Evolving Risk Factors for Mortality after Lung Transplantation over the Last 10 Years: Insights from a Single-Centre Database

2016

s S233 218 (82%) patients received pooled platelet transfusion -median (IQR) 1(1-2) U. 209 (79%) and 129 (49%) patients received fresh frozen plasma (FFP) and cryoprecipitate with a median (IQR) of 3(2-4) and 0(0-0) U respectively. Conclusion: Rate and volume of transfusion of blood products compare favourably with centres performing surgery off CPB or on ECMO. Requirement for ECMO particularly for BTT, but also PGD is associated with high transfusion requirements.

Endovascular treatment of acute bleeding complications in traumatic aortic rupture and aortobronchial fistula.

2001

Objective: Herein we report our experience in placement of endovascular stentgrafts in the descending aorta in patients with acute bleeding complications due to traumatic rupture or aortobronchial fistula. Methods: Six patients (one woman, five men, mean age 47 ^ 19 years) were treated from September 1995 to February 2000 by implantation of endovascular stentgrafts in the descending aorta. Indications included traumatic ruptures of the aortic isthmus (na 3) and aortobronchial fistulas (na 3). All procedures were performed under general anaesthesia. The implants were introduced under fluoroscopic guidance via the aorta (na 1), the iliac (na 4) or femoral (na 2) artery, respectively. Results:…

Social robots and therapeutic adherence: a new challenge in pediatric asthma?

2020

Social Robots are used in different contexts and, in healthcare, they are better known as Socially Assistive Robots. In the context of asthma, the use of Socially Assistive Robots has the potential to increase motivation and engagement to treatment. Other positive roles proposed for Socially Assistive Robots are to provide education, training regarding treatments, and feedback to patients. This review evaluates emerging interventions for improving treatment adherence in pediatric asthma, focusing on the possible future role of social robots in the clinical practice.

Prediction of mortality rate in acute type A dissection: the German Registry for Acute Type A Aortic Dissection score.

2020

Abstract OBJECTIVES The goal was to develop a scoring system to predict the 30-day mortality rate for patients undergoing surgery for acute type A aortic dissection on the basis of the German Registry for Acute Type A Aortic Dissection (GERAADA) data set and to provide a Web-based application for standard use. METHODS A total of 2537 patients enrolled in GERAADA who underwent surgery between 2006 and 2015 were analysed. Variable selection was performed using the R-package FAMoS. The robustness of the results was confirmed via the bootstrap procedure. The coefficients of the final model were used to calculate the risk score in a Web-based application. RESULTS Age [odds ratio (OR) 1.018, 95% …

Neutrophil Adherence to Activated Saphenous Vein and Mammary Endothelium After Graft Preparation

2005

Interaction of circulating leukocytes and vascular endothelium plays an important role in vasoconstriction, endothelial dysfunction, and vascular injury. Dilation procedures of grafts before coronary artery bypass graft surgery might lead to vascular injury and subsequent bypass graft disease.We analyzed in vitro the adherence of fluorescence-labeled polymorphonuclear neutrophils (PMNs) to endothelium of human saphenous vein grafts or internal mammary artery grafts after stimulation with thrombin (0.5 to 2 U/mL) or dilating procedures. Furthermore, we investigated endothelial function of prepared grafts.Thrombin stimulation resulted in a dose-dependent increase of PMN adherence to the endot…

Risk and Complication Management in Esophageal Cancer Surgery: A Review of the Literature

2015

Esophagectomy for cancer is a highly complex and demanding two-cavity procedure associated with a considerable morbidity and mortality. There are several controversies with regard to the optimal risk and complication management. Strategies include patient selection, optimization of malnutrition, hospital and surgeon volume, intraoperative anesthesiological and surgical measures, and postoperative management of complications. In this article, we review the literature on these aspects that have an impact on outcomes after esophagectomy.

Contemporary spinal cord protection during thoracic and thoracoabdominal aortic surgery and endovascular aortic repair: a position paper of the vascu…

2015

Ischaemic spinal cord injury (SCI) remains the Achilles heel of open and endovascular descending thoracic and thoracoabdominal repair. Neurological outcomes have improved coincidentially with the introduction of neuroprotective measures. However, SCI (paraplegia and paraparesis) remains the most devastating complication. The aim of this position paper is to provide physicians with broad information regarding spinal cord blood supply, to share strategies for shortening intraprocedural spinal cord ischaemia and to increase spinal cord tolerance to transitory ischaemia through detection of ischaemia and augmentation of spinal cord blood perfusion. This study is meant to support physicians cari…

Long-term results after thromboendarterectomy for chronic pulmonary embolism1

1999

Objective: In patients with chronic thromboembolic pulmonary hypertension, pulmonary vascular resistance (PVR) can be reduced by pulmonary thromboendarterectomy (PTE). In this study, long-term symptomatic and hemodynamic effects were investigated. Methods: Twenty-two patients (12 female, 10 male, mean age 40 years, preoperative NYHA functional class II/III/IV: n = 1/12/9) were re-evaluated 48‐72 months (mean 60 months) after surgery. In addition to clinical assessment, radiologic, hemodynamic and echocardiographic investigations were performed. Results: All patients reported a marked improvement of their clinical condition. At follow-up, 11 patients were identified as NYHA class I, 10 as NY…

German Registry for Acute Aortic Dissection Type A (GERAADA)--new software design, parameters and their definitions.

2011

BACKGROUND The working group for aortic surgery and interventional vascular surgery of the German Society for Thoracic and Cardiovascular Surgery (GSTCVS) initiated the web-based German Registry for Acute Aortic Dissection type A (GERAADA). It is the project's aim to collect standardized data from a large pool of patients with acute aortic dissections type A (AADA) to gain a deeper insight and knowledge to improve surgical therapies and perioperative management for these patients in the future. METHODS In addition to new medical insights, the working group has gained more experience over the last 4 years in how to collect valid and high-quality data. This experience led us to revise the dat…
