Vascular Access Placement Order and Outcomes in Hemodialysis Patients: A Longitudinal Study

Conclusions:HD vascular access outcomes differ based on the sequence of placement. In spite of frequent AVA placements, only half of patients effectively achieved a “permanent” vascular access and used an AVA for the majority of HD treatments.Am J Nephrol 2017;46:268-275

Central venous occlusion may occur in hemodialysis patients resulting in arm or facial swelling and failure of dialysis access. Endovascular management with balloon angioplasty or stenting has been described, but there is minimal data on the use of covered stents in this pathology. We sought to review a single institution ’s experience with the use of covered stents for central venous occlusive disease in hemodialysis patients.

Abstract This commentary critically examines key assumptions and recommendations in the 2006 Kidney Disease Outcomes Quality Initiative vascular access guidelines, and argues that several are not relevant to the contemporary United States hemodialysis population. First, the guidelines prefer arteriovenous fistulas (AVFs) over arteriovenous grafts (AVGs), on the basis of their superior secondary survival and lower frequency of interventions and infections. However, intent-to-treat analyses that incorporate the higher primary failure of AVFs, demonstrate equivalent secondary survival of both access types. Moreover, ...

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]

Conclusion: The segmented sharp recanalization is a practical strategy in treating angled long-segment CVO which is refractory to traditional guide wire transversal in hemodialysis patients.

The arteriovenous fistula (AVF) is recommended as the preferred hemodialysis access. However, placing an AVF in all patients may result in poor access outcomes and increased central venous catheter (CVC) use because of increased comorbid conditions, age, and suboptimal vessels. In patients with inadequate superficial veins for AVFs, the use of the brachial veins for creation of forearm arteriovenous grafts (AVGs) has received limited attention. This retrospective study aimed to evaluate outcomes of forearm brachial-brachial AVGs (BB-AVGs) placed in patients with poor superficial veins.

We describe two cases of end-stage renal disease patients with CIED and tunneled central venous catheter (CVC) who developed venous cava stenosis: (1) a 70-year-old man with sinus node disease and pacemaker in 2013, CVC, and a Brescia-Cimino forearm fistula in 2015; (2) a 75-year-old woman with previous ventricular arrhythmia with implanted defibrillator in 2014 and CVC in 2016. In either case, after about 1 year from CVC insertion, patients developed superior vena cava (SVC) syndrome due to stenosis diagnosed by axial computerized tomography. In case 1, the patient was not treated by angioplasty of SVC and removed CVC wit...

ConclusionsCVC remains the most frequent type of vascular access in European children commencing HD. Our results suggest that the choice for CVC is influenced by the time of referral, rapid onset of end-stage renal disease, young age, and an expected short time to transplantation. The role of vascular access type on the pattern between living and deceased donation in subsequent transplantation requires further study.

ConclusionsRepeated interventions may be necessary to maintain AVF patency and avoid central venous catheters. This is the largest series reported to date.
