[Intravascular ultrasound and angioscopy].
We observed pulmonary artery thrombi and parietal lesions in patients with acute pulmonary thromboembolism (APTE), using intravascular ultrasound (IVUS) and angioscopy (AS). In APTE without underlying disease mainly non-echorich intraluminal mass was noted, with a pulsatile and thin intima. On AS red thrombi with white fibrin coating could be directly observed, and no parietal lesions were found. The findings of the pulmonary arterial intima and thrombus were different between APTE and chronic pulmonary thromboembolism (CPTE), and even among CPTE cases. IVUS and AS are useful in characterizing the thrombi and related pulmonary artery lesions in PTE.
