The efficacy of intraarterial (IA) and intravenous (İV) PGE1 infusions in patients with advanced peripheral arterial occlusive disease (Fontaine Stage III and IV) was investigated in our prospective open study. 4 patients had stage III and 17 had stage IV disease. Total 21 patients. 3 women and 18 men aged 24 and 78 years (mean 49) were enrolled in the study. Infusions were performed by IA route in 9 cases and by IV route in 12 cases. In alI patients, vascular recon¬struction and luminal opening operations were in'ıpossible.
The criteria for assessing were relief of rest pain, ulcer healing, reduction of analgesic consumption, pain-free walking and irıcrease of ankle-brachial doppler index (ABI). Complete response was achieved in 16 cases, partial re¬sponse was observed in 4 cases, but one 0.59±0.19 to 0.75±0.21 for rignt side and from 0.61±0.22 to 0.76±0.22 for left side (p < 0.01 respectively).
These results demonstrate that the PGE 1 treatment in patients with advanced arterial occlusive disease is clinicaly effective both by IA and by IV route.
