Though stenoses of the descending aorta and its branches are seen with congenital anomalies or systemic inflammation, occlusion of the descending aorta is extremely rare. A patient with an occluded hypoplastic descending thoracic aorta required re-operation because of graft failure between the descending thoracic aorta and the infrarenal abdominal aorta. The etiology of the aortic occlusion in this case is unknown, but inflammation, such as Takayasu disease, is speculated.

Introduction: Management of patients with large aortic arch aneurysms who are considered high risk for frozen elephant trunk technique have been challenging, especially when they have a dilated ascending aorta (AA) that precludes total endovascular branched repair (arch BEVAR). A viable option in our armamentarium is wrapping of the AA (AW), and zone 0 Ishimaru TEVAR.
Methods: Retrospective analysis of our aortic database from 2013 to 2024 to select high-risk patients with aortic arch aneurysm that had an AW and TEVAR.

Transaortic endarterectomy (TE) is an effective and durable method of restoring patency in the aorta afflicted with atherosclerotic disease, which most commonly affects the infrarenal aorta and common iliac artery. When the suprarenal aorta is involved, the disease is usually confined to the orifices of the visceral vessels without obstruction of the aortic lumen. In rare cases, dense, calcified, exophytic, and amorphous lesions causing severe luminal obstruction, termed coral reef atherosclerosis (CRA) of the suprarenal aorta, may occur.

A 55-year-old woman with non-small cell lung carcinoma complained of epigastric pain, bloating, anorexia and postprandial nausea and vomiting over a five-year period. An upper gastrointestinal pan-glucosamine contrast examination revealed a distinctive large, hook-shaped, ptotic gastric lumen with normal motility. The contrast agent demonstrated an abnormal round-trip flow anterior to the spine at the duodenal level, with pooling and gradual passage through this region in strands after prolonged retention.

Aims: Aortic wall stiffening in ascending thoracic aortic aneurysm (aTAA) is common. However, the spatial and temporal relationships between stiffness, aortic size, and growth in aTAA remain unclear.
Methods And Results: In this single-centre retrospective study, we utilized vascular deformation mapping to extract multi-directional aortic motion, aortic distensibility, and aortic growth in a multi-planar fashion from multi-phasic ECG-gated computed tomography angiograms.
The aortic-vertebral distance is more associated with axial plane deformities than coronal and sagittal deformities in idiopathic scoliosis patients of Lenke types I and II.

Purpose: Although idiopathic scoliosis is a common three-dimensional deformity, there is a lack of studies evaluating the associations between the aortic-vertebral distance (AVD) and spinal deformities in all planes. The study therefore aimed to evaluate how the coronal and sagittal curvature, vertebral rotation and aortic-vertebral angle (AVA) affect the AVD in idiopathic scoliosis.
Methods: The AVD, AVA, vertebral rotation and curve angles were measured on preoperative magnetic resonance imaging and radiographs in 46 patients who underwent posterior spinal fusion with pedicle screw instrumentation for idiopathic scoliosis Lenke types 1 and 2.
