Renal artery dissection: a complication of catheter arteriography.
Renal artery dissection is a rare complication of catheter arteriography. Predisposing factors include atherosclerosis and fibromuscular dysplasia. Optimum management requires aortographic documentation of the extent of vascular obstruction. Dissections causing incomplete obstruction of blood flow can be treated with systemic anticoagulation to prevent downstream thrombosis and should be followed with serial isotope blood flow studies and LDH measurements. Dissection causing complete vascular obstruction usually requires immediate surgery, although spontaneous reestablishment of flow may occur. The 3 patients discussed illustrate a spectrum of findings, including the acute development of renovascular hypertension.
