Vascular calcification--is aldosterone a culprit?
In chronic kidney disease (CKD), increased plasma phosphate concentrations cause vascular calcification which substantially contribute to cardiovascular events and increased mortality of CKD patients. Similar to CKD patients, klotho-hypomorphic mice (kl/kl) also suffer from excessive vascular calcification leading to growth deficit, rapid ageing and early death. The hyperphosphataemia of kl/kl mice results from excessive formation of 1,25(OH)2D3 causing excessive intestinal phosphate absorption. Further, kl/kl mice further suffer from hyperaldosteronism and compelling evidence points to an active role of mineralocorticoids...

Complications and Graft Survival in Kidney Transplants With Vascular Variants: Our Experience and Literature Review
This article reports our experience in kidney transplants with vascular anomalies.Materials and methods: Between January 1996 and June 2012, 154 cadaveric kidney transplantations were performed at our center. In 35 case, vascular variants were found. Among the arterial variants we observed 27 double arteries, 2 cases with 3 arteries, and 1 case with 4 arteries. All cases of Venous variants were double veins. Based on the type of reconstructive technique used, we divided transplants into group A (n = 22) separate multiple arterial anastomoses; group B (n = 8) anastomosis on the aortic patch; group C (n = 4) single anasto...

The association of long-functioning hemodialysis vascular access with prevalence of left ventricular hypertrophy in kidney transplant recipients.
This study evaluates the impact of long-functioning hemodialysis vascular access on LVH in single center cohort of kidney transplant recipients. 162 patients at 8.7 ± 1.8 years after kidney transplantation were enrolled. Echocardiography, carotid ultrasound, and assessment of pulse wave velocity were performed. LVH was defined based on left ventricular mass (LVM) indexed for body surface area (BSA) and height(2.7). There were 67 patients with and 95 without patent vascular access. Both study groups were comparable with respect to gender, age, duration of dialysis therapy, and time after transplantation, kidney graft funct...

Vascular challenges in renal transplantation.
Conclusions The demand for renal transplants has led to more marginal-quality organs and older donors and/or recipients waiting for a second or third transplantation. Thus, the expertise of a vascular surgeon is extremely helpful in a transplantation center because it allows for marginal organ transplantation with acceptable 5-year graft survival rates.

NASA and New Organ Develop the Vascular Tissue Challenge
The news for today is that NASA's Centennial Challenges Program and the Methuselah Foundation's tissue engineering initiative New Organ have joined forces to develop the Vascular Tissue Challenge, which is currently public in a draft form as an RFI. The intent is to divide a $500,000 purse between up to three teams who can advance the state of the art in tissue engineering by reliably producing thick sections of vascularized living tissue.
I'm sure you've all seen the announcements roll in over the past few years as research groups have built small organoids that function correctly for their organ type: slivers of pancrea...

The diagnostic value of contrast-enhanced ultrasound (CEUS) as a new technique for imaging of vascular complications in renal transplants compared to standard imaging modalities.
CONCLUSIONS: CEUS is a non-nephrotoxic and safe method for the initial imaging of vascular complications in renal transplant recipients. Compared to the gold standard imaging modalities CT, DSA and radioisotope renography CEUS shows a high sensitivity and NPV in detecting vascular complications. In cases with suspected stenosis of the transplant renal artery additional DSA might be needed.

The effect of an educational program for vascular access care on nurses' knowledge at dialysis centers in Khartoum State, Sudan.
This study was to evaluate the effect of an educational program for vascular access care on nurses' knowledge at nine dialysis centers in Khartoum State. This was a Quasi experimental study (pre-and post-test for the same group). Sixty-one nurses working in these HD centers were chosen by simple random sampling method. A structured face-to-face interview questionnaire based on the Kidney Dialysis Outcome Quality Initiative (K/DOQI) clinical practice guidelines for vascular access care was used. Instrument validity was determined through content validity by a panel of experts. Reliability of the instrument was tested by a p...

Impact of Surgeon's Experience on Vascular and Haemorrhagic Complications After Kidney Transplantation.
CONCLUSIONS: The surgeon's experience is an independent risk factor for vascular and haemorrhagic complications after KTx. Acceptable post-operative vascular and haemorrhagic complications are achieved after a minimum of 26 KTx. As a donor age of >60 years and recipient CVD are also independent risk factors for vascular and haemorrhagic complications, it is suggested that these patients should preferably be operated on by surgeons who have performed more than 26 KTx operations.

Disruptive technological advances in vascular access for dialysis: an overview
AbstractEnd-stage kidney disease (ESKD), one of the most prevalent diseases in the world and with increasing incidence, is associated with significant morbidity and mortality. Current available modes of renal replacement therapy (RRT) include dialysis and renal transplantation. Though renal transplantation is the preferred and ideal mode of RRT, this modality may not be available to all patients with ESKD. Moreover, renal transplant recipients are constantly at risk of complications associated with immunosuppression and immunosuppressant use, and posttransplant lymphoproliferative disorder. Dialysis may be the only availab...

Current state of dialysis access management in Korea.
Authors: Kim YS, Kim Y, Shin SJ, Lee HS, Kim SG, Cho S, Na KR, Kim JK, Kim SJ, Kim YO, Jin DC
Abstract
The prevalence rate and the incidence rate of hemodialysis and functioning kidney transplant recipients have continuously increased; on the contrary, those of peritoneal dialysis have continuously decreased since 2006. Dialysis patients have been getting older and have been maintained on dialysis longer. Diabetic nephropathy was the leading cause of end stage renal disease. The type of hemodialysis vascular access has been stable during the last 5 years (arteriovenous fistulas 76%, arteriovenous grafts 16%, cent...

Effect of Spironolactone for One Year on Endothelial Function and Vascular Inflammation Biomarkers in Renal Transplant Recipients.
CONCLUSIONS: MR blockade did not improve biomarkers of endothelial dysfunction or vascular inflammation in renal transplant patients. Since no beneficial effect of MR blockade on vascular biomarkers was found, aldosterone is likely not a major promoter of vascular dysfunction in renal transplant patients.

Vascular Access Choice, Complications, and Outcomes in Children on Maintenance Hemodialysis: Findings From the International Pediatric Hemodialysis Network (IPHN) Registry
ConclusionsCVCs are the predominant vascular access choice in children receiving HD within the IPHN. Age-related anatomical limitations and expected early living related transplantation were associated with CVC use. CVCs were associated with poorer dialysis efficacy, higher complication rates, and more frequent need for vascular access replacement. Such findings call for a re-evaluation of pediatric CVC use and practices.

Renal transplantation using vascular conduit reconstruction in deceased kidneys with multiple renal arteries and short renal veins.
CONCLUSIONS: Vascular reconstruction using arterial and venous grafts harvested from the same deceased donor may result a helpful tool to simplify vascular anastomoses during transplantation surgery, thus avoiding their discard in advance, minimizing perioperative complications, and enabling normal graft function rates in the long-term follow-up. The successful outcome obtained by using this approach would help to expand the donor criteria for the inclusion of organs containing vascular anatomical variants.
