Abstract
ObjectiveTo explore the safety and effectiveness of TurboHawk plaque excision system in the treatment of instent restenosis (ISR) in patients with arteriosclerotic obliterans(ASO).
MethodsTwenty eight patients with ASO who underwent the treatment of ISR by TurboHawk plaque excision system in Department of Vascular Surgery, Drum Tower Hospital Affiliated to Nanjing University Medical School became study subjects. The difference of their ankle brachial index(ABI) and Rutherford grade before revascularization and after revascularization were analyzed by rank sum test.
ResultsTwenty-eight patients all gained successful revascularization. Two adverse events happened which were tibiofibular artery embolization and perforation. Twenty-six patients were up to clinical success standard. The ABI ranged from 0.25 to 0.92 after 2 days, with a mean index of 0.66±0.17, and the difference was statistically significant compared with the ABI ranged from 0 to 0.64 before revascularization, with a mean index of 0.27±0.19(P<0.05). The Rutherford grade ranged from 1 to 4 after 2 days, with a mean grade of 2.11±0.83, and the difference was statistically significant compared with the Rutherford grade ranged from 3 to 5 before revascularization, with a mean index of 4.00±0.72(P<0.05). Twenty-six patients had vascular patency after 3 months, 1 patient underwent "thigh amputation" after 76 days because of limb necrosis and 1 patient underwent "thrombectomy" after 40 days because of femoral embolism. The ABI ranged from 0.34 to 0.90 after 3 months, with a mean index of 0.63±0.16, and the difference was statistically significant compared with the ABI before revascularization (P<0.05) and not statistically significant compared with the ABI after 2 days (P=0.11). The Rutherford grade ranged from 1 to 3 after 3 months, with a mean grade of 1.96±0.76, and the difference was statistically significant compared with the Rutherford grade before revascularization (P<0.05) and not statistically significant compared with the Rutherford grade after 2 days(P=0.53).
ConclusionsTurboHawk plaque excision system is safe and effective in the treatment of ISR in the elderly patients with ASO and can be spread. Surgeon should operate carefully and normatively to reduce the occurrence of adverse events.
