The Vascular Malformation Clinic brings together the expertise of multiple specialists with extensive experience in evaluating, managing and treating vascular malformations. Proper treatment for vascular malformations will depend on a concise diagnosis. Patients visiting the Vascular Malformation Clinic are evaluated thoroughly to ensure they receive the most appropriate treatment.

Physicians from the Department of Neurosurgery evaluate most vascular malformations of the central nervous system. Pulmonary malformations such as hereditary hemorrhagic telangiectasia (HHT) and Osler-Rendu-Weber disease are managed by physicians from Pulmonary Medicine. Congenital lymphedemas are managed by physicians in cardiology.


The Vascular Center in Arizona offers comprehensive and innovative diagnosis and treatment services for patients who have vascular malformations.
