BACKGROUND: Insufficient venous vasculature disallows autologous arteriovenous fistula creation. In this case an arteriovenous conduit of expanded polytetrafluoroethylene (ePTFE) interponed between artery and vein is used for hemodialysis. Although arteriovenous graft infection is an infrequent complication, infected grafts cannot be used for hemodialysis and can cause infection, sepsis and bleeding. Treatment options remain limited but the general approach is to maintain functional angioaccess and to eradicate infection. AIM: To summarize current knowledge of the prevention and treatment of arteriovenous graft infection. METHODS: Literature review. CONCLUSIONS: ePTFE graft present an unreplaceable material used for angioaccess in patients with an insufficient venous vasculature. A number of risk factors causing graft infection is known. Since hemodialysis patients are a high-risk group, an effective strategies for graft infection prevention and early diagnosis should be determined. Among the most important risk factors belong surgical procedure, recurrent venipuncture and other infection disease. The prostheses should be removed when infected, especially in the presence of sepsis. In case of "localized infection", the prostheses can be removed partially only under the condition of careful patient selection and subsequent follow-up.
Aims. To provide the first single-center study of a Czech renal transplant program that compares skin cancer risk estimates to the general population. Methods. We studied a total of 603 patients undergoing renal transplantation at the University Hospital Olomouc Transplant Center between January 1984 and December 2009. The mean time of follow-up was 5.5 years. Three patients were excluded for skin cancer diagnosis before transplant. The cohort was linked with the National Cancer Registry of the Czech Republic. For non-melanoma skin cancer (NMSC), the observed number of cancers were compared to the expected numbers of NMSC based on national cancer incidence rates stratified by age. The standartized incidence ratio (SIR) was calculated as observed-to-expected ratios. Results. We found a total of 127 cases of skin cancers in 55 patients. 52/55 (94.5%) were patients with non-melanoma skin cancers, 2/55 (3.6%) patients had malignant melanoma, and we uncovered one case of merkel cell carcinoma of the skin (1.8%). There were no cases of Kaposi‘s sarcoma, cutaneous lymphoma or malignant fibrous histiocytoma. For NMSC, the overall SIR was 7.39 (95% confidence interval 5.52–9.70). Thus, skin cancer was the most common malignant condition, representing 64.1% of all malignant tumours detected in study population. Conclusion. We confirmed that skin cancer is a major complication in renal transplant recipients. Therefore it is important to increase the intensity of surveillence for these lesions in transplant patients.

BACKGROUND: The autogenous brachiocephalic or brachiobasilic arteriovenous elbow fistula is not considered to be only the secondary haemodialysis access. In patients with an unsuitable forearm vessel bundle, it is indicated as primary access and it is the method preferred to the fistula creation using a vascular prosthesis. Its rather rare complication is the development of upper extremity ischemia. AIM: To summarise current knowledge of this fistula type and its associated complications METHODS: Review of the literature. RESULTS: The creation and maturation of the fistula and occurrence of the steal syndrome is influenced by a number of factors. The analysis and awareness of such factors will provide for creation of a suitable fistula as well as for timely complication diagnostics and treatment. CONCLUSIONS: The autogenous elbow fistula utilising the brachial artery and the cephalic or basilic vein in the upper extremity represents a high-quality haemodialysis access. Its potential complication is the occurrence of the steal syndrome. Its occurrence and manifestations do not constitute indications for ligation of the access. The gathered information shows that a suitable surgical procedure can help meet the basic rule for haemodialysis access--resolving the ischemia and maintaining the access.
