FL% is associated with the severity of acute DeBakey type I aortic dissection in patients undergoing frozen elephant trunk and total arch replacement.

Objectives: The diameter, area, and volume of the true lumen and false lumen (FL) have been measured in previous studies to evaluate the extent of DeBakey type I aortic dissection. However, these indicators have limitations because of the irregular shapes of the true and false lumens and the constant oscillation of intimal flap during systole and diastole. The ratio of arch lengths seems to be a more reliable indicator.

Postoperative hypoxemia for patients undergoing Stanford type A aortic dissection.

Clinically, it is widely recognized that surgical treatment is the preferred and reliable option for Stanford type A aortic dissection. Stanford type A aortic dissection is an emergent and serious cardiovascular disease characterized with an acute onset, poor prognosis, and high mortality. However, the incidences of postoperative complications are relatively higher due to the complexity of the disease and its intricate procedure.

High preoperative bradykinin level is a risk factor for severe postoperative hypoxaemia in acute aortic dissection surgery.

New Findings: What is the central question of this study? Hypoxaemia can lead to increased postoperative mortality in patients: what are the independent risk factors for severe hypoxaemia after acute Stanford type A aortic dissection? What is the main finding and its importance? Severe postoperative hypoxaemia was found in 36.4% of patients, and it was determined that high preoperative bradykinin levels and increased BMI were independent predictors of severe postoperative hypoxaemia in patients with acute Stanford type A aortic dissection. For obese patients with high preoperative bradykinin levels, more attention should be paid to preventing severe postoperative hypoxaemia.

Low preoperative serum fibrinogen level is associated with postoperative acute kidney injury in patients with in acute aortic dissection.

Objective: Acute kidney injury (AKI) after cardiac surgery is associated with serious complication and high risk of mortality. The relationship between hemostatic system and the prognosis of patients with acute type A aortic dissection (ATAAD) has not been evaluated. The purpose of this study was to investigate the association between preoperative serum fibrinogen level and risk of postoperative AKI in patients with ATAAD.

Safety and efficacy of fibrinogen concentrate in aortic arch surgery involving moderate hypothermic circulatory arrest.

Objective: Bleeding is a common complication of cardiac surgery, especially aortic arch surgery involving moderate hypothermic circulatory arrest. Fibrinogen concentrate has been increasingly used to treat coagulopathic bleeding in cardiac surgery, although its effectiveness and safety are unknown. The aim of this prospective study was to investigate the safety and efficacy of fibrinogen concentrate in patients with acute type A aortic dissection.

Treatment of patients with aortic disease during pregnancy and after delivery.

Objective This study aimed to review treatment of patients with aortic disease during pregnancy and after delivery in Beijing Anzhen Hospital. Methods A retrospective study was conducted using data from 12 patients with aortic disease during pregnancy and after delivery in our institution from May 2005 to December 2014. Patients were provided different treatments based on the type of aortic disease and clinical characteristics.

Surgery for mitral regurgitation in patients with aortic root aneurysm: Transaortic or transseptal approach?

Objective: Mitral regurgitation is common in patients with aortic root aneurysm. Mitral valve repair (MVP) or replacement (MVR) can be performed for these patients through either a transverse aortotomy (TA) or transseptal approach (TS). This study sought to compare the early outcomes of mitral valve surgery through the TA and TS approaches and decide which is optimal for this subset of patients.

Changes in the Hemostatic System of Patients With Acute Aortic Dissection Undergoing Aortic Arch Surgery.

Background: Aortic arch surgery for patients with acute aortic dissection is frequently complicated by excessive bleeding and transfusion of allogeneic blood products. However, the physiopathology of acute aortic dissection and surgery-induced coagulopathy has never been precisely studied. The aim of the present study is to describe the changes of the perioperative hemostatic system in patients with acute aortic dissection undergoing aortic arch surgery.

[Nanometer detection of self-assembly morphology of sodium hyaluronate injection on mica].

Objective: To detect the self-assembly morphology of sodium hyaluronate injection on mica using atomic force microscopy(AFM).

Methods: Atomic force microscopy with nanometer resolution was used to observe the self-assembly morphology of different concentrations of sodium hyaluronate injection on mica at room temperature.

Results: The self-assembly morphology of 0.

Evaluation of transcutaneous electroacupoint stimulation with the train-of-four mode for preventing nausea and vomiting after laparoscopic cholecystectomy.

Objective: To evaluate the efficacy of transcutaneous electroacupoint stimulation with a train-of-four (TOF) mode for the prevention of postoperative nausea and vomiting (PONV) in the patients undergoing laparoscopic cholecystectomy.

Methods: Ninety-six ASA Grade I - II patients scheduled for laparoscopic cholecystectomy were randomized into Neiguan (P6) electroacupoint stimulation group (treated group) and a placebo control group (placement of electrodes without electroacupoint stimulation). The anesthetic regimen was standardized by needling at Neiguan on the left side and connecting the TOF peripheral nerve stimulator.

[Effect of electroacupuncture on bispectral index of electroencephalography in patients undergoing subtotal thyroidectomy].

Objective: To investigate the effects of electroacupuncture on bispectral index (BIS) of electroencephalography in patients undergoing subtotal thyroidectomy.

Methods: Sixty patients were equally randomized into group A given electroacupuncture combined with cervical plexus block (CPB) and group B given CPB alone. After needling sensation was reached in bilateral "Hegu" and "Neiguan" acupoints, 5 min of high frequency electrical stimulation by electrical stimulation device followed with CPB was applied to group A, while only CPB was performed in group B.

Femoral artery cannulation in Stanford type A aortic dissection operations.

The aim of this study was to evaluate femoral artery cannulation in Stanford type A aortic dissection operations. Between March 1994 and December 2001, 88 patients with Stanford type A aortic dissection underwent surgery with cardiopulmonary bypass and perfusion through the femoral artery; 31 of them had deep-hypothermic circulatory arrest. False lumen perfusion was detected in 8 patients (9.
