[Four Times Aortic Valve Replacement for Recurrent Aortic Annulus Destruction Due to Behçet's Disease:Report of a Case].

Surgical results of aortic regurgitation with Behcet's aortitis is associated with high morbidity and mortality due to risk of annular dehiscence. Here we describe a case of severe aortic regurgitation with Behcet's disease in 51-year-old man who underwent aortic valve replacement and subannular patch reconstruction for suspected infectious endocarditis with severe aortic regurgitation and subannular abcess. Then we performed three times aortic valve replacement for recurrent prosthetic valve dehiscence.

Hybrid treatment of a giant coronary artery aneurysm in a patient with immunoglobulin G4-related disease.

A 62-year-old man was diagnosed with a giant coronary artery aneurysm associated with immunoglobulin G4 (IgG4)-related disease. He had previously undergone two thoracic operations with sternotomies and abdominal aortic aneurysm repair for IgG4-related aortopathy. We opted for hybrid open and endovascular repair to reduce risk and avoid complications of a resternotomy and extracorporeal circulation.

Post-myocardial infarction left ventricular septal dissecting aneurysm: a case report.

Background: Post-infarction perforation of the ventricular septum is recognized as a major complication of post-myocardial infarction. However, post-infarction ventricle dissection is seldom reported, as the ventricular shunt often accompanying this condition is a significant cause of cardiogenic shock. We encountered a rare case of ventricular dissection unaccompanied by a shunt, which caused a state of shock.

Lumbar artery aneurysm complicated by a fistula between the aneurysm and the duodenum in a patient with Leriche syndrome: A case report.

Introduction: Various collateral pathways maintain blood flow to the lower extremities in patients with Leriche syndrome. The occurrence of true aneurysms in the lumbar artery-a component of an extensive collateral circulation network in patients with Leriche syndrome-is extremely rare.

Presentation Of Case: A 73-year-old man with Leriche syndrome was diagnosed with lumbar artery aneurysm complicated by a duodenal fistula.

Fistula between the Thoracic Duct and an Unusual Vessel Aneurysm Branching Off the Abdominal Aorta Revealed by Aneurysm Rupture: A Case Report.

Fistulas between an aneurysm branching off the abdominal aorta and the thoracic duct are rare. We report a case of aneurysmal-thoracic duct fistula diagnosed by angiography when aneurysm ruptured, and we successfully treated by catheter embolization. A 42-year-old man was referred to our hospital with a chief complaint of sudden back and chest pain.

A case series of favorable vessel dilatation using a nitinol scoring element-equipped helical balloon catheter (AngioSculpt®).

Objective: Although percutaneous transluminal angioplasty is an effective therapy against vascular access failure in hemodialysis patients, recurrent stenosis imposes enormous burden for hemodialysis patients. A nitinol scoring element-equipped helical balloon catheter (AngioSculpt) has been altered the landscape for treating several vascular diseases. It is not, however, fully elucidated whether AngioSculpt for advanced vascular access stenosis, difficult to expand by conventional balloons, successfully provides bailout angioplasty.

Predictors of patent false lumen of the aortic arch after hemiarch replacement.

Background: Hemiarch replacement for acute type A aortic dissection is less invasive than total arch replacement but involves increased risk of late aortic arch dilation because of patent false lumen of the aortic arch. If we can predict this risk, it may be a valuable prognostic indicator for selecting surgical procedures for acute type A aortic dissection.

Methods: We reviewed our surgical experience to predict patent false lumen.

The prognosis of patients on hemodialysis with foot lesions.

Objective: Many studies have shown the high prevalence and incidence of peripheral arterial disease and the marked morbidity and mortality associated with peripheral arterial disease in hemodialysis patients. The purpose of this retrospective study was to clarify the probability of survival and limb salvage in patients with foot lesions and how to manage these patients.

Methods: Data were collected in a retrospectively maintained database for 319 lower limbs with foot lesions in 234 hemodialysis patients treated in a university hospital between 1980 and 2011.

Remodeling of proximal neck angulation after endovascular aneurysm repair.

Objective: This study investigated the remodeling of proximal neck (PN) angulations of abdominal aortic aneurysms (AAAs) after endovascular aneurysm repair (EVAR).

Methods: A 64-row multidetector computed tomography scan of AAAs treated with EVAR was reviewed, and the PN angulation was measured on a volume-rendered three-dimensional image. The computed tomography scan was examined preoperatively, after EVAR at 1 week, 1 month, 6 months, 1 year, 1.

Partial debranching hybrid stent graft for distal aortic arch aneurysms.

Purpose: To evaluate the early outcomes of treating distal aortic arch aneurysms (DAAAs) with a partial debranching hybrid stent graft, and to analyze the morphology of distances among the supra-aortic branches.

Methods: We used this stent graft to treat DAAA in 12 patients, by debranching the left common carotid artery (LCCA) and the left subclavian artery (LSA). With computed tomography (CT) data on the collective total 28 thoracic aortic aneurysms, the distances from the LSA to the LCCA and those from the LSA to the brachiocephalic artery (BA) were measured using multiplanar reconstruction (MPR) and centerline of flow (CLF) methods.

Huge hemangioma in the chest mimicking a breast tumor: report of a case.

A 35 year-old man first noticed an elastic mass like breast tumor in his left chest 17 years ago. It enlarged to the size of a child's head. Computed tomography showed a well-circumscribed mass in the left chest.

Stent strut penetration during thoracic endovascular aortic repair: report of a case.

A case of persistent sciatic artery aneurysm accompanied by a persistent sciatic vein.

A persistent sciatic artery is a rare anomaly. On the other hand, a persistent sciatic vein is frequently associated with Klippel-Trenaunay syndrome. In a 71-year-old female with a complete-type persistent sciatic artery aneurysm, we performed aneurysmectomy and right femoropopliteal bypass surgery.

Transcutaneous carbon dioxide tension for the evaluation of limb ischemia.

Purpose: Understanding the hemodynamics of critical limb ischemia caused by chronic peripheral arterial occlusive disease is important to evaluate its severity and the efficacy of treatment. We investigated the usefulness of transcutaneous carbon dioxide tension (tcPCO(2)) measurement for evaluating ischemic limbs, in conjunction with the measurement of ankle pressure (AP), toe pressure (TP), skin perfusion pressure (SPP), and transcutaneous oxygen tension (tcPO(2)).

Methods: We measured tcPCO(2) in the dorsum of the foot in 158 patients (304 limbs) with arteriosclerosis obliterans.

Results: Among a total 628 patients seen, 306 were in their 70s (group A) and 108 were in their 80s or older (group B).

Inhibition of autophagy prevents hippocampal pyramidal neuron death after hypoxic-ischemic injury.

Neonatal hypoxic/ischemic (H/I) brain injury causes neurological impairment, including cognitive and motor dysfunction as well as seizures. However, the molecular mechanisms regulating neuron death after H/I injury are poorly defined and remain controversial. Here we show that Atg7, a gene essential for autophagy induction, is a critical mediator of H/I-induced neuron death.

The Clinical Course of Buerger's Disease.

The clinical and social characteristics of 118 patients with Buerger's disease (thromboangiitis obliterans: TAO) were surveyed. The prognosis for many patients is relatively favorable. Arterial reconstruction plays a role in shortening the healing times of ischemic ulcers despite its poor long-term results.
