Review Case Reports
Hypertensive posterior reversible encephalopathy syndrome causing posterior fossa edema and hydrocephalus.
Posterior reversible encephalopathy syndrome (PRES) is a well characterized entity resulting from the inability of cerebral autoregulation to adequately protect the brain from uncontrolled hypertension. It primarily affects the occipital lobes, but can also involve the structures in the posterior fossa including the brainstem and cerebellum. ⋯ In rare cases, PRES can present with severe brainstem compression requiring emergent posterior fossa decompression. When brainstem signs are present on exam, emergent posterior fossa decompression may be safer than ventriculostomy alone.

Stereotactic radiosurgery (SRS) is a well established, minimally invasive treatment option for patients diagnosed with cerebral arteriovenous malformations (AVM). We present the experience in linear accelerator-based SRS for cerebral AVM treated over 14 years. We prospectively followed 67 patients with 69 AVM treated with SRS from 1994 to 2008, inclusive. ⋯ Larger AVM diameter was associated with increased odds of requiring re-treatment (p=0.02). Radiosurgery for intracerebral AVM is a non-invasive therapeutic option with low morbidity and a reasonable likelihood of nidus obliteration. Treatment dose and AVM diameter are the main determinants of obliteration.

The SILK flow diverter (SFD; Balt Extrusion, Montmorency, France) is a flow diverting stent used in the endovascular treatment of intracranial aneurysms. It works on the principle of redirecting flow away from the aneurysm sac, leading to occlusion over time. We present a systematic review on the clinical outcomes and complications of the SFD. ⋯ The main outcome measure, 12 month AOR, was 81.8% with complete occlusion in 216 out of 264 aneurysms. Use of flow diverters for the treatment of intracranial aneurysm with complex morphologies has gained in popularity over the last few years. Our review suggests that SFD achieves comparable AOR to its contemporary, the Pipeline Embolization Device (ev3 Endovascular, Plymouth, MN, USA) but has a higher rate of higher rate of ischemic complications, aneurysm rupture and mortality.
