Given the history and clinical findings, a computer tomography pulmonary angiogram (CTPA) was performed and confirmed the presence of a saddle PE (Figure 1) with thrombus occluding the right main pulmonary artery, left upper lobe segmental artery, and left interlobar artery.
CTPA performed four days post thrombolysis with reduction of pulmonary embolism (arrows).

A repeat CTPA was performed on the fourth day of admission which revealed a substantial decrease in clot burden, no visible saddle embolus, and reduced right heart strain (Figure 2).
CTPA performed six months post thrombolysis with resolution of pulmonary embolism (arrows).
