Ascent™: a novel balloon microcatheter device used as the primary coiling microcatheter of a basilar tip aneurysm.
Intracranial aneurysms undergoing balloon-assisted endovascular repair are particularly challenging given the concurrent use of one or more catheters in addition to the primary coiling microcatheter. Here, we describe a previously unreported novel device where a balloon catheter was used as the primary coiling microcatheter, thereby eliminated the need for additional catheters.

The best therapeutic approach in patients with acute basilar artery occlusion (BAO) remains unclear. We report the results of a combined treatment approach with intravenous (IV) abciximab and intraarterial (IA) tissue plasminogen activator (tPA) in these patients. ⋯ Combined treatment with IV abciximab and IA tPA yielded a high recanalization rate in patients with BAO. However, functional outcomes were poor, potentially due to late initiation of treatment. Early treatment might improve functional outcome.

We investigated whether combined transcranial Doppler (TCD) and magnetic resonance angiography (MRA) can diagnose significant stenosis (s-stenosis) of the siphon portion of the internal carotid artery (S-ICA) on digital subtraction angiography (DSA). ⋯ Combined TCD and MRA examinations have similar diagnostic power to DSA.

This report describes a rare complication in a woman who underwent thoracic spinal surgery. One month postoperatively, her rehabilitation was interrupted by the development of a severe headache, nausea, vomiting, and a right-side occulomotor nerve palsy. ⋯ The CSF was seen to track into the right pleural space via a dural-pleural fistula. Surgical repair of the fistula led to a definitive resolution in symptoms, thus highlighting the importance of early recognition of this highly unusual complication.

Multimodal CT with CT angiography (CTA) and CT perfusion (CTP) are increasingly used in stroke triage. Our aim was to identify parameters most predictive of hemorrhagic transformation (HT), especially symptomatic intracerebral hemorrhage (SICH). ⋯ For acute MCA infarcts ≤ 9 hours, the strongest predictor of SICH on multimodal CT was ASPECTS on CTA-SI.
