Targeting fenestrations in an aortic aneurysm secondary to chronic type A or B dissections: a case series.

Using entry and re-entry analysis we report a simple technique designed to solely manage the fenestrations in an aortic aneurysm caused by chronic type A or B dissections. With meticulous computed tomography mapping of each fenestration, endovascular management can be customized to those areas only. Several cases are presented using this selective approach resulting in durable thrombosis of the false lumen.

We report the case of a 69-year-old woman with Marfan syndrome and a history of multiple thoracic aortic surgeries and a coexisting dissection of her abdominal aorta. She had presented with a ruptured para-anastomotic thoracic aortic aneurysm due to an infected graft. She was treated with two parallel Nellix endografts that were placed in the true and false lumens.

The use of an inner branch endograft for the treatment of failed chimney endovascular aortic repair.

The chimney endovascular aortic repair technique is an established option for the treatment of juxtarenal aortic aneurysms. Failure of this repair represents a major surgical challenge. We report the case of a patient treated previously with chimney endovascular aortic repair (for a juxtarenal aortic aneurysm), who had developed a large type IA endoleak.

Assessment of blood distribution in response to post-surgical steal syndrome: A novel technique based on Thermo-Anatomical Segmentation.

The distal ischemic steal syndrome (ISS) is a complication following the construction of an arteriovenous (A-V) access for hemodialysis. The ability to non-invasively monitor changes in skin microcirculation improves both the diagnosis and treatment of vascular diseases. In this study, we propose a novel technique for evaluating the palms' blood distribution following arteriovenous access, based on thermal imaging.
