Imaging in acute ischaemic stroke: assessing findings in light of evolving therapies.

Acute ischaemic stroke (AIS) is a debilitating disease for which effective therapies are now available. Effective identification of candidates for therapy relies heavily on noninvasive imaging that must be interpreted accurately in a short timeframe. This review summarizes the evolution of AIS therapies and the implications for noninvasive imaging.

Declining complication rates with flow diversion of anterior circulation aneurysms after introduction of the Pipeline Flex: analysis of a single-institution series of 568 cases.

OBJECTIVEThe second-generation Pipeline embolization device (PED), Flex, has several design upgrades, including improved opening and the ability to be resheathed, in comparison with the original device (PED classic). The authors hypothesized that Flex is associated with a lower rate of major complications.METHODSA prospective, IRB-approved, single-institution database was analyzed for all patients with anterior circulation aneurysms treated by flow diversion.

Safety, immediate and mid-term results of the newer generation of hydrogel coils in the treatment of ruptured aneurysms: a multicenter study.

Objective: To assess the 'real-world' performance of the newer generation of hydrogel coils in ruptured aneurysms.

Methods: A multicenter retrospective study was carried out of angiographic and clinical outcome data on consecutive patients with ruptured aneurysms treated with at least 70% of the newer generation of hydrogel coils. Demographics and data on clinical grade, smoking, use of statins, aneurysm size, location, technique used, packing density, immediate angiographic result, angiographic follow-up, rebleeding and clinical outcome were obtained and analyzed.

Stenting Both before and after Coiling of a Ruptured Fusiform Basilar Aneurysm to Overcome Mechanical Occlusion Caused by Thrombosis within the Coil Mass. A Case Report.

Tortuous vessel anatomy reconstructed by stent-assisted coiling may be kinked by thrombus expansion within the coil mass. This can be overcome by placement of a second stent.
