چکیده

Hypertensive patients presenting at the extremes of age may have a secondary cause of hypertension. Congenital arteriovenous malformation (AVM) and acquired arteriovenous fistula (AVF) are rare causes of secondary hypertension w1–10x. Acquired AVFs tend to be single linear connecting vessels and comprise 70–80% of renal arteriovenous abnormalities and usually result from trauma, biopsy, surgery, malignancy, or inflammation w1,3x. Congenital AVM is described as crisoid with a knotted, tortuous appearance of numerous feeding vessels, and multiple interconnecting fistulas; however, a variant called ‘angiomatous’ AVM has a single vessel feeding multiple small interconnecting vessels w1,4x. We present a case of hypertension secondary to congenital AVM managed by superselective embolization and a brief review of the literature.

Color Doppler ultrasonography, multislice CT angiography, and DSA are important tools for making the diagnosis. We describe the case of a 62-year-old man with renal arteriovenous malformation who presented with gross hematuria.
