(A,B) Duplex scan demonstrate a high flow aneurysm within a proximal jejunal branch of the superior mesenteric artery. This measures 15 x 23 mm in diameter and contains only a small volume of mural thrombus. Prominent inflow and outflow vessels are identified.

A mesenteric arterial Duplex scan demonstrated a high flow aneurysm within a proximal jejunal branch of the SMA, measuring 15 x 23 mm (antero-posterior [AP] x transverse [TV]) (Fig. 1A,B), and was followed by a computed tomography (CT) angiogram for work-up prior to any intervention.
(A) Angiogram of the superior mesenteric vessel demonstrating the jejunal branch pseudoaneurysm identified by the contrast blush. The proximal superior mesenteric vessel; middle colic artery; ileocolic-right colic trunk; jejunal branch pseudoaneurysm; and jejunal arterial branch. (B) Angiogram post-pseudoaneurysm coiling showing no contrast blush.

Tokyo, Japan) was inserted into the Hinck catheter using a coaxial technique up to the jejunal aneurysmal sac, which was well visualised (Fig. 2A). The pseudoaneurysm and any branches feeding the aneurysm were coiled using an AZURCX and AZUR Framing Coil (Terumo Medical Corp.) (Fig. 2B).
Duplex scan of the mesenteric vessel demonstrating a normal flow in superior mesenteric artery (SMA) proximally and distally. Embolisation material noted in SMA approximately 7 cm distal to the origin. There is no flow within this region to suggest recurrence of aneurysm.
