[Evaluation of a novel seldinger-needle for computed tomography guided interventions: initial experiences]

Area of Science:

• Radiology
• Interventional Radiology
• Medical Devices

Background:

• Computed tomography (CT)-guided interventions are crucial for diagnosis and treatment.
• Difficult anatomical access and patient factors can complicate these procedures.
• Novel devices are needed to improve safety and efficacy in challenging interventional scenarios.

Purpose of the Study:

• To evaluate a novel 20G-Seldinger needle for CT-guided interventions.
• To assess its applicability and performance under difficult conditions.
• To identify the advantages and drawbacks of this new device.

Main Methods:

• A prospective study involving 16 patients undergoing CT-guided interventions (drainage, biopsy, ablation).
• Utilized a new Seldinger needle with an integrated guide wire and continuous anesthesia delivery.
• Procedures were performed under challenging conditions, with outcomes including success rate, complications, and patient pain scores.

Main Results:

• All 16 interventions were successful with no severe complications.
• The Seldinger needle facilitated access to difficult regions in 15 out of 16 cases.
• Patient tolerance was excellent, with a mean pain score of 2 ± 1.

Conclusions:

• The novel Seldinger needle is a reliable and safe technique for CT-guided interventions.
• It enables successful procedures even under difficult conditions.
• The device offers advantages in terms of ease of use and patient comfort.
