Percutaneous Endovascular Treatment of Innominate Artery Lesions: A Single-centre Experience on 77 Lesions

a and b. Successful PTA (Wanda 9 × 40mm Wanda, Boston Scientific, Natick, MA) of the innominate artery of a 75-year-old male patient with hemisymptoms and claudication of the right-upper limb. The patients claudication improved throughout the follow-up period. The last follow-up duplex scan at 14 months suggested patent innominate artery.

a and b. Successful PTA and stent (10 × 19mm Genesis, Cordis Corp, Miami, Fla) deployment in the innominate artery of a 67-year-old symptomatic female patient with upper limb claudication. Follow-up duplex scan suggested no restenosis after 57 months follow-up. a, Angiography revealed subocclusion of the innominate artery. b, Control angiography after stent implantation.

Kaplan–Meier analysis of cumulative patency rate for 77 innominate artery interventions, including excluding initial failures. Since the non-invasive direct visualisation of the innominate arteries by color duplex scan was not always possible during follow-up, we refer to “patency rate” rather than “restenosis-free patency rate” in our analysis.
