A 68-year-old man presented with headache and generalized tonic-clonic seizures with rapid progression to refractory status epilepticus requiring temporary endotracheal intubation and deep sedation. He was admitted to our institution 5 days later from another hospital for further diagnosis and treatment. Cranial computed tomography (CT) scan and CT angiography revealed subarachnoid and intraventricular hemorrhage associated with a left temporal arteriovenous malformation (AVM) graded as Spetzler-Martin II. Digital subtraction angiography (DSA) confirmed a compact left temporal AVM nidus supplied by branches of the middle cerebral artery. Drainage was via a single inferior anastomotic vein of Labbé and a dangerous anastomosis to the vein of Trolard and the middle superficial Sylvian vein. The left posterior temporal artery, the main feeder of the AVM, was catheterized via a transfemoral arterial approach. The left vein of Labbé was accessed via a transfemoral venous approach. An antireflux plug was created in the vein of Labbé distal to the venous drainage of the AVM using coils and nHCA (Magic Glue, Balt) after coil protection of the anastomotic area between the superficial Sylvian vein and the vein of Labbé. Arterial and venous embolization was then performed simultaneously with Onyx injection until complete obliteration of the nidus was observed. The main topic of this chapter is the combined transvenous and transarterial embolization of a cerebral AVM using the pressure cooker technique.
