Video-assisted two-stage basilic vein transposition for creation of brachio-basilic arteriovenous fistulae
2012
We report our experience in a mixed minimally-in- vasive technique for the two-stage transposition of basilic vein on a small series of eight patients. The operative tech- nique consisted of a modified endoscopic (1) approach for the two-stage transposition (2). The intervention was performed under Brachial Plexus Block (3).
The use of a new kind of low profile retractor for arteriovenous fistula procedure simplifies and speeds up the intervention
2009
Purpose The aim of this study was to demonstrate the effectiveness of a new kind of disposable surgical retractor in arteriovenous fistula (AVF) procedures in order to achieve an easier, faster and safer surgical intervention. Methods Between January and June 2008, 22 AVF procedures were performed using the 3PAWS ReeTrakttrade; (Insightra Inc. - Irvine, Ca., USA) a self-retaining, low profile retractor. An equivalent patient sample, in which an AVF was performed using conventional retraction devices, was considered for comparison of the intra- and post-operative results. Results In all of the 22 AVF procedures performed, the ReeTrakt™ system has simplified the performance of the surgical te…
Juvenile central ossifying fibroma of the mandible: a case report
2010
Central ossifying fibroma is a rare fibro-osseous neoplasm in young children. It is highly aggressive and has a strong tendency to recur. We describe an 11-year-old girl with juvenile central ossifying fibromas of the mandible that caused obstruction of tooth eruption of the lower left second premolar. Oral examination revealed the presence of the primary lower left second molar and a small bony hard swelling over the left side of the mandibular body. After a computed tomographic scan, an incisional biopsy was performed, and the lesion proved to be a juvenile ossifying fibroma. Although this tumor often recurs early, and many authors suggest radical en bloc resection, we performed a more co…
Never say never again: A bone graft infection due to a hornet sting, thirty-nine years after cranioplasty
2017
Background: Cranioplasty (CP) is a widespread surgical procedure aimed to restore skull integrity and physiological cerebral hemodynamics, to improve neurological functions and to protect the underlying brain after a life-saving decompressive craniectomy (DC). Nevertheless, CP is still burdened by surgical complications, among which early or late graft infections are the most common outcome-threatening ones. Case Description: We report the case of 48-year-old man admitted to our neurosurgical unit because of a painful right frontal swelling and 1-week purulent discharge from a cutaneous fistula. He had been undergone frontal CP because of severe traumatic brain injury (TBI) when he was 9-ye…
Vacuum inversion and securing of distal colonic pseudodiverticula with novel spiked O-rings
2015
Background Diverticular disease is increasingly prevalent in Western societies and is associated with significant morbidity. Objective Two-stage endoscopic device development for inversion and secured ligation of colonic diverticula; first, human cadaver studies were performed to measure forces required for diverticular inversion; second, a novel set of devices (elastic spiked O-ring with delivery system) was tested in animals. Design Prospective, observational study of human cadavers and prospective, interventional study of a porcine model. Setting University hospital pathology laboratory and animal facility. Intervention Full-thickness inversion of the colonic wall with a pipelike deliver…
Histological findings of the internal inguinal ring in patients having indirect inguinal hernia
2009
BACKGROUND: Aiming to deepen the understanding of the factors involved in the genesis of groin hernia, this study is focused on identifying the histological changes within the muscle fibers of the internal inguinal ring in patients having indirect inguinal hernia. METHODS: In eight patients with primary or recurrent bilateral indirect inguinal hernia who underwent a Stoppa open posterior inguinal hernia repair, a tissue specimen from the edge of the internal inguinal ring was biopsied and histologically examined. RESULTS: In all of the tissue samples, remarkable degenerative changes such as fibrohyaline degeneration of the muscle fibers, vascular congestion, and phlogistic infiltration thro…
The "Tokyo" consensus on propeller flaps
2011
Background: Overthepastfewyears,theuseofpropellerflaps,whichbasetheir blood supply on subcutaneous tissue or isolated perforators, has become in- creasingly popular. Because no consensus has yet been reached on terminology and nomenclature of the propeller flap, different and confusing uses of the term can be found in the literature. Methods: Inthisarticle,theauthorsreporttheconsensusonthedefinitionand classification of propeller flaps reached by the authors that gathered at the First Tokyo Meeting on Perforator and Propeller Flaps in June of 2009. Some peculiar aspects of the surgical technique are discussed. Results: A propeller flap can be defined as an “island flap that reaches the reci…
Free Flaps for Anterior Chest Wall Reconstruction
2020
Reconstruction of full-thickness chest wall defects usually entails the use of regional pedicled myocutaneous flaps as first-choice option. As defect complexity increases and local options are not available, microsurgical reconstruction is required to transfer reliable and well-vascularized tissues from distant sites. Size, anatomic location, presence of dead spaces, and extent of eventual bone defect should be assessed for proper selection of the flap. Regional recipient vessels should be previously identified and checked in order to consider alternatively the need of extension of distant recipient vessels through arteriovenous (AV) loops or vein graft interposition.

FLiGS Score: A New Method of Outcome Assessment for Lip Carcinoma–Treated Patients
2015
Lip cancer represents 25% of all oral cavity carcinomas; it peaks in the sixth and seventh decades, with males predominating by 3 to 1. The lower lip is approximately 12 times more likely to be affected, owing to its greater exposure to the sunlight. Surgical oncologic and reconstructive treatment of lip cancer has advanced dramatically, but lip distortion or loss resulting from neoplasms or from their surgical treatment has considerable functional and cosmetic effects with resultant nutritional, physical, and psychological detriments.1–8 Traditional indicators, such as survival rate and disease-free interval, are no longer adequate for answering questions on outcome not considering the phy…
