Surgical management of scalp arteriovenous malformations using a novel surgical technique—Case series

Abstract

HighlightsTotal surgical excision is the only modality which guarantees a cure.Surgical excision is challenging due to troublesome intraoperative bleeding.Novel technique of temporary proximal feeding artery control and clipping prior to nidus excision.Results in decreased intra operative blood loss and operative time.Good outcome.

Excision of Large Scalp Arteriovenous Malformations with Aesthetic Scalp Reconstruction

“… 1 They can be present in all scalp regions with temporo-parietal being the commonest, as also evident in our study. 3 Main source of feeders is from superficial temporal and occipital artery. Persistence of embryonal capillary network in later stages of gestation leads to formation of intercommunicating channel, which results in formation of SAVMs.…”

“…DSA can be used to differentiate other vascular lesions like aneurysms and sinus perircanii. 3 MR angiography helps estimation of the form and extent of the lesion and also any intracranial extension. MR angiography helps planning the incisions before surgery, so that uninvolved major scalp vessels could be preserved.…”

“…The skin flaps are planned around these vessels for placement of expander and subsequent reconstruction of hair bearing scalp. 3 …”

“…Moreover, recurrence of lesion may occur few months down the line, if entire nidus is not excised. 3 …”
