AB  - Background. Sodium thiosulphate (NaTS) is mostly used in haemodialysis (HD) patients with calcific uraemic arteriolopathy. This double-blind, randomized, placebo-controlled study assessed the effect of NaTS on progression of cardiovascular calcifications in HD patients. Methods. From 65 screened patients, we recruited 60 patients with an abdominal aorta Agatston calcification score >= 100. Thirty patients were randomized to receive NaTS 25 g/1.73m(2) and 30 patients to receive 100mL of 0.9% sodium chloride intravenously during the last 15 min of HD over a period of 6 months. The primary endpoint was the absolute change of the abdominal aortic calcification score. Results. The abdominal aortic calcification score and calcification volume of the abdominal aorta increased similarly in both treatment groups during the trial. As compared with the saline group, patients receiving NaTS exhibited a reduction of their iliac artery calcification score (-137 +/- 641 versus 245 +/- 755; P = 0.049), reduced pulse wave velocity (9.6 +/- 2.7 versus 11.4 +/- 3.6; P = 0.000) and a lower carotid intima-media thickness (0.77 +/- 0.1 versus 0.83 +/- 00.17; P = .033) and had better preservation of echocardiographic parameters of left ventricular hypertrophy. No patient of the NaTS group developed new cardiac valve calcifications during the trial as compared with 8 of 29 patients in the saline group. By univariate analysis, NaTS therapy was the only predictor of not developing new valvular calcifications. No adverse events possibly related to NaTS infusion were noted. Conclusions. While NaTS failed to retard abdominal aortic calcification progress, it positively affected calcification progress in iliac arteries and heart valves as well as several other cardiovascular functional parameters.

AB  - BackgroundPeripheral arterial disease (PAD) is common in patients with end-stage renal disease on hemodialysis, but is frequently underdiagnosed. The risk factors for PAD are well known within the general population, but they differ somewhat in hemodialysis patients. This study aimed to determine the prevalence of PAD and its risk factors in patients on hemodialysis.MethodsThis cross-sectional study included 156 hemodialysis patients. Comorbidities and laboratory parameters were analyzed. Following clinical examinations, the ankle-brachial index was measured in all patients. PAD was diagnosed based on the clinical findings, ankle-brachial index  lt 0.9, and PAD symptoms.ResultsPAD was present in 55 of 156 (35.3%; 95% CI, 27.7-42.8%) patients. The patients with PAD were significantly older (6710years vs. 62 +/- 11years, p=0.014), more likely to have diabetes mellitus (p=0.022), and anemia (p=0.042), and had significantly lower serum albumin (p=0.005), total cholesterol (p=0.024), and iron (p=0.004) levels, higher glucose (p=0.002) and C-reactive protein (p lt 0.001) levels, and lower dialysis adequacies (p=0.040) than the patients without PAD. Multivariate analysis showed higher C-reactive protein level (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.00-1.06; p=0.030), vascular access by Hickman catheter (OR, 4.66; 95% CI, 1.03-21.0; p=0.045), and symptoms of PAD (OR, 5.20; 95% CI, 2.60-10.4; p lt 0.001) as independent factors associated with PAD in hemodialysis patients.ConclusionThe prevalence of PAD was high among patients with end-stage renal disease on hemodialysis. Symptoms of PAD, higher C-reactive protein levels, and Hickman vascular access were independent predictors of PAD in patients on hemodialysis.

AB  - Introduction The autologous radio-cephalic arteriovenous fistula (AVF) is the best vascular access for patients on chronic hemodialysis. In some patients with inadequate blood vessels, it is necessary to create proximal AVF, or arteriovenous grafts. High percentage of primary graft failure is noted in cases where diameters of the brachial artery and the basilic vein are insufficient. The aim of this work was to introduce a new surgical technique for arteriovenous creation in patients with inadequate blood diameter. Case outline The authors have proposed implantation of brachio-basilic polytetrafluoroethylene AV forearm loop graft in two acts. In the first act, the native brachio-basilic AVF was created in the distal region of the arm by side-to-end anastomosis. Three to four weeks after the first act, significant dilatation of brachial artery and basilic vein was noted (confirmed by the use of color duplex sonography technique). During the second act, polytetrafluourethylene graft was implanted by end-to-end anastomosis on the dilated basilica vein. Conclusion AV graft that was created in two acts has sufficient blood flow without early or late complications. Primary patency was 30 months and secondary patency was 50 months. As an original method in the current literature, we recommend it in different clinical settings when there are no better alternatives for vascular access.

Visoki procenat ranog zatajivanja grafta najčešće nastaje usled malog prečnika bazilične vene ili brahijalne arterije. Cilj ovoga rada je bio da prikaže novu hiruršku tehniku za kreiranje arteriovenskog grafta kod bolesnika sa neodgovarajućim dijametrom krvnih sudova. Prikaz bolesnika Urađena je implantacija PTFE grafta u vidu petlje na podlaktici u dva akta. U prvom aktu je u distalnom delu nadlaktice kreirana brahio-bazilična latero-terminalna arteriovenska fistula pod uglom od 90 stepeni. Posle četiri nedelje, kontrolnom doplersonografijom je konstatovano znatno povećanje prečnika bazilične vene i brahijalne arterije.
