(A) Computed tomography pulmonary angiography (CTPA) demonstrates pulmonary embolism (PE). (B) Computed tomography pulmonary angiography (CTPA) demonstrates that residual thrombus markedly improved.

PE, especially the bifurcation of the main pulmonary artery, the posterior basal segment of the dorsal segment of the right inferior pulmonary artery, and the posterior and external basal segment of the left upper pulmonary artery by computerized tomography pulmonary arterial angiography (CTPA) (Figure 1A). Pervasive deep thrombosis was also visible in the bilateral posterior tibial and calf intermuscular veins by ultrasound Doppler. Following this initial week, CTPA was repeated to evaluate the residual thrombus, which was markedly improved (Figure 1B).

The embolus catheter was inserted in the right pulmonary artery and continued to suction for 100 s, then a repeated pulmonary angiogram demonstrated a substantially improved blood flow to the right lung (Figures 2A-C).
