Renal artery dissection after angiographic evaluation of lower extremities.
We describe a case of renovascular hypertension that was caused by renal artery dissection after an angiographic evaluation of the lower extremities. Retention of contrast medium in the affected kidney even 1 day after the procedure caused us to suspect renal artery dissection. Magnetic resonance angiography revealed irregular streaks in the lumen of the affected artery, a sign of dissection. Treatment by a transluminal angioplasty with stent insertion improved renal function and reduced systemic blood pressure with normalization of plasma renin activity. In patients whose systemic blood pressure increases suddenly after any conceivable physical traction on the abdominal aorta, evaluation of the renal arteries should be considered. Appropriate endovascular treatment can preserve renal function and reduce systemic blood pressure.
