Popis: Purpose: To compare the high-resolution CT features of bleeding foci in patients with massive hemoptysis during embolization with those revealed by angiography. Materials and Methods: Between June 1997 and June 1999, we evaluated 25 patients who from among a total of 49 with arterial embolization due to massive hemoptysis underwent HRCT prior to embolization. We retro-spectively analyzed medical records, and angiographic and HRCT findings. The time interval between HRCT and arterial embolization varied from two hours to six days. Angiography indicated that the bronchial, intercostal and internal mammary artery, and branches of the subclavian, were the foci of bleeding, and indicated the location of these in each pulmonary lobe. The HRCT findings were evaluated in terms of cavity, air-menis-cus sign, bronchial dilatation, consolidation, ground-glass opacity, and fibrotic scar. We analyzed the corre-sponding sites of HRCT and the angiographic findings of the foci of bleeding. Results: In 24 of 25 patients, the foci of bleeding were angiographically confirmed, their presence being noted in 28 pulmonary lobes. HRCT findings corresponding to the bleeding foci revealed by angiography were the air-meniscus sign (8 of 10 lobes, 80.0%), cavity (7 of 9 lobes, 77.8%), bronchial dilatation (21 of 30 lobes, 70.0%), and fibrotic scar (1 of 23 lobes, 4.3%). The findings in areas of consolidation and/or ground-glass opacity only did not correspond, however. Conclusion: As compared with those revealed by angiography, the HRCT features of bleeding foci in patients with massive hemoptysis during embolization are in order of frequency, the air-meniscus sign, cavity, and bronchial dilatation.
