Chronic atherosclerotic occlusion of the abdominal aorta is a rare disease in clinical practice. In this disease, juxtarenal aortic occlusion is defined as the condition extended, adjacent to the renal arteries. The treatment of juxtarenal aortic occlusion is more difficult than a 'simple' abdominal aortic occlusion. Vascular surgery of a juxtarenal aortic occlusion-specifically aortic endarterectomy and bypass grafting-is a challenging procedure that almost invariably requires aortic cross-clamping above the level of the renal arteries, and may be associated with significant morbidity and mortality. With the advent of endovascular treatment, percutaneous transluminal angioplasty and stent implantation have been used increasingly as an alternative to conventional surgery in the management of patients with aortoiliac disease. However, endovascular treatment for juxtarenal aortic occlusion is not common and, also, special attention is needed with regard to possible renal complications. Here, we report the successful revascularization of a case of chronic juxtarenal aortic occlusion with endovascular treatment and adjunctive anticoagulation.

Anomalous origin of a coronary artery is rare and does not generally lead to myocardial infarction and paroxysmal supraventricular tachycardia (PSVT). We report an uncommon case of anomalous origin of the right coronary artery (RCA) originating from the left sinus of Valsalva with PSVT and myocardial ischemia. A 58-year-old man presented with PSVT. After arrhythmia subsided, electrocardiogram showed ST and T wave abnormalities, and transient cardiac enzymes were found to be elevated. Coronary CT angiography confirmed that there was anomalous origin of the RCA originating from the left sinus of Valsalva and no intracoronary stenotic lesion. He was managed with conservative treatment, having no symptoms on clinical follow-up for 4 years.

Colonic lipoma, a very rare form of benign tumor, is typically detected incidentally in asymptomatic patients. The size of lipoma is reported variously from 2 mm to 30 cm, with higher likelihood of symptoms as the size is bigger. Cases with symptom or bigger lesion are surgically resected in principle; endoscopic resection, which has developed recently with groundbreaking advance of endoscopic excision technology, is being used more often but with rare report of success due to high chance of complications such as bowel perforation or bleeding. The authors report here, together with a literature review, our experiences of three cases of giant colonic lipomas showing complete remission after aggressive unroofing technique, at certain intervals, using snare catheter at the origin of the lipoma so that the remaining lipoma could be drained out of the exposed surface spontaneously, in order to reduce complications.

Hematopoietic cell transplantation recipients have a high risk of subsequent malignant neoplasms. Among post-transplantation lymphoproliferative disorders (PTLDs) after hematopoietic cell transplantation, Hodgkin's lymphoma is rare and distinct from the majority of other PTLDs because of its later onset and relatively good prognosis. It is known to be associated with exposure to the Epstein-Barr virus, and the mixed cellularity subtype is the most common. We herein describe two cases of Hodgkin's lymphoma that developed after allogeneic hematopoietic cell transplantation.

Renal artery pseudoaneurysm is an uncommon disease. A 47-year-old man complained of recently developed gross hematuria and left flank pain. The initial laboratory study and radiographic evaluation revealed acute pyelonephritis. After the treatment with antibiotics, gross hematuria was resolved and the patient was discharged. However, he revisited with repeated gross hematuria and throbbing left flank pain. The renal angiography revealed left intra-renal arterial pseudoaneurysm. Angiographic embolization by glue injection was successfully performed. Thereafter, gross hematuria and flank pain were disappeared. We report a successful glue embolization of intra-renal artery pseudoaneurym associated with acute pyelonephritis.
