Abstract

Fluid removal remains a fundamental goal in the treatment of congestive heart failure (CHF). Vacuum ultrafiltration, hemodialysis, or a combination of both was used in patients with severe CHF (NYHA class IV), severe edema, and insensitivity to pharmacological treatment with diuretics. The aim of the study was to remove the overload fluid in eighteen patients, 13 men and 5 women, aged 38 to 83, with a man age of 66 years with intractable congestive heart failure. All patients were hospitalized because of severe congestive heart failure and did not respond to treatment with intravenous administration of a high dose of diuretics and positive inotropic agents. They thus underwent vacuum ultrafiltration (1 to 27 sessions) while in 4 of them hemodialysis was also performed because of high serum creatinine levels (over 4 mg/dl). Subclavian catheters were used in all patients and arteriovenous fistula was later performed in 2, because of the need for long term treatment. The average fluid removed was 2 L per session and the total fluid removed ranged from 4 to 29 L. Fourteen of the 18 patients (78%) showed significant improvement in their clinical status. Ten patients (56%) had a short term improvement but expired after 7 to 107 days of hospitalization. Four patients (22%) died after only one session of dialysis and 4 patients (22%) recovered after 8 to 23 dialysis sessions and were discharged from hospital. The majority of patients with severe chronic CHF which is intractable to conventional therapy including intravenous diuretics and inotropes improve by the use of ultrafiltration. However, a limited proportion of them survive to be discharged from the hospital.
