Recombinant plasminogen activa- tors are widely available and are used to treat myocardial infarc- tion, ischemic stroke, and pulmonary embolism.
As previously stated, ICU patients have multiple factors that leave them susceptible to clotting complications such as DVT, pulmonary embolism, and heparin-induced thrombocytopenia (HIT).
Surveillance ultrasonography and venog- raphy studies in ICUs have shown rates approaching 40%, and of cases that extend to the thigh, approximately 50% result in pulmonary embolism.
Pulmonary embolisms can range from clinically insignificant subsegmental clots found inci- dentally on a CT scan to a main pulmonary trunk embolus that causes hypoxia, hemodynamic instability, and death.
Large symptomatic pulmonary embolisms also may be treated by interventional radiologic procedures and in rare cases surgical thrombectomy. fte decision to use systemic anticoagula- tion or tissue plasminogen activator should not be made lightly because of bleeding risks.
