The Vascular Lesion Program provides a comprehensive treatment approach to complex vascular lesions, including pediatric brain aneurysms, cerebral cavernous malformations and arteriovenous malformations.
Aneurysms refer to a weakness in an artery causing a protruding, bulging bubble-like or pouch-like abnormality involving vascular complexities. The reason can be genetic, induced as a result of other primary abnormalities, infectious, or idiopathic (with unknown cause) in nature. Most aneurysms in the brain appear in the space between the brain and its surrounding tissue, known as the subarachnoid space, and can cause a subarachnoid hemorrhage when they rupture. A subarachnoid hemorrhage is a medical emergency and may lead to permanent brain damage or death if not treated promptly.
Arteriovenous malformations are a tangle of abnormal blood vessels (arteries and veins) and occur most commonly in the brain. In patients with an AVM, blood flowing at high pressure through the arteries pumps directly into the veins rather than passing (as it should) through a bed of tiny vessels (capillaries), which nourish the brain tissue and reduces the pressure of the blood entering the veins. Eventually, the consistently high-pressure blood flow through the AVM can cause the vessels to expand, potentially resulting in a rupture and associated bleed.
The Rady Children’s Pediatric Cerebrovascular Program is the largest in the United States. Pediatric vascular lesions are treated by a highly skilled and multidisciplinary team, including renowned specialists in neurosurgery, plastic and craniofacial surgery, diagnostic imaging and interventional radiology, laser surgery, genetics, orthopedics, otolaryngology, ophthalmology and dermatology.
Intracranial and intraspinal lesions are treated by a combination of interventional, surgical and stereotactic radiosurgical approaches.
