The outcomes and cost analysis of open repair and endovascular aneurysm repair for abdominal aortic aneurysms: a single-center experience in Japan.

Purpose: Japan has adopted its own reimbursement system, which differs from other countries in terms of its diagnostic procedure combination (DPC) methods. However, there are few reports on the cost analysis of open repair and endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms in Japan. We aimed to evaluate the long-term outcomes and cost-effectiveness of these two procedures.

Long-term results of the frozen elephant trunk technique in primary chronic type B aortic dissection.

Objectives: The aim of this study is to analyze long-term results of the total aortic arch replacement with the frozen elephant trunk technique for primary chronic type B aortic dissection.

Methods: Among 322 patients who had the frozen elephant trunk technique, 43 (13.4%) patients (median age, 64.

[Complete Disruption of the Left Main Bronchus Treated with Extracorporeal Membrane Oxygenation Support and Pneumonectomy].

A 60-year old woman, sandwiched between two boats was brought to our hospital with severe respiratory failure. She was in pre-shock and there was extensive cutaneous emphysema from the face to abdomen. She required respirator support and bilateral chest tubes for hemopneumothorax.

Left ventricular mass and valve performance after surgical and transcatheter aortic valve replacement: a single-center experience from Japan.

Background: There are few reports on the postoperative left ventricular mass (LVM), aortic valve area (AVA), and pressure gradient (PG) after surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) in Japan. We aimed to compare the postoperative LVM, AVA, stroke volume (SV), PG, and long-term outcomes between patients undergoing SAVR and TAVR procedures from single center in Japan.

Methods: This was a retrospective cohort study.

Impact of the Barthel Index Score and Prognosis on Patients Undergoing Transcatheter Aortic Valve Replacement and Surgical Aortic Valve Replacement.

Background: Few studies have compared the Barthel Index (BI) score and postoperative outcomes of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR). We aimed to examine the relationship between the BI score and postoperative outcomes in patients who underwent TAVR and SAVR.

Methods and results: The study included patients who underwent SAVR between January 2014 and December 2022 (n=293) and patients who underwent TAVR between January 2016 and December 2022 (n=312).
