Objectives: to conduct a comparative assessment of the functional condition microcirculation digestive anastomosis zone in early and delayed postoperative period upon local usage autogenic growth factors (PRP). The experiment was performed on 30 mature laboratory rabbits. All animals underwent imposition two "end-to-end" intestinal anastomosis: control one at distance 15 cm from ileocecal angle...

Characteristics of blood-flow velocities were investigated at different sites in two types of coronary artery bypass grafts, sequential saphenous vein grafts (SSVG) and internal mammary artery grafts (IMAG). The latter appear to have the longest life span. The patency rate of the side-to-side anastomosis of the SSVG is better than that of the end-to-side anastomosis. The SSVG was anastomosed to...

BACKGROUND AND OBJECTIVES We sought to develop a simulation model that accurately replicates the challenges of the thoracoscopic intrathoracic anastomosis. This model is intended to serve as a teaching tool during the introduction to, and development of, the skills required to perform a thoracoscopic intrathoracic anastomosis during an Ivor Lewis minimally invasive esophagectomy. METHODS The ...

In the 20-year period ending December 31, 1973 we operated on 105 patients for palliation of tricuspid atresia (TA) with reduced pulmonary blood flow. Pott's anastomosis (85), Blalock-Taussig anastomosis (19), intrapericardial aorta (Ao)-to-right pulmonary artery (RPA) (18), Glenn procedure (3) and miscellaneous shunts (2) have been used. Of patients undergoing operation more than 15 years ago,...

BACKGROUND Successful vascular anastomosis is essential for the survival of transferred free tissue. Arterial anastomosis is typically uncomplicated because the lumen is easily maintained and the vessel walls have elasticity. Venous anastomosis, however, is more time consuming because the vessel walls are thin and extensible. This article describes, reviews, and compares 3 currently used venous...

constraints: time evolution of the adiabatic piston Christian Gruber Institut de physique th eorique Ecole Polytechnique F ed erale de Lausanne CH-1015 Lausanne, Switzerland June 22, 1998 Abstract The equations for the time evolution of the controversial adiabatic piston problem are obtained using a very primitive model of the uids. It thus shows that the 1st and 2nd laws of thermodynamics lead...

Given r > 1, we search for the convex body of minimal volume in E3 that contains a unit ball, and whose extreme points are of distance at least r from the centre of the unit ball. It is known that the extremal body is the regular octahedron and icosahedron for suitable values of r. In this paper we prove that if r is close to one then the typical faces of the extremal body are asymptotically re...
