Title: Blood Return System Dramatically Reduces Blood Loss During Pulmonary Thrombectomy

Researchers have reported that a novel blood return system reduces blood loss by 97 percent during pulmonary thrombectomy procedures for patients with pulmonary embolism.

The findings come from a study in which 40 patients were treated with the blood return system during aspiration pulmonary thrombectomy, while 90 patients underwent continuous aspiration without blood return. Using the blood return system resulted in a median blood loss of 10cc compared to 340cc in the control group, a statistically significant difference (p

Pulmonary embolism occurs when a blood clot blocks an artery in the lungs, often requiring intervention to restore blood flow. Mechanical thrombectomy is a minimally invasive procedure in which physicians remove blood clots from the pulmonary arteries using catheter-based devices. During such procedures, blood loss and the need for transfusions are common concerns that can complicate recovery.

The blood return system functions by filtering and returning the patient’s own blood during the thrombectomy process, thereby reducing the volume of blood lost and decreasing reliance on donor blood products. Researchers noted that while the system significantly lowered blood loss and transfusion requirements, it did not show a significant effect on procedural success rates or other clinical outcomes in the study.

Medical experts emphasize that minimizing blood loss during interventions is critical for patient safety, particularly in individuals who may already be hemodynamically unstable due to pulmonary embolism. Reducing transfusion needs also lowers the risk of transfusion-related complications and conserves blood resources.
