骑跨上矢状窦硬膜外血肿的临床特点与治疗体会(附13例报告) 总被引:1,自引:0,他引:1
骑跨上矢状窦硬膜外血肿在临床上可归为一组特殊类型硬膜外血肿.其出血来源、病情发展、手术方式均与其它种类不同,术中出血凶猛、死亡率高。特别是顶部骑跨矢状窦硬膜外血肿,在血肿较小时,常规轴位扫描可见不到血肿,即使有血肿显示.也很难窥其全貌.不出现常见的双凸形高密度影,易发生漏诊或误诊。2001年-2006年我科收治13例骑跨上矢状窦硬膜外血肿病例。本文结合文献,对其临床特点、产生机制、手术方式及注意事项进行分析探讨。 相似文献

Summary A 62-year-old man suffered from progressive dementia for the last 5 years of life. Angiography disclosed draining of multiple extracranial, galeal arteries directly into the superior sagittal sinus with retrograde filling of cerebral veins. At necropsy there was arterialization of the walls of the sinus and a multichannelled lumen in its middle third. The sinus was not distended, the dura normal, and no angioma was found. The leptomeninges and the cerebral white matter contained excessively distended veins, some with thickend fibrotic walls. Many arteries in the cerebral white matter were mineralized. There were widespread patches of incomplete demyelination about these abnormal vessels. The lesion was classified as a developmental anomaly with direct shunting of extracranial arteries into the superior sagittal sinus.
Zusammenfassung Fallbericht eines 62jährigen Mannes, der während der letzten 5 Jahre an einer progredienten Dementia litt. Angiographische Untersuchungen zeigten multiple Shunts extracranieller Galeaarterien direkt in den Sinus sagittalis superior mit retrograder Füllung der Venen der Großhirnhemisphären. Bei der Autopsie fand sich Arterialisation der Wand des Sinus sagittalis superior mit multiplen Lumina in seinem mittleren Drittel. Der Sinus war nicht dilatiert, die Dura normal, und kein eigentliches Angiom wurde gefunden. Dilatierte Venen in den Leptomeningen und in der hemisphärischen weißen Substanz zeigten gelegentlich verdickte fibrotische Wandungen. Arterien der weißen Substanz waren vielfach verkalkt. Derartige abnormale Gefäße waren von ausgedehnten Herden unvollständiger Entmarkung umgeben. Die Läsion wurde als eine Entwicklungsstörung klassifiziert, charakterisiert durch multiple direkte Shunts in den Sinus sagittalis superior.相似文献

The permeability of the wall of the superior sagittal sinus of the cat has been studied using horseradish peroxidase (HRP) as an exogenously applied tracer. Cats were given intracisternal or intravascular injections of HRP before being perfused transcardially for examination of sinus tissues with the electron microscope. Tissues were processed with diaminobenzidine to reveal peroxidase activity. A diffusion barrier to the protein tracer was seen to occur at the level of the arachnoid mater. When injections of HRP were made into the cisterna magna, the protein was able to course through the subarachnoid space surrounding the sinus, and sequestration of the tracer was seen in deep cell layers of the arachnoid mater. However, a series of zonulae occludentes at more apical levels of the arachnoid prevented the tracer from penetrating intercellularly to the level of the dura mater. Conversely, when HRP was given intravascularly, the protein penetrated intercellular spaces of the dura mater and apical levels of the arachnoid mater, stopping at the level of the zonulae occludentes of the arachnoid. This barrier layer appears to be continuous with the arachnoid barrier layer which prevents diffusion of large molecules through the arachnoid mater over the brain convexities. 相似文献

ObjectiveWe present our experience with surgery of parasagittal and falcine meningiomas invading the superior sagittal sinus with special consideration of the surgical complications and the incidence of tumour recurrence.Materials and methodsThe analysis included 37 patients with parasagittal and falcine meningiomas invading the superior sagittal sinus. In 13 cases, the sinus was ligated and resected with tumour. In 14 cases, the sinus was entered with the goal of tumour resection and the sinus was reconstructed, while in 10 patients the sinus was not entered and the remaining residual tumour was observed for growth.ResultsOut of 13 patients after radical resection of the tumour and invaded part of sinus, 9 revealed haemodynamic complications: venous infarction (4), significant brain oedema (3) and hypoperfusion syndrome (2). 2 out of 14 patients after resection of the tumour from the lumen of the superior sagittal sinus with subsequent sinus repair developed venous infarction after surgery. Among 27 patients after radical tumour excision the remote follow-up revealed recurrence in 2 patients. There were no significant haemodynamic complications in none of 10 cases, in which the residual tumour was left after surgery in the superior sagittal sinus. In this group, 3 cases were subjected to early post-operative radiotherapy and local recurrence was observed in 4 patients.ConclusionsThe aggressive surgical treatment of meningiomas infiltrating the superior sagittal sinus is associated with a high surgical risk. The incidence of recurrence of these tumours increases significantly in the case of non-radical excision of the tumour. 相似文献
