A 17-year-old man received continuous ambulatory peritoneal dialysis (CAPD) catheter implantation and had started peritoneal dialysis. Perfusion failure of peritoneal dialysis catheter occurred one month after the catheter implantation. Transcatheter contrast examination revealed catheter obstruction about 4-5 cm from the catheter tip.

Plasma Exchange Is Highly Effective for Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis Patients With Rapidly Progressive Glomerulonephritis Who Have Advanced to Dialysis Dependence: A Single-Center Case Series.

Plasma exchange (PEX) can be an effective treatment in anti-neutrophil cytoplasmic antibody-associated vasculitis with severe renal damage; however, it is still controversial. Among cases of newly diagnosed AAV with rapidly progressive glomerulonephritis at our department from 2008 onward, 11 patients who received PEX (seven cases for severe renal damage [R-PEX] and four cases for lung hemorrhage [L-PEX]) were retrospectively analyzed. All cases of R-PEX were dependent on hemodialysis at the beginning of PEX and all received seven sessions of PEX (50 mL/kg or 1.
