摘      要：Objective:This study aimed to explore the incidence of abnormal catheter positioning and the effectiveness and safety of intravascular adjustment or removal of abnormally positioned catheters through percutaneous *** and methods:A retrospective analysis was conducted on 58 patients with abnormal catheter positioning,treated between January 2009 and June *** adjustment of the migrated catheters and removal of the fractured catheters were performed through percutaneous puncture using a pigtail catheter,cobra catheter,and gooseneck ***:Of the 58 cases,there were 23 cases of catheter migration and 35 cases of catheter *** incidence of abnormal catheter positioning was 3.0%,corresponding to 1.2%migrations and 1.8%*** the 23cases of migration,1 case did not require adjustment and another underwent unsuccessful *** rate of successful adjustment of migrated catheters was 91.3%,whereas the rate of successful removal of fractured catheters was 100%.No surgery-related complications were observed either immediately or during the 1-month follow-up ***:This study showed that the incidence of abnormal catheter positioning is *** techniques used for the adjustment or removal of abnormally placed catheters are safe,efficient,and minimally invasive.
