Purpose: To evaluate the impact of two-dimensional and three-dimensional preoperative morphologic features analyzed on computed tomography (CT) angiography on midterm outcome in patients with abdominal aortic aneurysms (AAAs) treated with endovascular aneurysm repair (EVAR).
Materials And Methods: A retrospective analysis was conducted using a prospectively collected database. Morphologic features considered as potentially influencing outcomes were maximum aortic diameter, thrombus area, overall aneurysm volume, and intrasac thrombus volume. Outcome measures were all perioperative and midterm AAA-related reinterventions and all-cause mortality.
Results: Investigators reviewed 191 preoperative CT angiography scans. Mean maximum aortic diameter was 58 mm; thrombus area, 49.6%; aortic volume, 159.36 cm(3); and thrombus volume, 58.6%. Technical success was achieved in all cases. No reintervention was required in the perioperative period, and there was no perioperative mortality. At a mean follow-up of 32 months ± 16.8 (range, 3-66 mo), mortality rate was 9.4%, AAA-related death was 0, and reintervention rate was 8.9%. Causes of reintervention included type I endoleak (n = 3 [1.6%]), type II endoleak (n = 7 [3.7%]), type III endoleak (n = 1 [0.5%]), endograft limb thrombosis (n = 4 [2.1%]), and access vessel thrombosis (n = 2; 1%). Greater thrombus area (> 60%) and thrombus volume (> 59%) were predictors for reintervention (P = .005 and P = .0034). Greater maximum aortic diameter (> 59 mm) and aortic volume (> 159 cm(3)) were related to higher reintervention rate without statistical significance (P = .62 and P = .12). Aortic volume was a predictor of any adverse event, reintervention, and all-cause mortality after EVAR (P = .03).
Conclusions: Thrombus area and volume are related to higher rates of reintervention. Maximum aortic diameter was related to a higher reintervention rate, but this was not significant.

Background: Past studies have reported that vertebrobasilar dolichoectasia (VBD) patients may develop similar arteriopathies other than the vertebrobasilar system. However, the details of these VBD-related arteriopathies are still unclear.
Methods: We retrospectively enrolled patients diagnosed with VBD at two stroke centers in Japan between January 2012 and December 2023.
The Impact of the COVID-19 Public Health Crisis on the Surgical Management of Abdominal Aortic Aneurysm Rupture.

Objectives: The COVID-19 epidemic introduced significant systems- and disease-based uncertainty into Abdominal Aortic Aneurysm (AAA) rupture management. The goal of this work was to evaluate whether short-term AAA rupture outcomes during COVID-19 were comparable to pre-COVID era outcomes and to explore the impact of COVID status and COVID era healthcare systems restrictions on AAA rupture outcomes.
Methods: The Vascular Quality Initiative (VQI) database was queried for all ruptured AAAs that underwent intervention from January 1, 2019 to August 31, 2022.

Hemodynamic stabilization is crucial in managing acute cardiac events, where compromised blood flow can lead to severe complications and increased mortality. Conditions like decompensated heart failure (HF) and cardiogenic shock require rapid and effective hemodynamic support. Current mechanical assistive devices, such as intra-aortic balloon pumps (IABP) and extracorporeal membrane oxygenation (ECMO), offer temporary stabilization but are limited to short-term use due to risks associated with prolonged blood contact.

Background: In patients with diabetes mellitus (DM), vascular endothelial dysfunction (VED) is the main reason for impaired life expectancy. Melatonin (MEL) demonstrates wide-ranging effects across various organs and exhibits pleiotropic characteristics. The current study aims to investigate the modulatory roles of MEL vascular response to angiotensin II (Ang II) and its receptors including angiotensin type 1 receptor (AT-1 R) and angiotensin type 2 receptor (AT-2 R) in isolated thoracic aorta of non-diabetes (non-DM) and diabetes (DM) rats.

It remains difficult to predict which patients will require great arterial reintervention.
Objective: We aimed to characterize hemodynamics within the great arteries using 4D flow MRI in patients with d-TGA after the arterial switch operation.
