Interventional radiologic placement of Hohn central venous catheters: results and complications in 100 consecutive patients.
Hohn catheters are single- or double-lumen catheters used for intermediate-length central venous access. The authors report their technique, results, and long-term follow-up in a prospective study of their first 100 consecutive patients. ⋯ Technical success, complication, and long-term patency rates for the Hohn catheter are comparable to or better than those in most surgical series involving tunneled external catheters. The Hohn catheter is an excellent alternative for intermediate-length central venous access. Hohn subclavian catheter placement has become a standard part of the authors' interventional radiology service and is easily adaptable to all interventional practices.
