Fellows’ Journal Club Delayed leukoencephalopathy is a rare complication that occurs after endovascular coiling of cerebral aneurysms and is found in the literature with several different names, such as delayed leukoencephalopathy, delayed enhancing lesions, and delayed multiple white matter lesions.
Fellows’ Journal Club The authors’ aim was to analyze the outcomes after flow diversion among nonsaccular unruptured lesions. Fifteen studies (213 aneurysms) were included in the analysis. The long-term adequate occlusion rate was 85.3%. Treatment-related complications were 17.4%. Overall, 15%
Editor’s Choice Does Embolization with Larger Coils Lead to Better Treatment of Aneurysms (DELTA) was an investigator-initiated multicenter prospective, parallel, randomized, controlled clinical trial. Patients had 4- to 12-mm unruptured aneurysms. Treatment allocation to either 15- (experimental group) or 10-caliber
Editor’s Choice The authors subjected 40 aneurysms (37 unruptured, 3 ruptured) to 4D flow MR imaging. They visualized streamlines with velocities below the threshold—that is, a percentage value of the aneurysm maximum inflow velocity—and progressively decreased the threshold to identify
Editor’s Choice The authors enrolled 10 patients with intracranial aneurysms, treated with flow diverters between September 2014 and December 2018, who experienced postoperative aneurysm rupture. They matched these subjects 1:2 with 20 with postoperative unruptured intracranial aneurysms based on clinical
Fellows’ Journal Club Thirty-five patients with high-grade, symptomatic intracranial stenosis and poor antegrade flow, treated with intracranial angioplasty without stent placement from January 2010 to December 2016, were retrospectively reviewed. The main outcomes included the changes in antegrade flow and
Saad EA. Portal Hypertension: Imaging, Diagnosis and Endovascular Management, 3rd Ed. Theime; 2017; 344 pp; 242 ill; $149.99 Portal hypertension is an end-stage manifestation of liver cirrhosis with numerous, potentially life threatening and life-altering manifestations. Radiology, and specifically interventional radiology,
Fellows’ Journal Club The authors report their single-center experience in 22 patients with dural arteriovenous fistulas who were treated with transarterial liquid embolization in combination with transvenous balloon-assisted protection of the affected venous sinus. All patients were symptomatic, of whom
Fellows’ Journal Club Prospectively managed stroke data bases from 2 separate centers were retrospectively studied between 2009 and 2014 for records of tandem occlusions related to internal carotid dissection. The first step in the revascularization procedure was intracranial thrombectomy. Then,
Fellows’ Journal Club From the MR CLEAN data base, all baseline thin-slice CTA images of patients with acute ischemic stroke with intracranial large-vessel occlusion were retrospectively collected. The quantitative collateral score was calculated as the ratio of the vascular appearance
