To assess predictors of outcome following endovascular treatment of small ruptured intracranial aneurysms (SRA). ⋯ Most patients with SRA can be treated with endovascular therapy and have limited complications. Overall predictors of outcome for patients undergoing endovascular treatment of SRA include age, aneurysm size, Hunt and Hess grade, location and post-treatment vasospasm.

We report the incidence and risk factors for contrast-induced nephropathy after the use of iodinated contrast for endovascular treatment of acute ischemic stroke. ⋯ The risk of developing CIN is low among patients with acute stroke who undergo emergency endovascular treatment. Treatment of acute stroke should be performed irrespective of Cr levels.

Verification of supraselective drug delivery for retinoblastoma using intra-arterial gadolinium.
We present a description of retinoblastoma treated with supraselective intra-arterial chemotherapy, demonstrating selective delivery of the infused chemotherapeutic agent into the tumor bed by MRI. A 7-month-old presented with group E (international classification) unilateral retinoblastoma. ⋯ Intraoperative MRI was obtained within 15 min after treatment and showed increased enhancement of the tumor and subretinal space. We demonstrate here that supraselective administration of chemotherapy into the ophthalmic artery appears to result in drug delivery to the tumor and subretinal space.

Little is known about how much protection a flow diversion stent provides to a non-thrombosed aneurysm without the adjunctive use of coils. ⋯ The flow diversion effects of both stents were limited to flow velocity reduction. In a non-thrombosed aneurysm or an aneurysm with delayed thrombosis, the intra-aneurysmal pressure remains essentially unchanged regardless of the level of the intra-aneurysmal flow velocity reduction induced by the stents.

Endovascular treatment of ruptured dissecting aneurysms of the posterior inferior cerebellar artery.
Dissecting aneurysms of the posterior inferior cerebellar artery (PICA) are rare, with optimal treatment strategies not well established according to the location of the aneurysm on the PICA. We present our single-center experience of endovascular treatment of ruptured dissecting aneurysms of the PICA. ⋯ Endovascular treatment of ruptured dissecting aneurysms of the PICA is safe and efficient.
