[Surgical treatment of renovascular hypertension in children]
Insights
Renovascular hypertension in children, often caused by fibromuscular dysplasia, requires treatment. Surgical reconstruction, particularly aortorenal bypasses, offers substantial health improvements or cures for affected children.
Area of Science:
- Pediatric Nephrology
- Cardiovascular Surgery
- Vascular Biology
Background:
- Renovascular hypertension (RVH) accounts for 5-20% of pediatric hypertension cases.
- Idiopathic fibrous dysplasia and fibromuscular dysplasia are primary causes of pediatric RVH.
- Effective management is crucial for preventing long-term complications.
Observation:
- Surgical reconstruction techniques, including aortorenal bypasses with autologous grafts, are key interventions.
- Evaluation of 334 pediatric RVH cases from literature and 8 personal cases was performed.
- Outcomes were assessed using National Heart, Lung, and Blood Institute criteria.
Findings:
- Surgical management, especially arterial reconstruction, yields significant health improvements or cures in most pediatric patients.
- Conservative treatment and angioplasty are part of the management spectrum.
- Nephrectomy is reserved as a last resort.
Implications:
- Optimized surgical strategies can lead to better prognoses for children with renovascular hypertension.
- Further research into pathogenesis and refined surgical techniques is warranted.
- Early diagnosis and intervention are critical for successful outcomes in pediatric RVH.
Abstract:
The main reason for renovascular hypertension in children is ideopathic fibrous and fibromuscular displasia. The pathogenetic classification of the disease was worked out in 1971 by Harrison and McCormac. Of all cases of hypertension in children between 5 and 20% are of renovascular origin. The illness demands an absolute necessity for treatment. The concept of management of renovascular hypertension includes the conservative treatment as well as angioplasty and especially the surgical reconstruction of the arteries. Nephrectomy should be considered as the treatment of last resort. For the surgical reconstruction of arteries a variety of techniques are available. Aortorenal bypasses using autologous arterial or venous grafts are expecially suitable in surgical treatment of renovascular hypertension in children. Results given in literature of the management of 334 children with renovascular hypertension and 8 own cases were evaluated by us according to the criteria of the National Heart, Lung and Blood Institute. In the majority of surgical treated children a substantial improvement in the state of health, or cure, could be achieved.
