Mechanical aortic valve may no longer be a contraindication to inner branch aortic arch endografts.

Objectives: The presence of a mechanical aortic valve has been a contraindication to the use of an arch branch aortic endograft due to the risk of damaging the valve, resulting in acute aortic regurgitation, or a trapped endograft.

Methods: We present a 67-year-old woman, with a background of Marfan's syndrome and a previous Bentall's procedure, who presented with a symptomatic enlarging aortic arch and descending thoracic aortic aneurysm, with a type 1A endoleak.

Results: Using an inner branch arch endograft (Cook Medical, Bloomington, Indiana), the nose cone of the delivery system was passed laterally through the semi-circular aperture of the mechanical aortic valve to facilitate deployment just distal to the coronary buttons.

Novel modification of a branched arch endograft with a retrograde left common carotid branch for acute pseudoaneurysm post type A repair.

Objective: Pseudoaneurysm formation post type A aortic dissection repair is rare. Revision surgical repair is challenging, with a risk of death from haemorrhage.

Methods: We present a 56-year-old man who presented with a rapidly enlarging distal ascending aortic anastomotic pseudoaneurysm following a recent ascending and hemiarch replacement for acute type A aortic dissection.

An open approach to a ruptured common iliac artery aneurysm with resultant ilio-iliac arteriovenous fistula.

Objective: Presentations of a spontaneous ilio-iliac arteriovenous fistula are considered a rare occurrence and warrant urgent intervention. They are usually a result following trauma, previous surgery or uncommonly from a ruptured aneurysm.

Method: We describe a case of a patient presenting with general malaise who examined to have a pulsatile abdominal mass with an associated bruit.

Outcome of acute hospital admission for non-specific low back pain: what is the role of MRI?

Background: Low back pain is a common worldwide condition, affecting most people during their lifetime. Various imaging modalities are being used to assist clinicians in diagnosing and thus, aid in formulating a suitable management plan. Extensive research has been carried out in assessing this condition due to its high prevalence, with many guidelines published internationally.
