[Hybrid operations in treatment of patients with multi-level lesions of lower limb arteries]

The article is a review of literature dedicated to simultaneous open and endovascular (hybrid) operations in treatment of patients with chronic ischaemia of lower limbs. Despite good results of endovascular interventions, in many situations involvement of arteries below the inguinal fold and multilevel lesions are arguments in favour of performing an open operation. On the other hand, open multilevel interventions are accompanied by an increased risk of complications and mortality. Hybrid interventions appear to be a safe and efficient alternative combining advantages of two methods of treatment and making it possible to achieve an optimal outcome with a minimal surgical wound. Also discussed herein are the problems of terminology, indications for, techniques and results of treatment, providing a historical background, followed by analysing problem spots of using this technique and trends of development.

The effect of the stented iliac lesions TASC-II C, D on the femoropopliteal bypass patency: Propensity score-matched observational study

INTRODUCTION

Concurrent stenting of complex iliac lesions during infrainguinal bypasses can increase the complexity of a case and impact outcomes.

OBJECTIVE

Our aim was to evaluate the effect of inflow stenting of TASC-II C, D iliac lesions on femoropopliteal bypass patency.

METHODS

A retrospective observational cohort study of patients who underwent femoropopliteal bypass with TASC-II C, D iliac artery stenting (hybrid group) or without inflow lesions (non-hybrid group) was conducted. After propensity score matching, 120 patients were included in the non-hybrid group and 60 patients in the hybrid one. The median follow-up was 432 (193; 1313) days in the hybrid group and 472 (196; 1376) days in the non-hybrid group (p = 0.94).

RESULTS

No significant differences were found between the groups in 30-day morbidity and serious adverse events. At 3 years, primary and secondary bypass patency for the hybrid group and non-hybrid group were 62.2% versus 59.9% (p = 0.36) and 63.7% versus 64.3% (p = 0.077), respectively. The primary patency of the iliac stents in patients of the hybrid group was 95% at 3 years. The estimated hazard ratio for primary patency for hybrid versus non-hybrid was 0.77, with 90% CI: 0.50-1.21; the noninferiority upper bound being 1.31, which corresponds to a 10% additive noninferiority margin for probabilities. The 3 years of freedom from amputation in patients with chronic limb-threatening ischemia was 94.1% and 75.0% in the hybrid and non-hybrid groups, respectively (p = 0.09).

CONCLUSION

The outcomes of the femoropopliteal bypass in hybrid surgery supplemented with stenting of TASC-II C, D iliac lesions was similar to femoropopliteal bypass with intact inflow arteries.
