Active clinical trials for "Osteolysis, Essential"

Lymphatic anomalies are a rare subset of vascular anomalies that are poorly understood. the understanding of the natural history, long-term outcomes, risk factors for morbidity and mortality, and the relative benefit of medical therapies and procedures is limited.The goal of this project is to better understand these diseases and improve the care of theses rare patients. To do this, the investigators are conducting an observational study of patients with lymphatic anomalies, including an annual follow-up questionnaire to gather prospective data on mortality, morbidity, treatments, and functionality as well as quality of life.

The study will use blood (serum and plasma) and tissue obtained from participants undergoing prescribed surgical resection of vascular anomalies of interest proposed in this study. The study will also use blood (serum and plasma) and tissue collected and stored in a tissue bank maintained by the Department of Hematology/Oncology.

Lymphatic Anomalies (LA) is characterized by proliferation of lymphatic tissue causing deterioration of pulmonary function. Understanding changes in lymphatic anatomy in these patients is hindered by the difficulty of imaging the lymphatic system. Dynamic Contrast Enhanced MR Lymphangiogram (DCMRL) may be useful in investigating pathological changes in the lymphatic system.
