Definition:
(n.) A clot of blood formed of a passage of a vessel and remaining at the site of coagulation.
(n.) A tumor produced by the escape of blood into the subcutaneous cellular tissue.
Example Sentences:
(1) The potential use of ancrod, a purified isolate from the venom of the Malaysian pit viper, Agkistrodon rhodostoma, in decreasing the frequency of cyclic flow variations in severely stenosed canine coronary arteries and causing thrombolysis of an acute coronary thrombus induced by a copper coil was evaluated.
