Vascular Malformations


About Vascular Malformations

Vascular malformations and angiomas include a variety of non-cancerous birthmarks. They are blood vessels anomalies that can involve arteries, veins, capillaries, lymphatics.

Hemangiomas are the most common type of vascular abnormality.

They usually appear during the first two weeks after birth and have a rapid growth, but after infancy they regress.

Most of hemangiomas don’t need treatment and go away usually by 5 to 7 years old.

Unlike hemangiomas, vascular malformations don’t regress but continue to grow throughout life.

There are different types of vascular anomalies and malformation and they are usually named according to the affected blood vessel (venous, arterial or both)

These may include:

  • Capillary vascular malformations (Port-Wine Stains)
  • Venous malformations
  • Arteriovenous malformations
  • Lymphangiomas
  • Angiofibromas
  • Pigmented lesions
  • Klippel-Trenaunay-Weber Syndrome

Vascular malformations impact on different parts of the body so they need to be treated with a multidisciplinary approach.

When they involve the musculoskeletal system they can cause problems that must be treated by an orthopedic surgeon, such as:


Prof. Portinaro and Vascular Malformations

Professor Portinaro is one of the most expert orthopedic surgeons to treat problems associated with vascular problems.

Main orthopedic treatments he performs are the removal of big intramuscular masses or to correct Leg Length Discrepancy.

On 27 – 29 September 2018 Prof. Portinaro took part as a Special Guest Lecturer in the SISAV International Congress on Vascular Malformations with a speech about Leg Length Discrepancy (LLD) correction in patients with vascular malformations.
