The modified interventional method of antegrade common femoral artery access closure using the Angio-Seal device: modified Angio-Seal haemostasis technique: Modified Angio-Seal haemostasis technique.

Aims: Antegrade femoral puncture is frequently performed in endovascular therapy, with haemostasis achieved through manual compression. The aim of this paper is to report the novel method of achieving haemostasis using the Angio-Seal device for antegrade punctures of the femoral artery. Methods and results: Between September 2017 and March 2018, a total of 50 consecutive patients who underwent endovascular therapies (EVT) through the common femoral artery with an antegrade puncture using a 6 Fr introducer sheath were retrospectively analysed. After EVT, all patients received a 6 Fr Angio-Seal STS Plus Vascular Closure Device. All procedures were performed using the following new technique. First, we inserted the Angio-Seal guidewire from the inserted EVT sheath into the artery. Second, we removed the EVT sheath and inserted the Angio-Seal sheath and then removed the dilator and Angio-Seal guidewire. Under angiography using an 18 G needle sheath, we pulled back the Angio-Seal sheath as near to the insertion site of the vessel as possible. Finally, a collagen sponge and plug were inserted as per the standard technique. In all patients, the Angio-Seal was successfully deployed, and haemostasis was achieved within several minutes. No major complications occurred. Conclusions: We demonstrated the feasibility and efficacy of achieving haemostasis using the Angio-Seal device in an antegrade femoral puncture using the novel method.
