Background: Vascular anomalies or vascular birthmarks can be divided in to 2 major groups: (i) vascular tumors and (ii)
vascular malformations. Currently, there are many treatment modalities for these diseases and the treatment plans are varied
among sub-specialty physicians.
Objective: To explore the epidemiology of vascular anomalies at Srinagrind Hospital during 2009-2011.
Material and Method: Retrospective chart was reviewed from the out patient clinic’s database at Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand.
Results: There were total of 126 vascular anomalies cases. 89 cases were diagnosed with vascular tumors and 37 cases were
vascular malformations. Among 89 cases of vascular tumors, infantile hemangiomas are the most common type (95.5%).
The treatment methods for vascular tumors were medical treatments, which were used in majority of the cases (60%),
followed by surgical excision, laser treatment, intralesional corticosteroids injection, and the combination of medical, laser
and surgical treatment. There were total of 37 cases of vascular malformations. Most of the cases were venous and lymphatic
malformations. Treatment methods for these patients were surgical excision, bleomycin injection, and radiation.
Conclusion: Vascular anomalies have various presentations. Treatment is challenging and multidisciplinary teams are
involved in taking care the patients with this entity of disease. Setting up vascular anomalies clinic is essential and suggested
for the patients with vascular anomalies’ problems.
