The center has reduced the number of patients having major strokes during bypass surgery to 1%, and less severe injury to 18%, significantly below national averages. The research aims to make a safe operation even safer by exploring additional ways to avoid brain injury.
Researchers at Cedars-Sinai Medical Center have developed a groundbreaking brain cell transplantation technique aimed at treating neurodegenerative diseases such as Parkinson's disease, stroke, and epilepsy. By selectively growing and implanting targeted brain cells, the team hopes to promote healing and repair damaged brain tissue.
Neurosurgeons successfully tested a new magnetic surgery system on the world's first human patient, allowing for precise navigation of surgical tools through the brain. The innovative technology has far-reaching potential for various applications, including implanting electrodes, repairing aneurysms, and delivering targeted treatments.
A new international study has identified that small intracranial aneurysms have a very low probability of rupture if the patient has no history of ruptured aneurysms. Patients with these conditions can live a normal lifestyle with minimal risk while monitoring their aneurysm.
Researchers at UB's Toshiba Stroke Research Center have developed a new dual contrast injection method, enabling neurosurgeons to characterize and treat arteriovenous malformations (AVMs) more effectively. The technique allows for precise measurement of blood flow rate, facilitating the accurate administration of a glue-like substance ...
Researchers at Thomas Jefferson University have developed a method to reverse dangerous cerebral vasospasms. The treatment involves administering a drug that dilates cerebral blood vessels, reversing constricting effects within 30 minutes.
Dr. David Stump's research reveals a significant impact on patients' lives, with long-term effects on motor skills, hand-eye coordination, and daily functioning. The study highlights the importance of early detection and addressing post-operative deficits to prevent decline in brain function.
Researchers have made significant strides in reducing post-surgical brain deficits by modifying surgical technique and using ultrasound monitors to detect emboli. The team has cut the number of patients experiencing confusion, memory loss, and personality changes after coronary artery bypass surgery.
Researchers have found that a left-handed woman's brain controls reading aloud and speaking with the left side, but writing with the right. This study compares split-brain cases to V.J.'s and suggests that spoken and written language evolved independently.
A study at the University of Toronto has discovered a biological basis for phantom sensations experienced by amputees. The researchers found that neurons in the brain that used to represent sensation in the lost limb remain functional and are now driven by stimulation of other body parts, usually the part closest to the amputated limb.
Researchers at Thomas Jefferson University have developed a non-invasive gamma knife treatment that shows comparable results to surgery in alleviating Parkinson's disease symptoms. The treatment uses high doses of radiation to destroy targeted areas of the brain, potentially offering an alternative to traditional surgical options.
Researchers have discovered a promising approach to protecting the brain from damage during heart bypass surgery, using chemicals that inhibit nitric oxide production and reduce glutamate accumulation. Patient trials are expected to start in early 1998.
A study of 65 patients found that those with the Alzheimer's-related gene apoliprotein E-4 (APOE-4) are more susceptible to mental impairment after open heart surgery. The researchers believe this is due to the variant gene's inability to repair nerve cells efficiently.
A new study reveals that transcranial sonography is more sensitive than MRI and CT in detecting residual tumors and predicting patient survival after brain tumor surgery. This non-invasive imaging technique offers advantages, including lower cost, portability, and ease of use, making it a valuable tool for follow-up care.
Pediatric heart surgeons are using ultrasound to monitor patients for potential brain damage during and after open-heart surgery. The non-invasive method, Transcranial Doppler, can detect air in the brain circulation when it is ejected from the heart, providing valuable feedback for surgeons.
A study published in the Journal of Neurosurgery found a significant link between smoking and cerebral blood-vessel damage. Smokers are nearly five times more likely to develop vasospasm, a violent constriction of arterial walls that can lead to stroke-like symptoms.
A Duke neurologist advocates for mandatory reporting of complication rates for carotid endarterectomy to help doctors make informed decisions. Low complication rates are crucial for the procedure's effectiveness in preventing strokes.
A new study suggests that a drug that inhibits nitric oxide production may reduce the risk of brain damage during heart surgery. The study found that dogs treated with the drug showed significantly less apoptotic brain cell damage and decreased nitric oxide in the brain compared to untreated dogs.
Researchers found that a drug called MK-801 can reduce brain cell death during cardiac surgery by blocking glutamate receptors. The study used dogs and showed promising results, suggesting a potential new approach to preventing brain damage during heart surgery.
The new resorbable plates and screws dissolve within months of implantation, reducing migration and discomfort in young patients. Developed by Biomet Corporation, these devices have been approved by the FDA for use in reconstructive head and neck surgery.
