Vascular Anomaly Pathology and Genomics Biopsy Study

Vascular anomalies or vascular malformations often are treated with minimally invasive sclerotherapy, embolization or ablation based on clinical and imaging features without acquisition of tissue. Over the last two decades there have been significant advancements in the understanding of the genetic basis for various vascular anomalies/malformations, which may guide use of therapies for individualized treatment.

As such, given the emergence of novel medications for treatment of vascular anomalies/malformations based on genetic information, acquisition of tissue for pathology and genomic characterization will be increasingly important as treatment of vascular anomalies/vascular malformations moves toward individualized medicine approach.

Inclusion criteria

• Capacity and willingness to provide a written informed consent..

Exclusion criteria

• Subjects with prior treatment for their vascular anomaly.
• Uncorrectable coagulopathy.
