Difference Between DVT and PE in the Blood

I'd like to start this article out on a personal note to let you know how I came to know about this life threatening condition.

My friend had surgery one day as an outpatient, this means the doctors schedule the appointment for the surgery, the patient comes in and has the procedure done, then goes home after spending an hour or so in a recovery bed. The recovery bed routine is done to make sure the patient regains consciousness and has normal vital signs - such as heart beat and blood pressure.

My friend had the surgery, then came home and seemed okay except for some slight grogginess. However, a few hours after being home, he just scooted to the edge of his seat and collapsed into the floor, unconscious.

He was rushed to the hospital and diagnosed as having PE. This condition is when a piece of blood clot travels through the body/veins and winds up getting stuck someplace where blood needs to keep flowing. In his case, it was his lungs. When a blood clot starts in one part of the body and moves to another part, the clot takes on a new name called embolus. In other words, there's an embolus on the loose and it is a Serious situation, folks!

Usually, before PE sets in, there is another condition that occurs. This is known as DVT, a blood clot that builds up - usually in the legs - deep down in the veins. This can happen to patients who've been under the knife and/or lazing around in a hospital bed for hours (or days) on end. It is like the circulation goes out of whack and the blood seems to go to sleep.

Fortunately, the blood does clot up normally, doing its job after surgery, but the downside is when blood clots occur in the wrong place, such as the thigh or calf, it's not like you can take a bunch of blood thinning agents while your surgery wound is trying to seal up. Being dormant poses risk for clotting as well. This is why PE is the unseen killer responsible for more than a quarter of the nation's population who die while staying in the hospital.

Here's a simple recap. A patient may have deep vein thrombosis (a blood clot usually in the leg), and then it can become life threatening when the clot breaks apart and travels (it becomes an embolus) to the lungs or other organs - that's when it turns into a deadly pulmonary embolism (such as a blockage in the lungs). This can kill a person within hours if treatment is not given immediately.
