Vascular malformations: a review of 10 years' management in a university hospital.

In order to gain insight into the management of patients with vascular malformations (VM) in the University Hospital Nijmegen in the past 10 years, 151 cases managed by different specialists were reviewed. To avoid the usual confusion in terminology, all recorded diagnoses were reclassified according to the biological classification of Mulliken. The sex distribution was equal; 79% of the malformations were diagnosed at birth or in the 1st year of life. The median time between presentation and consultation was 3 years. Sixty-two lymphatic, 26 venous, 24 capillary, 1 arterial, and 38 combined malformations (8 arteriovenous, 30 others) were found. The head and neck region was most frequently involved, followed by the lower and upper limbs and trunk. The pediatric surgeon was the most frequently consulted specialist. Confusing, mutually incompatible terminology and a wide variety of different diagnostic techniques and treatments had been used by the different specialists. To improve the management of patients with vascular malformations, the use of a uniform classification, an increase in basic investigations, and the development and evaluation of protocols for diagnosis and treatment by multidisciplinary teams are necessary.
