To the Editor: Peripherally inserted central catheters (PICCs) are a common way of intravenous access to provide long-term treatment and parenteral nutrition in preterm and term infants [1, 2]. A 30-wk-5-d-old baby with a birth weight of 1770 g was transferred to neonatal intensive care unit after birth on the presumed diagnosis of prematurity and respiratory distress. The umbilical vein catheter was placed initially and an antibiotics regimen of ampicillin plus gentamicin and total parenteral nutrition were initiated. Also respiratory support to the patient was given with nasal continuous positive airway pressure. On the 11th day of his hospitalization, the patient’s antibiotic treatment and partial parenteral nutrition were still continuing when the umbilical vein catheter got spontaneously dislocated. So, a 24 G (2 Fr) PICC line was placed to the right cephalic vein at 16 cm length. After locating the tip of the catheter by direct radiography, and ensuring that it was correctly placed, the heparinized PICC line was started to be used. Three days later, the infusion pump gave an alarm for sudden occlusion, and the fluid flow was stopped. Although no intervention was performed after placing it, the catheter was seen to be knotted on direct radiography. So it was removed by a careful and gentle pulling out process. The resting treatment was completed via peripheral vein access in the following days and the patient was discharged with full recovery on the postnatal 35th day. By reporting this case, we want to bring to the clinician’s attention that with the increasing frequency of PICC placement in newborns, a clinician should take into account knotting possibility of PICC while formulating the differential diagnosis when faced up to a malfunctioning line, in order to prevent potentially associated complications.
