2. Methods
A retrospective chart review was performed at a single quaternary
institution. Patients with a diagnosis of intra-abdominal vascular
malformation treated at Cincinnati Children’s Hospital Medical Center
Hemangioma and Vascular Malformations Center between January 2000 and
December 2019 were included. Patients with an initial diagnosis of
non-solid organ intra-abdominal lymphatic malformation were included.
Isolated solid organ malformations such as those patients with
pancreatic, splenic, liver, or bowel were excluded for the purposes of
this study. Data was collected on demographics, presentation, treatment
and outcomes, and follow-up.
