Orthopedic surgery and spine surgery have a high risk for postoperative venous thromboembolism.

Before you head home, discuss your risk of blood clots with your healthcare provider.

Blood clots after surgery can occur up to 90 days after the procedure.

Your healthcare provider may prescribe medication to prevent clots from forming.

Injectable medicationssuch asLovenoxorHeparinare very common during a hospital stay after surgery.

This medication is given to prevent the formation of a blood clot.

Lovenox, but not heparin, is less commonly prescribed for use at home.

Your surgeon may prescribe aspirin or another oral anticoagulant as prophylaxis if at high risk of venous thromboembolism.

This includes taking medications as directed and getting up and walking around.

Your healthcare provider may tell you to wearcompression stockingsto prevent blood clots after surgery.

These snug stockings use pressure to improve blood flow and prevent clots.

Heparin may also be given to prevent additional clots from forming or to prevent clots from getting bigger.

The filter may be in place temporarily or permanently.

Other options for DVT include percutaneous mechanical thrombectomy or catheter directed thrombolysis.

Treatment for a PE can include blood thinners or thrombolytics (medication that dissolves blood clots).

Thrombolytics can cause complications like sudden bleeding so they are used only for serious and life-threatening PE.

Signs of a Blood Clot

Not everyone with a blood clot will notice symptoms.

In fact, about half of people with DVT don’t show any signs at all.
