Spontaneous arteriovenous fistula resulting from HIV arteritis.
Arteriovenous fistulas (AVFs) are uncommon and usually follow trauma or preceding arterial catheterization or puncture. Spontaneous AVFs are rare. A case of spontaneous AVF of the superficial femoral artery and vein in an HIV-infected patient is presented. Histologic examination of the artery showed features similar to those seen in HIV-related large-vessel aneurysms. It would appear that spontaneous AVF are part of the spectrum of macrovascular arteritis related to HIV infection.
