Anzhen Risk Evaluation System for Acute Aortic Syndrome (AZSCORE-AAS): protocol for a multicentre prospective cohort study in northern China.

Introduction: Acute aortic syndrome (AAS) is a group of acute and critical conditions, including acute aortic dissection (AAD), acute intramural haematoma and penetrating aortic ulcer. High mortality and morbidity rates result in a poor patient prognosis. Prompt diagnoses and timely interventions are paramount for saving patients' lives.

Development and validation of a nomogram for postoperative severe acute kidney injury in acute type A aortic dissection.

Background: Postoperative acute kidney injury (AKI) is a major complication associated with increased morbidity and mortality after surgery for acute type A aortic dissection (AAAD). To the best of our knowledge, risk prediction models for AKI following AAAD surgery have not been reported. The goal of the present study was to develop a prediction model to predict severe AKI after AAAD surgery.

Sufentanil: a risk factor for lactic acidosis in patients after heart valve surgery.

Backgrounds: Hyperlactatemia is a common metabolic disorder after cardiac surgery with cardiopulmonary bypass. Epinephrine use has been identified as a potential cause of increased lactate levels after cardiac surgery. Stress can lead to an increase in catecholamines, mainly epinephrine, in the body.

Massive Bleeding After Surgical Repair in Acute Type A Aortic Dissection Patients: Risk Factors, Outcomes, and the Predicting Model.

Background: Massive bleeding throughout aortic repair in acute type A aortic dissection (ATAAD) patients is a common but severe condition that can cause multiple serious clinical problems. Here, we report our findings regarding risk factors, short-term outcomes, and predicting model for massive bleeding in ATAAD patients who underwent emergent aortic repair.

Methods: A universal definition of perioperative bleeding (UDPB) class 3 and 4 were used to define massive bleeding and comprehensively evaluate patients.

Spinal Cord Protection of Aorto-Iliac Bypass in Open Repair of Extent II and III Thoracoabdominal Aortic Aneurysm.

Background: Spinal cord injury (SCI) is one of the serious complications of thoracoabdominal aortic aneurysm (TAAA) repair. Cardiopulmonary bypass (CPB) and left heart bypass (LHB) are well-established extracorporeal circulatory assistance methods to increase distal aortic perfusion and prevent spinal cord ischaemia in TAAA repair. Aorto-iliac bypass, a new surgical adjunct offering distal aortic perfusion without the need of complex perfusion skills, was developed as a substitute for CPB and LHB.

Blood Transfusion and Acute Kidney Injury After Total Aortic Arch Replacement for Acute Stanford Type A Aortic Dissection.

Aim: To evaluate the effect of packed red blood cells (pRBCs), fresh frozen plasma (FFP), and platelet concentrate (PC) transfusions on acute kidney injury (AKI) in patients with acute Stanford type A aortic dissection (ATAAD) with total arch replacement (TAR).

Method: From December 2015 to October 2017, 421 consecutive patients with ATAAD undergoing TAR were included in the study. The clinical data of the patients and the amount of pRBCs, FFP, and PC were collected.

One-stage hybrid procedure for distal aortic arch disease: mid-term experience at a single center.

Background: This study analyzes the outcomes of a one-stage hybrid procedure combining thoracic endovascular aortic repair (TEVAR) with extra-anatomic bypass in patients with distal aortic arch disease.

Methods: This retrospective study collected 103 hybrid procedures combining TEVAR with extra-anatomic bypass (mean age, 62.2±9.

Management of acute type A aortic dissection during COVID-19 outbreak: Experience from Anzhen.

Objectives: We seek to report our management protocol and early outcomes of acute type A aortic dissection (ATAAD) repair during the early phase of coronavirus disease 2019 (COVID-19).

Methods: From January 23 to April 30, 2020, we performed ATAAD repair for 33 patients, including three with pregnancy-related TAADs. Confirmation of COVID-19 depended on the results of two nucleic acid tests and pulmonary computed tomography scan.

Relationship Between Renal Function and Renal Artery Involvement in Acute Debakey Type I Aortic Dissection.

Background: The aim of this study was to analyse the differences in renal function among various types of renal artery involvement in acute Debakey Type I aortic dissection.

Methods: From January 2016 to January 2018, 304 consecutive patients with acute Debakey type I aortic dissection with renal artery involvement were included. According to computed tomography angiography (CTA) findings, renal artery involvement on one side can be classified into four types: type A, in which a large intimal tear is near the renal artery orifice; type B, the orifice of the renal artery originates entirely from the false lumen; type C, the orifice of the renal artery originates entirely from the true lumen; and type D, a renal artery dissection is observed.

Aortic dissection during pregnancy and postpartum in patients with Marfan syndrome: a 21-year clinical experience in 30 patients.

Objectives: Pregnancy-related aortic dissection (AoD) in Marfan syndrome is a lethal catastrophe. Due to its rarity and limited clinical experience, there is no consensus regarding the optimal management strategy. We seek to present our 21-year experience in such patients , focusing on management strategies and early and late outcomes.

Successful repair of acute type A aortic dissection during pregnancy at 16 gestational week with maternal and fetal survival: A case report and review of the literature.

Background: Aortic dissection during pregnancy is a rare but life-threatening event for mothers and fetuses. It often occurs in the third trimester of pregnancy and the postpartum period. Most patients have connective tissue diseases such as Marfan syndrome.

Frozen elephant trunk with modified arch reconstruction and left subclavian transposition for chronic type A dissection.

Background: Several methods of arch vessel reconstruction, such as (island) and branched graft techniques, have been proposed to treat aortic arch pathologies during total arch replacement (TAR). We seek to review our experience with modified en bloc technique and left subclavian (LSCA)-left carotid artery (LCCA) transposition in TAR and frozen elephant trunk (FET) procedure for chronic type A aortic dissection (CTAAD).

Methods: From September 2010 to September 2016, 35 consecutive patients with CTAAD underwent modified arch reconstruction with LSCA-LCCA transposition during TAR and FET procedure.

One-Stage Repair of Adult Aortic Coarctation and Concomitant Cardiac Diseases: Ascending to Abdominal Aorta Extra-Anatomical Bypass Combined with Cardiac Surgery.

Background: To evaluate one-stage repair with ascending to abdominal aorta extra-anatomical bypass combined with cardiac surgery for adult aortic coarctation (COA) concomitant with cardiac diseases.

Methods: Between February 2009 and September 2016, 24 consecutive patients (79.17% male, mean age 36.

Aorta-Iliac Bypass in Thoracoabdominal Aortic Aneurysm Repair in Young Chinese Patients.

Background: Many surgical methods of thoracoabdominal aortic aneurysm repair (TAAAR) have been introduced over the past several decades, with varying degrees of success. We developed an aorta-iliac bypass technique to treat thoracoabdominal aortic aneurysm (TAAA) in young Chinese patients. The aim of this study is to evaluate the results of this technique intraoperatively and postoperatively.

[Extra-anatomic bypass for complex aortic coarctation in adults].

Objective: To demonstrate an effective operation of extra-anatomic bypass for complex aortic coarctation in adults.

Methods: Between July 1997 and October 2010, 51 patients underwent extra-anatomic aortic bypass. There were 39 male and 12 female patients.

Validation of four different risk stratification models in patients undergoing heart valve surgery in a single center in China.

Background: Several risk stratification models have been developed for cardiac surgery. This study aimed to evaluate the accuracy of four existing risk stratification models, the Fuwai System for Cardiac Operative Risk Evaluation (FuwaiSCORE), the Society of Thoracic Surgeons 2008 cardiac surgery risk model for isolated valve surgery (the STS model), the European System for Cardiac Operative Risk Evaluation (EuroSCORE) and the initial Parsonnet's score (the Parsonnet model) in predicting prolonged intensive care unit (ICU) stay in Chinese patients undergoing heart valve surgery.

Methods: Data were collected retrospectively from records of 1333 consecutive patients who received heart valve surgery in a single center between November 2006 and December 2007.
