AV Fistula (av + fistula)
Selected AbstractsPediatrics Access Problems in hemodialysis with a permanent central venous catheterHEMODIALYSIS INTERNATIONAL, Issue 1 2005J. Muscheites Hemodialysis is a common treatment of chronic renal failure, also in childhood. Due to the high standard of technique there are only few contraindications for this treatment at present. Limitations are given by the vessel access. But in the last years, hemodialysis has been made practicable by the permanent central venous catheter, however, with more problems. As an example for potential complications in the treatment with the permanent catheter we present an unusual case report about a twenty-one- year-old girl suffering from chronic renal failure due to reflux nephropathy, Prader-Willi- syndrome, myelonatrophia of undetermined origin with spastic diplegia of the legs, and increasing sphincter ani dysfunction. We started the renal replacement therapy when the girl was 15 years old. It was not possible to create an AV fistula due to very small vessels. Two Gore-Tex ® implants were clotted in absence of thrombophilia. Afterwards, the hemodialysis was performed by a permanent central venous catheter. The catheter had to be changed 15 times. The reasons for changing the catheter were problems of flow during hemodialysis due to clotting, dislocations, spontaneous removing of the catheter by herself, and infections. Altogether a sepsis occurred four times. The first transplantation failed due to a rupture of the transplanted kidney. A second transplantation was not possible because of the high BMI. Intermittently, the girl was treated with peritoneal dialysis (PD) in the hospital, because the PD couldn't be done at home due to different reasons. Only on weekends could the girl go home. The PD had to be finished after 6 months due to a severe psychotic syndrome. The girl died at age 21, caused by a sepsis following the 15th change of the catheter. A huge problem of frequent catheter changing is the limited availability of vessel accesses , the limits of treatment by hemodialysis.

Qureshi MBBS Abstract Background Angiosarcomas comprise less than 1% of all sarcomas, arising from endothelial cells of blood or lymph vessels. Chronic immunosuppression increases the risk of many malignancies and an association between the development of angiosarcoma with an immunosuppressed state is established. A few cases have been reported of angiosarcomas arising in the post-renal transplant patient. Specifically, there have been six cases of an angiosarcoma arising in arteriovenous (AV) fistulae in this patient population. We describe a further case and review the relevant literature with specific emphasis on a possible mechanism for the development of angiosarcoma in the post-transplant patient. Case Presentation We report the case of a 48-year-old male who developed an angiosarcoma in a ligated native AV fistula. The lesion arose on the background of immunosuppression following a successful ABO-incompatible renal transplant for chronic renal failure. Conclusion Angiosarcomas are extremely rare tumours but should be considered as a differential diagnosis for an evolving mass near the site of an AV fistula. Diagnosis relies on an index of suspicion and obtaining a definitive histological diagnosis. Both clinicians and patients should be aware that an evolving mass within or around an AV fistula should prompt urgent biopsy. J. Surg. Oncol. 2010; 101:520,523. © 2010 Wiley-Liss, Inc.

Our aim was to describe two pediatric centers' experience with the diagnosis, treatment and outcomes of children who presented with AV fistulas post-liver transplantation We report five cases of late arterio-portal fistula following liver transplantation. Four children were successfully treated with coil embolization. All of the children in this series had liver biopsies within 2,6 months of their AV fistula diagnosis. All biopsies were performed using a Bard Monopty 18 gauge needle with no ultrasound guidance and only one pass per biopsy. Two children also had PTC 4,8 months prior to their diagnosis of AV fistula. Three of the five children in this series had GI bleeds requiring banding or sclerotherapy. The other two had varices found on CT scan. All five cases in this series had ascites on their initial presentation. Four out of the five children had a history of non-compliance and the other child had a history of malabsorption and chronic diarrhea.
