Your specialists for congenital vascular malformations

For more than 40 years I have been working as a vascular surgeon and treating congenital vascular malformations, especially in children, and I know the distress this can cause to patients and their families. People from all over the world travel to visit me at the Facharztklinik Hamburg [Hamburg Specialist Medical Clinic], as they have not been able to find help elsewhere. In cooperation with me, Dr. C. Gebhardt (specialist for vascular surgery) is avaible for you. By as early as the initial examination, we can offer encouragement to the majority of those affected, as congenital vascular malformations can almost always at least be positively influenced during the course of treatment, or even significantly improved. 

As co-founder and former president of ISSVA (International Society for the Study of Vascular Anomalies) I am constantly exchanging interdisziplinary experiences with my specialized colleagues worldwide.


Congenital vascular malformations can be detected relatively quickly by a specialist, by means of a simple clinical examination. However, because general practitioners frequently fail to detect the symptoms, incorrect diagnosis is unfortunately a frequent occurrence.



About the doctor

Prof. Loose is one of the rather few specialised doctors in the world today that focus in detail on congenital vascular malformation. He has treated more than 3,200 patients suffering from this condition and has successfully performed more than 6,000 operations.



Hardly any other vascular disease has such a varied clinical presentation as congenital vascular malformation. The disease manifests itself in the form of a pathologically altered vascular layout and circulatory system, which in most cases causes continual growth.



Prof. Loose has published numerous books on the topic of congenital vascular malformation, in a variety of languages. In addition to these, he has been published in specialist medical publications and has also given lectures at various conferences and symposia.
