The investigations on the pressure wave propagation along the arterial network and its relationships with vascular physiopathologies can be supported nowadays by numerical simulations. One dimensional (1D) mathematical models, based on systems of two partial differential equations for each arterial segment suitably matched at bifurcations, can be simulated(More)
Metastatic involvement of the gallbladder in melanoma is rare, but constitutes the most common metastatic lesion involving this organ. The surgical management seems to be indicated for patients with isolated and resectable gallbladder metastases to avoid symptoms or tumor complications. We report on a case of a young woman with an isolated metastatic(More)
BACKGROUND The aim of this study was to determine the feasibility and efficacy of repairing large abdominal incisional hernias by reconstructing the midline using bilateral abdominis rectus muscle sheath (ARS) relaxing incisions and a biological material onlay. METHODS Between January 2002 and December 2008, 71 patients underwent repair of large(More)
BACKGROUND Traditional laparoscopic cholecystectomy (LC) includes the use of 4 trocars. The aim of this study is to show that LC can be performed safely with the 3-trocar technique, thus simplifying a very well-known technique. METHODS We performed a retrospective analysis of 1878 patients (male-to-female ratio was 1:3; median age of 44 y) that underwent(More)
This work addresses the problem of prescribing proper boundary conditions at the artificial boundaries that separate the vascular district from the remaining part of the circulatory system. A multiscale (MS) approach is used where the Navier-Stokes equations for the district of interest are coupled to a non-linear system of ordinary differential equations(More)
The authors present a case of an adenoma of the nipple in a 61-year-old man who reported a 6-month history of nodularity and itching at his left nipple. Examination revealed a firm, well-defined, vascularized tumor measuring .8 cm that altered the normal anatomy of the nipple. A total excision of the nipple and areola was performed. The histological(More)
INTRODUCTION Metastatic neoplasms to the thyroid gland are rare in clinical practice. Clear cell renal carcinoma is the most frequent site of origin of thyroid metastases and represents 12 to 34% of all secondary thyroid tumors. Tumor-to-tumor metastases, in which a thyroid neoplasm is the recipient of a metastasis, are exceedingly rare. We report a case of(More)
The aim of the virtual vascular project (ViVa) is to develop tools for the modern hemodynamicist and cardiovascular surgeon to study and interpret the constantly increasing amount of information being produced by noninvasive imaging equipment. In particular, we are developing a system able to process and visualize three dimensional (3D) medical data,(More)
We present an experimental catheter insertion simulation system that provides users co-registered haptic and head-tracked stereoscopic visual feedback. The system works on patient-specific volumetric data acquired using standard medical imaging modalities. The actual needle insertion operation is simulated for individual patients, rather than being an(More)
The aim of this study was to evaluate the potential advantages of the use of Harmonic Scalpel in thyroidectomies in terms of operative time and complications. Between May 2007 and June 2010 1151 patients were submitted to total thyroidectomy. In 681 thyroidectomies were performed using harmonic scalpel FOCUS (group A), in 470 without it (group B). Mean(More)
