We successfully performed embolization therapy for a pelvic arteriovenous malformation by the retrograde transvenous approach using a liquid embolic material. This malformation was unique in that it had a single draining vein, which allowed this technique employing an occlusion balloon.  相似文献

Abstract A case of pulmonary embolism showing a longstanding solitary pulmonary nodule is presented. An asymptomatic 57 year-old man with a solitary nodule in the right lower lobe was referred to our hospital. A pulmonary perfusion-ventilation scan following a sudden onset of dyspnoea established the diagnosis of recurrent pulmonary embolism. The nodule gradually disappeared after anticoagulant treatment, indicating that the nodule was pulmonary infarction from silent pulmonary embolism. Although the incidence of pulmonary infarction is low in Japan, this case suggests that pulmonary infarction from silent pulmonary embolism should be considered as one important cause of a solitary pulmonary nodule.  相似文献

There have been only two cases reported of intracranial tumor with extracranial metastasis through an artificial channel. The authors present another valid example of glioblastoma with distant metastases through a ventriculopleural shunt to the right thorax. With the review of the cases reported in the literature, they discuss such points as type of tumor, site of metastasis, survivial time, and latent period from onset, from operation, and from irradiation to an evidence of metastasis. The followings are considered: the long survival may certainly play a role but may be unnecessary for occurrence of extracranial metastases; surgical procedure and/or irradiation play an important role in glioblastoma; the bone is the most favored site of metastasis and the three major locations, namely bones, lung and pleura, and lymph nodes consist of more than three-fourth of all metastatic sites; the metastatic ratio and its index are proposed by the authors for further discussion; there are many factors concerning the occurrence of extracranial metastases of intracranial tumors, but some factors are merely theoretical.  相似文献

Lymphangioma of the large intestine   总被引:1,自引:0,他引:1  
Lymphangiomas of the large intestine have been reported more frequently since the development and widespread use of the colonic fiberscope. It is possible to endoscopically diagnose lymphangiomas because they are lustrous and smooth on the surface, pliable on compression, and half of them have a stalk or a waist at the base. Lymphangiomas of the colon and rectum under 20 mm in diameter can be safely resected by electrocautery, thereby avoiding unnecessary operation.  相似文献
