Cerebrospinal fluid analysis is only necessary for patients with thunderclap headache and a negative computed tomography scan if they undergo imaging more than 6 hours after headache onset, research suggests.

Large study examines diagnostic yield of colonoscopy to investigate melena

A new study from researchers in Oregon reports that the diagnostic yield of colonoscopy to investigate melena after a nondiagnostic upper endoscopy is lower, 4.8 percent, than previously reported. The rate of therapeutic intervention in this population is very low; therefore, patients with melena and a nondiagnostic upper endoscopy who are stable and without evidence of ongoing bleeding may be able to safely undergo elective colonoscopy.

Bare platinum coils vs. newer gel-coated coils for aneurysm treatment

Approximately 6 million Americans have brain aneurysms, a condition that occurs when a weak or thin spot develops on a blood vessel in the brain causing it to balloon. Often, these do not cause symptoms and go undetected, but every year an estimated 30,000 Americans experience a ruptured aneurysm that bleeds into the brain causing a life threatening injury.

Gamma Knife stereotactic radiosurgery safe for treating children with arteriovenous malformations: Study

A new Mayo Clinic study has found that Gamma Knife™ stereotactic radiosurgery is a safe and effective option for selected children with arteriovenous malformations. This study was presented at the American Association of Neurological Surgeons Annual Meeting in Philadelphia last week.

Removing unruptured AVM decreases risk of hemorrhaging, provides better outcomes to patients

Individuals diagnosed with a brain arteriovenous malformation, an abnormal tangle of arteries and veins, are at an increased risk of vessel rupture and bleeding that can cause stroke and permanent brain damage.

UC San Diego Medical Center performs complex surgery on brain lesion

Over three decades, a world-recognized medical team at UC San Diego Medical Center has spurred the evolution of a complex surgery to destroy dangerous clusters of arteries and veins in the brain. Integrating innovative approaches in radiology, anesthesia, and surgery, the team has perfected a method to systematically starve these abnormal brain lesions, artery by artery, vein by vein.

Discovery of AVM can relieve pain due to chronic back pain and neurologic deficits

The discovery of a multi-level arteriovenous malformation (AVM) in the thoracic epidural space can now bring relief to potentially thousands of suffers of chronic thoracic pain and progressive myelopothy. Identified as thoracic epidural arteriovenous malformation (T.E.A.M.), this particular AMV primarily affects younger women ages 20 to 40.

Brain vessel malformations - intervention or a hands-off approach?

Individuals diagnosed with a brain arteriovenous malformation (BAVM) -- an abnormal tangle of arteries and veins -- are at increased risk of vessel rupture and bleeding that can cause permanent brain damage.

Women, Latinos face higher brain aneurysm risk

A type of stroke that can strike at any age, and kills one-third of its victims, appears to be more common in women and Mexican-Americans than in non-Hispanic white men, according to a new study from the University of Michigan Stroke Program.

Drug abuse linked to brain hemmorhage in young adults

A fifth of young adults whose blood vessels ruptured inside their brain abused drugs and more than 40 percent had malformed blood vessels, according to a study reported Feb. 17 at the American Stroke Association's International Stroke Conference 2006 in Kissimmee, FL.
