Treatments for Blood Clots and Microclots
Updated October 30, 2026
No treatment has been shown in randomized trials to clear fibrin amyloid microclots or improve Long COVID or post-vaccine symptoms as of October 2026. The approaches below are being studied, at very different stages, and each card says how far the evidence has got.
Ultrasound for blood clots
Ultrasound is how doctors look for a large clot in a deep vein. In 2025 and 2026 lab-on-chip studies, low-frequency ultrasound also broke up amyloid microclots. It hasn't been tested in people.

Nattokinase broke down lab-made microclots in one 2024 preprint, but didn't significantly shrink plasma-derived microclots in a 2026 study. No study has measured microclots in people taking it.

Double filtration plasmapheresis filters large molecules such as fibrinogen and antibodies out of plasma, in courses of 2 to 4 weeks at Edogawa Hospital in Tokyo. Groups in Tokyo, Dresden and Berlin report improvements, but the data are early and mostly uncontrolled.

Triple therapy combines clopidogrel, aspirin and apixaban. The only published data come from an uncontrolled cohort of 91 patients, there are no randomized trials, and the combination carries real bleeding risk.
