What this trial studies

This study aims to evaluate the feasibility of a novel device using Photoacoustic Flow Cytometry (PAFC) to detect circulating blood clots (CBCs) in patients diagnosed with thromboembolic disease. Current methods for detecting CBCs have poor sensitivity, especially when low numbers are present, leading to potential complications from undetected clots. By improving detection capabilities, this approach could enhance patient outcomes and reduce risks associated with thromboembolic conditions.

Who should consider this trial

Good fit: Ideal candidates include men and women aged 18 and older with diagnosed venous or arterial thromboembolic disease.

Not a fit: Patients with conditions requiring immediate surgical intervention for thrombus removal or those with severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better detection of blood clots, reducing complications and improving treatment outcomes for patients with thromboembolism.

How similar studies have performed: While there is limited data on the specific use of PAFC for this purpose, the study represents a novel approach to improving the detection of circulating blood clots.
