Abstract
Background
There has been growing interest in transradial procedures over the past decade due to substantial reductions in access site complications as well as improved patient recovery. While several radial-specific neurovascular catheters have come to market, all catheters that are compatible with a 7Fr sheath have small inner diameters (IDs) (0.079″–0.082″), which can limit use of modern intermediate catheters. while larger-ID catheters cannot be used with a radial sheath resulting in complications related to radial artery spasm and entrapment. We report our results using a novel 7Fr-sheath-compatible radial guide catheter with an 0.087″ ID (Piraeus 7Fr 87 NeuGlide catheter) for neurovascular procedures.
Methods
This is a single center retrospective case series of patients undergoing transarterial transradial neuroendovascular procedures using the Piraeus 7Fr 87 NeuGlide catheter. The primary outcome was delivery of the catheter to the target vessel and successful completion of the procedure without the need to convert to femoral access or an alternative guide. Descriptive statistics are reported.
Results
Forty patients were included. The most common procedure was middle meningeal artery embolization followed by aneurysm embolization. And 97.5% of procedures were completed successfully without conversion to femoral access; 75% were completed without the need of an intermediate guide catheter. One procedure required conversion to femoral access. There were no access site or neurological complications.
Conclusion
The Piraeus 7Fr 87 NeuGlide catheter is both safe and effective for neurovascular procedures. The larger ID and 7Fr compatible outer diameter allows for the use of standard 5Fr and 6Fr intermediate/aspiration catheters.
