AI Article Synopsis
- - The study investigates how well minimally invasive surgery removes blood clots in patients with intracerebral hemorrhages (ICHs), finding that better clot removal is linked to improved patient outcomes.
- - Researchers aimed to enhance clot breakdown (fibrinolysis) using ultrasound in combination with two drugs, tenecteplase and urokinase, on clot samples made from human blood.
- - Results showed that the combination of ultrasound and fibrinolytic drugs significantly improved clot dissolution, especially for larger and older clots, highlighting the effectiveness of this approach.
Article Abstract
Adequate removal of blood clots by minimally invasive surgery seems to correlate with a better clinical outcome in patients with intracerebral hemorrhages (ICHs). Moreover, neurotoxic effects of recombinant tissue plasminogen activator have been reported. The aim of this study was to improve fibrinolysis using an intra-clot ultrasound application with tenecteplase and urokinase in our established ICH clot model. One hundred thirty clots were produced from 25 or 50 mL of human blood, incubated for different periods and equipped with drainage, through which an ultrasound catheter was placed in 65 treatment clots for 1 h, randomly allocated into three groups: administration of ultrasound, administration of 60 IU of tenecteplase or administration of 30,000 IU urokinase. Relative end weights were compared. This study found a significant increase in thrombolysis caused by a combination of ultrasound and fibrinolytic drugs, whereas ultrasound and tenecteplase are significantly more effective in the treatment of larger and aged clots.
