Vascular Anomalies: A 3-Year Review in the Paediatric Institute Hospital Kuala Lumpur Between 2013 And 2015

ABSTRACT

Introduction:Vascular anomalies, regardless of tumour or malformation, may result in significant morbidity. Thediagnosis of vascular anomalies in the paediatric group is always challenging. We aim to describe thepattern of vascular anomalies referred to the Paediatric Institute Kuala Lumpur Hospital (PIKLH).Methods:This is a 3-year retrospective review on vascular anomalies among children referred to PIKLH between2013 and 2015.Results:There were 289 children; male to female ratio of 12.1; aged from birth to 14 years with median age of5 months recruited. The referring diagnoses included haemangioma (71.3%), capillary malformation(13.8%), lymphatic malformation (1.7%), kaposiform hemangioendothelioma (1.0%) and others. Ahundred and sixty-one (55.7%) had lesions located at the head and neck region, followed by trunk(14.2%), lower limbs (9.3%), upper limbs (7.6%), perineum (3.8%) and multiple sites (6.9%). In 197patients (68.2%), there were no further investigations performed, 13.5% had ultrasonography, 7.3%had MRI, 4.8% had both ultrasonography and MRI; 4.1% had skin biopsy, 0.3% had angiogram.The final diagnoses were haemangioma (72.3%) of which 10 were ulcerated; capillary malformations(17.6%), combined vascular malformations (2.4%), kaposiform hemangioendothelioma (2.8%),lymphatic malformations (2.1%); venous malformations (1.4%); tufted angioma (1.0%) andarteriovenous malformations (0.3%). One hundred and nine patients (37.7%) received beta-blockers;71(24.6%) underwent laser, 16(5.5%) received sirolimus, 9(3.1%) received systemic corticosteroidswith vincristine, 4(1.4%) had systemic corticosteroids, 3(1.0%) had excision and 2(0.7%) hadsclerotherapy. The remaining patients were put under observation.Conclusion:Three-quarters of the vascular anomalies referred were hemangioma followed by vascularmalformations. Vascular anomalies have a large variation in clinical presentation. Expertise inthe diagnosis and management modalities are essential to achieve optimum outcomes. Thereforevascular anomalies are best managed in a multidisciplinary setting.
