To report our early experience with endovascular repair of acute non-A-non-B aortic dissections using chimney grafts to preserve blood flow to a left common carotid artery (LCCA) located in the proximal landing zone. ⋯ In short-term follow-up, TEVAR combined with the chimney technique seems promising for aortic dissections that involve the aortic arch with inadequate proximal sealing zones. More cases and long-term results are needed to evaluate the safety and efficiency of this alternative endovascular technique.

To analyze the impact of stent-graft design on the outcome of endovascular repair of acute traumatic thoracic aortic transection. ⋯ Enhanced stent-graft conformability and more accurate delivery systems have significantly decreased the morbidity of endovascular repair of acute traumatic transection of the thoracic aorta. The increasing clinical experience may also have contributed to improved results.

To assess the reproducibility of estimating biomechanical parameters of abdominal aortic aneurysms (AAA) based on finite element (FE) computations derived from a commercially available, semiautomatic vascular analyzer that reconstructs computed tomographic angiography (CTA) data into FE models. ⋯ The reproducibility of volume and maximum diameter measurements in infrarenal AAAs with FE analysis is high. With the model used in this semiautomatic reconstruction software, wall stress analysis can be achieved with high agreement among observers and in serial measurements by a single observer.
