[The embolisation of venous malformations].

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Malformations

Background:

• Congenital vascular malformations, specifically venous malformations (VMs), present significant therapeutic challenges.
• Existing treatment options require further definition regarding their individual efficacy.
• A retrospective study analyzed 61 patients with VMs, focusing on clinical manifestations and treatment outcomes.

Purpose of the Study:

• To evaluate the effectiveness of embolization techniques in treating venous malformations.
• To assess the clinical relevance and outcomes of different embolization methods.
• To determine the complication rates associated with embolization procedures for VMs.

Main Methods:

• Retrospective analysis of 61 patients diagnosed with venous malformations over five years.
• Pre-treatment assessment included MR angiography with venous sequences.
• Treatment involved various embolization techniques, including foam sclerotherapy, glue injection, pelvic vein coiling, and arterial embolization.

Main Results:

• 69% of patients underwent procedures due to symptoms or VM extension.
• Foam sclerotherapy was the most frequent technique (45 interventions).
• Significant improvement was reported by 92% of patients (60% very good, 32% marked), with minimal complications like pain and skin necrosis.

Conclusions:

• Embolization is a highly effective therapeutic strategy for venous malformations.
• Tailored embolization techniques can address diverse VM localizations and patterns.
• A step-by-step approach ensures a low complication rate, facilitating repeat interventions and improving patient outcomes.
