Abstract:
Objective To evaluate the safety and efficacy of mechanical thrombectomy in treating in-stent restenosis of lower extremity arteriosclerosis obliterans. Methods From May 2015 to Sep 2016, the clinical data of 9 cases of lower extremity arteriosclerosis obliterans who were with in-stent restenosis(3 were stent graft)were retrospectively collected, and of which 7 were males and 2 were females with a mean age of (75.4 ± 6.3)years old. All the cases were treated by mechanical thrombectomy of Rotarex catheter. All the patients were diagnosed via low-extremity artery CTA, and treated by means of the Rotarex catheter, combined with angioplasty and stent if necessary. All patients received antiplatelet therapy. Doppler ultrasonography was taken during the followed-up. Results All the 9 cases were successed in technology, without complications in hospital. All patients received Rotarex mechanical thrombectomy. Six of which used balloon and 1 stent implanted. The ABI increased from 0.29 ± 0.07 to 0.88 ± 0.07 after treatment, the difference was statistically significant(t=28.875,P<0.05). All the patients were followed up for 3—18 (median time, 11.5)months. No death and symptoms recurrence appeared during the follow-up. Conclusions Mechanical thrombectomy using Rotarex catheter is a safe and effective treatment for in-stent restenosis in lower extremity arterial diseases.
