Surgical management of scalp arterio-venous malformation and scalp venous malformation: An experience of eleven cases

Abstract

Aims: Scalp arterio-venous malformation (AVM) and scalp venous malformation (SVM) are rare conditions that usually need surgical treatment. Here, we have reported our experience of the surgical management of such lesions with a short review of the literature. Materials and Methods: In this prospective study, 11 patients with scalp AVM and SVM, who underwent surgical excision of lesion in our hospital from 2006 to 2012, were included. All suspected high-flow AVM were investigated with the selective internal and external carotid digital subtraction angiogram (DSA) ± computed tomography (CT) scan of brain with CT angiogram or magnetic resonance imaging (MRI) of brain with MR angiogram, and all suspected low-flow vascular malformation (VM) was investigated with MRI of brain + MR angiogram. Eight were high-flow and three were low-flow VM. Results: All lesions were successfully excised. Scalp cosmetic aspects were acceptable in all cases. There was no major post-operative complication or recurrence till last follow-up. Conclusions: With preoperative appropriate surgical planning, scalp AVM and SVM can be excised without major complication.
