A case of deep femoral artery aneurysm under continuous oxygen therapy for chronic respiratory failure was treated successfully by arterial ligation. The ligation of the deep femoral artery was easy and simple. This procedure may be indicated in poor risk patients or cases of ruptured aneurysm.

We report the efficacy of catheter-directed thrombolysis (CDT) for acute deep vein thrombosis. Between January 2003 and August 2004, 20 patients were treated with CDT for occlusive femoral, ilio-femoral and vena caval thrombosis, for less than 2 weeks from onset. Average age was 56.4 years (range 30-78 years), 11 patients were male, and the duration of leg symptoms was 4.4 days (range 1-12 days). Routine temporary inferior vena caval filters were used, and a multi-lumen catheter was inserted from the popliteal vein. Urokinase was used via the catheter by the combination drip infusion method and pulse-spray method. All patients received heparin and stasis of venous flow was prevented with intermittent pneumatic compression. If thrombus remained, mechanical thrombolysis was necessary. Metallic stents were implanted for iliac vein compression syndrome and organized thrombus. Venographic severity score (VS score) and extremity circumference were used to evaluate the effects of treatment. The duration of the treatment was 5.0±0.28 days (range 2-9 days) and the total dosage of urokinase was 1, 025, 000±57, 000 units (range 360, 000-1, 680, 000 unit). One (5%) iliac vein compression syndrome and two (10%) organized thrombi were treated by implanted metallic stents. Giant thrombi was captured by temporary inferior vena caval filters in two patients, but there was no pulmonary embolism. Two patients had thrombophilia, one was antiphospholipid syndrome and one was protein S deficiency. There was an early recurrence in one patient and re-CDT was needed. The VS score deteriorated to 6.2±2.5 (post CDT) significantly (p<0.0001) from 26.2±6.3 (pre CDT). CDT for acute deep vein thrombosis was effective and its early outcome was acceptable.

A 79-year-old man, who had a history of intravesical instillations of bacillus Calmette-Guérin (BCG) therapy for urinary bladder cancer, developed bloody sputum 4 years after BCG therapy. BCG was detected from the sputum by detailed examination. Medical therapy for tuberculosis (TB) was started, but bloody sputum continued. Computed tomography (CT) for the chest was performed to evaluate the state of TB, and surprisingly, found impending rupture of tuberculosis mycotic thoracic aneurysm. He was emergently transferred to our hospital. CT revealed that the aneurysm made a lump with surrounding lung and lymph nodes. It seemed to be quite difficult to dissect and to be quite high risk to perform graft replacement with pneumonectomy. On the other hand, TB infection was controlled with antibiotic therapy. Thus we chose debranch TEVAR for this complicated situation. His bloody sputum regressed soon after the procedure and disappeared during his hospitalization. He was discharged home on POD 13 without serious complication and continued to have antibiotic therapy under the instruction of his primary physician.

  On July 7, 2010, a 74-year-old man came to our hospital, complaining that he had a nagging pain in his chest that started the preceding day. After performing electrocardiography, blood tests and electrocardiography, we diagnosed the case as acute myocardial infarction. At first, it was thought that blood flow could be restored in due course of time, antiplatelet and anticoagulant agents were used. Intracardiac catheterization was not included in our initial treatment plan. Three days after the initiation of the treatment, the patient had pain in his left inguinocrural region. Computed tomography and magnetic resonance imaging reveled hematoma in his left iliopsoas muscle. We stopped administering antiplatelet and anticoagulant agents to him. But anemia progressed from Hb14.1g/dL to 9.8 g/dL, so blood transfusions had to be given. After that, the patient underwent a rest cure. With the passage of time, the pain and swelling of the left iliopsoas muscle went down. Regarding the cardiac condition, however, the pain in the chest did not abate even when he was taking a rest. The antiplatelet therapy was resumed, with one type of agent given at first and then with another type added. Examinations using a coronary CT and a cadiac catheter found 90% stenosis at the proximal left anterior descending coronary artery. So, a bare metal stent was placed in the near-closed artery. Ever since, there has been no recrudescence of chest pain and no recurrence of iliopsoas muscle hematoma. The extravascated blood mass seemed to be dissolved spontaneously.
