Résumé
Aortic dissection (AD) is a life-threatening vascular disease due to the tearing of aortic intimal layer, leading to the formation of pseudocavity. Once the acute progression of dissection happens, serious complications such as rupture and stroke may occur. The current imaging examinations for AD are invasive and may cause adverse effects related to contrast medium, which cannot be used for large-scale screening of AD. The latest studies have found that metabolic processes and metabolites of lipids,saccarides and proteins are involved in the pathogenesis and development of AD. In this article, we review the research progress in the caracteristics of AD related metabolism,summarize changes of specific metabolites in AD,and explore the clinical implication of studies on AD related metaboliome..
Résumé
Objective:To evaluate the efficacy and safety of drug-coated balloon (DCB) with paclitaxel in the treatment of femoropopliteal artery in-stent restenosis.Methods:From Dec 2016 to Jul 2020, clinical and follow-up data of femoropopliteal artery in-stent restenosis (ISR) treated with paclitaxel DCB were retrospectively analyzed.Results:Firty-two patients (56 lower limbs) with femoropopliteal artery ISR underwent DCB therapy. According to Rutherford classification, 1 case was R2 (1.7%), 9 cases were R3 (23.2%), 23 cases were R4 (41.1%), 15 cases were R5 (26.8%) and 4 cases were R6 (7.1%). According to Tosaka classification of ISR, 46 (81.2%)limbs were Tosaka Ⅱ, 10(17.9%)limbs were Tosaka Ⅲ Mean lesion length of ISR was (240±122)mm. Bail-out stent implantation was performed in 25% cases. The median follow-up time was 18 months. The all-cause mortality rate was 11.8%, the major amputation rate was 5.9%, the primary patency rate was 53.4%, the primary assisted patency rate was 67.1%, the secondary patency rate was 93.2%, and the F-TLR was 77.2%.Conclusion:DCB is a safe and effective endovascular therapy for femoropopliteal artery ISR.
