Abstract Objective. The purpose was to explore the characteristics and nursing points of surgical and interventional treatment for elderly cerebral aneurysm. Methods. 100 elderly patients with cerebral aneurysm treated in our hospital from January 2017 to December 2019 were selected, and divided into craniotomy group (40 patients with neurosurgical clipping) and interventional surgery group (60 patients with endovascular interventional embolization) according to the treatment method to compare the operation time, hospitalization time, hospitalization expenses, degree of brain injury, complications and prognostic scores of the patients in two groups. Meanwhile, the relationship between the factors (age, aneurysm… More >

Abstract Background: Pseudoaneurysm complicating right ventricular outflow tract (RVOT) with conduit placement was an infrequent complication but with potential for significant morbidity and mortality, and a more unusual pseudoaneurysm after RVOT patching was investigated here. Methods: Patients diagnosed as pseudoaneurysms at our institution from 2010 to 2019 were reviewed and their clinical characteristics were analyzed. Results: A total of seven patients developed pseudoaneurysm in RVOT were identified. One pseudoaneurysm arose after placement of a conduit between the right ventricle and the pulmonary artery, and the other six formed after RVOT patching. One patient presented with arrhythmia, one patient… More >

Abstract Background: This retrospective cohort study aimed to explore the causes of death in children with congenital heart disease (CHD) after cardiac surgery in one of the biggest cardiac centers for children with CHD in China. Methods: A total of 26,856 children undergoing cardiac surgery from January 1, 2012 to December 31, 2019 were included. Based on the clinical data, the causes of death were divided into ten categories and further compared among different periods, types of CHD and surgical procedures. Results: Of all patients, 513 (1.9%) died (median age 162 d, median weight 5.6 kg). The mortality… More >

Abstract Objective: Serum ferritin has been identified as a prognostic marker in patients with a variety of diseases. In the present study we aim to determine the prevalence of risk factors and outcomes for hyperferritinemia in children undergoing cardiac surgery with cardiopulmonary bypass for congenital heart defects. Methods: The serum ferritin levels of 457 children between the ages of twentyeight days and three years undergoing cardiopulmonary bypass surgery between June 1, 2017 and June 1, 2018 were analyzed. The prevalence of early postoperative hyperferritinemia was investigated; hyperferritinemia was defined as a ferritin level ≥250 ng/ml. Multivariable regression… More >

Abstract Objective: To test the hypothesis that circulating miRNAs-146a, -146b, -155, and -21 reflect the inflammatory state of children following heart surgery, and that they may, therefore, correlate with postoperative parameters. We aimed to quantify miRNAs in blood samples from pediatric patients before and 6, 12, and 24 hours after surgery and to evaluate correlations between the miRNA levels and the postoperative course. Setting: PICU. Patients: Forty-two pediatric patients with CHD who underwent cardiac surgery at Safra Children’s Hospital between 2012–2016. Interventions: none. Outcome Measures: The primary outcomes were the postoperative cardiac complications and the secondary outcomes were the More >

Abstract In order to solve the problem of high computing cost and low simulation accuracy caused by discontinuity of incision in traditional meshless model, this paper proposes a soft tissue deformation model based on the Marquardt algorithm and enrichment function. The model is based on the element-free Galerkin method, in which Kelvin viscoelastic model and adjustment function are integrated. Marquardt algorithm is applied to fit the relation between force and displacement caused by surface deformation, and the enrichment function is applied to deal with the discontinuity in the meshless method. To verify the validity of the More >

Abstract The expression changes of miR-625-3p and miR-449a in osteosarcoma patients after surgery is the critical study in this paper. Analysis of their prognosis and risk factors can be helpful in understanding the prognostic value for clinical purposes. Fifty-eight patients with osteosarcoma diagnosed in our hospital were considered as the research group (RG), and 52 health subjects at the same time were collected as the control group (CG). Fluorescence quantitative PCR (RTPCR) was employed to test the expression levels of miR-625-3p and miR-449a in the serum of subjects in both groups before surgery and patients in… More >

Abstract Background: In an effort to reduce postoperative trauma and achieve more cosmetic results, minimally invasive approaches to correct congenital heart anomalies have been recently proposed and increasingly adopted. Here we describe our experience for the past 23 years. Methods: Patients who underwent a surgical procedure between February 1996 and March 2019 with a minimally invasive approach for the correction of congenital heart disease in our center were included in this study. A statistical analysis was carried out to compare the results of the different minimally invasive techniques. A meta-analysis was conducted to compare our results in… More >

Abstract Adults with congenital heart disease (ACHD) constitute a growing population with complex cardiac physiopathology and frequent extra-cardiac involvement. The recent dramatic improvement of their life expectancy has resulted in an increasing proportion of ACHD patients requiring non-cardiac surgery. While a large body of evidence demonstrated the importance of an accurate risk assessment in patients with acquired heart disease before noncardiac surgery in order to reduce perioperative morbidity and mortality and detailed algorithms have been released by international societies, no specific guidelines are available for the perioperative management in this population. Nonetheless, understanding the complex anatomy… More >

Abstract Computational fluid dynamics (CFD) has been widely used for studying intracranial aneurysm hemodynamics, while its use for guiding clinical strategy is still in development. In this study, CFD simulations helped inform treatment decision for a middle cerebral artery (MCA) aneurysm case was investigated. A patient with a 10.4 × 9.8 mm aneurysm attached with a small aneurysm at the edge of the trifurcation in the left MCA was included in this study. For removing the MCA aneurysm, two scenarios were considered: Plan-A involved clipping the small aneurysm and Plan-B involved clipping the whole aneurysm. A… More >
