Venous Malformations are abnrmal structures arising from the veins present since birth. They usually grow in proportion to a child’s growth but venous malformations never regress. Venous malformations lesions do not go away unless treated.

The individual lesions may appear as soft, bluish colour small lumps or may be hidden and appear as a colour-less lump. The very deep lesions inside the muscles or the joints are not visible to the naked eye. Such malformations may present with pain over the affected area.

Venous malformations are easily compressible but may become hard in certain areas due to repeated clotting.

The so-called 'trunclar' venous malforemations arise from the trunks of major veins and such patients can present with what might appear as advanced varicose veins.

Venous malformations are investigated by duplex ultrasound and MRI. Ultrasound is helpful in making the diagnosis and to determine the type of the malformation. MRI is useful in determining the extent.

Venous malformations are treated at Sydney Skin and Vein Clinic by endovenous laser ablation (EVLA) for larger lesions and foam Ultrasound Guided Sclerotherapy for smaller ones. EVLA in particular is very successful in providing long term relief.
