A 73-year-old woman had undergone hemiarch replacement with primary entry resection for treating acute type A dissection 6 years ago. Postoperative computed tomography (CT) showed a patent false lumen (FL) in the aortic arch and a reentry tear in the right subclavian artery. The remaining aortic arch enlarged, which resulted in formation of a 55-mm-diameter aneurysm. We performed reentry occlusion using embolization with glue and coil. The patient’s clinical course after the procedure was uneventful, and subsequent CT showed that FL was thrombosed and had decreased in size.

Blunt aortic injures are rarely associated with minimal trauma. We present a 78-year-old man with an aortic pseudoaneurysm resulting from a simple vertebral compression fracture, which was conservatively managed. He was diagnosed with a compression fracture from a minor fall 10 days previously, and fortuitously he visited the hospital after which follow-up computed tomography (CT) for previous multiple aortic surgeries was performed. The enhanced CT revealed a pseudoaneurysm on the abdominal aorta, which was bleeding from a pinhole perforation. He was conservatively treated and follow-up CT 9 months later revealed that the pseudoaneurysm had disappeared.

A 54-year-old female with acute heart failure due to aortic regurgitation (AR) was admitted to our hospital. Following admission, her condition worsened progressively; thus, surgery was performed prematurely. During surgery, two dehiscences were visualized in the aortic valve commissure between the right and left cusps and the upper part of the left coronary artery ostium. However we scheduled aortic valve replacement (AVR) at first, we made the shift to perform the aortic root replacement for reinforcement of the aortic wall around the left coronary artery ostium. We describe a rare case of two dehiscences at the aortic root, which is the first report.
