Blood clots can lead to a stroke, another name for an embolism that travels to the brain. Strokes can result in long-term disabilities including slurred speech, an inability to speak, one-sided weakness, and facial drooping, for example.
Clots are often associated with surgery. The reason is, the person is lying still during the procedure and potentially for many hours post-surgery. (Blood clots, as mentioned in my blog, can also form when an person is motionless for long periods of time, such as during airplane ride a long car trip. http://stroketales.blogspot.com/search?updated-min=2013-07-01T00:00:00-04:00&updated-max=2013-08-01T00:00:00-04:00&max-results=2)
The type of surgery you are having can also increase the risk of having blood clots after the procedure. If your surgery requires your arteries, veins, or tendons to be cut or repaired, the risk of a blood clot is higher because your body works to stop bleeding by forming clots.
The risk factors for blood clots both during and after surgery may include:
- History of Blood Clots: If you have had a blood clot in the past, your are more likely to have one in the future.
- Genetics: If your family is prone to clots, you may be, too.
- Atrial Fibrillation: Patients with an irregular heart beat have an increased risk of forming blood clots.
- Pregnancy: The chance of blood clots increase as the body makes blood clot faster in preparation for child birth.
- Cancer: Some types of cancer make blood clot more easily.
- Hormone Replacement Therapy (HRT): One known side effect of HRT is the increased risk of forming blood clots.
- Prolonged Immobility which include the time during anesthesia and recovering
- Heart Valve Issues people with replacement heart valves or heart valve problems have a higher risk of forming clots that can then travel to the lungs or brain.
After surgery, if you are able, get up and move during your recovery, one of the ways to prevent blood clots. Staying well hydrated by drinking ample amounts of water can also reduce your risk of forming clots, too.
One treatment for blood clots post surgery is heparin, a medication that is given by injection or by IV to prevent the formation of clots, to reduce the clots that already formed, or to keep the blood clots from getting larger. Another is Coumadin, or the generic Warfarin, given to help the body remove a clot from the bloodstream.
In cases where there is a high risk of the clot moving to the lungs or brain, especially after surgery, a device called an inferior vena cava filter (or Greenfield Filter) may be placed, which acts like a tiny porous vessel, catching clots before they can damage the lungs or brain. A small incision in the groin or neck is how the filter is put into place in the inferior vena cava. But the blood clots can break off and go to your lungs or brain anyway. That is how I had a pulmonary embolism. The filter can catch all, but sometimes not everything.
So you really have to hope for the best because the cold truth is, you never know what's gonna bite you in the ass next.
