 In this study, researchers examined the feasibility of using peripherally inserted central catheters, PICS, in children undergoing surgery for Moyamoya disease. The results showed that PICC insertion was successful in 22 out of 30 cases, with no complications reported. Furthermore, adjustments were made to the insertion depth in nine cases, resulting in a high success rate overall. This suggests that PICS can be used safely and effectively in pediatric patients with Moyamoya disease. This article is authored by Sanghwan Ji, Sol Ji Yu, Sun Yi Cho, and others.
