How to do it: a modified transabdominal wall approach for direct external iliac artery access during endovascular thoracic aneurysm repair.

We describe the combined application of a transabdominal wall sheath tunnel, 'pre-close' purse-string sutures and manual external support of the iliac artery to facilitate introduction of an 18F sheath for endovascular exclusion of a 6-cm thoracic aortic aneurysm.

Inner-Branched Endografts for the Treatment of Aortic Arch Aneurysms After Open Ascending Aortic Replacement for Type A Dissection.

Background: The development of a postdissection aortic arch aneurysm after open ascending aortic replacement for type A dissection places the patient at increased risk for an open operation due to the need for redo sternotomy and total arch replacement. We conducted a computed tomography-based feasibility study to assess what proportion of these patients would be anatomically suitable for branched endograft repair of an arch aneurysm. We also aimed to identify ways to tailor the index operation to increase suitability for future endovascular repair.
