Use of the Amplatzer Type 2 Plug for Flow Redirection in Failing Autogenous Hemodialysis Fistulae.

Purpose: To present our experience with redirecting the outflow of mature arteriovenous fistulae (AVFs) in patients with cannulation and/or suboptimal flow problems by percutaneous intervention using the Amplatzer Vascular Plug II (AVP II).

Methods: We retrospectively reviewed patients who presented with difficulty in cannulation and/or suboptimal flow in the puncture zone of the AVF and who underwent intervention using the AVP II to redirect the outflow through a better cannulation zone from March 2009 to November 2012. The mean survival rate of all AVFs was estimated, and the effects of patient age, sex, and AVF age on the AVF survival time were determined.

Relationship of late arteriovenous fistula stenosis with soluble E-selectin and soluble EPCR in chronic hemodialysis patients with arteriovenous fistula.

Background/aims: Vascular access dysfunction caused by stenosis is a major complication for hemodialysis (HD) patients. However, physiopathology of late arteriovenous fistula (AVF) stenosis is still under investigation. The aim of the present study was to evaluate the association between plasma soluble EPCR (sEPCR) with serum soluble E-selectin (sE-selectin) concentration and late AVF stenosis in HD patients.

A rare case of intracerebral hemorrhage due to arteriovenous malformation located at petrous portion of the temporal bone.

Primary intraosseous arteriovenous malformations (AVM) are not infrequently encountered. We report a case of intraosseous arteriovenous malformation arising in the left temporal bone. A 51-year-old male patient presented with loss of conscious.

Transbrachial endoclamping of the graft for descending aortic aneurysm after the elephant trunk procedure.

Patients who have undergone the elephant trunk procedure because of aortic dissection may subsequently present with a descending aortic aneurysm. We describe the technique of "endograft aortic control by inflating a compliant aortic occlusion balloon," in which a balloon is placed in the proximal descending aortic graft without cross-clamping to avert problems of hemorrhage at the second stage of the elephant trunk procedure.

A randomized study of allopurinol on endothelial function and estimated glomular filtration rate in asymptomatic hyperuricemic subjects with normal renal function.

Background And Objectives: Endothelial dysfunction is an early manifestation of vascular injury and contributes to the development of atherosclerotic cardiovascular disease. Recent studies have implicated hyperuricemia as a risk factor for cardiovascular disease. We hypothesized that lowering uric acid in subjects with asymptomatic hyperuricemia with allopurinol might improve endothelial dysfunction, BP, estimated GFR (eGFR), and inflammatory markers.

Influence of obstructive sleep apnea on fatty liver disease: role of chronic intermittent hypoxia.

Background: Currently the common pathogenetic mechanisms in nonalcoholic fatty liver disease (NAFLD) and obstructive sleep apnea (OSA) are gaining increased attention. The aim of this study is to find out the influence of chronic intermittent hypoxemia and OSA related parameters to the severity of NAFLD.

Methods: We examined the liver functions tests and ultrasonographic data of liver as well as markers of OSA severity (apnea-hypopnea index [AHI], oxygen desaturation index, minimum oxygen saturation, percentage of time spent with S(pO(2)) < 90%) of 106 subjects.

Diagnosis and percutaneous treatment of partial subclavian steal: Doppler ultrasonography and phase contrast magnetic resonance angiography findings and a brief review of the literature.

A 66-year-old woman presented with back pain and arm claudication. Severe stenosis of the left proximal subclavian artery was detected incidentally by thorax computed tomography. Doppler ultrasonography and phase contrast magnetic resonance angiography (PCMRA) evaluation revealed partial subclavian steal.

Olmesartan associated with acute renal failure in a patient with bilateral renal artery stenosis.

In patients with renal artery stenosis (RAS), the inhibition of renin-angiotensin-aldosterone system can cause deterioration of renal function. Here we present a 75-year-old man who developed acute renal failure after olmesartan treatment. Following discontinuation of olmesartan, his renal functions normalized.

Nebivolol improves renal function in patients who underwent angioplasty due to renal artery stenosis: a pilot study.

Renal artery stenosis (RAS) is a progressive disease and may lead to chronic kidney disease by deterioration of renal functions. Endothelial dysfunction is an important causative factor for kidney damage after RAS revascularization. Nebivolol, a new generation beta blocker induces endothelium-related arterial relaxation by nitric oxide (NO) and may improve endothelial dysfunction.

Extraperitoneal pelvic myolipoma.

Myolipoma is a very rare adipocytic tumor occurring most frequently in adults, and usually is located in the retroperitoneum or abdomen. It has been described in the retroperitoneum, spinal cord, orbita, breast, round ligament, subcutaneous tissue, pericardium, rectus sheath of the abdominal wall, and abdominal cavity with attachment to the abdominal wall. Most of these tumors are discovered incidentally and are large when discovered.
