Veritas bovine pericardium for immediate breast reconstruction: a xenograft alternative to acellular dermal matrix products.

European journal of plastic surgery (2012) 

The technical advantages in utilizing human acellular dermal matrix (ADM) products as pectoral extenders in immediate breast reconstruction with tissue expanders or implants are well documented in the medical literature. In this study, the authors examine a commonly used biologic xenograft product that has not yet been described in the medical literature for use in immediate breast reconstruction to determine whether a lower overall complication rate is identified compared to published data on ADM products.

Abstract

PURPOSE: The purpose of this study was to evaluate the clinical course of bone reconstruction of the alveolar crest using homologous fresh-frozen bone harvested from deceased donors.

METHODS: A retrospective survey was based on the Castelfranco Veneto Hospital database, in which 3264 clinical records with a primary or secondary diagnosis of alveolar atrophy were collected over a 10-year period. A random sample of 483 patients with at least 5 years' follow-up was included in the survey. Patients were contacted by telephone and administered a questionnaire with specific questions to build a significant sample.

RESULTS: Of the patients, 449 (93% of the sample) had an uneventful follow-up after surgery and 93.2% received at least one implant, with a mean of 3.4 implants per patient. At the time of the survey, 93% of the patients were wearing a dental prosthesis, 86.9% had not lost any implants, and 6.7% had lost at least one implant, while 6.4% still had implants but presented some clinical problems. Finally, patients were asked to provide an index score (1-10 points) on the therapy as a whole, i.e., bone graft, implants, and prostheses. A score of insufficient (up to 5 points) was given by 5.3% of patients, of sufficient (6 to 7 points) by 6.1%, and of good/very good (over 7) by 88.6%.

CONCLUSIONS: Homologous bone for alveolar crest reconstruction can be a valid alternative to autologous grafting if specific tissue limitations are considered when planning therapy. Creeping substitution is partial and slower than in autologous grafts, especially in cases where cortical bone is thick or volume graft is very large. The quality of soft tissue coverage and mucosa lining is also important, possibly due to slower tissue revascularization, so future implants should predictably be positioned primarily within the original host bone.

Treatment for infection of artificial dura mater using free fascia lata

The Journal of craniofacial surgery (2014)

Synthetic artificial dura mater materials, such as expanded polytetrafluoroethylene sheets, are widely used in dura mater reconstruction in cases involving brain tumors or trauma surgery. In patients with postoperative infection related to the use of artificial dura mater, surgical debridement of the infected wound and removal of the artificial dura mater materials are necessary to control infection. In cases involving cerebrospinal fluid leakage, dura mater reconstruction must be performed immediately. Many useful techniques for performing dura mater reconstruction to treat postoperative infection have been reported; however, some have drawbacks with respect to the need for microvascular anastomosis or difficulties in obtaining watertight closure. We successfully treated 6 patients with postoperative artificial dura mater infection using free thigh fascia lata. Some surgeons believe that the use of free fascia in infected wounds is dangerous because free fascia is a non-vascularized tissue.

The clinical applications of human amnion in plastic surgery

Journal of Plastic, Reconstructive & Aesthetic Surgery (2014)

Amnion is widely available, economical and is easy to manipulate, process and store. Although many clinical applications are of historical interest only, amnion offers an alternative source of multi-potent or pluripotent stem cells and therefore may yet have a great deal to offer the plastic surgery and regenerative medicine community. It is the purpose of this article to review the clinical applications of human amnion relevant to plastic surgery.

The bovine pericardial patch in breast reconstruction: a case report

Il Giornale di chirurgia (2012)

In the last years there has been a growing demand of plastic surgery for soft tissue reconstruction. In response to this, many biological and synthetic devices have been produced, aiming to allow wide and complex body reshapings. Acellular dermal matrices are one of these devices, and are made of human or animal tissues made acellular after their sampling. They are used for cervical, breast and abdominal wall reconstruction.

Techniques and materials for enhancement of peripheral nerve regeneration: a literature review.

Peripheral nerve surgery performed under unfavorable conditions results in increased scar formation and suboptimal clinical outcomes. Providing the operated nerve with a protective barrier, reduces fibrosis and adhesion formation and may lead to improved outcomes. The ideal coverage material should prevent scar and adhesion formation, and maintain nerve gliding during motion. Nerve protection using autologous tissues has shown good results, but shortcomings include donor site morbidity and limited availability. Various types of methods and materials have been used to protect nerves. There are both advantages and disadvantages associated with the various materials and techniques. In this report we summarize currently used protective materials applied for nerve coverage under various surgical conditions.

Surgical treatment of infective endocarditis with aortic and tricuspid valve involvement using cryopreserved aortic and mitral valve allografts

Interactive CardioVascular and Thoracic Surgery 20 (2015)
Surgical treatment of infective and prosthetic endocarditis using allografts gives good results. Aortic allograft implantation is a common technique, while tricuspid valve replacement with a mitral allograft is very rare. Multiple valve disease in case of infective endocarditis is a surgical challenge as such patients are usually in a grave condition and results of surgical treatment are often unsatisfactory. In this article we describe a clinical case of successful surgical treatment in a patient with active infective endocarditis of aortic and tricuspid valve, complicated by an aortic-right ventricular fistula. The aortic valve and ascending aorta were replaced with a cryopreserved aortic allograft; thetricuspid valve was replaced with a cryopreserved mitral allograft.

Spinal duraplasty with two novel substitutes restored locomotor function after acute laceration spinal cord injury in rats

WILEY PERIODICALS, 2012

A dural tear is a common complication after acute laceration spinal cord injury (ALSCI). An unrepaired dural tear is associated with poor locomotor functional recovery. Spinal duraplasty with biomaterials may promote functional recovery in ALSCI. However, an ideal dural substitute has not yet been found. In this work, we investigated the possibility of using a denuded human amniotic membrane (DHAM) or DHAM seeded on bone marrow stromal cells (DHAM–BMSCs) as duraplasty biomaterials                                                         

Secondary Vaginal Atresia Treated with Vaginoplasty Using Amnion Graft: A Case Report

Journal of Clinical and Diagnostic Research. 2014 Nov, Vol-8(11): OD05-OD06

We report a case of 26-year-old primipara with last child birth 1.5 year back who presented with amenorrhoea, cyclical lower abdominal pain and dyspareunia for past six months. Examination revealed vaginal atresia secondary to previous traumatic/mismanaged vaginal delivery with haematocolpos. She was managed by vaginoplasty with amnion graft and regular dilation with soft vaginal mould for six weeks and was advised for regular intercourse after that.

Saphenous vein graft intervention: status report 2014

J Invasive Cardiol. 2014 Dec;26(12):659-67.

Given their frequent use as bypass conduits and high rates of degeneration, saphenous vein grafts (SVGs) will continue to require percutaneous coronary intervention. Due to their unique physiology, SVGs pose special challenges to the interventionalist. Preintervention evaluation of hemodynamic significance is hampered by limited data and uncertainty regarding the validity of fractional flow reserve. Intraprocedural complications, particularly distal embolization and no-reflow, are common but may be mitigated by various techniques. Despite advances in the field, SVG intervention is associated with worse outcomes - including increased rates of periprocedural myocardial infarction, restenosis, target vessel revascularization, non-target disease progression, and death - compared with native vessel intervention. This paper reviews the most recent data and techniques available to the interventionalist seeking to improve outcomes after SVG intervention.
