Haemostasis with the FISH Vascular Closure Device after 6 French Transfemoral Accesses in Interventional Radiology: Clinical Results

Hemorrhagic complications after endovascular interventions and the effectiveness of vascular closure devices

Aim. To identify the factors associated with hemorrhagic complications after endovascular interventions, as well as to assess the effectiveness of vascular closure devices.

Material and methods. The study included 423 patients after endo - vascular intervention with femoral arterial access: 118  — manual compression, 305  — hemostasis using vascular closure devices (VCDs). The development of following complications was recorded: retroperitoneal hematoma, false aneurysm, arteriovenous fistula, bleeding, thigh soft-tissue hematoma. Time to hemostasis, immobilization period, and length of stay were assessed.

Results. The complication rate was lower in VCD group compared to manual hemostasis (2,95 vs 11%, p=0,021). In VCD group, hemostasis characteristics significantly differed from the manual compression group: time to hemostasis — 3,1 vs 22,3 min (p=0,001), immobilization duration  — 4,1 vs 20 hours (p=0,001), length of stay  — 4 vs 8 days (p=0,001), respectively. The risk of complications increased with following factors: anticoagulant therapy, female sex, age >65 years, diabetes, body mass index >30 kg/m2 , vascular access calcification, introducer diameter >6 Fr, prior puncture. There were following independent predictors of complications: glycoprotein IIb/IIIa inhibitor therapy, superficial or deep femoral artery puncture.

Conclusion. VCDs significantly reduces the hemorrhagic complication rate and improves hemostasis parameters as compared to manual compression.
