William Tony Parks
MD
Dr W. Tony Parks received his medical degree from Washington University School of Medicine in St. Louis.
After completing a residency in Anatomic Pathology at the University of Colorado, he undertook a research fellowship at the National Cancer Institute in Bethesda, MD, studying the biochemistry of the TGF-beta signaling pathway.
His clinical subspecialty is perinatal pathology, with a particular interest in the placenta.
He has been the Director of Perinatal Pathology at Magee-Women’s Hospital, Dartmouth-Hitchcock Medical Center and Northwestern University Medical Center.
Research Synopsis
While my research interests include trophoblast biology and the pathology of stillbirth and preterm birth, my recent work has centered around the topic of placental maternal vascular malperfusion.
The lesions of maternal vascular malperfusion develop in the context of decreased or altered blood flow from the mother to the placenta.
Some (such as decidual arteriopathy) are likely etiologic, while others (such as increased syncytial knots and accelerated villous maturation) are likely secondary responses to placental hypoxia or hypoxia/reperfusion injury.
Current studies suggest that, like preeclampsia and other clinical adverse pregnancy outcomes, evidence of maternal vascular malperfusion in a placenta may independently increase a woman’s risk for later life cardiovascular disease.
As part of these studies, I also have a keen interest in systematizing and developing a more rigorously scientific grounding for both the diagnosis of these lesions and the assessment of their impact on the mother and her child.
