Magnitude and relevance of change in health-related quality of life in patients with vascular malformations treated with sirolimus.

Introduction: Vascular malformations are rare congenital anomalies of the vascular system, which can involve the capillaries, veins, arteries, lymphatics, or a combination of vessel types. Patients with vascular malformations experience an impaired health-related quality of life (HRQoL) because of their symptoms (e.g.

Clinical differences in sirolimus treatment with low target levels between children and adults with vascular malformations - A nationwide trial.

The clinical presentation of patients with slow-flow vascular malformations is very heterogeneous. High clinical burden and subsequent reduced health-related quality of life is something they have in common. There is an unmet medical need for these patients for whom regular treatments like surgery and embolization are either insufficient or technically impossible.
