TL;DR: It is difficult to assess the natural history of intracranial vascular malformations because they are varied in nature, they are frequently silent clinically, and they are often treated when they are discovered, and untreated lesions are not often followed in an organized way.
Abstract: It is difficult to assess the natural history of intracranial vascular malformations because they are varied in nature, they are frequently silent clinically, they are often treated when they are discovered, and untreated lesions are not often followed in an organized way. Capillary telangiectasias are usually occult lesions of no clinical significance. Cavernous hemangiomas may cause seizures and may bleed, but the approximate yearly risks of bleeding and of death have not been determined. Venous angiomas seldom cause symptoms, with the exception that those in the cerebellum seem to have a propensity to bleed. Intracranial dural arteriovenous malformations (AVMs) may bleed and may cause brain injury if there is insufficient outflow into a dural venous sinus. The dural AVMs that drain into the cavernous sinus have a more benign course than those that drain into the transverse or sigmoid sinus. The aneurysm of the vein of Galen presents a different clinical picture and threat to health according to whether the patient is a neonate, an infant, or an older child. The AVM of the brain encountered in the adult usually presents with hemorrhage or seizures. An unruptured AVM has approximately a 2 to 3% risk of bleeding per year, with about a 1% risk of death per year. The mortality rate of the first hemorrhage is about 10%. Among the survivors, there is about a 6% chance of rebleeding during the 1st year and then approximately a 2 to 3% risk of bleeding per year subsequently. The mortality rate associated with a second hemorrhage is about 13%, and for subsequent hemorrhages the mortality is roughly 20%.

TL;DR: Results and complications are reviewed in 27 patients whose symptomatology had progressed under conservative management; 22 of these cases harbored primary lesions and five had recurrences.
Abstract: Arteriovenous malformations (AVM's) of lateral and sigmoid sinuses are acquired lesions evolving from a previously thrombosed dural sinus. Their natural history is usually that of gradual progression and hence surgery is frequently necessary. The preferred surgical treatment is complete excision coupled with packing of the sigmoid sinus. The operative approach is illustrated and discussed in detail. Results and complications are reviewed in 27 patients whose symptomatology had progressed under conservative management; 22 of these cases harbored primary lesions and five had recurrences. There were 22 excellent, one good, and two poor results (both of the latter from blindness that preceded surgery). There were two deaths, both in patients previously operated on with incomplete removal or obliteration of the AVM by attempted embolization.

TL;DR: In this paper, a method for the suppression or prevention of pain, movement disorders, epilepsy, cerebrovascular diseases, autoimmune diseases, sleep disorders, autonomic disorders, urinary bladder disorders, abnormal metabolic states, disorders of the muscular system, and neuropsychiatric disorders in a patient.
Abstract: A method is provided for the suppression or prevention of pain, movement disorders, epilepsy, cerebrovascular diseases, autoimmune diseases, sleep disorders, autonomic disorders, urinary bladder disorders, abnormal metabolic states, disorders of the muscular system, and neuropsychiatric disorders in a patient. The method comprises positioning at least one electrode adjacent to or around an implantation site selected from the group consisting of the patient's: superior sagittal sinus; confluence of sinuses; occipital sinus; sigmoid sinus; transverse sinus; straight sinus; inferior sagittal sinus; the dura adjacent the superior sagittal sinus, confluence of sinuses, occipital sinus, sigmoid sinus, transverse sinus, straight sinus, or inferior sagittal sinus; or falx cerebri. The electrode is then activated to apply an electrical signal to the at least one implantation site. In a further embodiment of the invention used to treat the same conditions, the electrode dispenses a medication solution or analgesic to the implantation site. A method is also provided for surgically implanting the electrodes adjacent to or around the implantation site.

TL;DR: The article proposes new refinements in the classification of types C and D tumors and describes in detail the technique of blind sack closure of the external auditory canal, double ligation of the sigmoid sinus and the use of a special infratemporal fossa retractor.
Abstract: The surgical experience with 74 glomus tumors of the temporal bone is presented. The article proposes new refinements in the classification of type C and D tumors and describes in detail the technique of blind sack closure of the external auditory auditory canal, double ligation of the sigmoid sinus and the use of a special infratemporal fossa retractor. The postoperative treatment and intraoperative management of the internal carotid artery, facial nerve and cranial nerves IX, X, XI and XII including the technique and results of a new type of V-VII anastomosis are discussed.

TL;DR: Eleven patients with dural fistulas involving the transverse and sigmoid sinuses were treated by transvenous embolization with coils or liquid adhesives: four of these patients had complete obliteration of their fistulas and there was 95% reduction in the remaining three.
Abstract: Eleven patients with dural fistulas involving the transverse and sigmoid sinuses were treated by transvenous embolization with coils or liquid adhesives. Seven patients underwent preoperative embolization of the external supply followed by direct surgical exposure of the sinus: liquid adhesives were used in four patients and coils in the remaining three. Four of these patients had complete obliteration of their fistulas and there was 95% reduction in the remaining three. Four patients had transvenous placement of coils from a transfemoral approach. In three, the ipsilateral sigmoid sinus was thrombosed and a contralateral approach across the torcular herophili was used. Coils were used in all four patients; one patient also had liquid adhesives placed within the sinus. Complete cure was achieved in one patient, 95% reduction in another, and 50% and 40%, reductions in the remaining two. Two transient complications occurred, one related to venous occlusion secondary to liquid adhesives and another related to transient occlusion of the vestibular aqueduct. Obliteration of dural fistulas involving the transverse and sigmoid sinuses can be achieved by placement of embolic material within the involved sinus from a transvenous approach; both coils and liquid adhesives can achieve this goal.
