What It Is
hrspheres narrow-size embolic microspheres are designed for use in embolization procedures to occlude blood vessels. They are intended for treating hypervascular tumors, hemorrhage, and vascular abnormalities.
Clinical Applications
Commonly used in transcatheter arterial embolization (TAE) and transcatheter arterial chemoembolization (TACE) for conditions like hepatocellular carcinoma and other hypervascular tumors.
Evidence Summary
The literature includes 10 studies, with types ranging from RCTs to case series, published between 2021 and 2025. These studies evaluate the device's efficacy and safety in clinical settings.
Reported Outcomes
Published studies report that hrspheres microspheres effectively occlude target vessels, improving outcomes in embolization procedures. They demonstrate enhanced embolization efficacy and controlled delivery to target sites.
Safety Profile
Reported complications include non-target delivery and transient arterial occlusion. However, the device's degradability allows for restoration of blood flow, potentially reducing long-term adverse events.
Evidence Limitations
Evidence gaps include the need for more large-scale RCTs to confirm long-term safety and efficacy. Some studies lack detailed safety data, and further research is needed to optimize device morphology and mechanical properties.
