Intravascular occlusion by various catheterization techniques was used to treat 27 cases of carotid-cavernous fistula, giant intracavernous aneurysm, and cerebral or dural arteriovenous malformation. Several case reports are presented. The detachable balloon technique proved valuable in the treatment of traumatic carotid-cavernous fistula and giant aneurysm. Calibrated-leak balloon catheterizat...

We assessed the feasibility of creating an experimental arteriovenous malformation model in swine by diverting and increasing blood flow through bilateral retia mirabilia. This was achieved by surgical formation of a large right-sided carotid-jugular fistula, in combination with endovascular occlusion of several neck arteries ipsilateral to the fistula. Using this technique, 11 of 13 swine demo...

A 9-year-old girl with a several-month history of unilateral intermittent headaches presented to the hospital with worsening headaches and unsteadiness. Neurologic exam was positive for a mild right hemiparesis and right homonymous hemianopsia. Noncontrast computed tomography revealed an engorged sagittal and straight sinus with prominent cortical veins concerning an arteriovenous malformation ...

During a 3 year period, 21 patients with spinal cord vascular malformations involving the anterior spinal artery were treated by embolization through this artery. Of four cases of extramedullary arteriovenous fistula, two patients embolized at an early stage showed excellent results, whereas results were mediocre in two patients who were paraplegic at embolization. Of 17 cases of intramedullary...

Pulsatile tinnitus is a rarely occurring symptom of vascular origin. Most frequently, the symptoms are due to an arteriovenous malformation, to a tumor of the jugular glomus or to a local arterial stenosis. A 39-yr-old Korean male suffering from pulsatile tinnitus of the left ear was diagnosed to have dural arteriovenous malformation of the jugular bulb. Magnetic resonance imaging and angiograp...

The incidence of aneurysmal subarachnoid hemorrhage is about 10-11 cases per 100,000 inhabitants. The true incidence of multiple aneurysms is not known, however, according to previous studies it may vary between 20% and 30%. The association of arteriovenous malformation and cerebral aneurysm is well documented and varies between 20% and 30%. A case is described of a 47-year-old female presentin...

BACKGROUND AND PURPOSE Patients with hereditary hemorrhagic telangiectasia (HHT) are at risk for developing cerebral vascular malformations and pulmonary arteriovenous fistulae. We assessed the risk of neurological dysfunction from these malformations and fistulae. METHODS Three hundred twenty-one consecutive patients with HHT seen at a single institution over a 20-year period were studied. A...

Epileptic seizures are a common presentation in patients with newly diagnosed brain arteriovenous malformations, but the pathophysiological mechanisms causing the seizures remain poorly understood. We used magnetic resonance imaging-based quantitative cerebrovascular reactivity mapping and conventional angiography to determine whether seizure-prone patients with brain arteriovenous malformation...

Introduction:Intracranial hemorrhage (ICH) is divided into two traumatic and non-traumatic categories. The present study sought to investigate the anatomical properties of non-traumatic intracranial hemorrhage in Kerman, Iran. Method:A total of 305 non-traumatic ICH cases were chosen in Shafa medical center. Data from patients’ files and CT scan images, including demographic factors and type o...

Spontaneous regression of cerebral arteriovenous malformation is rare and less than hundred cases have been reported in literature. The authors report a case 64 year/male who was diagnosed with which found to undergo spontaneous on repeat imaging. phenomenon.
