    Aims To assess the benefits of intensive statin therapy on reducing cardiovascular (CV) events in patients with type 2 diabetes complicated with hyperlipidaemia and retinopathy in a primary prevention setting in Japan. In the intension-to-treat population, intensive therapy [targeting LDL cholesterol = 2.59 to = 100 to = 2.59 to <3.10 mmol/L in patients with hypercholesterolaemia and diabetic retinopathy

    Bone marrow stem cell injection for the treatment of critical limb ischemia

    Vascular reconstruction remains a treatment of choice for critical limb ischemia. Bypass surgery has been accepted as the most effective therapy to achieve increase of blood flow and cure the ischemic symptoms. On the other hand, continuous increase of the patients suffering diabetes mellitus enhances the increase of the number of the patients with peripheral arterial disease (PAD). This tendency is also observed in Japan and expected to continue from now on. The reports of the Ministry of Health, Labor and Welfare of Japan indicated that more than 6% of population was treated for diabetes mellitus and more than 12% of population was supposed to be diabetic in 2002.1) This report also gave a warning for rapid and continuous increase of the diabetic patients at present and in the future.? As is well known, diabetes mellitus is one of the strong risk factors to cause an arteriosclerosis obliterans (ASO). Therefore, the patients with PAD will increase continuously and more severe ischemic limb will need to be treated. Moreover, diabetic macroangiopathy is characterized as showing diffuse stenosis and occlusion down to the foot arteries.2) Monckeberg’s medial calcification is also frequently observed in the ASO with diabetes mellitus.3) Therefore, along with the increase of the patients with PAD, the vascular reconstruction becomes technically demanding due to co-morbid diabetes with diffuse lesion and severe calcification. The patients, who show critical limb ischemia but are excluded from the operative candidate, are eventually performed major amputation. To prevent this disastrous sequel, therapeutic angiogenesis has been investigated.In 1996, Isner reported a new therapy to treat ischemic limb by using angiogenetic gene; vascular endothelial growth factor (VEGF).4) Since then, angiogenetic therapy started to be investigated by using gene transfer with VEGF, fibroblast growth factor (FGF)5) or hepatic growth factor (HGF).6) Animal study showed increase of the vascular network, disappearance of local coldness and recover of limb function.7,8) Human study also started by using these genes.? Major concern to use gene transfer is possible infection or carcinogenic effect via adenovirus which is used as a vector. To avoid this problem, plasmid is also used although the efficacy of transfer is less. The human application revealed that skin temperature increased, pain was cured and vascular network seemed to increase in angiography. However, the long-term effect remains undetermined

    Coil Embolisation for Endovascular Treatment of Proper Hepatic Artery Aneurysm Using the Balloon Occlusion Technique

    Introduction: Endovascular repair (ER) as a minimally invasive approach can be effective for treating hepatic artery aneurysm (HAA) with gratifying results. Microcoil embolisation is the main technique used in ER. However, the coil embolisation of a large proper HAA (PHAA) with a very wide neck tends to be extremely troublesome owing to the limited length of the inflow and outflow artery. Moreover, it is difficult because of rapid blood flow in the proper hepatic artery (PHA) and the difficulty in preserving its branch flow. Microcoil embolisation of the inflow and outflow of a PHAA with the balloon occlusion technique through an originally developed single guiding sheath system was performed successfully. Report: A 73 year old woman was diagnosed with large PHAA (65 mm) by computed tomography examination. The PHAA was successfully treated by endovascular embolisation with microcoils using the balloon occlusion technique through a single guiding sheath system. Discussion: This method is safe and effective for the treatment of a large PHAA. Keywords: Balloon occlusion technique, Endovascular repair, Hepatic artery aneurysm, Short neck patien
