Tissue engineering, using either polymer or biological based scaffolds, represents the newest approach to overcoming limitations of small diameter prosthetic vascular grafts. Their disadvantages include thromboembolism and thrombosis, anticoagulant related haemorrhage, compliance mismatch, neointimal hyperplasia, as well as aneurysm formation. This current review represents an overview about pr...

OBJECTIVE Posterior fossa decompression with duraplasty (PFDD) is often used for Chiari malformation type I (CM-I), but outcomes associated different dural graft materials are not well characterized. In this meta-analysis, the authors examined complication rates and after PFDD CM-I autografts four types of nonautologous grafts. METHODS A literature search numerous electronic databases (Ovid Med...

Introduction: Structural bone allografts are frequently used to reconstruct bone defects in the extremities as well as for spinal fusion surgery. Failed healing at the graft-host junction is one of the most frequent complications of allograft surgery. However, the factors that regulate healing and graft incorporation remain poorly understood. The goal of these studies is to examine the molecula...

Coaxial autografts of skeletal muscle which had been frozen then thawed were used to repair injured digital nerves in eight patients. Assessment from three to 11 months after operation showed recovery to MRC sensory category S3+ in all but one patient, an excellent level of recovery. We conclude that bespoke muscle grafts treated and used in this way may offer significant advantages over conven...

The article presents the modern treatment with stem cells in the reconstruction of ocular surface. The turnover of the stem cells, the location in the limbus areas, the importance of limbal stem cells presence, the clinical appearance of stem cell deficiency, investigations method for this illness and the management of stem cell deficiency (artificial lacrimal tear drops, mini scleral contact l...

Methods for handling burn wounds have changed in recent decades. Increasingly, aggressive surgical approach with early tangential excision and wound closure is being applied leading to improvement in mortality rates of burn victims. Autografts from uninjured skin remain the mainstay of treatment. Autologous skin graft, however, has limited availability and is associated with additional morbidit...

In the present work, the repairing response of the iliac arterial wall is studied after carrying out autografts in segments of these vessels. The formation of the intimal hyperplasia, which occurred in all the cases, was followed at the biochemical level (tritium thymidine incorporation) and with light and electron microscopy. The adventitial layer showed great activity during the repairing pro...

Current techniques in tissue engineering may offer a choice regarding the reconstructive strategies of peripheral nerves. Schwann cell cultures are to be considered an appropriate option in the reconstruction of peripheral nerve and spinal cord large defects. Schwann cells availability from peripheral nerve autografts creates a great benefit concerning their usefulness in the nervous autogenic ...
