Background: Abdominal procedures in patients with coronary artery disease or severe valvular disease have high risk of mortality and morbidity. Aims: In order to prevent bile peritonitis after ...cardiac surgery, to reduce the hospitalization course, and to decrease the mortality and morbidity after the surgery, laparascopic cholecystectomy and open‐heart surgery were performed at the same time. Methods: Laparascopic cholecystectomy and open‐heart surgery were performed on two patients who had been referred to Cardiothoracic Ward of Modarres Hospital, Tehran, Iran. Results: Simultaneous classic laparascopic cholesystectomy was successfully performed on two different open‐heart patients, one with coronary artery disease for coronary artery bypass surgery and the other with severe mitral valve disorder for mitral valve replacement. Conclusions: Abdominal procedures are suggested to be done with cardiac surgery at the same time with laparascopic technique to reduce mortality and morbidity in these patients.
In this paper, we propose a scheme for Edge Detection in Digital Image based on the Residue Numbers System which leads to performance of the integration circuits with high speeds and high security ...and low power for Digital Image Processing. In this method, Edge Detection in Digital Images performs based on convolution operation between pixel values and applicable mask and also saving of obtained values of edges in the LUT memories and threshold operations by using values in Look-Up table. All operations in this method perform in Residue Numbers System. Then we design circuits for edge detection and of decimal to residue conversion and vice versa which in is used Matlab software and also VLSl tools for simulation. Preliminary simulation results show that the proposed scheme has the ability of edge detection of digital images.
