Molecular changes associated with vascular malformations

Area of Science:

• Vascular biology and genetics
• Molecular mechanisms of disease
• Medical and surgical treatment of vascular anomalies

Background:

• Vascular anomalies are broadly categorized into tumors and malformations.
• Somatic mosaic gene mutations are the primary cause of most vascular malformations.
• Genetic research has elucidated key biomolecular pathways in pathogenesis.

Purpose of the Study:

• To review the updated International Society for Study of Vascular Anomalies classification.
• To highlight potential therapeutic targets based on genetic findings.
• To provide vascular surgeons with an updated perspective on etiologies.

Main Methods:

• Literature review of current research on vascular anomalies.
• Analysis of genetic mutations and associated signaling pathways.
• Integration of updated classification systems.

Main Results:

• Vascular malformations are linked to specific genetic mutations.
• RAS/MAPK/ERK pathway mutations are associated with fast-flow arteriovenous malformations.
• PI3K/AKT/mTOR pathway mutations are associated with slow-flow venous and lymphatic malformations.

Conclusions:

• Understanding the genetic basis of vascular malformations informs targeted therapies.
• Therapeutic strategies should focus on the specific mutated etiological pathways.
• This knowledge facilitates multidisciplinary collaboration for improved patient care.
