چکیده
Magnetic resonance angiography (MRA) or magnetic resonance venography (MRV) can be used as a first line investigation of intracranial vascular disease. It is an alternative to invasive intra-catheter angiography that was once the mainstay for the investigation of intracranial vascular disease. MRA/MRV may use a contrast agent, gadolinium, which is non-iodine-based, for better visualization. It can be used in patients who have history of contrast allergy and who are at high risk of kidney failure.

Pulsatile tinnitus.
Pulse-synchronous tinnitus suggests a vascular etiology and is deemed rare by the otologic literature. During the period 1978-1985 we evaluated 20 patients with the sole or initial complaint of pulsatile tinnitus. Fourteen patients had objective pulsatile tinnitus, perceived by the patient and the examiner alike, and 6 had subjective pulsatile tinnitus, perceived by the patient only. Angiograph...
متن کاملCurrent Status of the Application of Intracranial Venous Sinus Stenting
The intracranial venous sinus is an important component of vascular disease. Many diseases involve the venous sinus and are accompanied by venous sinus stenosis (VSS), which leads to increased venous pressure and high intracranial pressure. Recent research has focused on stenting as a treatment for VSS related to these diseases. However, a systematic understanding of venous sinus stenting (VS-S...
متن کاملVascular etiology of intracranial hypertension.
We would like to thank the author of the Letter to the Editor for taking the time to comment on our study. Indeed Degnan et al. recommended the MR venography for detecting cerebral venous sinus thrombosis, but in cases of pseudotumor cerebri. They wrote: “some cases of IIH (idiopathic intracranial hypertension) have identifiable etiology, such as dural venous stenosis, which has been implicated...
متن کاملIntracranial hypertension.
Intracranial hypertension is not a definitive diagnosis, but rather a syndrome that may result from a number of neurologic and systemic disorders. Intracranial hypertension refers to prolonged elevation of intracranial pressure, generally above 200 mm H2O. This condition may be recognized by the various clinical signs and symptoms that are manifest in most patients, including headache, papilled...
متن کاملEVALUATION OF CRANIALIZATION TECHNIQUE IN T HE TREATMENT OF FRONTAL SINUS FRACTU RES
Frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. There is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. In this condition, communication occurs between the contaminated space of the air sinus and the intr...
