Evaluating thrombosis related to central venous catheters using advanced CT imaging

Official title: Autopsy and Photon Counting Computed Tomography to Evaluate Thromboses Related to Central Venous Catheters (PHOTO CAT)

Run by Region Skane · NCT06417541 · Data updated 2026-11-12

This study is testing a new type of CT scan to see how often blood clots happen in patients with central venous catheters, both in those who have passed away and those still living.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include deceased patients with an indwelling central venous catheter referred for autopsy and living patients with an indwelling central venous catheter referred for CT scans without contrast.

Probably not a fit

Patients with a glomerular filtration rate (GFR) less than 15 mL/min/1.73 m² may not benefit from this study.

What this trial studies

This study aims to assess the prevalence of subclinical thromboses associated with central venous catheters (CVCs) through the use of a novel photon-counting computed tomography (CT) scan. It consists of two sub-studies: one involving deceased patients with CVCs undergoing autopsy, and another involving living patients with CVCs referred for CT scans without contrast. The results from the photon-counting CT will be compared to findings from clinical autopsies to evaluate its diagnostic performance. The study seeks to enhance understanding of CVC-related thrombosis and improve imaging techniques.

Why it matters

Potential benefit: If successful, this study could lead to better detection and management of thrombosis in patients with central venous catheters, potentially improving patient outcomes.

How similar studies have gone: While studies have reported incidences of thrombosis in patients with CVCs, the use of photon-counting CT for this specific evaluation is a novel approach.
