Occlusion (medicine)
The occlusion (from latin occludere 'closing) (clutch, closing, blocking, inhibition) is the closure of a hollow organ (eg. As a vessel), or a body passage. Occlusion can be caused by the body's own tissue or material as part of a disease (e.g. PAD ) or it can be carried out by the doctor using instruments (e.g. vascular clamps) as part of a surgical procedure.
Examples
- Ureter occlusion (percutaneous) is the artificial closure of the ureter by a silicone olive , i.e. H. the natural path of urine from the kidney to the bladder is interrupted. Instead, the urine is drained percutaneously, i.e. through the skin, directly from the kidney.
- In ophthalmology , the term occlusion is used to describe the targeted covering of an eye (e.g. with eye patches ) to eliminate double vision , for diagnostic purposes ( Marlow bandage ) or to treat amblyopia in children.
- A variant of hydrocephalus is called hydrocephalus occlusus , because the CSF accumulates due to a mechanical flow obstruction (e.g. in chronic aqueduct stenosis ).
- Closure of the airways
