HYPOTHESIS Complications of vascular procedures performed for tumor infiltration of major vessels or for the rescue of complex tumor resections may significantly affect perioperative patient outcome and long-term patient survival rate. DESIGN AND PATIENTS Retrospective review of 39 patients undergoing major resection for malignancy between April 1980 and April 1998; 35 patients underwent majo...

Resumen In this paper, we present a vascular tree model made with synthetic materials and which allows us to obtain images to make a 3D reconstruction. We have used PVC tubes of several diameters and lengths that will let us evaluate the accuracy of our 3D reconstruction. In order to calibrate the camera we have used a corner detector. Also we have used Optical Flow techniques to follow the poi...

The aim of this study was to determine the feasibility of the new vascular graft for aortic root reconstruction using two different surgical techniques and to evaluate the intermediate clinical and functional results. Between January 2006 and December 2007, a total of 79 patients with aortic root and valve pathologies (chronic aneurysm 70, acute aortic dissection 9) underwent valve-sparing aort...
