1 Percutaneous Transluminal Renal Angioplasty Remarkably Improved Severe Hypertension and Renal Function in a Patient with Renal Artery Stenosis and Postrenal Kidney Failure Renal Failure, May 20, 2013
Ishida R et al. - A 69-year-old man was admitted to the authors' hospital with severe hypertension and rapidly worsening renal function. He presented with a 10-year history of chronic renal failure caused by bilateral ureteral obstruction due to retroperitoneal fibrosis. Magnetic resonance angiography and Doppler ultrasonography suggested severe right renal artery stenosis (RAS). renal angiography revealed 99% stenosis at the ostium of the right renal artery. The ...

2 A rare combination of vascular variations of both kidneys Surgical and Radiologic Anatomy, May 20, 2013
Uzmansel D et al. - Bilateral variations of renal vessels were encountered during the dissection of a 54-year-old male cadaver. There were triple renal arteries bilaterally, double renal veins on the right, and an unusual formation of renal vein on the left side. A bilateral occurrence of triple renal arteries has not been encountered in the literature, so does an incidence. Additional renal vessels have the potential to cause clinical complications such as hydronephrosis. ...

3 Case Vignettes Nephrology, May 1, 2013
Healy H et al. - Mr MF was admitted electively for non-operative correction of a known left renal artery stenosis. Previous investigations reported two small kidneys with total obstruction of the right renal artery and > 60% obstruction of the left. Recent health was compromised by multiple admissions to Coronary Care (CCU) with chest pain and acute pulmonary edema (APO) despite recent plasty of a blocked coronary graft, placed in 2002. An Interventional Radiologist accessed the ...

4 Renal artery stenosis due to fibromuscular dysplasia in a transplanted kidney from a deceased donor: A difficult diagnosis at color doppler ultrasonography Journal of Clinical Ultrasound, May 10, 2013
Venturini M et al. - The authors report the case of a 44-year-old woman, in whom serum creatinine concentration increased and arterial hypertension developed 3 months after renal transplantation. Color Doppler ultrasonography showed a low arterial resistance index and prolonged acceleration time in the interlobar arteries, and a significantly increased peak systolic velocity at the mid third of the renal artery, demonstrating hemodynamically significant stenosis. Percutaneous ...

5 Long-term follow-up of patients with atherosclerotic renal artery disease Journal of the American Society of Hypertension, February 7, 2013
Safak E et al. - The authors imaged renal arteries of 1561 hypertensive patients undergoing coronary angiography and followed this cohort for 9 years. Atherosclerotic renal artery disease appears to be a marker for the severity of atherosclerosis rather than a causative factor for atherosclerosis progression.

6 Contrast-induced acute kidney injury and clinical outcomes after intra-arterial and intravenous contrast administration: Risk comparison adjusted for patient characteristics by design American Heart Journal, April 30, 2013
Kooiman J. et al.- Direct comparisons between risk of contrast induced acute kidney injury (CI-AKI) after intra-arterial versus intravenous contrast administration are scarce.The study estimated and compared the risk of CI-AKI and its clinical course after both modes of contrast administration in patients who underwent both. The risk of CI-AKI, and its clinical course was similar after intra-arterial and intravenous contrast media administration, after ...

7 Relation of Pulse and Systolic and Mean Blood Pressure to Severe Renal Artery Stenosis in Patients Undergoing Concurrent Coronary and Renal Angiography The American Journal of Cardiology, May 16, 2013
Bazemore TC et al. - Abrupt onset of renal ischemia is associated with increased blood pressure (BP), but it is unknown whether BP remains elevated in patients with chronic severe atherosclerotic renal artery stenosis (RAS). PP, but not systolic BP, diastolic BP, mean BP, or number of antihypertensive medications, was elevated in patients with severe RAS.

8 Pulmonary Hypertension among Patients on Dialysis and Kidney Transplant Recipients Renal Failure, May 20, 2013
Abedini M et al. - Pulmonary arterial hypertension (PAH) is a serious cardiac complication among patients with end-stage renal disease (ESRD). The authors investigated pulmonary hypertension and its associated factors among patients who were on chronic dialysis and kidney transplant recipients. The results showed that pulmonary hypertension is a frequent cardiac complication among patients with ESRD, and the type of renal replacement therapy (HD), systolic and diastolic cardiac ...

9 Imaging and management of atherosclerotic renal artery stenosis Clinical Radiology, May 20, 2013
Sarkodieh JE et al. - renal artery stenosis (RAS) causes chronic, progressive ischaemic nephropathy and is the most common cause of secondary hypertension. Radiology plays a large part in the diagnosis, with a variety of imaging techniques available. Each has relative advantages and disadvantages depending on each unique clinical setting. The authors discuss and illustrate the range of diagnostic methods and interventional techniques for diagnosis and management of RAS and review the ...

10 Pulmonary Hypertension in Dialysis Patients Renal Failure, May 20, 2013
Kosmadakis G et al. - Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. The prevalence of pulmonary hypertension in dialysis patients is relatively high and varies in different studies from 17% to 49.53% depending on the mode of dialysis and other selection factors, such as the presence of other cardiovascular comorbidities. The non-specific therapeutic options that proved to be beneficial in ...
