The Vessel Dilator for Central Venous Catheter Placement: Forerunner for Success or Vascular Misadventure?

Abstract

The vessel dilator for central venous catheter placement: forerunner for success or vascular misadventure? J Intensive Care hled 2001;16:263-269.During placement of a central venous catheter (CVC), the vessel dilator and/or combination dilator/sheath-introducer are recognized as potential causative agents in numerous traumatic complications that may be erroneously ascribed to the catheter, placement needle, or guidewire. A review of the literature and device-user sun-eyare offered in support of the need for additional training in safe dilator use, as well as the need to address device labeling and device design.From the 'Food and Drug Administration, Ccnter for Devices and Radiological Health, Office

Lock and dock: Two-step transvenous retrieval of a fractured femoral sheath with a vascular snare via the right internal jugular vein

“…Nevertheless, internal jugular catheterization generally carries risks of mechanical complications such as pneumothorax, hemothorax, and arteriovenous fistula associated with arterial puncture [ 6 ]. Additionally, a previous report has shown that mechanical complications can also occur when using dilators for insertion of large-diameter sheaths [ 7 ]. The use of ultrasound guidance has been shown to reduce the risk of these mechanical complications [ 8 ].…”

Folded large-bore central catheter in the right internal jugular vein as shown by ultrasound: a case report

“…Mechanical complications such as hemothorax, cardiac injury, and arteriovenous fistula can occur when using a dilator. 6 Dilators that are used for insertion of large-bore catheters are stiffer and thicker than those used for insertion of conventional catheters. A thick dilator can damage blood vessels other than the target vessel.…”
