Microsurgical clipping and endovascular flow diversion of ruptured anterior circulation blood blister-like aneurysms.
Conclusions Endovascular flow diversion is a viable option in the acute phase after SAH due to the rupture of a blister aneurysm. Implants with reduced thrombogenicity, obviating dual-platelet function inhibition, and flow diverters for vessel bifurcations would extend the indications for this treatment modality.

Mid-term 3T MRA follow-up of intracranial aneurysms treated with the Woven EndoBridge.
Conclusion WEB-treated aneurysms with adequate occlusion at three-month angiography remained stable during serial 3T MRA follow-up of 18-36 months. One PCA aneurysm reopened during the 6- to 18-month interval. Once the WEB-treated aneurysm is adequately occluded in the short term, later reopening is uncommon.

Recurrent periventricular hemorrhage in cerebral proliferative angiopathy: Case report.
We describe a case of CPA with multiple intra- and periventricular hemorrhages during 30-year follow-up. Recurrent bleeding in these areas are common in moyamoya disease. These lesions may share the cause of bleeding: proliferation of the periventricular vessels functioning as collateral pathways. Revascularization surgery for CPA may attenuate the vascular proliferation in the vicinity of the ventricle, which may prevent rebleeding.

Equine pericardium-covered stenting in post-traumatic pseudoaneurysm of cavernous internal carotid artery.
We report a case of traumatic intracranial carotid artery pseudoaneurysm treated with an equine pericardium-covered stent. The patient was admitted to the Emergency Department after sustaining severe polytrauma in a motor vehicle accident. A cavernous carotid pseudoaneurysm was detected after an episode of massive epistaxis that required emergent nasal packing. Treatment with parent vessel sacrifice was ruled out after an unfavourable balloon test occlusion. We opted for an equine pericardium-covered stent as a means to immediately seal the wall defect in the setting of massive bleeding secondary to an unstable lesion. We ...

Unexpected occlusion of the contralateral transverse sinus after stenting for idiopathic intracranial hypertension.
Authors: Coffman SA, Singh J, Wolfe S, Fargen KM Abstract A woman in her thirties with intracranial hypertension underwent stenting of the right transverse-sigmoid (TS) junction with resolution of the pressure gradient. Due to persisting symptoms at follow-up, she underwent a repeat study showing a patent right TS stent but the non-dominant left transverse sinus, patent on initial studies, was now completely occluded. According to the positive feedback loop hypothesis, stenting of the right transverse sinus should have resulted in a reduction in intracranial pressures (confirmed by post-stenting lumbar puncture), b...

Usefulness of contrast-enhanced and TOF MR angiography for follow-up after low-profile stent-assisted coil embolization of intracranial aneurysms.
This study aimed to assess the usefulness of time-of-flight (TOF) and contrast-enhanced (CE) magnetic resonance angiography (MRA) for follow-up after LEO Baby stent (LBS)-assisted coil embolization. Methods Twenty-four aneurysms treated with LBS-assisted coil embolization were evaluated. Researchers reviewed TOF MRA and CE MRA images in terms of occlusion and stent patency. Aneurysm occlusion was graded according to Raymond-Roy classification as follows: total occlusion (grade 1), residual neck (grade 2), and residual aneurysm (grade 3). Stent patency was scored as follows: occlusion (1), stenosis (2), and normal (3). Inte...

Conclusions The presence of an incorporated branch conferred a 20% absolute risk increase for delayed aneurysmal occlusion. Incorporated branches with a larger angle between the inflow jet and the incorporated branch direction exhibited a trend toward lower occlusion rates. This might be further investigated using a multicenter approach in conjunction with other potentially relevant clinical and angiographic variables.

The findings illustrated here lend support to the theory that the pathologic process of chronic SDH is repeated leakage of blood products from an inflamed, abnormal arterial neovasculature within the SDH membrane that arises from the MMA, and thus selective embolization could provide an effective treatment.
