    Study Notes

    CO2 Laser

    • CO2 lasers have a high affinity for water
    • CO2 Lasers are used for soft tissue removal and hemostasis
    • CO2 lasers have a biostimulation effect that assists with wound healing and hemostasis

    Ultrasound

    • Ultrasound and Doppler analysis can be used to determine if vascular abnormalities are solid or cystic
    • Ultrasound and Doppler analysis can determine the presence or absence of high-flow vessels

    Venous Malformations

    • Direct intralesional injection of contrast medium can be useful in analyzing venous malformations
    • Preoperative histological confirmation might not be necessary for vascular lesions, as features are characteristic and help differentiate between various vascular lesions

    Low-Flow Malformations

    • Low-flow malformations are made up of postcapillary venules located within the papillary and superficial reticular dermis

    Capillary Malformations

    • Capillary malformations are also known as venular malformations
    • The primary treatment method for capillary malformations is laser application
    • Pulsed dye lasers are the preferred treatment for capillary malformations
