The Groshong catheter: initial experience and early results of imaging-guided placement.

Abstract

Fifty Groshong catheters were placed in 50 patients with use of ultrasound (US) and fluoroscopic guidance in the radiology suite: 49 were placed via the subclavian vein and one was placed via the left internal jugular vein. All (100%) attempts at catheter placement were successful. Imaging guidance affected the placement of catheters in 12 cases (24%), including four patients (8%) in whom vascular access would not have been possible with blinded percutaneous venipuncture or surgical cutdown. After a four-case learning curve period, during which one pneumothorax (2%) and two arterial punctures (4%) occurred, there were no further venipuncture-related complications. One catheter was removed because of infection (2%) and one because of allergic reaction (2%) to the antimicrobial cuff. Four patients with cutaneous infections and one with catheter-related sepsis were successfully treated with antibiotics. Results demonstrate the initial promise of imaging-guided placement of central venous access catheters when performed in the radiology suite.
