E-146 The value of long-term angiographic follow-up following pipeline embolization of intracranial aneurysms

Abstract

Fisher exact test and in multivariate analysis using multiple logistic regression with bidirectional elimination based on the Akaike information criterion. In both univariate and multivariate analyses, statistical significance was corrected for multiple comparisons using the Benjamini-Hochberg method with a prespecified false discovery rate of 0.05. Results Complications occurred in 6.5% of procedures, including 1.9% neurological complications and 4.8% non-neurological complications. Permanent deficits occurred in only 0.2% of cases, corresponding to a single thromboembolic event. Overall, 0.5% of procedures resulted in major complications while 6.0% resulted in minor complications. Access site complications occurred in 0.7% of procedures and technical complications occurred in 0.3% of procedures. History of hypertension, history of ischemic stroke, and female sex were associated with an increased risk of complications, while femoral artery access was associated with a decreased risk of complications. Conclusions Pediatric cerebral angiography has a low rate of major or permanent complications. Children with history of hypertension, history of ischemic stroke, or female sex are at higher risk of complications, while use of femoral access carries lower risk of complications.

Machine learning to predict in-stent stenosis after Pipeline embolization device placement

“…In addition, ISS in most patients remain stable or even improved. These findings are consistent with previous studies (8)(9)(10)(11)(12)(13)(14). Reversible stenosis may be associated with thrombosis (25).…”

“…However, longterm complications of PED placement are not well understood. Previous studies have reported that most patients with ISS are asymptomatic and that ISS usually gradually improves; however, it may worsen (8)(9)(10)(11)(12)(13)(14). In addition, ISS may result in hemiplegia (14, 15) or even death (11) and cause decreased blood flow velocity (16).…”
