Grateful for your thoughts. 4F pressure injectable polyurethane PICC same make placed in three different patients. Different Lot numbers developed small horizontal split. My concern is that these splits occured within the vein.
1. 400+ dwell days: Removed as occuded. 2 mm split at 20cm point (around axilla). Company attributed to fatigue from repetitive joint movement.
2. 150+ dwell days. Patient with history of frequent status epilepticus. Following fall user noticed leak on flushing. Removed: 2mm split at 12 cm point. Never used for CT contrast.
3. 50+ dwell days. patient walking with crutches. PICC blocked and removed. 2mm split found at 8 cm point (PICC placed high up on arm to avoid pressure from the crutch). Never used for CT contrast
All PICCs secured by a subcutaneous device. We have decided to go back to a silicone PICC for our community patients. I have noticed the PICCs of a few manafactures kink easily and with repitition a pale fatigue line develops (a bit like the collapse and marking in an acutely bent and flexed cardboard tube). No harm resulted in these cases and with hindsight the second two patients will have placed focal repetitive movement on the limb. Has anyone had similar experiences?
