Although atrial fibrillation is one of the most frequent and widespread cardiac arrhythmias, there is not sufficient data on frequency and electrical cardioversion of this arrhythmia in cases of dextrocardia. The present case report describes a 66-year-old woman with atrial fibrillation and dextrocardia who was admitted to hospital with a complaint of palpitations; no cause of the atrial fibrillation was found. Electrical cardioversion was performed for termination of the arrhythmia. By placing the anterior paddle in the right parasternal area and the lateral paddle in the area where the apex of the left ventricle palpated at the right side of the chest, cardioversion was performed and sinus rhythm was achieved.  相似文献

BackgroundRobotic-assisted unicompartmental knee arthroplasty (UKA) with rigid bone fixation "can significantly improve implant placement and leg alignment. The aim of this cadaveric study was to determine whether the use of robotic systems with dynamic bone tracking would provide more accurate UKA implant positioning compared to the conventional manual technique.MethodsThree-dimensional CT-based preoperative plans were created to determine the desired position and orientation for the tibial and femoral components. For each pair of cadaver knees, UKA was performed using traditional instrumentation on the left side and using a haptic robotic system on the right side. Postoperative CT scans were obtained and 3D-to-3D iterative closest point registration was performed. Implant position and orientation were compared to the preoperative plan.ResultsSurgical RMS errors for femoral component placement were within 1.9 mm and 3.7° in all directions of the planned implant position for the robotic group, while RMS errors for the manual group were within 5.4 mm and 10.2°. Average RMS errors for tibial component placement were within 1.4 mm and 5.0° in all directions for the robotic group; while, for the manual group, RMS errors were within 5.7 mm and 19.2°.ConclusionsUKA was more precise using a semiactive robotic system with dynamic bone tracking technology compared to the manual technique.  相似文献

The incidence of extravasation of contrast medium is reported in the literature to be between 0.2?% and 0.9 %. A rare consequence of this could be compartment syndrome of the affected limb which requires immediate treatment. We report the case of a patient who developed acute compartment syndrome of the forearm after intravenous injection of radiographic contrast medium in a radiovolar vein during a computed tomography (CT) scan for multiple trauma. The clinical symptoms with pain, loss of range of motion and sensitivity functions, measurement of compartment pressure and radiological images confirmed the diagnosis. After emergency dermatofasciotomy of the forearm the full range of motion and sensitivity functions could be restored.  相似文献

Purpose  

The aim of our study was to produce a 3-D reconstruction of a CT dataset and compare it to the conventional method, with that same dataset, in terms of precision and the influence of femoral positioning.  相似文献
