SUMMARY Arteriovenous malformations (AVMs) of the scalp are rare lesions. The clinical picture presents with complaints of increased scalp, scalp disfigurement, pain and neurological symptoms. Its origin can be congenital or traumatic. We present a case of giant scalp AVMs and its management, followed by a brief literature review on the subject. The diagnosis of scalp AVMs is based on physical examination and confirmed by internal and external carotid angiography or computed tomographic angiography (CTA). Surgical excision is especially effective in scalp AVMs, and is the most frequently used treatment modality.

Abstract OBJECTIVE We introduce a technique that enables the use of catheter angiography during image-guided surgery for the resection of previously embolized arteriovenous malformations. METHODS We used models to test the possibility of matching specific anatomic points 1:1 and the accuracy of merging catheter-based 3-dimensional angiography with standard computed tomographic angiography. RESULTS After obtaining excellent accuracy matching the 2 modalities, we merged both studies into the image-guidance platform. After embolizing a patient's arteriovenous malformation with Onyx, we successfully used the merged study to navigate during surgical resection of the lesion. No complications resulted from this technique, which increases contrast by only 15 cm3 and radiation exposure by 4 seconds. CONCLUSION Catheter-based angiography can be used during image guidance to reduce the artifact from metal particles after embolization. Excellent accuracy was obtained in merging 3-dimensional angiography with computed tomographic angiography. Further studies are needed to evaluate catheter-based 3-dimensional angiography as a single method for navigation during neurovascular surgery.
