Abstract
Objective

To present 2 cases with unilateral renal artery occlusion after blunt trauma conservatively treated and review, in the literature, the role of age as a prognostic factor for the development of hypertension.

Material and methods

A 14 and 12 y/o male and female passengers, who were unrestrained in the back seat of a car, were involved in different motor vehicle accidents. Both remained in the seat and arrived at the Pediatric Emergency Department with normal vital signs. Computerized tomography scans showed unenhancing kidneys. Conservative management was advocated.

Results

After 38 and 36 months follow-up, respectively, normal renal function and arterial pressure. We found only 7 cases in the literature where age ≤16 was reported and treatment was conservative. Nine in total, hypertension developed in 2(22%).

Conclusions

No conclusion could be made with such a small sample. There is enough evidence in the literature supporting conservative management at all ages.

Resumen
Objetivo

Presentar 2 casos de oclusión de la arteria renal unilateral secundario a trauma abdominal contuso manejados conservadoramente y revisar, en la literatura, el rol de la edad como factor predictor en el desarrollo de hipertensión.

Material y métodos

Masculino y femenina de 14 y 12 años, respectivamente, participaron en accidentes automovilísticos diferentes sin portar cinturón de seguridad permaneciendo en el asiento. Ambos arribaron a urgencias pediatría con signos vitales normales. Ambas tomografías revelaron riñón sin captación de contraste. El manejo fue conservador.

Resultados

Posterior a 38 y 36 meses de seguimiento, respectivamente, ninguno presenta hipertensión o daño en la función renal. Encontramos solo 7 casos, en la literatura, con edad ≤16 manejados conservadoramente. En total 9, existió hipertensión en 2 (22%).

Conclusiones

No se puede llegar a una conclusión contundente con una muestra tan pequeña aunque existe evidencia suficiente que soporta el manejo conservador del padecimiento a cualquier edad.
