Abstract. Background: The technical and clinical outcomes of catheter-directed embolization for peripheral arteriovenous malformations (AVM) using Onyx® (ethylene-vinyl alcohol copolymer) are not well documented. The purpose of this study was to retrospectively assess the safety, technical outcomes and clinical outcomes of catheter-directed Onyx® embolisation for the treatment of symptomatic peripheral AVMs. Patients and methods: Demographics, (pre-)interventional clinical and radiological data were assessed. Follow-up was based on hospital medical records and telephone calls to the patients’ general practitioners. Radiological success was defined as complete angiographic eradication of the peripheral AVM nidus. Clinical success was defined as major clinical improvement or complete disappearance of the initial symptoms. Results: 25 procedures were performed in 22 patients. The principal indications for treatment were pain (n = 10), limb swelling (n = 6), recurrent bleeding (n = 2), tinnitus (n = 3), and exertional dyspnoea (n = 1). Complete radiological success was obtained in eight patients (36 %); near-complete eradication of the nidus was achieved in the remaining 14 patients. Adjunctive embolic agents were used in nine patients (41 %). Clinical success was observed in 18 patients (82%). Major complications were reported in two patients (9 %). During follow-up, seven patients (32 %) presented with symptom recurrence, which required additional therapy in three patients. Conclusions: Catheter-directed embolisation of peripheral AVMs with Onyx® resulted in major clinical improvement or complete disappearance of symptoms in the vast majority of patients, although complete angiographic exclusion of the AVMs occurred in only a minority of patients.

Radiation therapy (RT) plays an important role in treatment of primary and metastatic CNS tumors and some non-neopiastic conditions (arteriovenous malformations, trigeminal neuralgia). Radiation necrosis (RN) is a common adverse effect of RT. Until recently steroid therapy was used as a main treatment regimen for RN. Mechanisms of RN development are not clear; however, it was shown that vascular endothelial growth factor (VEGF) plays a critical role in its formation. A number of surveys showed efficacy of bevacizumab as an anti-VEGF agent in treatment of RN. Radiation necrosis pathogenesis, diagnostics and treatment are summarized in this review.
