Background Extracorporeal circulation with circuits coated surface-bound heparin has allowed reduced levels of systemic heparinization. Clinical benefits have included postoperative bleeding and less homologous blood usage. However, the effects on hemostatic fibrinolytic systems remained in part unknown. Methods Results Indications thrombin generation, platelet activation, activity were investigated patients undergoing coronary artery bypass surgery. Two groups perfused cardiopulmonary (CPB)...
Although experimental studies have indicated that blood cardioplegia may be superior to crystalloid for myocardial protection, clinical data still remain uncertain. In a previous randomised study from our institution, including 1440 patients undergoing coronary artery bypass grafting (CABG), no beneficial effects of were seen in any relevant outcome variables. The investigation was therefore extended patient population having longer pump times and ischaemic periods.Over 48-month period, all...
To evaluate the accuracy of a 3-dimensional (3D) navigation system using electromagnetically tracked tools to explore its potential in patients.The 3D was quantified on phantom and porcine model same setup vascular interventional suite. A box-shaped with 16 markers scanned 5 different positions computed tomography (CT). The registered each CT volume magnetic field. needle pointed at physical markers, spatial distances between were calculated. Contrast-enhanced images acquired from 6 swine....
OBJECTIVE Residual tumor masses are common after transsphenoidal surgery. The risk of a residual mass increases with size and parasellar or suprasellar growth. Transsphenoidal surgery is usually performed without image guidance. We aimed to investigate new technical solution developed for intraoperative ultrasound imaging during surgery, respect potential clinical use the ability identify neuroanatomy tumor. METHODS In 9 patients pituitary macroadenomas, intrasphenoidal intrasellar was...
To evaluate the in vivo feasibility of a 3-dimensional (3D) electromagnetic (EM) navigation system with electromagnetically-tracked catheters endovascular aneurysm repair (EVAR).The pilot study included 17 patients undergoing EVAR bifurcated stent-graft. Ten were assigned to control group, which standard procedure was used. The remaining 7 (intervention group) underwent an during cone-beam computed tomography image acquired after implantation main 3D presented on screen. From contralateral...
The manipulation of the surgical field in laparoscopic surgery, through small incisions with rigid instruments, reduces free sight, dexterity, and tactile feedback. To help overcome some these drawbacks, we present a prototype research development platform, CustusX, for navigation minimally invasive therapy. system can also be used planning follow‐up studies. With this platform import display range medical images, real‐time data such as ultrasound X‐ray, during surgery. Tracked tools,...
Laparoscopic surgery is performed through small incisions that limit free sight and possibility to palpate organs. Although endoscopes provide an overview of organs inside the body, information beyond surface missing. Ultrasound can real-time essential organs, which valuable for increased safety accuracy in guidance procedures. We have tested use 2D 3D ultrasound combined with CT data a prototype navigation system. In our laboratory, micro-positioning sensors were integrated into flexible...
Background Navigation systems are now frequently being used for guiding surgical procedures. Existing neuronavigation suffer from the lack of updated images when tissue changes during surgery as well userfriendly displays all essential accurate and safe guidance. Methods We have developed various new technologies improved neuronavigation. Using intraoperative 3D ultrasound (US) imaging, we registration algorithms using updating a complete multimodal multivolume map navigation. Results...
