Nombres alternativos:

Hipertensión renal; Hipertensión de tipo renovascular

Causas, incidencia y factores de riesgo:

Cuando las arterias renales se estrechan, fluye menos sangre hacia los riñones. Los riñones responden de manera errónea como si la presión arterial del paciente estuviera baja y liberan hormonas que le ordenan al cuerpo retener sal y agua, lo cual causa un aumento en la presión arterial.

Muchas enfermedades diferentes pueden causar estrechamiento de las arterias renales, siendo la estenosis de la arteria renal una de las más comunes.
