What's the difference between phlebolith and thrombus?
Phlebolith
Definition:
(n.) A small calcareous concretion formed in a vein; a vein stone.

(20) In 3 of the patients calcified opacities, resembling phleboliths, were demonstrated on plain X-ray examination.
Thrombus
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.
(2) In the six cases of aortic aneurysm, three had platelet deposition within their aneurysms, and surgery was performed for these positive cases, but one of them had no thrombus.
(3) Magnetic resonance imaging and venacavography appear to be the most sensitive means of identifying tumor thrombus.
(4) In venous thrombi, soluble fibrin and fibrinogen exhibited maximum thrombus-blood ratios when they were injected 4 hours after thrombus induction; the thrombus-blood ratio was greater for soluble fibrin than it was for fibrinogen when these agents were injected 4, 8, or 24 hours after thrombosis induction.
(5) Echocardiograms showed good left ventricular function and a large coil of apparent thrombus in the right atrium prolapsing into the right ventricle.
(6) Removal of left atrial ball thrombus and mitral valve replacement was performed in two patients successfully.
(7) On CT scans the tumor thrombus usually appeared as an endoluminal filling defect surrounded by a rim of contrast material.
(8) Since the antithrombin action of heparin fails to interrupt arterial thrombosis, a mediating role for thrombin (EC 3.4.21.5) in the formation of high-shear platelet-dependent thrombus has been unproven.
(9) Waiting for surgery the patient suffered a syncope that was diagnosed of embolic origin and the left atrial thrombus has disappeared.
(10) The effect of initial perturbation of the thrombus by a guide wire appears to be less important than the thrombus disruption and accelerated thrombolysis caused by the pulsatile delivery system.
(11) Chronic atrial fibrillation is generally thought to cause stroke by atrial thrombus formation with subsequent embolization.
(12) Furthermore apo (a), which shows extensive sequence homology with plasminogen, may promote the deposition of lipoprotein (a) in the artery and interfere with fibrinolytic processes following inappropriate thrombus formation.
(13) Thrombolysis between postoperative day 2 and day 9 seemed to dominate over thrombus formation and propagation.
(14) De-airing of the acute ventricular assist device using the designed port has resulted in thrombus formation at the site of device puncture in three of four ventricular assist devices in place during long-term (more than 72 hours) support.
(15) In deep injury, tears extend from the lumen into the depths of the intima and often enter a lipid pool; in consequence, thrombus initially forms within the plaque, thereby altering its configuration and expanding its volume.
(16) The patency of chronically implanted intravascular cannulae is usually limited by thrombus formation at the cannula tip.
(17) Therapy to eliminate thrombus included surgery (two cases), anticoagulation with warfarin (three cases) and streptokinase thrombolysis (one case).
(18) In 1952, Clarence Agress performed an experiment on dogs to demonstrate his idea that a thrombus in a coronary artery could be dissolved without harm to the myocardium.
