OBJECTIVE: To report results of the application of endovascular techniques in the management of scalp cirsoid aneurysms. MATERIALS AND METHODS: Four patients diagnosed with cirsoid aneurysms were submitted to treatment by endovascular approach. All the four patients included in the present series had arteriovenous malformations and were treated solely by embolization. RESULTS: Three of the patients underwent endovascular treatment by transarterial embolization and one was treated by direct puncture of the venous segment. Both clinical and cosmetic outcomes were satisfactory in all of the patients. Clinical relapse was not observed along the follow-up period. CONCLUSION: The endovascular approach is safe and effective in the management of crisoid aneurysms. Although this technique can be used as an adjuvant or complement to surgery, particularly in cases where deep afferents are involved, complete resolution can be achieved only with endovascular treatment. The choice of treatment method should be based on a range of typical characteristics of the lesion, including angioarchitecture, size and clinical presentation.
