Abstract:
Objective To evaluate the clinical value of ~(99m)Tc-MAA imaging in patients with lower extremital posttraumatosis and postoperation(LEPP).Methods 21 LEPP patients with clinical highly suspected acute pulmonary embolism(APE) underwent ~(99m)Tc-MAA veins imaging and pulmonary perfusion imaging(PPI).Vena caval filters were inserted and thrombolysis were given in patients with big area APE and/or iliofemoral vein thrombosis indicated by ~(99m)Tc-MAA imaging.Thrombolysis was given in patients with small area APE and/or subpopliteal vein thrombosis.PPI was reexamined after 2～4weeks` treatment.The lung segments with 100% lack of perfusion were marked 3,those with 25%～75% were marked 2,those with less than 25% were marked 1 and normal was marked 0.The therapeutic results were assessed using this marking system.Results There were 13 patients with big area APE,8 with small area APE,14 with iliofemoral vein thrombosis,and 7 with subpopliteal vein thrombosis.2 cases(9.5%) died before thromobolytic therapy.The marks were significant different before(10.2?3.8) and after(2.8?1.4) treatment(t=7.75,P
