How long does it take to complete lower limb venous thrombosis surgery?

Lower extremity venous thrombosis surgery usually takes 1-2 hours to complete, depending on the location, extent and surgical method of the thrombus. Surgical methods include catheter thrombolysis, mechanical thrombectomy and venous filter implantation, and anticoagulant therapy and rehabilitation care are required after surgery.

1. Catheter thrombolysis is to inject thrombolytic drugs directly into the thrombus site through a catheter to dissolve the thrombus. It is suitable for acute thrombosis. The operation time is short, but the risk of bleeding needs to be closely monitored. Anticoagulants such as warfarin or rivaroxaban need to be continued after surgery to prevent recurrence of thrombosis.

2. Mechanical thrombectomy is to use special equipment to remove the thrombus from the blood vessel. It is suitable for larger or stubborn thrombus. The operation time is slightly longer, but the effect is significant. Anticoagulant therapy is required after the operation, and vascular ultrasound should be reviewed regularly to evaluate the recovery.

3. Venous filter implantation is to place a filter in the vein to prevent thrombus detachment and cause pulmonary embolism. It is suitable for high-risk patients. The operation time is short, but the filter may need to be left in place for a long time or removed later. Regular follow-up is required after surgery to monitor the position and function of the filter.

Postoperative rehabilitation includes moderate activities, wearing elastic stockings and diet. Moderate activities such as walking can promote blood circulation, and avoid sitting or standing for long periods of time. Elastic stockings can reduce swelling in the lower limbs and prevent recurrence of blood clots. In terms of diet, you should eat more fiber-rich foods, such as vegetables and fruits, and avoid high-fat and high-salt foods.

The surgical time for lower limb venous thrombosis varies depending on individual differences and surgical methods. Anticoagulant therapy and rehabilitation care are required after surgery to ensure treatment effectiveness and prevent recurrence.
