We here report the case of a 52-year old hypertensive, obese woman (BMI 32,46 kg/m) with a past history of smoking and without evidence-based risk factors of venous thromboembolism, hospitalized for left chest pain radiating to the dorsolumbar region associated with dyspnoea. Clinical examination on hopitalization showed left blood pressure 100/60 mmHg, tachycardia 100/min, oxygen desaturation index at 88% with the patient breathing ambient air, normal cardiopulmonary auscultation, peripheral pulses palpable and no symptoms of phlebitis of the lower limbs. The ECG showed right axis deviation, SQ pattern, right ventricular hypertrophy and right bundle branch block (A, B, C). The patient underwent emergency thoracic CT angiography objectifying aortic dissection from the origin of the aorta to the iliac bifurcation (Stanford A). Our patient received medical care based on blood pressure and heart rate control as well as on analgesics, with good evolution in the absence of surgical means.

Background: Recent studies show that hyperactivation of mTOR (mammalian target of rapamycin) signaling plays a causal role in the development of thoracic aortic aneurysm and dissection. Modulation of PP2A (protein phosphatase 2A) activity has been shown to be of significant therapeutic value. In light of the effects that PP2A can exert on the mTOR pathway, we hypothesized that PP2A activation by small-molecule activators of PP2A could mitigate AA progression in Marfan syndrome (MFS).

A 69-year-old man with chest pain was diagnosed with acute type B aortic dissection with the entry tear located at distal arch and a distal aortic arch aneurysm. Therefore, we performed debranching thoracic endovascular aortic repair 2 weeks after type B aortic dissection onset. First, the graft was anastomosed to bilateral axillary arteries.

Objective: To explore the anatomical and clinical factors that affect the radiographic exposure time in radial artery cerebral angiography and to establish a model.
Method: A total of 210 patients who underwent radial artery cerebral angiography at this center from September 2021 to May 2022 were selected, and their anatomical and clinical factors were analyzed to evaluate the correlation between these factors and the duration of radiographic exposure. A related neural network prediction model was established.

Background: This study aimed to investigate the demographics and to evaluate long-term outcomes of acute type A aortic dissection (ATAAD) in surgically treated patients ≤40 years in China.
Methods: This study included patients aged ≤40 with ATAAD who underwent surgical treatment at our institution between 2015 and 2019. The patients were categorized into groups according to heritable thoracic aortic disease (HTAD) presence or absence.

Objective: We aimed to explore the application value of unsupervised machine learning in identifying acute gastrointestinal injury (AGI) after extracorporeal circulation for acute type A aortic dissection (ATAAD).
Methods: Patients who underwent extracorporeal circulation for ATAAD at the First Hospital of Lanzhou University from January 2016 to January 2021 were included. Unsupervised machine learning algorithm was used to stratify patients into different phenogroups according to the similarity of their clinical features and laboratory test results.
