Safety and effectiveness of repeat arterial closure using the StarClose vascular closure device in patients with hepatic malignancy

Efficacy and Safety of Axiostat® Hemostatic Dressing in Aiding Manual Compression Closure of the Femoral Arterial Access Site in Patients Undergoing Endovascular Treatments: A Preliminary Clinical Experience in Two Centers

BACKGROUND

Hemostasis of the femoral arterial access site by manual compression or a vascular closure device is critical to the safe completion of any endovascular procedure. Previous investigations evaluated the hemostatic efficacy at the radial access site of some chitosan-based hemostatic pads. This study aims to assess the efficacy and safety of a new chitosan-based hemostatic dressing, namely Axiostat^®, in aiding manual compression closure of the femoral arterial access site in patients undergoing endovascular treatments. Furthermore, the outcomes were compared with evidence on manual compression alone and vascular closure devices.

METHODS

This investigation is a two-center retrospective analysis of 120 consecutive patients who had undergone, from July 2022 to February 2023, manual compression closure of the femoral arterial access site aided by the Axiostat^® hemostatic dressing. Endovascular procedures performed with introducer sheaths ranging from 4 Fr to 8 Fr were evaluated.

RESULTS

Primary technical success was achieved in 110 (91.7%) patients, with adequate hemostasis obtained in all cases of prolonged manual compression requirements. The mean time-to-hemostasis and time-to-ambulation were 8.9 (±3.9) and 462 (±199) minutes, respectively. Clinical success was achieved in 113 (94.2%) patients, with bleeding-related complications noted in 7 (5.8%) patients.

CONCLUSIONS

Manual compression aided by the Axiostat^® hemostatic dressing is effective and safe in achieving hemostasis of the femoral arterial access site in patients undergoing endovascular treatment with a 4-8 Fr introducer sheath.

Safety and Effectiveness of Suture-mediated Arterial Closure Device in Hepatocellular Carcinoma Patients Who Underwent Drug-Eluting Beads Transarterial Chemoembolization

BACKGROUND

The number of transarterial percutaneous procedures has risen over the years, consequently reducing puncture site related complications has become a necessity. To this end, the use of arterial closure devices has been growing progressively and their benefits have become a focus of research. The purpose of this study is to assess the safety and effectiveness of a suture-mediated closure device, Perclose ProGlide^® (Abbott Vascular, Redwood City, CA), in patients with liver disease and hepatocellular carcinoma who underwent transarterial liver chemoembolization with drug-eluting beads.

MATERIALS AND METHODS

A cohort of 253 hepatocellular carcinoma patients who underwent 449 procedures of transarterial liver chemoembolization with drug-eluting beads using the Perclose Proglide device was prospectively studied. The main endpoints evaluated were the technical success of the device, defined as complete hemostasis achieved within 3 min after the closure, and the incidence of puncture-site complications. The secondary endpoints evaluated were the correlation between epidemiological factors, coagulation profile and degree of liver disease, and the occurrence of complications.

RESULTS

Technical success was achieved in 96% of the cases. Among patients who underwent repeated procedures using the same vascular access, this rate was 95.3%. Puncture-site complications were observed in 7 procedures (1.56%); 4 (0.89%) were due to hemorrhage, 2 (0.44%) hematomas and 2 (0.44%) pseudoaneurysms; 2 (0.44%) due to limb ischemia; and 1 (0.22%) due to arterial dissection. Among them, 3 cases required intervention. The statistical analysis of demographic characteristics, Child-Pugh classification, and coagulation status did not show a significant correlation with the occurrence of complications. Of the 449 procedures, only 4 (0.89%) needed hospitalization due to puncture-site complications.

CONCLUSIONS

The use of Perclose Proglide is safe and effective in patients with liver disease and hepatocellular carcinoma who underwent transarterial liver chemoembolization with drug-eluting beads.
