Evaluation and Treatment of Patients Spinal Blood Vessel Abnormalities
Arteriovenous malformations (AVM) are abnormally formed blood vessels that can be located throughout the brain and spinal cord. Patients with abnormalities of the blood vessels located in and around the spinal cord can develop many neurological problems. Some problems include, weakness, pain, difficulty walking, paralysis, and even death.
The treatment for these AVMs depends on their location, the type of malformation, the area of the spine involved, and the condition of the patient at the time of treatment. The treatment is aimed at stopping the neurologic problems from worsening and possibly correcting the existing problems. There are two commonly used treatments for AVMs, surgery and embolization (blocking off of blood flow to the AVM).
However, researchers have limited experience treating these conditions because they are rare. In addition, it has been difficult to classify different kinds of AVMs and to develop new treatments for them.
This study is designed to increase researchers understanding of AVMs by admitting and following patients diagnosed with the condition. By increasing the amount of patients studied diagnosed with spinal blood vessel abnormalities, researchers can begin to develop new management plans for patients with AVMs.
