INTRODUCTION: Arteriovenous fistulas are the best form of vascular access for haemodialysis. A radiological balloon angioplasty is the standard treatment for a clinically relevant stenosis, but the recurrence rate is high. Data on factors associated with recurrence are limited. METHODS: A single centre, retrospective analysis was performed for 124 consecutive patients who had successful interventions for dysfunctional arteriovenous fistulae, to examine factors associated with post-intervention patency...

OBJECTIVES: A major pathology affecting the usability of arteriovenous fistulas for hemodialysis is juxta-anastomosis stenosis. Intraoperative pneumatic tourniquet eliminates the use of vascular clamps, reduces vascular trauma, and may then reduce the juxta-anastomosis stenosis. The aim of this study was to compare the outcomes of arteriovenous fistula creations using the tourniquet-assisted approach versus the clamp-assisted approach. METHODS: This retrospective study analyzed the outcomes of primary arteriovenous fistulas created by the lead author from 2008 to 2017 and met the specified inclusion criteria applied to both groups...

BACKGROUND: The commonly preferred right internal jugular vein was investigated in terms of its dimensions, the relationship between its dimensions and anthropometric measures, and the outcomes of its cannulation in infants. Data regarding its position with respect to the carotid artery indicated anatomical variation. AIM: The aim of this study was to share our observations pertaining to the anatomy and position of the right internal jugular vein with respect to carotid artery using ultrasound and our experience with ultrasound-guided right internal jugular vein access in neonates and small infants...

Quality improvement initiatives should be aimed to enhance clinical outcomes, service delivery and quality of life for patients. For patients reliant on haemodialysis, vascular access is a lifeline. Survival differences relating to the type of vascular access are evident and many initiatives have focussed on increasing absolute rates of arteriovenous fistulas and/or decreasing central venous catheter use. While these have achieved some success quantitatively, the qualitative effects are less obvious. The aims of this review article are to explore the concepts of quality of care in vascular access...

INTRODUCTION: 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...

We devised a method that enables blood removal/return by creating a fistula between the skin and the great saphenous vein to insert the dialysis needle sheath in the femoral vein under ultrasonography guidance with respect to each dialysis. 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...

INTRODUCTION: Graft is an alternative to native arteriovenous fistula to ensure permanent vascular access in hemodialysis patients. The most common complication is significant stenosis, which frequently causes thrombosis and graft loss. Periodic monitoring and surveillance with elective correction of stenotic lesions can prolong graft survival. OBJECTIVE: To describe the effect of early diagnosis of significant stenosis on the rate of thrombosis and graft patency...

BACKGROUND: Increasing studies concern about idle vascular access devices, but still scant data on idle peripherally inserted central catheters. We aimed to assess the prevalence and risks of idle peripherally inserted central catheters in adult patients. METHODS: A multicenter cross-sectional observational study was performed between April 2018 and July 2018. Patient demographics and peripherally inserted central catheters-related information were abstracted using a site questionnaire by directly inquiring and medical records reviewing right after their peripherally inserted central catheters were removed...

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 prosthetic loop or a right atrial graft...

INTRODUCTION: Current guidelines recommend the placement of vascular access 6 months before the anticipated start of hemodialysis therapy; however, many patients start hemodialysis using a central venous catheter. We investigated the timing of referral for vascular access, the vascular access type at hemodialysis initiation, and the barriers to a timely referral. METHODS: The study involved a retrospective review of 237 patients for whom the first vascular access for hemodialysis was created between January and November 2017...

Peripherally inserted central catheters provide access to the central chest veins and allow administration of long-term antibiotics, chemotherapy, blood products, fluids, and parenteral nutrition. Peripherally inserted central catheters provide an essential function and are routinely placed safely, but are not without risks. This case describes an unusual complication of peripherally inserted central catheter perforation into the pericardial space with subsequent successful percutaneous removal.
