BACKGROUND: Iloprost, a prostaglandin I2, is chemically stable and it has been successfully used by intravenous infusion in severe limb ischemia. Usually Iloprost is diluted in 0.9% sodium chloride solution and infused intravenously for six hours each day for 28 days in hospital. METHODS: In the present study after the first three days of infusion with a traditional pump in hospital, a home pump has been utilised for the infusion of Iloprost at home. This device allows the continue infusion of Iloprost at a flow rate of 2 ml/h for six days, then the pump is filled with a new solution. The home pump consists of a protective shell in polycarbonate (10 x 12 cm), 270 ml of volume, inside there is a balloon reservoir (3 membranes) which is filled with Iloprost. The structure of Iloprost does not change into the home pump as evidenced by HPLC studies and its continue infusion allows plasmatic high levels of its active isomers during the 28 days of therapy. In 30 patients, 25 men and 5 women (mean age 61 years) with Fontaine stage IIB (6), III (5) and IV (19) POAD Iloprost has been infused with the home pump. The follow-up period was 1 to 16 months. RESULTS: The results have shown 4 major amputations and 1 death, in 9 patients complete pain relief and ulcer healing, and in 6 patients only improvement in relief of rest pain and ulcers. CONCLUSIONS: All the patients appreciated this system of infusion because they had a normal life; in addition it is less expensive because the patients stay in hospital only 3 days.

Abstract
BACKGROUND: Iloprost, a prostaglandin I2, is chemically stable and it has been successfully used by intravenous infusion in severe limb ischemia. Usually Iloprost is diluted in 0.9% sodium chloride solution and infused intravenously for six hours each day for 28 days in hospital. METHODS: In the present study after the first three days of infusion with a traditional pump in hospital, a home pump has been utilised for the infusion of Iloprost at home. This device allows the continue infusion of Iloprost at a flow rate of 2 ml/h for six days, then the pump is filled with a new solution. The home pump consists of a protective shell in polycarbonate (10 x 12 cm), 270 ml of volume, inside there is a balloon reservoir (3 membranes) which is filled with Iloprost. The structure of Iloprost does not change into the home pump as evidenced by HPLC studies and its continue infusion allows plasmatic high levels of its active isomers during the 28 days of therapy.
