Vein of Galen Malformation

Vein of GalenPost Op

The patient is a 4-month-old boy from Haiti with a history of low weight gain, cachexia, congestive heart failure and pulmonary hypertension, but with no discernable cause. After first presenting to a hospital in Haiti, he was treated with oxygen concentrators and sildenafil to maintain his oxygen saturation levels, but could not gain weight.

After two months, the patient was seen by a cardiologist in Haiti, who identified a vein of Galen malformation by cranial ultrasound. This rare arteriovenous malformation is characterized by the presence of large, dilated blood vessels with abnormally high flow within the brain, sapping blood supply from the rest of the body and increasing stress on the heart, causing high-output congestive heart failure.

At age 10 months, the patient was transported from Haiti to Boston, where his care required a multidisciplinary team including cardiology, cardiac anesthesia, interventional neuroradiology and feeding and nutrition. After cardiologists stabilized his heart, an interventional neuroradiologist conducted two rounds of embolization to close off most of the flow through the malformation. Within two weeks after the second embolization, the patient was moved out of intensive care and weaned off of supplemental oxygen shortly thereafter. He began to eat solid food and quickly gained appropriate weight. 

The future of pediatrics will be forged by thinking differently, breaking paradigms and joining together in a shared vision of tackling the toughest challenges before us.”
