Fifteen patients with chronic obstruction of leg arteries (mean length: 6 cm) were treated with the Kensey catheter and then with PTA. In 11 cases the procedure was successful (74%) and in 2 it was interrupted--in one case for dissection and in the other for vessel perforation. Two maneuvers, after dissection, were ended with PTA and stent placement (overall success rate: 87%). Emergency surgery was never needed. In the cases solved with the Kensey catheter, the cumulative patency rate was 51% at 6, 12 and 24 months. The Kensey catheter did not improve the results of conventional PTA, which means its role is complementary to that of PTA and an alternative to more expensive laser systems, if PTA fails.

46 cases of cavernous hemangioma of the liver, studied by angiography, are reported. Part of them were studied with echotomography and CT too, and 28 with angiotomography. In author's opinion based on experience, angiographic diagnosis of the lesion is, in presence of typical angiographic patterns, always confirmed, while echotomography and CT are not specific, especially in differential diagnosis with neoplastic malignant, primitive or secondary, hepatic lesions. Diagnostic algorithm needs, in their opinion, an initial echotomographical phase and, in presence of positive pictures for expansive hepatic mass with clinical suspicion for haemangioma, angiography and angiotomography for complete and specific diagnosis.
