Anticoagulation is recommended for the treatment of pulmonary embolism (PE) and deep vein thrombosis (DVT). In some cases, an inferior vena cava (IVC) filter is used to prevent PE. We report the case of a 70-year-old woman who developed non-massive PE and proximal DVT, which were treated using an IVC filter; two filters were placed owing to the fracture of the filters. Few previous reports have discussed IVC fractures and the difficulty in detecting such fractures on computed tomography before retrieval. Based on our experience, we suggest that a temporary IVC filter for DVT treatment should be considered carefully.

Takotsubo cardiomyopathy (TC) is a temporal dysfunction of the left ventricle (LV) due to psychological or physiological stress; however, it rarely causes LV thrombus. We report a case of a 49-year-old woman who developed LV thrombi due to TC despite anticoagulation therapy. The thrombi caused acute systemic infarction, with the most severe occlusion being in the right renal artery. The patient underwent percutaneous catheter aspiration thrombectomy of the right renal artery and her renal function recovered shortly after. The results of this case suggest that catheter aspiration thrombectomy is effective in the treatment of thromboembolism in TC.
