(1) We describe 10 patients with cerebral venous thrombosis: two had protein S deficiency, one had protein C deficiency, one was in early pregnancy, and there was a single case of each of the following: dural arteriovenous malformation, intracerebral arteriovenous malformation, bilateral glomus tumours, systemic lupus erythematosus, Wegener's granulomatosis, non-Hodgkin's lymphoma.
(2) In order to study cerebrospinal fluid (CSF) absorption across the dural sinus wall, the effect of CSF pressure (recorded from the cisterna magna) on dural venous pressure (recorded from the transverse sinus) was investigated in groups of rats at 2, 10, 20, and 31 days after birth and in adulthood.
(3) Direct visualization of the intercavernous sinuses on contrast-enhanced MR images may serve as an ancillary sign for the diagnosis of carotid-cavernous or carotid-dural fistulas near the sella.
(4) They were 3 patients with Arnold-Chiari malformation with syringomyelia, 3 with syringomyelia and 2 with "narrowed dural tube".
(5) Moderate or marked brain and dural enhancement was noted in nearly every patient imaged within 3 months of surgery, but all brain enhancement was gone by 1 year.
(6) In addition, it proposes a modification of the standard dural closure that may reduce the incidence of contributory adhesive arachnoiditis by the creation of a capacious cerebrospinal fluid space about the neural plaque.
(7) Dural attachment is frequent, calcifications are not.
(8) Left angiography, performed in August, 1975, revealed a dural arteriovenous malformation, which was supplied by enlarged left middle meningeal artery, occipital artery, meningohypophyseal artery and superior cerebellar artery and was draining into the left sigmoid sinus.
(9) At this stage any attempt at definitive removal of diseased tissue would necessarily result in a larger dural defect at a time when local disease and systemic illness present unsuitable conditions for reparative procedures.
(10) The authors report a case of growing skull fracture in which watertight dural closure was difficult at the first operation because a dural defect extended deep into the middle fossa.
(11) The intraoperative dural damage did not require specific treatment, while the patients with discitis responded readily with antibiotics.
(12) The third cerebral angiography after right SDP (synangio-dural plasty), 49 months after the initial angiography, revealed, in the right angiography, newly formed anastomotic vessels perfusing the middle cerebral artery region via the extracerebral arteries and in the left cerebral angiography, and an increased obstruction of the ICA terminal portion, transdural anastomosis via the extracerebral arterial system, and a decrease of moyamoya vessels in the basal area.
(13) In meningiomas, a flat, contrast-enhancing, probably dural structure adjacent to the tumor can occasionally be observed on Gadolinium-DTPA enhanced MR images.
(14) In an experimental model using the New Zealand White Rabbit the materials were implanted into dural defects of dimensions 1.7 cm by 1 cm.
(15) The authors present a patient who developed an acute hemorrhage around a Silastic dural substitute 13 weeks after excision of a meningioma and implantation of the graft.
(16) The classic concept that DAVMs arise in direct relationship with the dural sinuses is limited.
(17) The frequent concurrent venous abnormalities are easily understood as (a) retention of fetal anatomical features and (b) frequent occlusions of the dural sinuses of the posterior fossa, especially the sigmoid sinuses.
(18) Thirteen (72%) of the 18 meningiomas exhibited the finding adjacent to the dural attachments.
(19) No post-dural puncture headache was observed in the CSA group.
(20) The clinical picture of dural arteriovenous malformations cannot be explained on the basis of degree of arteriovenous shunting in many cases.
Jural
Definition:
(a.) Pertaining to natural or positive right.
(a.) Of or pertaining to jurisprudence.
Example Sentences:
(1) Under Islamic law, embryo transfer is illegal insofar as it involves artificial insemination of the donor by the husband; temporary maternity by the donor is a jural concept that has no place in Islamic family law.
(2) Despite appearances, the delimitation of the so-called "corporate groups"--for example, an African lineage--is neither more "natural" nor more jural than that of the society which contains them.
(3) They gain their power by relying on certain unquestionable assumptions which, although beyond everyday jural relationships, articulate such relationships.
