Metallic stent placement is safe and effective in treating peripheral venous lesions in native A-V fistula hemodialysis patients after unsatisfactory balloon dilatation.

Eleven cases of tuberculous peritonitis (TBP) in hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients at the Kaohsiung Veterans General Hospital in Kaohsiung, Taiwan between 1991 and 2000 were studied retrospectively (six cases in the HD group and five cases in the CAPD group) The diagnosis of TBP was established by either positive ascite tuberculosis (TB) culture or biopsy-proven chronic granulomatous inflammation. Fever and abdominal pain were the most common symptoms, while leukocytosis and unexplained hypercalcemia were the most common laboratory findings. Ascite analysis showed a lymphocyte predominance in all HD patients, but in only 40% of the CAPD patients. The mean duration of a diagnosis by ascite TB cultures was six weeks, while a diagnosis confirmed by laparascopic biopsy took one week. All four fatal cases were diagnosed by TB cultures. Laparoscopic biopsy provided a rapid diagnosis and resulted in low morbidity and mortality in our patients. Based on our review of all possible abstracts found in a Medline search from 1966 to 2002 using the keywords tuberculosis, peritonitis, uremia, and dialysis, this may be the first study of TBP in different dialysis patients.

IGP might be useful to evaluate procedural endpoints and predict patency outcomes in hemodialysis patients with graft outflow lesions undergoing PTA. Patients with the greater pre-PTA or post-PTA IGP, to some level, seem to have the shorter patency.
