These authors describe the use of 2 intra-aneurysmal catheters to deploy first large coils and then smaller, more traditional coils that ultimately fill the interstices left by the larger coils until aneurysms are tightly packed. When this technique was used to occlude large/giant aneurysms, follow-up angiography revealed no recurrences compared with nearly 40% in a group of similar lesions treated in conventional fashion.

Nine studies encompassing nearly 2000 patients treated with or without anesthesia for acute stroke were analyzed. Patients with acute ischemic stroke undergoing intra-arterial therapy may have worse outcomes with general anesthesia compared with conscious sedation. However, the difference in stroke severity at the onset may confound the comparison in the available studies.
