CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe evaluated the effectiveness of intravenous iloprost (IVI) in outpatients with thromboangiitis obliterans (TAO) and lower limb noninvasive transcutaneous monitoring (TCM) at follow-up (FU). Ten consecutive patients with TAO underwent IVI therapy. Transcutaneous oxygen (TcPO2) and carbon dioxide (TcPCO2) determination and laser Doppler flowmetry (LDF) were performed before and after IVI at 3, 6, and 12 months of FU. Clinical response was positive in 7 patients, whereas 3 nonresponders under- went a second IVI cycle with 1 showing a late positive clinical response. After 12 months of FU, all patients were alive without amputations. Supine and dependent TcP2 levels significantly improved (P < .005). Hallux LDF values showed significant change with the maximal hyperemic test at 44 C (P < .005). Forefoot maximal hyperemic test at 44 C LDF (P < .005) and improved venous arterial reflex (P < .05) showed statistically significant time evolution. We demonstrated some degree of IVI effectiveness and evaluated TCM in patients with TAO.

| Abstract: | We evaluated the effectiveness of intravenous iloprost (IVI) in outpatients with thromboangiitis obliterans (TAO) and lower limb noninvasive transcutaneous monitoring (TCM) at follow-up (FU). Ten consecutive patients with TAO underwent IVI therapy. Transcutaneous oxygen (TcPO2) and carbon dioxide (TcPCO2) determination and laser Doppler flowmetry (LDF) were performed before and after IVI at 3, 6, and 12 months of FU. Clinical response was positive in 7 patients, whereas 3 nonresponders under- went a second IVI cycle with 1 showing a late positive clinical response. After 12 months of FU, all patients were alive without amputations. Supine and dependent TcP2 levels significantly improved (P < .005). Hallux LDF values showed significant change with the maximal hyperemic test at 44 C (P < .005). Forefoot maximal hyperemic test at 44 C LDF (P < .005) and improved venous arterial reflex (P < .05) showed statistically significant time evolution. We demonstrated some degree of IVI effectiveness and evaluated TCM in patients with TAO. |
