This paper investigated the effects of continuous vena-venous hemofiltration on inferior vena cava reconstruction.

Totally, 11 patients were observed, vascular access in right internal jugular vein and femoral vein catheterization was established guided by ultrasound, and heparin-free continuous vena-venous hemofiltration was used to substitute for extracorporeal veno-venous bypass. Furthermore, blood pressure, central venous pressure, urine volume, blood platelet, serum albumin, renal function, serum cystatin C, CRP, TBil, AST, ALT, serum amylase, serum lipase, PLT, PT, APTT, Fig, D-mier, and adverse events were determined.

All operations were completed successfully. Average time of continuous vena-venous hemofiltration was 2.96 ± 0.76 h. No hematoma and blood leakage was occurred when catheters were inserted, and no luminal stenosis and catheter-related infections were observed. Visceral congestion was observed when the inferior vena cava was clamped, but significantly improved immediately after the continuous vena-venous hemofiltration was begun. No hemofilter was changed due to clotting during continuous vena-venous hemofiltration therapy. Blood pressure, central venous pressure, and urine volume of the patients maintained stable. No significant change was observed in blood platelet, serum albumin, and serum creatinin. Serum cystatin and hsCRP increased after operation, but still in normal level.

Heparin-free continuous vena-venous hemofiltration was an effective mode as veno-venous bypass in the treatment of inferior vena cava interruption and reconstruction.
