防止椎板切除术后硬脊膜外瘢痕粘连的实验研究 总被引:43,自引:2,他引:41
作者在4个平面间隔切除11只山羊的椎板,分别用硅胶膜、自体游离脂肪片、带蒂肌肉瓣覆盖硬脊膜,一处平面作空白对照。术后4个月组织学检查,结果显示,硅胶膜后方有少许瘢痕组织增生,间质中有炎细胞灶状浸润,硅胶膜与硬膜囊无瘢痕形成,新形成的椎管后壁光滑,硬膜囊无受压;脂肪片被纤维组织取代,周围纤维组织增生轻微,形成菲薄之纤维膜,与硬脊膜容易分离;带蒂肌肉瓣周围形成较多瘢痕与硬脊膜粘连重,肌肉瓣已完全纤维化,空白组形成瘢痕最多,与硬脊膜粘连最重。术后硬膜囊矢状径以硅胶膜组最大,脂肪片组次之,带蒂肌肉瓣组再次之,空白组最小。作者认为,硅胶膜与脂肪片能明显防止椎板切除术后纤维瘢痕粘连对硬膜囊的压迫,在支架诱导作用方面,硅胶膜优于脂肪片,在生物相容性方面脂肪片优于硅胶膜。带蒂肌肉瓣优于对照组,但不及前两者。 相似文献

OBJECTIVE: Although the mechanism by which cranial subdural hematomas form is known, the formation of spinal subdural hematomas is less clearly defined. The aim of this study was to identify vessels that can be found in the dural sac and whose rupture might lead to the formation of spinal subdural hematomas. MATERIAL AND METHOD: The dura mater, subdural space, and the arachnoid mater were studied in samples of dural sac taken from the eleventh thoracic vertebra to the fifth lumbar vertebra. The samples were taken from 3 fresh cadavers. Some were fixed in glutaraldehyde, dehydrated, and metallized with gold for scanning electron microscopy. Others were fixed in glutaraldehyde, treated with osmium tetroxide, and embedded in an epoxy resin for observation under a transmission electron microscope. RESULTS: Small hematomas--some on the internal surface of the dura mater and others surrounding nerve roots--were found within a thin, translucent arachnoid mater. Vessels measuring up to 100 microm were found within the dura mater, between its inner and outer laminae. Venules and capillaries were observed in the subdural space and in the arachnoid mater. CONCLUSIONS: Vessels are present between the laminae of the dura mater, in the subdural space, the arachnoid mater, and in spinal nerve roots. The rupture of these vessels could account for the formation of spinal subdural hematomas. 相似文献

STUDY DESIGN.: A dissection-based study of 30 embalmed cadavers. OBJECTIVE.: To determine the morphology and morphometry of the dorsal meningovertebral ligaments in the lumbosacral segments and to discuss their clinical significance. SUMMARY OF BACKGROUND DATA.: Postoperative cerebrospinal fluid leakage is associated with longer hospital stays and significant implications for the patient, the surgeons, and society as a whole. To protect the dural sac during lumbar surgery, knowledge of the surgical anatomy of the dorsal meningovertebral ligaments is crucial. METHODS.: A total of 30 adult embalmed cadavers (52-70 yr of age; mean age of 64 yr) were used. The vertebral canal was divided to expose the dural sac and the spinal nerve roots, and the spinal cord was removed. The morphology, quantity, and attachment of the dorsal meningovertebral ligaments in the lumbosacral region were observed, and the length, width, or diameter and thickness of the ligaments were measured with vernier calipers. RESULTS.: The dorsal meningovertebral ligaments in the lumbosacral region connect the dura to the ligamenta flava or the lamina. The number of the attachment points on the ligamenta flava was relatively larger than that on the lamina, and the occurrence rate of dorsal meningovertebral ligaments was 97% at L5-S1. The thickest ligaments were observed at the L5 and S1 vertebrae. The length of the ligaments varied from 5.16 to 40.24 mm, and the ligaments extended caudally from their origin on the dura to their attachment to the lamina or the ligamentum flavum. The morphology of the dorsal meningovertebral ligaments was divided into 5 types: strip type, cord type, "Y"-shaped type, grid type, and thin slice type. CONCLUSION.: The dorsal meningovertebral ligaments may contribute to dura laceration and epidural hemorrhage during flavectomy and laminectomy, and an appreciation of this relationship might help reduce the risk of such complications. 相似文献

OBJECTIVE: The aim of this experimental study was to create a new focal venous infarction model in rats. METHOD: 20-male Sprague-Dawley rats were used in this experiment. Unilateral frontal strip craniectomy was done in front of the coronal suture. Frontal veins were observed by using the operative microscope. In this study we used the bipolar coagulation method over the transparent dura mater for occlusion of the bridging veins for venous infarction. Specimens were evaluated by histopathological techniques. RESULTS: Unilateral frontal hemispheric swelling, midline shift, brain edema, subcortical petechial hemorrhage, hemorrhagic infarction and necrosis were the histopathological findings on microscopic examination. CONCLUSION: Our results revealed that the bipolar coagulation method over the transparent dura mater for occlusion of the unilateral frontal cortical veins for venous infarction might be a new experimental model in the evaluation of brain damage after disturbance to the venous circulation. 相似文献

Background contextThe dural sac is anchored within the vertebral canal by connective tissue called meningovertebral ligaments in the epidural space. During flavectomy and laminectomy, inadvertent disruption of the dorsal meningovertebral ligaments may lead to dura laceration and cerebrospinal fluid (CSF) leaks. All the described dorsal meningovertebral ligaments were located in the lumbar region. A rare study is available about dorsal meningovertebral ligaments of the cervical spinal dura to the adjacent vertebrae.PurposeTo identify and describe the dorsal meningovertebral ligaments at each cervical level and discuss their clinical significance.Study designA dissection-based study of 22 embalmed cadavers.MethodsThe anatomy was studied in 22 whole cervical cadavers (11 females, 11males), prepared with formaldehyde, whose ages at the time of death ranged from 55 to 78 years. The vertebral canal was divided to expose the dural sac and the spinal nerve roots. At all levels of the cervical vertebra, the morphology, quantity, origin, insertion, and spatial orientation of the dorsal meningovertebral ligaments were determined and the length, width or diameter, and thickness of the ligaments were measured with vernier calipers.ResultsThe dorsal meningovertebral ligaments in the cervical region anchored the posterior dural sac to the ligamentum flavum or laminae. The number of attachment points on the ligamentum flavum was relatively larger than that on the lamina, and the occurrence rate of dorsal meningovertebral ligaments was 100% at C1–C2 and C4––C5. The thickest ligaments were observed at the C1 and C2 vertebrae. The length of the ligaments varied from 1.50 to 35.22 mm, and the orientation of the ligaments mostly was craniocaudal. The morphology of the dorsal meningovertebral ligaments was divided into four types: strip type, cord type, grid type, and thin slice type.ConclusionsIn the cervical spine, the dorsal meningovertebral ligaments exist between the posterior dural sac and the ligamentum flavum or lamina. The dorsal meningovertebral ligaments may be of clinical importance to surgeons. Dissecting the dorsal meningovertebral ligaments before the cervical flavectomy and laminectomy may be an important step in reducing postoperative dura laceration and CSF leaks, which may result in significant benefits for patients and health-care organizations. 相似文献

OBJECTIVE: Sacrifice of a bridging vein in the cranial base occasionally may cause significant postoperative morbidity. We report a simple method for preserving large bridging veins of the cranial base by reflecting the dura when a subtemporal or transsylvian approach is used. METHODS: In the subtemporal approach, when a larger bridging vein enters the dura attached to the bone of the temporal base before it empties into the dural sinus, the dura is dissected widely from the bone and is cut vertically toward the medial side of the temporal base in front of the entrance of the vein into the dura. The dura, which includes part of the entrance and interdural course of the vein, is reflected and retracted over the brain. In the transsylvian approach, when the bridging segment of the superficial sylvian vein becomes taut because of retraction of the temporal lobe, the dura is incised along the sphenoid ridge and is dissected and freed from the sphenoid bone. RESULTS AND CONCLUSION: This dura-reflecting technique facilitates brain retraction without exerting tension on the bridging vein of the cranial base and is expected to help avoid injury to bridging veins during neurosurgical procedures. 相似文献

Several anterior and posterior methods are today available for stabilization of the cervical spine. Factors such as level and degree of instability, method of decompression, bone quality, length of fixation and safety factors influence the choice of method for a particular patient. The use of laminar hooks in the cervical spine has been restricted by fear of cord compression with the potential of tetraplegia. The aim of the present study was to assess the safety and determine the anatomical relation between hooks inserted in the cervical spinal canal and the dura and spinal cord. Thirteen cadavers from seven women and six men with no evidence of cervical spine disorder were included. The mean age was 81.3 years (range 65-101 years). The cervical spine was instrumented with cervical Compact Cotrel Dubousset hooks and rods. The effect of the hook on the dura was studied by myelography in nine cadavers. The deformation of the dural sac was quantified by measurement of the maximal width of the indentation of the contrast column at each level. A CT myelography scan was obtained in three cadavers. The ratio between the distance of maximal hook intrusion into the spinal canal and the canal diameter in the direction of the hook was calculated. The relation between inserted hooks and the spinal cord and dura was documented in a fresh cadaver studied with CT myelography. A hemilaminectomy was performed at all levels in three cadavers with direct visual inspection and photography of the hook sites before and after excision of the dura. A dural deformation of 2 mm or less, as observed by myelography, was found at four out of 77 (5%) hook sites. The deformation was caused by a supralaminar hook at C3, C6 and C7 and by an infralaminar hook at C6. The mean hook intrusion in the spinal canal, as observed on CT, was 27% (range 8-43) of the canal diameter. On visual inspection, 14 out of 18 hooks were in contact with the dura. After removal of the dura, two out of the 18 hooks in the same cadaver were in contact with the spinal cord. However, no deformation of the cord was observed. To our knowledge this is the first study systematically documenting the relation between hooks and the spinal cord in cadavers. In 95% of the hooks no deformation of the dural sac was observed and there was no evidence of spinal cord deformation. From an anatomical point of view, laminar hook instrumentation can be considered a safe procedure. The study shows, however, that hooks inserted in the cervical spine have a close anatomical relationship with the neuraxis, and at stenotic levels the use of other techniques is therefore recommended. 相似文献
