Treatment for infection of artificial dura mater using free fascia lata

Nakano T, Yoshikawa K, Kunieda T, Arakawa Y, Kikuchi T, Yamawaki S, Naitoh M, Kawai K, Suzuki S. 05 July 2014

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

N.G. Fairbairn, M.A. Randolph, R.W. Redmond 20 May 2015

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 amnion muscle combined graft (AMCG) conduits: a new alternative in the repair of wide substance loss of peripheral nerves

Riccio M, Pangrazi PP, Parodi PC, Vaienti L, Marchesini A, Neuendorf AD, Bottegoni C, Tos P, Geuna S. 31 August 2014

Abstract

The use of autologous sural nerve grafts is still the current gold standard for the repair of peripheral nerve injuries with wide substance losses, but with a poor rate of functional recovery after repair of mixed and motor nerves, a limited donor nerve supply, and morbidity of donor site. At present, tubulization through the muscle vein combined graft, is a viable alternative to the nerve autografts and certainly is a matter of tissue engineering still open to continuous development, although this technique is currently limited to a critical gap of 3 cm with less favorable results for motor function recovery. In this report, we present a completely new tubulization method, the amnion muscle combined graft (AMCG) technique, that consists in the combination of the human amniotic membrane hollow conduit with autologous skeletal muscle fragments for repairing the substance loss of peripheral nerves and recover both sensory and motor functions. In a series of five patients with loss of substance of the median nerve ranging 3-5 cm at the wrist, excellent results graded as S4 in two cases, S3+ in two cases, and S3 in one case; M4 in four cases and M3 in one case were achieved. No iatrogenic damage due to withdrawal of a healthy nerve from donor site was observed. This technique allows to repair extensive loss of substance up to 5 cm with a good sensory and motor recovery. The AMCG thus may be considered a reasonable alternative to traditional nerve autograft in selected clinical conditions.

Temporomandibular Joint Arthroplasty with Human Amniotic Membrane - Case Report

Bauer F, Hingsammer LM, Wolff KD, Kesting MR. 18 March 2013

 2013;13:e17. Epub 2013 Mar 18.

Abstract

This case reports the usage of human amniotic membrane combined with a costochondral graft as an interpositional material in temporomandibular joint reconstruction for the first time in humans. Because of the favorable outcome 20 months postoperatively, it has to be considered as an approach bringing to light the antiadhesive potential of amniotic membrane. This case report must be regarded as initial spadework and should motivate other institutions to intensify their clinical research in this field. Because of the fact that currently used interpositional materials do not prevent the recurrence of temporomandibular joint ankylosis sufficiently, it is of great interest to establish a proper therapeutic intervention fulfilling these demands. Furthermore, the demonstrated antiadhesive properties of amniotic membrane highlight its multifaceted field of application. Nevertheless, further studies have to prove the findings reported in our case.

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

Siemionow M, Uygur S, Ozturk C, Siemionow K. 03 May 2014

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

Yury Ostrovsky, Siarhei Spirydonau, Mikalai Shchatsinka and Aliaksandr Shket 19 January 2015

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.

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

Saphenous vein graft intervention: status report 2014

Soverow J, Lee MS. 06 December 2014

 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.

I.B. Kar, A.K. Singh, P.C. Mohapatra, P.K. Mohanty, S. Misra 30 November 2014

 International Journal of Oral & Maxillofacial Surgery  

Abstract

The aim of this study was to evaluate the clinical outcome of the surgical repair of oral mucosal defects using cryopreserved human amniotic membrane (HAM) as a graft material. Thirty-four patients with precancerous lesions such as leukoplakia, erythroplakia, and verrucous hyperplasia were included. Fresh amniotic membrane was obtained from women undergoing elective caesarean section; the membrane was cleaned, prepared in antibiotic solutions, and preserved at -80 °C. Results suggested that HAM promotes healing and epithelialization without specific complications. Thus we conclude that the use of HAM gives promising results in the repair of post-surgical oral mucosal defects.
