Figure 1. Dissection of the common femoral artery, characterised by contrast holdup post-injection, due to contrast staying in one of the layers between arterial tunica intima and tunica adventitia Very rarely, the needle can displace following successful intraluminal cannulation. If the wire does not easily pass, it is important never to force it. Such an event occurred on this occasion. Following an unsuccessful attempt to pass the wire, contrast was injected through the needle. This demonstrated dissection of the common femoral artery, characterised by contrast holdup post-injection, due to contrast staying in one of the layers between art
