The real-world data of lipid-lowering treatment in patients with peripheral artery disease and its association with severity of disease.

Background: The risk of coronary artery disease in peripheral arterial disease (PAD) is high, life prognosis is poor, and lipid-lowering treatment with statins has been reported to improve prognosis. In clinical practice, however, hypolipidemia is more common in patients with severe PAD and statin prescription rates appear to be low, but specific data are scarce in Japan. Therefore, we conducted this cross-sectional study in collaboration with other centers of vascular surgery to determine the rate of statin prescriptions for PAD patients in real-world practice, the rate of achievement of low-density lipoprotein (LDL) cholesterol control targets, and whether statin non-use is a determinant factor of critical limb ischemia (CLI).

Prosthesis use and the change in activities of daily living following below-knee amputation in patients undergoing hemodialysis.

Introduction: Patients undergoing hemodialysis are at an increased risk of peripheral arterial disease, amputation of lower extremities, and decline of activities of daily living. Although a prosthesis is used to support activities of daily living, no previous study reported the association of prosthesis use with the change in activities of daily living following leg amputation in hemodialysis patients. The purpose of this study was to compare the changes in activities of daily living following amputation between those who created a prosthesis and those who did not.

Transmission dynamics of a linear vanA-plasmid during a nosocomial multiclonal outbreak of vancomycin-resistant enterococci in a non-endemic area, Japan.

The spread of vancomycin-resistant enterococci (VRE) is a major threat in nosocomial settings. A large-scale multiclonal VRE outbreak has rarely been reported in Japan due to low VRE prevalence. We evaluated the transmission of vancomycin resistance in a multiclonal VRE outbreak, conducted biological and genomic analyses of VRE isolates, and assessed the implemented infection control measures.

Long-Term Results of Crossover Bypass for Iliac Atherosclerotic Lesions in the Era of Endovascular Treatment: The Re-ACTION Study (trospective ssessment of rossover Bypass as a reatment for liac Lesis).

The aim of this study was to elucidate the long-term results of crossover bypass (CB) for iliac atherosclerotic lesions in the era of endovascular treatment (EVT). A retrospective multicenter cohort study was performed. CB was performed in 242 patients between 2003 and 2014 by vascular surgeons at multiple medical centers in Japan.

Right heart failure caused by direct pressure of distal arch aneurysm.

We report a rare case of right heart failure caused by distal aortic aneurysm. Although aortopulmonary fistula is a common complication of giant aortic arch aneurysm, right heart failure caused by mechanical pressure by aneurysm is very rare. A 79-year-old female patient presented dyspnea.

[Thoracic Endovascular Aortic Repair Via Internal Iliac Artery Conduit].

A 77-year-old man with a history of stent implantation in the right common iliac artery(CIA) and the left external iliac artery(EIA) was admitted to our hospital for a rapid growth of an aneurysm( max 53 mm) at Th11 level of the descending aorta. Although thoracic endovascular aortic repair (TEVAR) was required, there were many problems about access rout. The infrarenal abdominal aorta and the left EIA were severely calcified, and the lumens of the right CIA stent(5.

[Cor Triatriatum Diagnosed in Adulthood;Report of a Case].

A 64-years-old man had cor triatriatum (Lucas-Schmidt type I A) with severe mitral regurgitation and atrial fibrillation. We perfomed resection of the anomalous septum between the accessory chamber and left atrium, and conducted mitral annuloplasty and maze procedure. Arrhythmia were not encountered after surgery.

[Two-staged Hybrid Repair for Extensive Aortic Aneurysm;Report of a Case].

A 74-year-old woman progressed to extensive aortic aneurysm after 2 years and 6 months from onset of type B dissection. A computed tomography scan revealed aortic aneurysm from ascending aorta to Th12 level of descending aorta. Her appearance was very frailty.

[Extended total arch replacement with coronary artery bypass grafting( CABG) via left thoracotomy;report of a case].

The operative procedure of extensive aortic aneurysm with ischemic coronary artery disease is controversial. We report a case of arch and descending thoracic aortic aneurysm replacement with coronary artery bypass grafting(CABG)via left thoracotomy. A 70-year-old man followed up by hepatic disease was diagnosed with expanding aortic thoracic aneurysm at the other hospital.

Surgical experience for the pulmonary artery sarcoma.

Background: Pulmonary sarcoma arising from the pulmonary artery is a rare disease and its prognosis is disastrous.

Methods: Five patients who underwent surgery for pulmonary artery sarcoma were reviewed.

Results: All patients except one were initially diagnosed with pulmonary embolism.

Right ventricular outflow tract reconstruction for primary pulmonary artery sarcoma.

Primary pulmonary artery sarcoma is extremely rare and a lethal tumor. Complete resection of the tumor and following adequate reconstruction is the only hope for cure and prolonged survival. We report a case of successful surgical excision of primary pulmonary artery sarcoma involving pulmonary trunk, pulmonary valve and right ventricular outflow tract wall, which were replaced with prosthetic valved conduit.
