization of blood pressure, growth, and renal function in affected children.
- This approach may improve the overall prognosis and quality of life for children with this condition.

Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
Antihypertensive Drugs: Potassium-Sparing Diuretics
Liddle syndrome is a genetically inherited form of hypertension characterized by the overactivity of epithelial sodium channels in the nephron, the functional unit of the kidney. This heightened activity leads to increased sodium reabsorption and excessive excretion of potassium. To counteract this, potassium-sparing diuretics such as amiloride are used. They function by blocking these sodium channels, thereby reducing the influx of sodium into the epithelial cells and minimizing the loss of...
Hypertension I: Introduction
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
Hypertension II: Pathophysiology
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
Hypertension III: Clinical Manifestations and Diagnostic Studies
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
Acute Kidney Injury II: Pathophysiology
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
