Intense impact of IL-1β expressing inflammatory macrophages in acute aortic dissection.

There is no treatment for acute aortic dissection (AAD) targeting inflammatory cells. We aimed to identify the new therapeutic targets associated with inflammatory cells. We characterized the specific distribution of myeloid cells of both human type A AAD samples and a murine AAD model generated using angiotensin II (ANGII) and β-aminopropionitrile (BAPN) by single-cell RNA sequencing (scRNA-seq).

Anterolateral thoracotomy with partial sternotomy: a feasible approach for treating the complex pathology of the aortic arch.

Objectives: Our goal was to review our surgical experiences in patients with complex pathologies of the aortic arch who have undergone anterolateral thoracotomy with a partial sternotomy (ALPS).

Methods: From October 2019 to November 2023, a total of 23 patients underwent one-stage repairs of complex pathologies of the aortic arch through the ALPS approach. The mean age was 61.

Open Conversion with Explantation of Stent Grafts After Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm.

Background: Although endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is widely used worldwide, the fact that it is associated with increased rates of reintervention has been considered a problem. This study aimed to analyze the outcomes of primary open AAA repair and open conversion with explantation of stent grafts after EVAR.

Methods: In this retrospective study, we enrolled 1,120 patients (open repair, n = 664; EVAR, n = 456) who underwent AAA repair at Kobe University from 1999 to 2019.

Japanese single-center experience of abdominal aortic aneurysm repair over 20 years: should open or endovascular aneurysm repair be performed first?

Purpose: The present study analyzed the outcomes of our experience with abdominal aortic aneurysm (AAA) repair over 20 years using endovascular aortic repair (EVAR) with commercially available devices or open aortic repair (OAR) and reviewed our surgical strategy for AAA.

Methods: From 1999 to 2019, 1077 patients (659 OAR, 418 EVAR) underwent AAA repair. The OAR and EVAR groups were compared retrospectively, and a propensity matching analysis was performed.

Early and late outcomes of type A acute aortic dissection with common carotid artery involvement.

Objective: The relationship between common carotid artery (CCA) involvement in acute type A aortic dissection (ATAAD) and postoperative outcomes remains unclear. We investigated outcomes and described our current advanced strategy.

Methods: Of 492 patients who underwent surgical repair for ATAAD between September 1999 and February 2021, CCA involvement was identified in 114.

[Does Surgeons' Experience Affect the Surgical Outcomes of Total Arch Replacement?].

Objectives: Total arch replacement( TAR) is used to be a complicated and quite invasive aortic procedure. To perform TAR safely and effectively under all circumstances, we have constructed standardization of the procedures of TAR. The aim of this study is to analyze the impact of surgeons' experience on surgical outcome of TAR to evaluate our standardization.

A rare case of idiopathic chronic expanding pericardial hematoma presenting as pericardial tamponade: a case report and literature review.

Chronic expanding pericardial hematoma is a very rare disease that occurs after open-heart surgery. We report successful surgical treatment of a rare case of chronic expanding pericardial hematoma that developed into a large mass and presented as pericardial tamponade without apparent cause. An 82-year-old woman with no history of cardiac surgery, chest trauma, or epicardial injury presented with a 3-year history of progressive exertional dyspnea.
