Article Abstract
Background: After proximal aortic surgery, total arch replacement (TAR) may again be needed because of recurrent dissection or aneurysm. This paper analyzed the relevant data of this technology with hopes of improving cognition and treatment.
Methods: There were a total of 60 eligible cases of secondary TAR after proximal aortic surgery in our center from 2010 to 2020. The primary surgical procedures included aortic valve replacement (AVR), ascending aortic replacement, Bentall, hemi-arch replacement, and thoracic endovascular aortic repair (TEVAR). The data were analyzed using the IBM SPSS Statistics 23.0 for Windows™ and presented as the mean ± standard deviations and direct frequencies, as appropriate.
Results: The interval between two operations was 44.8±53.6 months, 24 cases (40%) underwent emergency operation, the recurrence of type A dissection included 51 cases, accounting for 85% of the causes of total arch re-replacement. In the second surgical procedures, the ascending + TAR + stented elephant trunk (SET) implantation accounted for 75.0%. The overall surgical success rate was 98.3%. Postoperative respiratory complications were the most common, including infection, pneumothorax and hemothorax in 21 cases (35.6%). The second most common complication was acute kidney injury (AKI) in six cases (10.2%), and neurological complications took place in three cases (5.1%). The 30-day mortality rate was 15.3% and the 1-, 3- and 5-year survival rates were 96.0%, 84.0%, and 76.0%, respectively.
Conclusions: The recurrence of dissection is the main cause of TAR after proximal aortic surgery, followed by aneurysm and the resurgical criteria for aneurysm needs to be unified. In addition to TAR, SET also is widely used. Despite high early mortality, its long-term prognosis is acceptable.

Objective: This study aimed to evaluate treatment indications, compare therapeutic approaches, and assess outcomes in patients with infrarenal penetrating aortic ulcers (iPAUs).
Methods: This was a retrospective, multicentre, observational study of patients with iPAUs treated between January 2018 and December 2022 across 12 European centres. Treatment strategies included open surgical repair (OSR) and endovascular techniques, including balloon expandable stent grafts (BESGs), covered endovascular reconstruction of the aortic bifurcation (CERAB), and endovascular aortic repair (EVAR) using bifurcated or tube grafts.

Background: To investigate whether endovascular repair of ruptured abdominal aortic aneurysm (RAAA), performed whenever anatomically feasible, would be superior in a real-world registry.
Methods: Retrospective analysis of consecutive RAAA patients treated at the emergency department of a single hospital from January 2011 to December 2023, after implementation of protocol-based care. The variables of interest were hemodynamic stability, proximal neck length, and type of intervention.

Endovascular surgeries generally rely on push-based catheters and guidewires, which require significant training to master and can still result in high stress being exerted on the anatomy, especially in tortuous paths. Because these procedures are so technically challenging to perform, many patients have limited access to high-quality treatment. Although various robotic systems have been developed to enhance navigation capabilities, they can also apply high stresses due to sliding against the vascular walls, impeding movement and raising the risk of vascular damage.

Objective: Sex specific anatomical differences may contribute to observed disparities in outcomes and suitability for endovascular aneurysm repair (EVAR) between men and women with abdominal aortic aneurysms (AAAs). This study aimed to assess these differences using fully automated volume segmentation (FAVS) and explore implications for EVAR suitability.
Methods: This was a retrospective, multicentre cohort study of patients undergoing elective AAA repair between 2013 and 2023 in three UK tertiary centres.

Introduction: The natural history of bicuspid aortic valve (BAV) remains inadequately characterized, leaving uncertainties regarding whether associated aortic dilatation arises from an inherent susceptibility or primarily results from altered flow dynamics across the aortic valve. We aimed to describe the evolution of valve function and aortic dilatation at preschool-age in children diagnosed with BAV neonatally.
Methods: The population study, Copenhagen Baby Heart Study (n >25,000) performed in 2016-2018, diagnosed 196 newborns (0.
