Venous vascular malformations of the craniofacial region: pre-operative embolisation with direct percutaneous puncture and N-butyl cyanoacrylate.
Craniofacial venous vascular malformations cause severe cosmetic problems and yet these lesions are not candidates for transcatheter embolisation owing to the lack of arterial feeders. The purpose of this study was to evaluate the effectiveness of pre-operative embolisation of these lesions with N-butyl 2-cyanoacrylate (NBCA) via direct puncture. Between September 2003 and April 2006, 13 patients (7 female; age range, 6-64 years; mean, 16.7 years) were embolised with direct puncture and injection of NBCA. All of the patients were referred from plastic surgery with an operational plan. Angiography performed in all patients showed no or little arterial staining. NBCA diluted with iodized oil at a ratio of 1:6 (18%) was injected via a percutaneously placed 21 gauge needle. Complete embolisation was achieved in 8 patients and partial embolisation in the remaining 5. A total of 18 sessions of embolisation were performed on 13 patients. Nine patients underwent only one embolisation session, three patients underwent two sessions and only one patient underwent three sessions. The mean volume of NBCA used per session was 5.8 ml, ranging from 1-12 ml. All patients underwent a successful surgical resection to improve cosmetic disfigurement within 10-15 days after the embolisation procedure. Mean follow-up time was 22 months. One patient experienced skin necrosis on her nose after embolisation. No other complications related to the procedure were observed. In conclusion, pre-operative NBCA embolisation with direct puncture is a safe and easy procedure. It can increase the success of the surgical treatment of these lesions.
