Introduction
In general, interventional surgery for pulmonary artery embolism can involve catheter-directed local thrombolysis, which accelerates thrombus dissolution and restores normal pulmonary circulation. Catheter-directed local thrombolysis offers advantages such as a longer therapeutic time window and lower drug dosage. However, it is somewhat invasive; therefore, to avoid harm to the body, the procedure should be performed under the guidance of a qualified physician.
Under normal circumstances, interventional surgery for pulmonary artery embolism can involve catheter-directed local thrombolysis, which accelerates thrombus dissolution and restores normal pulmonary circulation. The specific procedure is as follows:
1. Position the patient in a supine position, establish an intravenous access, and administer anesthesia.
2. Perform femoral vein puncture, insert a catheter, advance it through the right atrium and right ventricle, and position the catheter tip in the main pulmonary artery.
3. Inject contrast agent to visualize the pulmonary artery and identify the location of the blockage.
4. Gradually advance the catheter to the site of the thrombus and deliver thrombolytic agents such as streptokinase or urokinase.
5. After completing the injection, remove the catheter and apply local pressure for 10–15 minutes followed by compression dressing.
Catheter-directed local thrombolysis offers advantages such as a longer therapeutic time window and lower drug dosage. However, it is somewhat invasive. To avoid potential harm, the procedure should be performed under the guidance of a qualified physician.
