Résumé
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.
Résumé
Objective To explore the security and the short term efficacy of VIABAHN stents in the treatment of branching area lesions in lower extremity arterial diseases. Methods The data of 16 patients (11 male and 5 female, aged 59.0 to 81.0 with median of 71.6) with lower extremity arterial occlusive disease from November 2014 to June 2015 were analyzed retrospectively. All lesions were located around the branching area of the lower extremity artery (3 cases in the internal iliac artery orifice, 6 cases in the deep femoral artery orifice and 7 cases in the vascular net around the knee). The short?term effects on these patients in the follow-up period, such as the success rate of surgical technique, the improvement of symptoms and the incidence of complications were summarized. Results Revascularization was technically successful in all 16 patients, and ischemic symptoms relieved significantly after the operation. The ABI were 0.36±0.12 before and 0.89±0.10 after the operation. The patients were followed up for 3 to 9 months (median 5.5 months). All the patients were achieved limb salvage and no complication occurred. Conclusions VIABAHN stent is safe and effective for the treatment of lower extremity arterial occlusive disease. The branches around the lesion can be covered with VIABAHN stents.
