[Sonographically guided intralesional sclerotherapy for venous malformation]

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Dermatology

Background:

• Peripheral venous malformations are congenital vascular anomalies.
• Treatment options for venous malformations can be invasive and carry risks.
• Sonographically guided percutaneous intralesional sclerotherapy offers a less invasive alternative.

Purpose of the Study:

• To evaluate the safety and efficacy of sonographically guided percutaneous intralesional sclerotherapy for peripheral venous malformations.
• To assess the treatment outcomes and complication rates associated with this procedure.

Main Methods:

• 32 patients with soft tissue venous malformations were treated between March 2004 and October 2007.
• Intralesional sclerotherapy was performed using absolute alcohol and/or bleomycin under real-time ultrasound guidance.
• Treatments were repeated as needed, with follow-up ranging from 6 months to 2 years.

Main Results:

• A complete response was achieved in 27 patients (84.4%), with 5 patients (15.6%) achieving a partial response.
• Patients received an average of 3 treatment sessions.
• No major complications were reported during the study period.

Conclusions:

• Sonographically guided percutaneous intralesional sclerotherapy is a simple, effective, and safe treatment for peripheral venous malformations.
• The procedure is minimally invasive with a low morbidity rate.
• The therapy can be repeated to achieve optimal clinical outcomes.
