In Stent Restenosis

In-stent restenosis is complex, difficult to treat and has led to a ‘leave less metal behind’ approach to femoropopliteal intervention. Postangioplasty dissection often requires scaffolding to maintain patency. The Tack Endovascular System provides minimal-metal dissection repair that preserves future treatment options. Tack implants are designed to minimise the inflammation and neointimal hyperplasia that lead to in-stent restenosis. An independent angiographic core laboratory evaluated the restenosis patterns in clinically driven target lesion revascularisation (CD-TLR) during the 12 months following the index procedure in the Tack Optimized Balloon Angioplasty (TOBA) II study and compared these results to those published for nitinol stent implantation. Of the 213 patients in TOBA II, 31 (14.6%) required a CD-TLR. Of these, 28 had angiograms that were evaluated by the core laboratory, and 45.2%, 16.1%, and 29% were graded as Tosaka class I, II and III, respectively. There were no significant differences (p>0.05) in lesion length, degree of calcification or dissection class between the three groups. Tack restenotic lesion classification and analysis show a prevalence of both class I and shorter lesions relative to in-stent restenosis, which may be beneficial to long-term patient outcomes.

Purpose: To examine whether laser atherectomy combined with drug-coated balloons (laser + DCB) can improve the outcomes of femoropopliteal (FP) in-stent restenosis (ISR). Methods: A dual-center retrospective study was conducted of 112 consecutive patients (mean age 70.3±10.6 years; 86 men) with Tosaka class II (n=29; diffuse stenosis) or III (n=83; occlusion) FP-ISR lesions. Sixty-two patients (mean age 68.5±10 years; 51 men) underwent laser + DCB while the other 50 patients (mean age 72.5±10.8 years; 35 men) had laser atherectomy plus balloon angioplasty (laser + BA). Critical limb ischemia was the indication in 33% of the interventions. The average lesion length was 247 mm. A Cox regression hazard model was developed to examine the association between laser + DCB vs laser + BA; the results are presented as the hazard ratio (HR) and 95% confidence interval (CI). One-year target lesion revascularization (TLR) and reocclusion were estimated using the Kaplan-Meier method. Results: Overall procedure success was 98% and was similar between groups. Bailout stenting was less often required in the laser + DCB group (31.7% vs 58%, p=0.006). The combination of laser + DCB was associated with improved 12-month estimates for freedom from TLR (72.5% vs 50.5%, p=0.043) and freedom from reocclusion (86.7% vs 56.9%, p=0.003). Among patients with Tosaka III FP-ISR, combination therapy with laser + DCB was also associated with increased freedom from reocclusion (87.1% vs 57.1%, p=0. 028). On multivariable analysis, treatment with laser + DCB was associated with a significantly reduced risk of reocclusion (HR 0.08, 95% CI 0.17 to 0.38; p=0.002). Conclusion: When used for treatment of complex FP-ISR lesions, DCB angioplasty combined with laser atherectomy is associated with significantly reduced 1-year TLR and reocclusion rates.

Purpose: Carotid artery stenting (CAS) appears as a promising alternative treatment to carotid endarterectomy for radiation therapy (RT)-induced carotid stenosis. However, this is based on a poor level of evidence studies (small sample size, primarily single institution reports, few long-term data). The purpose of this study was to report the long-term outcomes of a multicentric series of CAS for RT-induced stenosis. Methods: All CAS for RT-induced stenosis performed in 11 French academic institutions from 2005 to 2017 were collected in this retrospective study. Patient demographics, clinical risk factors, elapsed time from RT, clinical presentation and imaging parameters of carotid stenosis were preoperatively gathered. Long-term outcomes were determined by clinical follow-up and duplex ultrasound. The primary endpoint was the occurrence of cerebrovascular events during follow-up. Secondary endpoints included perioperative morbidity and mortality rate, long-term mortality rate, primary patency, and target lesion revascularization. Results: One hundred and twenty-one CAS procedures were performed in 112 patients. The mean interval between irradiation and CAS was 15 ± 12 years. In 31.4% of cases, the lesion was symptomatic. Mean follow-up was 42.5 ± 32.6 months (range 1–141 months). The mortality rate at 5 years was 23%. The neurologic event-free survival and the in-stent restenosis rates at 5 years were 87.8% and 38.9%, respectively. Diabetes mellitus (p=0.02) and single postoperative antiplatelet therapy (p=0.001) were found to be significant predictors of in-stent restenosis. Freedom from target lesion revascularization was 91.9% at 5 years. Conclusion: This study showed that CAS is an effective option for RT-induced stenosis in patients not favorable to carotid endarterectomy. The CAS was associated with a low rate of neurological events and reinterventions at long-term follow-up.
