| A '''venous thrombosis''' is a [[blood clot]] that forms within a [[vein]].
| |
| | |
| ''Thrombosis'' is a specific medical term for a blood clot that remains in the place where it formed. ''Superficial venous thromboses'' can cause discomfort but generally do not cause serious consequences, unlike the ''[[deep venous thrombosis|deep venous thromboses]]'' (DVTs) that form in the deep veins of the legs or in the pelvic veins.
| |
| | |
| Since the veins return [[blood]] to the [[heart]], if a piece of a blood clot formed in a vein breaks off it can be transported to the right side of the heart, and from there into the [[lung]]s. A piece of thrombus that is transported in this way is an ''[[embolism]]'': the process of forming a thrombus that becomes embolic is called a ''thromboembolism''. An embolism that lodges in the lungs is a ''[[pulmonary embolism]]'' (PE).
| |
| | |
| Systemic embolisms of venous origin can occur in patients with an [[Atrial septal defect|atrial]] or [[Ventricular septal defect|ventricular]] septal defect, through which an embolus may pass into the arterial system. This is termed a '''''paradoxical emboli'''''.
| |
| | |
| A pulmonary embolus is a very serious condition that can be fatal if not recognized and treated promptly.
