We conducted a retrospective study to clarify the influence of anticoagulation on treatment of varicose veins using EVLA. Patients with on oral anticoagulant with those receiving no anticoagulant. Occlusion rate was 100% in both groups, and the postoperative pain and ecchymosis were minor, with no significant differences observed between the two groups. EVLA can be performed without stopping the anticoagulant medicine administration and appears to be a safe and minimally invasive treatment.

IgG4-related disease is a systemic disease, characterized by elevation of serum IgG4 and, histopathologically, massive infiltration of IgG4+ lymphocyte and plasma cell infiltration, storiform fibrosis, causing enlargement, nodules or thickening. It may affect various organs simultaneously or metachronously. Here we analyzed the clinical and pathological characteristics of 99 patients diagnosed with IgG4-related periaortitis/periarteritis and retroperitoneal fibrosis. Of 99 patients (women/men, 15/84; mean age 67.3±9.5 years), 33 were diagnosed based on the histopathological findings of perivascular/retroperitoneal lesions, 50 were diagnosed based on the characteristic imaging findings of perivascular/retroperitoneal lesions and the presence of definitive IgG4-related disease in other organ(s), and the remaining 16 patients were diagnosed by experts based on the characteristic imaging findings of perivascular/retroperitoneal legions, serological findings, response to glucocorticoid treatment, and/or the presence of suspected IgG4-related disease in other organ(s). According to the new organ-specific criteria proposed by experts, 73 (73.7%) diagnoses were categorized to be definitive, and 6 (6.1%) and 17 (17.2%) diagnoses were categorized to be probable and possible, respectively. Further analyses are needed to clarify the optimal diagnostic and therapeutic strategy of IgG4-related periaortitis/periarteritis and retroperitoneal fibrosis.

Renal artery aneurysm is rare disease. Angioplasty, kidney extraction and embolization are performed much as treatment of a renal artery aneurysm in Japan. The bench surgery consists of the three processes: kidney extraction, angioplasty of renal artery and autologous kidney transplant. It’s true that this bench surgery is complicated and operation is also limited to possible facilities, however this operation can maintain the function of the kidney, and also becomes easier of angioplasty. Bench surgery is the useful choices.

We herein report a patient who developed ipsilateral pleural effusion associated with venous hypertension of arteriovenous fistula. The patient was an 82-year-old man. An arteriovenous fistula had been created in the left forearm 10 years previously, and thereafter left brachiocephalic vein stenosis had occurred 2 years previously. Chest radiograph revealed massive left-sided pleural effusion six months before admission. The pleural effusion was diagnosed as venous hypertension with arteriovenous fistula. After performing percutaneous angioplasty on the lesion, the degree of pleural effusion tended to decrease. However, restenosis occurred in the short term, so the arteriovenous fistula had to be ligated.

We report a case of aortoduodenal fistula 6 months after uncomplicated endovascular abdominal aortic aneurysm repair. The diagnosis was confirmed by abdominal computed tomography scan. The patient was successfully treated with primary duodenal repair, removal of the infected stentgraft, in situ placement of a bifurcated graft. Aortoduodenal fistula occurred despite accurate stent graft placement without endoleak, or aortic sac size enlargement on postoperative imaging studies.
