An arteriovenous malformation or dural arteriovenous fistula is an abnormality of the blood vessels that causes shunting of blood from an artery to a vein, bypassing normal tissue. This high-flow system may pose a risk for bleeding.
Some brain aneurysms can be closely observed with periodic surveillance imaging. For aneurysms that require treatment, endovascular therapy can be performed from inside the blood vessel.
Carotid artery narrowing is a known cause of ischemic stroke. Treatment options for selected patients include a minimally invasive endovascular approach to restore normal blood flow.
A carotid cavernous fistula can develop after trauma or spontaneously. Symptoms can include swelling and injury to nerves that control eye function.
A diagnostic catheter cerebral or spinal angiogram is a procedure that is performed to acquire high-resolution images of the blood vessels of the head and neck or spine. This is also the foundation to all endovascular interventional procedures.
The impact of ischemic stroke upon healthcare in the United States is staggering. Extensive research has attempted to unlock methods of safely restoring blood flow to the brain and protect patients from progression to permanent brain damage.
Epistaxis, or excessive bleeding from the nose, can be caused by various underlying conditions.
Cushing syndrome results from excess production of the hormone cortisol. The release of cortisol is controlled by adrenocorticotropic hormone (ACTH), which can be produced in several locations throughout the body.
Ischemic stroke can have multiple causes including clot migration from the heart, narrowing of arteries in the neck, and plaque buildup leading to narrowing of the blood vessels in the brain, which is known as intracranial atherosclerotic disease.
Intracranial venous sinus abnormalities can obstruct the outflow of blood from the head. In some patients who have chronically elevated intracranial pressures, venous outflow obstruction may be a related finding.
Tumors can be highly vascularized structures and this large amount of blood vessels can lead to excessive bleeding during surgical removal. In some cases, patients undergoing a surgical resection of a tumor of the head, neck, or spine are referred for a procedure to reduce blood supply to the tumor.
Stenosis at the origin of the vertebral artery is a recognized risk factor for ischemic stroke. Patients who have symptoms of stroke or transient ischemic attack (TIA) may undergo diagnostic imaging to evaluate the blood vessels of the head and neck.
Vertebral body compression fractures can be identified on plain x-ray or CT imaging and appears as collapse of the vertebral body. A minimally invasive treatment is vertebral body augmentation with kyphoplasty or vertebroplasty.
A Wada test is used for pre-operative surgical planning in epilepsy. Patients who have epilepsy that is refractory to medications, and who are selected as candidates for surgical resection of a region of abnormal brain tissue, may undergo a Wada test.
