How can you get blood clots during surgery?

ANSWER

Sometimes, the surgery itself can cause a blood clot. Long procedures where you're lying on the operating table for many hours allow your blood to settle and pool, which makes it easier to clot. Tissue, debris, fat, or collagen could get released into your blood system during an operation, making blood thicker around those particles. Blood clots can also form if your veins are damaged during an operation. Surgeries that involve scraping or cutting into a bone, such as a hip replacement, may release substances known as antigens. These antigens trigger your body's immune system and can lead to clots.
