Blood Vessel Lesions
Pediatric Neurosurgeons and Neuro-Radiologists from Semmes-Murphy Clinicprovide expert surgical and angiography care at Le Bonheur Children’s Hospital for patients with conditions that involve blood vessel lesions, such as:
- Arteriovenous malformations: a tangle of abnormal blood vessels that is prone to bleed or irritate the brain. Symptoms of these lesions include seizures or small hemorrhages
- Cavernoma: a formation of fragile, dilated blood vessels that become tangled and form bubble-like structures called caverns. Often compared to the shape of a raspberry, they may go undetected until they bleed and become symptomatic
- Moyamoya disease: is unexplained narrowing of the cranial blood vessels. Often, this causes stroke or other symptoms of insufficient blood flow to the brain, such as seizures or weakness. The brain responds by developing very small collateral vessels that on radiographic images can appear to resemble a "puff of smoke," hence the Japanese name moyamoya, meaning puff of smoke
- Vascular lesions of the brain and spinal cord
- Vascular tumors
- Vein of Galen malformations
Our unique multidisciplinary program brings together specialists including pediatric neurosurgeons, neurologists, medical oncologists, neuroradiologists, interventional radiologists, geneticists and many others to provide the best comprehensive care for your child.
Usually children with moyamoya respond well to a low risk surgery called pial synangiosis. In this procedure, neurosurgeons place an artery directly on the brain surface to give the brain additional blood flow. This artery is then sewn to the brain and over time will develop collateral blood supply to the areas that are in need of additional blood.
