Outcomes following peritoneal dialysis catheter removal with reinsertion or permanent transfer to haemodialysis.
CONCLUSION: Patient survival was comparable between patients who re-attempted peritoneal dialysis and patients who transferred to haemodialysis. Patients who had previous catheter removal due to infections had favourable technique survival than those due to catheter malfunction.

Dialysis therapy: Its past, present, and future? My personal recollection of dialysis therapy.
Authors: Ohira S, Kukita K Abstract In Dr Ohira's era, hemodialysis was done using an external arteriovenous shunt. External arteriovenous shunts surely made repeated hemodialysis possible, but they also brought about serious complications which necessarily produced the arteriovenous fistula. Arteriovenous fistula is definitely the most important contribution to long-term survival of the hemodialysis patient. Hemodialysis therapy soon became very common, so that various kinds of patients appeared for it. Then came the era of arteriovenous grafts, because many patients lost good vessels in order to create the arteri...

Current status of vascular access in Japan-from Dialysis Access Symposium 2017.
Authors: Fukasawa M Abstract At the second Dialysis Access Symposium held in Nagoya, Japan, a proposal was made to investigate the differences in vascular access methods used in different countries. In this article, we describe the management of vascular access in Japan. The Japanese population is rapidly aging, and the proportion of elderly patients on dialysis is also increasing. There were 325,000 dialysis patients in Japan at the end of 2015, of whom 65.1% were aged 65 years or above. The number of patients with diabetic nephropathy or nephrosclerosis as the underlying condition is also increasing, where...

A new access, Dermatorrhea, 10 samples of the great saphenous vein.
We report the principles, methods, and cases. A skin-great saphenous vein fistula is created under local anesthesia. It is used for blood removal/return during maintenance hemodialysis performed immediately after creating the fistula. Ten limbs of 10 patients (three men and seven women; mean age, 77.6 ± 4.8 years; dialysis history, 9.9 ± 13.0 years), where skin-great saphenous vein fistulas were created in our hospital between May 2017 and June 2018, were included. In all the cases, an arteriovenous fistula or arteriovenous graft was difficult to create because of the...

Forearm loop arteriovenous grafts preserve and may create new upper arm access sites.
This study evaluated the mid-term patency of forearm loop arteriovenous grafts and the dilation of previously inadequate upper arm basilic and cephalic veins after failed forearm loop arteriovenous graft. METHODS: All access procedures from September 2009 to December 2015 were reviewed. Vein mapping measurements were used to determine whether there was "adequate" upper arm cephalic and/or basilic vein, defined as ⩾3 mm by duplex ultrasound, at the time of forearm loop arteriovenous graft creation. Outcomes of forearm loop arteriovenous graft were compared with upper arm arteriovenous fistula, and pri...

Options for end stage vascular access: Translumbar catheter, arterial-arterial access or right atrial graft?
Authors: Inston N, Khawaja A, Mistry H, Jones R, Valenti D Abstract BACKGROUND: Running out of vascular access for dialysis is thankfully rare, but despite this, most units will have a number of patients with few options and in a precarious state. The increasing longevity of dialysis patients portends more patients will reach minimal access options. End stage vascular access is poorly defined but classification may enable assessment and comparison of treatment options. Three options for patients with end stage access are a central venous catheter through a translumbar or transhepatic route, arterial-arterial prosth...

Timing of referral for vascular access for hemodialysis: Analysis of the current status and the barriers to timely referral.
CONCLUSION: Only 23% of patients were referred for vascular access 6 months before the anticipated hemodialysis therapy. In addition, 53% of patients initiated hemodialysis with a central venous catheter. Avoidance of catheter insertion was mostly successful in patients referred 2 months before hemodialysis initiation. The most common modifiable barrier to the timely referral was noncompliance. PMID: 30958094 [PubMed - as supplied by publisher] (Source: The Journal of Vascular Access)

Current state of dialysis treatment and vascular access management in Japan.
Authors: Sato T, Sakurai H, Okubo K, Kusuta R, Onogi T, Tsuboi M Abstract According to the data from the Japanese Society for Dialysis Therapy, the number of dialysis patients was about 330,000 at the end of 2016. The mean age of newly initiated patients was 69.4 years and that of maintenance was 68.2 years. And, diabetic nephropathy is the most common primary disease, with an incidence rate of 43.2%. These results mean that the systemic vascular condition is getting worse. In spite of these backgrounds, the patients of 97.3% were treated by hemodialysis; therefore, careful management of vascular acce...

These patients frequently have renal dysfunction and many reach end-stage renal failure. If haemodialysis is required, minimization of infection risk is essential. Arteriovenous grafts have been recommended for these patients due to hypothetical concerns regarding fistula maturation due to continuous flow.
