<jats:sec><jats:title>Background</jats:title><jats:p> Scalp arteriovenous malformations (AVMs), or cirsoid aneurysms of the scalp, usually present with troublesome symptoms and cosmetic disfigurement. Endovascular/percutaneous embolization has evolved as a sole treatment method or adjunct to surgical excision in the management of scalp AVMs with an excellent outcome. </jats:p></jats:sec><jats:sec><jats:title>Purpose</jats:title><jats:p> To discuss minimally invasive techniques for treating scalp AVMs as well as to highlight the role of embolization before surgery. </jats:p></jats:sec><jats:sec><jats:title>Material and Methods</jats:title><jats:p> This is a retrospective study of 50 patients with scalp AVM who underwent embolization (percutaneous/endovascular) during 2010–2019 at a tertiary care center. n-butyl cyanoacrylate (n-BCA) was used as an embolizing agent in all the cases and the patients were followed up at three- and six-month intervals with Doppler evaluation. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> A total of 50 patients were included in the study. The occipital region was the most common location; 82% were Schobinger class II lesions and 18% were class III lesions. Thirteen patients had small-sized AVMs and 37 patients had large-sized AVMs. Post-embolization surgery was performed in 36 patients. Of the patients, 28 underwent percutaneous embolization, 20 underwent endovascular embolization, and two underwent both to achieve complete embolization of the lesion. The number of percutaneous procedures increased in the latter half of the study period as the safety and efficacy of the technique were established. No major complications were seen in this study. </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> Embolization of scalp AVMs is a safe and effective technique and can be used in isolation for small lesions and as an adjunct procedure to surgery for large-sized lesions. </jats:p></jats:sec>
