Abstract:
Objective To study the application effects of different inferior vena cava filters(IVCF)placed in the renal vein for the treatment of deep vein thrombosis(DVT).Methods A total of 102 patients with lower limb DVT who underwent renal vein IVCF at the Second People's Hospital of Baoshan from January 2021 to June 2022 were selected.According to the type of IVCF,patients were divided into a retrievable group(n=51)and a permanent group(n=51).The two groups were compared in terms of filter placement conditions,perioperative limb circumference differences,D-dimer,fibrinogen,venous recanalization scores,venous recanalization rates,as well as complications and recurrence-free survival status 12 months post-operation.Results The surgical success rate was 100%.The differences in limb circumference above the knee(15 cm)and below the knee(10 cm)at 1 day,3 days,and 7 days post-operation were significantly reduced compared to pre-operative measurements and showed a downward trend(P<0.05).D-dimer and fibrinogen levels at 1 day,3 days,and 7 days post-operation were also significantly reduced compared to pre-operative levels,with a downward tren(P<0.05).The venous recanalization scores at 7 days post-operation were significantly lower than pre-operative scores in both groups(P<0.05).The incidence of postoperative complications in the retrievable group was lower than that in the permanent group(P<0.05).Conclusion The placement of a retrievable IVCF on the renal vein for endovascular treatment of DVT has significant therapeutic effects,can adjust the circumference difference of the lower limb,improve coagulation function,and reduce the incidence of complications and recurrence.
