Electromagnetic Tracking of Devices During Interventional Procedures

NCT ID: NCT01279148

Last Updated: 2021-04-27

Basic Information

• Recruitment Status: WITHDRAWN
• Study Classification: OBSERVATIONAL
• Study Start Date: 2014-04-30
• Study Completion Date: 2015-01-31

Brief Summary

This prospective, randomized, controlled, parallel-design trial will compare the use of electromagnetic tracking and image guidance during biopsy/ablation procedures verses the typical standard or conventional image guided procedure alone (control). "US" ultrasound-guided biopsies/ablations with or without "CT" computed tomography- imaging will be used to complete the procedures in either the CT suite or a procedure room, at the discretion of the physician, and according to normal local practice patterns.

Detailed Description

The study will consist of approximately 300 patients from 1 sites. Each site will have a study group, where the physician will use the electromagnetic tracking system along with "US" ultrasound or "CT" computed tomography to complete the procedure and a control group, where the electromagnetic tracking system will be used, but the physician will be blinded to it and use only the typical, standard, conventional protocol, using US or CT, to complete the procedure. The expected completion time for enrollment is 12 months, but will depend on the ability of each Clinic to enroll patients.

Data and observations will be collected at a total of 2 scheduled appointments (screening and 1 study visit) or based on the current hospital workflow, which may combine these into one patient encounter.

Study Groups

Biopsy/Ablation - CONTROL GROUP

The tracking device will be placed on the patient's skin at the desired point of entry. Without displaying the PercuNav screen to the physician, a screen capture will be taken to record the approach path. At the point of insertion, the time stamp will be recorded and the start button will be pressed. Once the physician states they are at the defined target a screen capture will be taken on the PercuNav and the distance to target and time stamp will be recorded by pushing the start button again.

Biopsy/Ablation - STUDY GROUP:

The tracking device will be placed on the patient's skin at the desired point of entry. Without displaying the PercuNav screen to the physician, a screen capture will be taken to record the approach path. The physician will then be un-blinded and shown the PercuNav screen and will correct the desired approach path and another screen capture will be taken. At the point of insertion, the time stamp will be recorded and the start button will be pressed. Once the physician states they are at the defined target a screen capture will be taken on the PercuNav and the distance to target and time stamp will be recorded. At the end of the procedure, and if clinically indicated, a verification "CT" computed tomography scan will be taken with the needle in place and, sent to the PercuNav. Radiation dosage, due to CT imaging, will also be recorded.
