Background Basic science research in cardiopulmonary resuscitation (CPR) is limited by challenges in obtaining haemodynamic data from models that simulate physiological processes. In this study, we assessed the morphology of the heart and lungs and calculated the ejection fractions of cardiac chambers during CPR using a virtual simulation. Methods...

Analyses of registries and medical imaging suggest that laparoscopic surgery may be penalized with a high incidence of trocar-site hernias (TSH). In addition to trocar diameter, the location of the surgical wound (SW) may affect TSH incidence. The intra-abdominal pressure (IAP) exerted on the abdominal wall (AW) might also influence the appearance...

The effect of the dimensions of the thoracic cage on the resuscitation outcome of cardiopulmonary resuscitation (CPR) maneuvers has long been debated. In this study, the effect of changes in the rib cage dimensions on the achieved compression depth was investigated using finite element simulations. A total of 216 different rib cage geometry models...

Cardiopulmonary resuscitation (CPR) is an emergency procedure performed on patients during cardiac and respiratory arrest. This procedure externally activates the cardiac and respiratory systems via the delivery of chest compression and artificial ventilation. As the main purpose of CPR is to recirculate the blood flow, prediction of the myocardium...

Background An accurate knowledge of the relocation of prostate neoplasms during biopsy is of great importance to reduce the number of false negative results. Prostate neoplasms are visible in magnetic resonance images (MRI) but it is difficult for the practitioner to locate them at the time of performing a transrectal ultrasound (TRUS) guided biops...

An ostomy is a surgical procedure by which an artificial opening in the abdominal wall, known as a stoma, is created. We assess the effects of stoma location on the abdominal wall mechanics. We perform three-dimensional finite element simulations on an anatomy model which was generated on the basis of medical images. Our simulation methodology is e...

The biomechanical response of a human rib cage to cardiopulmonary resuscitation maneuvers was investigated by means of finite element simulations. We analyzed the effect of the location where the force was applied on the achieved compression depths and stress levels experienced by the breastbone and ribs. For compression locations on the breastbone...

An ostomy is a surgical procedure by which an artificial opening in the abdominal wall, known as a stoma, is created. We assessthe effects of stoma location on the abdominal wall mechanics. We perform three–dimensional finite element simulations on ananatomy model which was generated on the basis of medical images. Our simulation methodology is ent...

Background: An accurate knowledge of prostate lesions relocation during biopsy is of great importance to prevent mispositioning of the needle and thus reduce the chance of faulty biopsy results (false negatives). Prostate lesions are visible in magnetic resonance images (MRI) but it is difficult for the practitioner to locate them at the time of pe...

Dry-stone elements represent an important aspect of rural identity, and by nature, their constructive and volumetric elements have been eclipsed by their characteristics. Current massive data capture techniques, including photogrammetry, can offer new analysis procedures that will improve existing management and cataloguing methods. Such methods mu...

The alteration of blood flow around an OPTEASE® inferior vena cava filter with one or two blood clots attached was investigated by means of computational fluid dynamics. We used a patient–specific vein wall geometry, and we generated different clot models with shapes adapted to the filter and vein wall geometries. A total of eight geometries, with...

https://authors.elsevier.com/a/1ZQ~FcV4L381G Background and objective: Abdominal hernia repair is one of the most often performed surgical proce- dures worldwide. Numerical simulations of the abdominal wall mechanics can be a valuable tool to devise actions aimed at preventing hernia formation. A first step towards this goal is the development of...

Computational fluid dynamics was used to simulate the flow of blood within an inferior vena cava (IVC) geometry model that was reconstructed from computed tomography images obtained from a real patient. The main novelty of the present work is that we simulated the implantation of four different filter models in this realistic IVC geometry. We consi...

Deep venous thrombosis (DVT) is a common disease. Large thrombi in venous vessels cause bad blood circulation and pain; and when a blood clot detaches from a vein wall, it causes an embolism whose consequences range from mild to fatal. Walking is recommended to DVT patients as a therapeutical complement. In this study the mechanical effects of walk...
