The Basic Lecture Course (BLC) held by U-40 (which is The Japanese Society for Cardiovascular Surgery Under-Forty) aims to improve the basic skills and knowledge of young cardiovascular surgeons. The aim of this report is to survey the strategies of total arch repair for thoracic aortic aneurysms focusing on differences in treatment between hospitals, and to share the results of this questionnaire investigation about this.

The transition to the new specialist certification system has progressed in cardiovascular surgery, enabling many surgeons to obtain specialist certification earlier than before. This study focuses on conditions that are particularly easy to overlook factors in the application process, namely academic activities, surgical experience, and Off-the-Job Training (OJT). This report summarizes these changes to facilitate efficient specialist certification applications for trainees.

Objective: We examined complications of the downstream aorta after the frozen elephant trunk (FET) procedure. Methods: Complications were diagnosed in eight patients: true aneurysm alone in five patients; type A aortic dissection in two patients; and both true aneurysm and type B aortic dissection in one patient. Results: Elective surgery was performed in seven patients. Five patients received a Matsui-Kitamura stent graft (MKS) and three patients received a J Graft Open Stent Graft (JGOSG). The FET procedure was successfully applied in all cases. Over the long term, dilatation of the descending thoracic aorta (dTA) alone was identified in two patients and dilatation of the dTA and migration was identified in three patients using the MKS. Complications of graft kinking and migration were seen in one patient and distal stent graft-induced new entry in two patients using the JGOSG. Thoracic aortic stent graft repair was successfully performed for complications in seven patients. Conclusion: For the improvement of clinical results, FET devices need to offer flexibility and appropriate radial force.
