Abdominal collateral vein as an unconventional vascular access for hemodialysis in patient with central vein occlusion.

A 65-year-old female patient with chronic kidney disease stage 5 and a history of spleen neoplasm with dissemination within peritoneum is presented. During 5 years of hemodialysis therapy, bilateral occlusion of brachiocephalic and iliac vein developed as a consequence of vein catheterization. An attempt to cannulate inferior vena cava was unsuccessful. A cannulation of dilated collateral abdominal veins with dialysis needles allowed to perform several hemodialysis sessions in the patient.
