Treatment of pulmonary embolism is usually given with interventional therapy and medication, and the total cost of treatment is usually around 30,000 yuan, including interventional thrombolysis given by the interventional department, which costs 25,000 yuan. After returning to the ward, comprehensive observation and treatment means such as anticoagulation, thrombolysis, oxygen and cardiac monitoring are still needed, and the total cost is around 5,000 yuan, and the hospital stay is usually 7-10 days. If the pulmonary embolism is effectively relieved by imaging review and clinical symptoms disappear, placement of lower limb filters is not required. If there is still thrombosis after thrombolysis and anticoagulation, a lower limb filter needs to be given, and the cost of the procedure will increase again by about 10,000 RMB. Therefore, the cost of treatment for pulmonary embolism depends on whether the lower limb filter needs to be placed and the length of hospitalization after treatment by drug thrombolysis, and the total cost is usually about 30,000 RMB.
