Vascular Condition
Vascular Anomalies & Malformations
Vascular anomalies encompass a broad spectrum of conditions affecting blood vessels, including vascular malformations and vascular tumours such as haemangiomas. These conditions may be present from birth or appear in childhood and adulthood. Accurate diagnosis and multidisciplinary management are essential.
Symptoms
- Visible birthmark, skin discolouration, or soft tissue swelling
- Pulsatile mass with a bruit suggesting arteriovenous involvement
- Swelling or limb overgrowth in congenital malformations
- Pain, warmth, or skin changes over the lesion
- Bleeding, ulceration, or thrombosis within a malformation
- Heart failure in high-flow arteriovenous malformations
Causes & Risk Factors
- Congenital errors in vascular development (capillary, venous, lymphatic, or arteriovenous)
- Genetic syndromes associated with vascular anomalies (e.g. Klippel-Trenaunay, HHT)
- Haemangiomas — rapidly proliferating vascular tumours, typically of infancy
- Acquired arteriovenous fistulae from trauma or iatrogenic injury
Treatment
Treatment depends on the type, extent, and clinical impact of the anomaly. Options include observation, sclerotherapy, endovascular embolisation, laser treatment, surgical excision, or combination approaches. High-flow arteriovenous malformations are particularly complex and are best managed in a multidisciplinary setting.
Recovery & Aftercare
Recovery varies by treatment type and lesion complexity. Many patients require staged procedures over time. Long-term follow-up is often needed as vascular anomalies may recur or progress.
Frequently Asked Questions
Some vascular malformations can be cured with complete excision or targeted sclerotherapy. Others require long-term management rather than cure.
No. Haemangiomas are vascular tumours that grow rapidly in infancy and typically involute over years. Vascular malformations are structural abnormalities present from birth that do not involute.
When to Seek Medical Advice
- Rapidly growing birthmark or vascular lesion in a child
- Lesion causing pain, functional impairment, or cosmetic concern
- Pulsatile mass or lesion with a bruit
- Bleeding or ulceration from a known malformation
