We report a case of tentorial dural arteriovenous fistula (DAVF) with a severe intracranial hemorrhage occurring after Onyx embolization. A 40-year-old man presented with an asymptomatic tentorial DAVF on angiography. Transarterial embolization with Onyx was performed via the middle meningeal artery, and the cast filled the fistula itself and its proximal draining vein. Postoperative angiography confirmed complete occlusion of the DAVF. A computed tomography scan performed immediately after the procedure demonstrated an acute subdural hematoma with the temporal hemorrhage...

Congenital arteriovenous malformations (AVMs) are an important but often neglected cause of lower extremity venous hypertension. A case of a chronic refractory venous stasis ulcer of the lower extremity exacerbated by a pelvic AVM is presented. Healing of the ulcer was achieved at 2 months without recurrence at 1 year after superselective ethylene vinyl alcohol copolymer (Onyx 34; ev3, Covidien, Plymouth, Minn) embolization of the AVM nidus. Chronic venous arterialization should be considered in cases of refractory, nonhealing venous ulcers...

Spinal extradural arteriovenous fistulas (SEDAVF) with intradural drainage are uncommon vascular lesions that cause venous congestive myelopathy. We present three SEDAVF with intradural drainage treated with surgical disconnection of the intradural drainage via a single level laminectomy, followed by transarterial embolization (TAE) with Onyx if spontaneous thrombosis of the extradural fistula did not occur spontaneously. All patients improved their neurological condition and no congestive myelopathy recurrence was noted after mean follow-up of 84 months...

Endovascular occlusion via the transvenous route is the favored treatment for indirect carotid-cavernous fistulas (CCFs). However, transarterial embolization can be used as an alternative method in patients with an inaccessible venous route. The authors present the case of a 49-year-old woman with a 2-month history of chemosis and proptosis in her right eye. Angiography demonstrated a Barrow Type D CCF. Transarterial Onyx embolization through the accessory meningeal artery was performed after an unsuccessful transvenous approach...

Oprozomib (OPZ or ONYX 0912) is an irreversible, orally administered proteasome inhibitor (PI) and an analog of carfilzomib. We set out to determine the anti-angiogenic effect of OPZ using the choriollantoic membrane/feather bud (CAM/FB) model and its anti-MM effects using MM xenograft models (LAGκ-1A, LAGλ-1). OPZ significantly reduced blood vessel formation, endothelial gene and protein expression using the CAM/FB assay. In vivo, we determined the anti-MM effects of OPZ, dexamethasone (Dex) and pomalidomide (Pom) and showed that the combinations of two drugs (OPZ+Dex or OPZ+Pom) showed marked anti-MM effects when compared to monotherapy...

OBJECTIVE: Endovascular aortic aneurysm repair has become the principle technique used to treat abdominal aortic aneurysms. However, its long-term success is limited by complications, including type II endoleaks from lumbar arteries and the inferior mesenteric artery. Treatment of these endoleaks can be difficult. The most commonly performed procedure is embolisation via mesenteric or iliolumbar vessels. Embolic agents currently used include coils, glue and Onyx, all of which have their limitations...
