Background: Aortic dissection is the most common acute aortic syndrome, and renal artery is the most common involved artery. The size and location of the re-entry tear directly affect the blood flow enhancement of the false lumen branch artery after surgery. In this study, the morphology and hemodynamics of the re-entry tear were comprehensively analyzed, and the location and size of the re-entry tear were quantitatively evaluated to calculate the re-entry tear index (RTI).

View Article and Find Full Text PDFBackground: Acute renal failure (ARF) is the most common major complication following cardiac surgery for acute aortic syndrome (AAS) and worsens the postoperative prognosis. Our aim was to establish a machine learning prediction model for ARF occurrence in AAS patients.
Methods: We included AAS patient data from nine medical centers ( = 1,637) and analyzed the incidence of ARF and the risk factors for postoperative ARF.
Background: The renal artery is often involved in aortic dissection, leading to kidney ischaemia and renal dysfunction. However, some patients with aortic dissection with combined renal artery involvement do not show clinical renal dysfunction. This study aimed to analyse the relationship between renal artery involvement and renal function.

Case Presentation: We presented a case of a pregnant (20 weeks gestation) patient with CoA associated with ruptured aortic pseudoaneurysm who was successfully rescued using a novel hybrid strategy.
Background: Aortic anastomotic leak (AAL) is knotty complication after aortic replacement. We aimed to evaluate the feasibility and efficacy of the techniques of trans-catheter AAL closure as well as to evaluate the impact of the new classification on the interventional closure.
Methods: From October 2015 to November 2017, 20 consecutive high surgical risk patients (mean age 47±12 years, 13 males) were referred to our center for trans-catheter closure AALs.
Background: To determine the prevalence, clinical and imaging features of intimal tear detected by ECG-gated multidetector computed tomography (MDCT) and confirmed by surgery in patients with acute type A intramural hematoma (ATAIMH) and acute type A aortic dissection (AAAD).
Methods: This retrospective study involved analysis of the intimal tear characteristics in 72 consecutive patients with ATAIMH and 209 with AAAD who were diagnosed by MDCT. The size and location of the intimal tear were measured and compared between these two groups of patients.
Background: Acute aortic dissection (AAD) is the most devastating aortic pathology, and the incidence is increasing worldwide. However, the occurrence and development of AAD are unpredictable. A thorough understanding of the serum metabolic landscape through metabolomic analysis may help identify new biomarkers for AAD and offers new insights into its prevention and evaluation.

Methods: From January 2014 to December 2018, a total of 89 patients with traumatic blunt aortic injuries were treated with emergency TEVAR in our center. Their clinical data such as demographics, operative details and postprocedure outcomes were analyzed retrospectively in this study using SPSS 20 software.
Background: The preferred treatment for uncomplicated type B dissection (thoracic endovascular aortic repair [TEVAR] or medical) is still under debate. Since 2001, our center has performed TEVAR for uncomplicated type B dissection. Based on our data, 5- and 10-year survival rates among patients with uncomplicated type B dissection after TEVAR were 96.

Methods: A total of 751 patients with uncomplicated type B dissection who underwent TEVAR at our centre between May 2001 and December 2013 were retrospectively reviewed. The mean age of all patients (619 males and 132 females) was 52.
Aortic dissection is an acute large vessel disease characterized by sudden onset, rapid disease progression and high mortality. Color doppler ultrasound analyzed the morphological and hemodynamic status of aortic branches before and after aortic dissection surgery, including carotid, subclavian, renal, celiac, superior mesenteric and iliac arteries. Transthoracic echocardiography, vascular ultrasound, transesophageal echocardiography, intravascular ultrasound and contrast-enhanced ultrasonography are complementary to aortic multi-slice spiral computed tomography angiography for diagnosis, treatment and prognostic evaluation.

Methods: A water tank was filled with 5 L of experimental liquid after the circular flow pressure test platform with a glass aneurysm model, and a multilayer stent was built. Pressure at the middle part and the distal aneurysm neck part of the model was then measured.
Objective: To determine the maximum dose of continuously infused mivacurium for intraoperative neuromonitoring and observe its adverse effects in thyroid surgery.
Methods: Twenty-eight patients undergoing thyroid surgery with intraoperative neuromonitoring received continuous infusion of mivacurium at the initial rate of 5.43 μg?kg?min, and the infusion rate for the next patient was adjusted based on the response of the previous patient according to the results of neurological monitoring.

Objective: To investigate the effect of propofol and operative trauma on the neurodevelopment and cognitive function of the developing brain and its mechanism.
Methods: A total of 104 postnatal day 13 Sprague-Dawley rats were randomly divided into 4 groups: control group (treated by 7.5 mL/kg saline and sham surgery), propofol group (treated by 75 mg/kg propofol), surgery group (with abdominal surgery under local anesthesia) and propofol+surgery group (with abdominal surgery under local anesthesia plus 75 mg/kg propofol anesthesia).
Background: Misdiagnosis of acute aortic dissection (AAD) can lead to significant morbidity and death. Soluble ST2 (sST2) is a cardiovascular injury-related biomarker. The extent to which sST2 is elevated in AAD and whether sST2 can discriminate AAD from other causes of sudden-onset severe chest pain are unknown.
