Perforator flaps are perfused through a long vessel whose calibre decreases from its origin to the skin, because all branches have been sealed, resulting in a conduit with resistances in series, rather than a tree with resistances in parallel, as in the normal systemic circulation. This study was planned to assess whether the differences between perforator(More)
The vascular architecture within a perforator flap is different from a conventional muscle or myocutaneous flap. The purpose of this paper is to understand the correlation between flow rate and flap size in perforator flaps. With extrapolation of these data, we have provided an indirect analysis of the venous drainage and its correlation with flap size. A(More)

A finite volume andWENOmodel is developed, validated and applied to a one-dimensional numerical investigation of the vascular system. Suitable balance laws are spatially integrated using a finite volume WENO approach. Time integration is performed using a five steps, fourth order accurate Runge–Kutta strong stability preserving scheme. A detailed(More)
BACKGROUND Absorbable sutures are not generally accepted by most vascular surgeons for the fear of breakage of the suture line and the risk of aneurysmal formation, except in cases of paediatric surgery or in case of infections. Aim of this study is to provide evidence of safety and efficacy of the use of absorbable suture materials in carotid surgery. (More)
PURPOSE This study used cone-beam computed tomography to evaluate morphologic changes of the mandibular anterior ridge after using augmented corticotomy plus accelerated orthodontia to decompensate mandibular incisors in patients with surgical skeletal Class III. MATERIALS AND METHODS Fourteen patients (8 men, 6 women; mean age, 26.14 yr) with skeletal(More)
This paper aims at showing how the so-called mathematical kinetic theory for active particles can be properly developed to propose a new system biology approach. The investigation begins with an analysis of complexity in biological systems, continues with reviewing a general methodology to reduce complexity and furnishes the mathematical tools to describe(More)
