Background: A 64-year-old woman presented with dilatation of the distal aortic arch secondary to chronic type B aortic dissection.
Case Report: The patient underwent fenestrated thoracic endovascular aortic repair (TEVAR) for closure of the entry site, and reconstruction of the left subclavian artery with a covered stent. On the 40th postoperative day, a retrograde type A aortic dissection (RTAD) was observed on computed tomography and she underwent emergency surgery. The entry tear, related to the proximal bare metal stent, was located in front of the aortic arch. A partial aortic arch replacement was performed.
Conclusion: Consideration of the risk factors of RTAD is important when performing TEVAR.

Background: Acute type A aortic dissection (AAD) and acute type A intramural hematoma (AIMH) are life-threatening conditions with high mortality rates, and prognostic indicators are critical for guiding urgent treatment decisions. We assessed the prognostic significance of admission D-dimer levels in patients with AAD and AIMH.
Methods And Results: The prospective, multicenter, observational study in China recruited participants from 2013 to 2019.

Purpose: Stanford Type B Aortic Dissection (TBAD), a critical aortic disease, has exhibited stable mortality rates over the past decade. However, diagnostic approaches for TBAD during routine health check-ups are currently lacking. This study focused on developing a model to improve the diagnosis in a population.

Type B aortic dissection (TBAD) represents a serious medical emergency with up to a 50% associated 5-year mortality caused by thoracic aorta, dissection-associated aneurysmal (DAA) degeneration, and rupture. Unfortunately, conventional size-related diagnostic methods cannot distinguish high-risk DAAs that benefit from surgical intervention from stable DAAs. Our goal is to use DAA stiffness measured with magnetic resonance elastography (MRE) as a biomarker to distinguish high-risk DAAs from stable DAAs.

We report a case of mesenteric ischemia after thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection performed at a different institution. Computed tomography angiography findings indicated that the previous TEVAR had been deployed distally into the false lumen. To mitigate this, a large fenestration was created between the false lumen and true lumen.

Recent studies have attempted to characterize the layer-specific mechanical and microstructural properties of the aortic tissues in either normal or pathological state to understand its structural-mechanical property relationships. However, layer-specific tissue mechanics and compositions of normal and dissected ascending aortas have not been thoroughly compared with a statistical conclusion obtained. Eighteen ascending aortic specimens were harvested from 13 patients with type A aortic dissection and 5 donors without aortic diseases, with each specimen further excised to obtain three tissue samples including an intact wall, an intima-media layer and an adventitia layer.
