Incidental Discovery of Retained Triple Lumen Catheter Guidewire

Experience with a triple-lumen catheter for autologous stem-cell transplantation

We relate our experience with the Cook (Cook Medial Inc., Bloomington, IN, USA), triple-lumen hyperalimentation (HAS) catheter for treatment related to autologous stem-cell transplant. Nineteen HAS catheters were implanted in the right jugular vein, and tunneled to the right anterior chest wall, under imaging guidance. Retrospectively, we reviewed each catheter. Three patient's experienced "bal...

A 20-year retained guidewire, should it be removed?

Management of the Retained Percutaneous Nephrostomy Catheter

Percutaneous nephrolithotomy is a widely accepted treatment for urinary calculi, but it is not without complications. We present the case of a 76-year-old male with a retained council tip catheter after percutaneous nephrolithotomy. Fluoroscopic guidance was used to perform percutaneous puncture of the catheter balloon, and the catheter was removed without complication. Advantages of various ne...

A novel guidewire approach for handling acute-angle bifurcations: reversed guidewire technique with adjunctive use of a double-lumen microcatheter.

Guidewire manipulation to negotiate branches originating at an acute angle from the parent artery is a frequently encountered challenge by the interventional cardiologist in clinical practice. To date, several methods have been developed, but none of them has a definitive success rate. Here, we report a technique for negotiating extremely angulated vascular bifurcations, with which we have achi...

Interactive physically-based simulation of catheter and guidewire

For over 20 years, interventional methods have improved the outcomes of patients with cardiovascular disease or stroke. However, these procedures require an intricate combination of visual and tactile feedback and extensive training periods. An essential part of this training relates to catheter or guidewire manipulation. In this paper, we propose a composite model to realistically simulate a c...
