Outcomes of post-operative duplex ultrasound following arteriovenous fistula formation: A pragmatic single-centre experience.

This study aims to determine whether post-operative duplex ultrasound surveillance can improve fistula patency at 12 months and improve the proportion of 'pre-haemodialysis' patients commencing haemodialysis via a usable fistula. METHODS: All arteriovenous fistulae formed between 1st January 2015 and 31st August 2017 in a single, tertiary vascular centre were included. Primary and secondary patency at 12 months, along with the proportion of pre-haemodialysis patients commencing haemodialysis via a usable arteriovenous fistula, were compared between the fistulae undergoing duplex ultrasound surveillance and 'standard practice'. RESULTS: Two hundred forty-one arteriovenous fistulae were created in 216 patients. A higher proportion of brachiobasilic transposition arteriovenous fistula and patients undergoing arteriovenous fistula creation following a previously failed access were identified in the duplex ultrasound surveillance group. Primary patency at 12 months (hazard ratio = 0.43, 95% confidence interval = 0.30-0.61, p

Authors: Gołębiowski T, Konieczny A, Letachowicz K, Krajewska M, Kusztal M Abstract Central venous catheter (CVC) for hemodialysis are frequently implanted to the internal jugular vein. Thyroid cysts are commonly shown in ultrasound examination and their recognition should not pose a problem. Herby we present an uncommon case of the thyroid cyst unintended puncture, during an attempt of CVC insertion. No further clinical consequences were observed. For all practitioners, involved in interventional nephrology, such complication may be of the utmost importance. PMID: 32985345 [PubMed - as supplied by publisher]

We report a case of 69-year-old woman. In history, type II diabetes mellitus and arterial hypertension admitted to our hospital for the evaluation of leg pain, asthenia, diarrhea, and malaise. She was in the treatment with metformin and ARB. Laboratory data revealed renal failure: serum creatinine (Scr 16.5  mg/dl, BUN 280 mg/dl) hyperkalemia and severe anemia (Hb 7.8 g/dl). Renal ultrasound displayed preserved kidneys size. An X-ray of backbone showed fracture. She underwent hemodialysis in urgency regimen. After some days, urine output began to improve up to 1200 cc/24 h. we find proteinuria in n...

Authors: Zhang L, Zhan S, Wang Y, Xiao G, Liu W Abstract BACKGROUND: Endovascular treatment of acute thrombosed arteriovenous grafts performed completely under ultrasound guidance has rarely been reported. We compared the efficacy of a new endovascular thrombectomy technique (percutaneous manual thromboaspiration through the introducer sheath) with classical hybrid thrombectomy (minimally invasive surgical thrombectomy combined with highpressure angioplasty) performed completely under ultrasound guidance, for arteriovenous graft thrombosis. METHODS: This was a retrospective cohort study involving patients recei...

AbstractTo investigate the usefulness of ultrasound-guided (USG) intraluminal approach for femoropopliteal (FP) lesion. 64 patients (73 limbs) with de novo long occlusive (>  15 cm) FP lesions underwent USG intralumial approach from April 2012 to October 2016. Periprocedural intravascular ultrasound findings were collected. Clinical outcome and predictors of restenosis after USG intraluminal approach for de novo long occlusive FP lesion were investigated. Among the s tudy participants, 34% were female, 50% had diabetes mellitus, and 10% received hemodialysis. Lesion and chronic total occlusion (CTO) lengths ...

acute;zsi L, Rosivall L Abstract INTRODUCTION: The implantation of acute or chronic vascular accesses for hemodialysis (HD) in end-stage kidney disease patients is a critical skill procedure for nephrologists, with an impact on short- and long-term outcomes of the modality and patient survival. Placement circumstances, however, may depend on the availability of technological support and will likely vary across the world. MATERIALS AND METHODS: We retrospectively reviewed our local experience with ultrasound-guided tunneled dialysis catheter (TDC) insertions but without access to fluoroscopic guidance. Data we...

CONCLUSION: Initial technical success rate of percutaneous arteriovenous fistulas placement was comparable to published studies. Early and aggressive secondary angiographic interventions of arteriovenous fistulas failing to meet cannulation requirements, improved coordination of post-operative care, and outpatient dialysis center education appear to be the primary targets for quality improvement.

Arteriovenous fistulas (AVF) remains the preferred method of vascular access for hemodialysis due to favorable patency rates, low infection rates, and fewer complications.1 In order for an AVF to be used, it requires adequate maturation and should be easily cannulated. In addition to affecting maturation, excess adipose tissue overlying the vessels in obese patients often makes the AVF too deep to cannulate for hemodialysis and can necessitate more extensive procedures in order to access the vessels.
