Anatomic and Biomechanical Properties of Human Lumbar Dura Mater

Anesthesia & Analgesia, 1993
Determinants of dural defects subsequent to deliberate or accidental dural puncture include the equipment, techniques, and the inherent anatomic and biomechanical properties of dura mater. These properties were studied in specimens of human and canine lumbar dura mater in an attempt to delineate the structure of the tissue and to characterize its ...

Physical and chemical processing for a human dura mater substitute

Biomaterials, 2002
Allogenic human fascia lata used in neurosurgery, as dura mater substitute, can be associated with a risk of viral and bacterial transmission. Chemical and physical procedures, developed to inactivate virus and bacteria, have been applied to fascia lata. The aim of this study consists in the evaluation of the biological properties of this treated graft.

Bladder Exstrophy. Primary Reconstruction with Human Dura Mater

British Journal of Urology, 1981
SUMMARY— A new surgical technique for primary reconstruction of bladder exstrophy is described. Human cranial dura mater is used as an alloplastic free graft to replace the missing anterior bladder wall. The technique has been successfully applied to 8 patients and the early achievement of good bladder capacity ...

Histomorphometry of mast cells in the convexity of human intracranial dura mater

Journal of Anatomy, 2021
AbstractMast cells, known as pro‐inflammatory effector cells, are immunocytes present in the meninges and may be involved in the pathophysiology of migraine. This study aims to evaluate the histomorphometric parameters of mast cells located in the convexity of the human intracranial dura mater.

EXPERIENCE WITH LYOPHILIZED HUMAN DURA MATER FOR URETHRAL STRICTURES

The Journal of Urology, 1998
We report our results using lyophilized human dura mater for urethral strictures.The results of 131 urethroplasties using lyophilized human dura mater grafts were reviewed. The etiology of the stricture was unknown in most cases and 44.3% had not been previously treated. Mean stricture length was 10 cm.

Ultrastructure of the human spinal arachnoid mater and dura mater.

Journal of anatomy, 1997
Human spinal dura and arachnoid, obtained during neurosurgical operations, were studied by transmission electron microscopy. The ultrastructure of spinal meninges largely conformed to the morphology of the cranial meninges, but some minor differences were detected.

Local Mechanical Anisotropy in Human Cranial Dura Mater Allografts

Journal of Biomechanical Engineering, 1998
Human cranial dura mater (CDM) allograft’s success as a repair biomaterial is partly due to its high mechanical strength, which facilitates its ability to form water-tight barriers and resist high in-vivo mechanical loads. Previous studies on CDM allograft mechanical behavior used large test specimens and concluded that the allograft was mechanically ...

Revision Myringoplasty with Solvent‐Dehydrated Human Dura Mater (Tutoplast)

Otolaryngology–Head and Neck Surgery, 2001
OBJECTIVESSeveral grafting materials have been used in the reconstruction of the perforations of the tympanic membrane. The use of dehydrated dura homografts as a substitute for the tympanic membrane has not been fully documented. On the other hand, revision surgery is more critical in terms of patients' expectations.

[Urethroplasty with lyophilized human dura mater].

Archivos espanoles de urologia, 1995
This article reports our experience with lyophilized human dura in the treatment of complex urethral stenosis.Seven patients with iatrogenic/inflammatory urethral stricture underwent a 13 cms long x 1.5 cms wide medial urethral augmentation.During a mean follow-up of 23 months, good results accounted for 85.7%.Lyophilized dura patches constitute a ...

The mechanical properties of human dura mater and the effects of storage media

Clinical Physics and Physiological Measurement, 1981
Data are presented on the tensile strength and ultimate extensibility of human dura mater. Experiments were performed, prior to, and after, storage in glycerol. The results indicate that storage in glycerol has a small effect on the measured mechanical properties, but this was not statistically significant. In addition, storage in saline after glycerol
