    Notes: Abstract We herein report on a 64-year-old Japanese female patient who presented with a splenic artery aneurysm (SAA) associated with systemic lupus erythematosus (SLE). The saccular aneurysm, which measured 3 cm in diameter, was located in the proximal third of the splenic artery from the pancreas with a portosystemic shunt. A double ligation of the splenic artery (the distal and proximal sides of the aneurysm) was performed without a splenectomy. The postoperative course showed acute pancreatitis without either splenic infarction or portal thrombus. To our knowledge, the closed association of SLE with an aneurysmal dilatation of the splenic artery has not been previously reported. Both the pathogenesis and the management of SAA associated with SLE are discussed following the presentation of this case. This is the first reported case of SAA associated with SLE.

    Notes: Abstract Accurate predication of axillary node status by non-invasive diagnostic method would be of great value in cases of breast cancer. There have been few reports advocating digital subtraction angiography (DSA) as specifically advantageous for the detection of lymph node metastasis. IV (intravenous)-DSA was carried out on 42 patients with breast carcinoma using a DSA system with a matrix of 1024 × 1024×pixels. When a mass became stained in the axilla, it was considered to be metastatic. An immunohistochemical technique with JC70 antibody to platelet/endothelial cell adhesion molecules was used to evaluate the microvascular density (MVD) of the axillary lymph nodes. IV-DSA achieved a 76.2% sensitivity, 85.7% specificity, and 81.0% accuracy. The average MVD with JC70 antibody was 97.7 ± 44.4 in metastatic and 62.9 ± 23.6 in nonmetastatic nodes. MVD was significantly higher in the cancerous than in the noncancerous regions within lymph nodes. The MVD was 105 ± 38.4 in DSA-N(+) cases and was 57.8 ± 21.9 in DSA-N(−) cases, and the difference was statistically significant. In conclusion, IV-DSA is a useful diagnostic modality for detection of axillary lymph node metastasis. This new modality predicts lymph node status by assessing the neovascularization of the lymph node.
