Natural Vascular Remodelling After Arteriovenous Fistula Creation in Dialysis Patients With and Without Previous Ipsilateral Vascular Access.

CONCLUSION: Arteriovenous fistulae show haemodynamic and remodelling changes up to three months post-operatively. Previous ipsilateral VAs may initiate vessel preconditioning, and accelerate the observed haemodynamic changes after AVF creation. However, this preconditioning does not result in a beneficial or detrimental effect on VA function. PMID: 31911136 [PubMed - as supplied by publisher]

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...

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: This case demonstrates that the precision banding procedure is feasible under ultrasound guidance, and the procedure is safe and effective in resolution of cardiac failure due to high flow radiocephalic fistula. PMID: 32830608 [PubMed - as supplied by publisher]

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.

Abstract Point-of-care ultrasound (POCUS) for access assessment and guided cannulation has become more common in hemodialysis units. The aims of this scoping review were to determine: circumstances in which renal nurses and technicians use POCUS; the barriers and facilitators; and evidence of the effects of POCUS in guiding assessment and cannulation. A search was conducted of CINAHL, Medline, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and ProQuest, Trove and Google Scholar as grey literature sources. Of 1904 publications, 21 studies met inclusion criteria (11 full tex...

Conclusion: In hemodialysis patients with thyroid cancer, an 131I activity approximately 30% lower than the nominal dose appears to strike an appropriate balance between absence of BM toxicity and therapeutic efficacy. To avoid overirradiation, we recommend pretherapeutic dosimetry studies for metastatic patients to calculate the amount of activity to be administered. We also recommend dosimetry monitoring during the hemodialysis sessions performed after therapeutic dose administration and under the same conditions.

Abstract Femoral venous catheterization is a common procedure in critical care patients. Pregnant women and those in the postpartum period are at risk of various complications such as shock, acute kidney injury, and thrombotic microangiopathic syndromes requiring hemodialysis and plasma exchange, which may necessitate central venous catheterization. Femoral vein catheters may also sometimes be needed. These women may have underlying pelvic congestion and varicosities. Here we present a 24-year-old female patient, who has been treated for postpartum thrombotic microangiopathy with initial clinical improvements, bec...

We report a case of high venous pressures during dialysis, secondary to an extrinsic compression of the underlying brachial artery that was diagnosed with Doppler ultrasound. The stenosis localization resembles the typical and frequent juxta-anastomotic venous outflow stenosis. This similarity can be a confounding factor and can lead to failure of conventional treatments. Careful surgical technique of arteriovenous graft creation and Doppler ultrasound mapping can prevent this entity. PMID: 32536263 [PubMed - as supplied by publisher]
