ABSTRACT

Objective:To evaluate percutaneous mechanical thrombectomy (PMT) using Aspirex device for treating acute iliofemoral deep vein thrombosis (IFDVT).Methods:The clinical and follow-up data of 68 patients with IFDVT at our institution from Jan 2019 to Jun 2021 was retrospectively analyzed.Results:Twenty-six patients who had received PMT combined with auxiliary catheter directed thrombolysis (CDT) were included into group A, and 42 patients received CDT alone were into group B.The final thrombus clearance rates were more than 50%, and the clinical efficacy of thrombolysis was achieved. Group A associated a significant reduction in lysis duration and UK dosage and hospital days and degree of detumescence after 24 h compared with group B,and all aforementioned differences were statistically significant. Hospitalization costs in group A were more than group B. At one year follow-up, there were no significant differences between the two groups in the cumulative prevalence post-thrombotic syndrome (PTS) and the Villalta score and primary patency (92.0% vs. 90.0% , χ2=0.059, P=0.807). Conclusions:The application of PMT using the Aspirex device for acute IFDVT was safe and effective, which could accelerate the clearance of thrombus, and reduce UK dosage, lysis duration, hospital days. However, it increased the hospitalization costs.

ABSTRACT

Adjustment of epigenetics is closely related with transfer modulation of tumor-related genes. DNA methylation is one of the significant functions of modulation of genetic epigenetics. Abnormal DNA methylation is intensively involved in generation and development of tumor while DNA methylation is cata- lyzed and maintained by DNA methyltransferase(DNMT). So profound study on funetions of DNMT is of great significance to realize generation of abnormal methylation and functions of abnormal methylation in tumor generation and development.
