A case of pseudoaneurysm of the marginal artery of Drummond post-open abdominal aortic aneurysm (AAA) repair.

We present the first published account of a pseudoaneurysm of the Marginal artery of Drummond (MAoD) following an emergency open surgical repair of an inflammatory abdominal aortic aneurysm, in which the inferior mesenteric artery was ligated. This was hypothesized to be an iatrogenic injury secondary to retraction of the colonic mesentery during dissection of the aneurysm neck. The risk of pseudoaneurysm growth and rupture versus bowel ischaemia were evaluated in the post-operative phase. Ultimately, the patient underwent successful interventional embolization of the MAoD with no signs of bowel ischaemia post-intervention.
