Concomitant Pseudoaneurysm and Arteriovenous Fistula Formation of Brachial

Concomitant pseudoaneurysm and arteriovenous (AV) fistula formation of brachial artery after a penetratinginjury has been rarely reported. False aneurysms of peripheral arteries are very rare. It is usually of infectious, post-traumatic or of iatrogenic etiology. In most cases, these are the result of penetrating injuries such as gunshot or stabwounds and iatrogenic arterial injuries. Brachial artery is not a common site for peripheral artery aneurysms. Its associationwith fistula formation with adjacent vein makes this a rare case. This case was diagnosed on colour duplex ultrasound andconfirmed on subtraction angiography.
