# A multicenter prospective study evaluating use of EmboCube™ Embolization Gelatin alone or in combination with other embolic agents to control bleeding

## TL;DR

This study shows that EmboCube embolization gelatin is safe and effective for stopping bleeding, either alone or with other agents.

## Contribution

The study provides real-world evidence of EmboCube's safety and effectiveness in controlling bleeding across multiple hospitals.

## Key findings

- EmboCube achieved 100% technical success and 99% clinical success in stopping bleeding.
- No unanticipated serious adverse events were linked to EmboCube use.
- Only 4.4% of patients experienced adverse events within 28 days of treatment.

## Abstract

Embolization is a vital endovascular procedure that can be used to quickly achieve hemostasis in patients experiencing uncontrolled bleeding. This study was conducted to describe real-world outcomes following embolization with a pre-cut absorbable gelatin sponge to control bleeding.

This prospective study was conducted across five hospitals in Australia and France. Inclusion criteria included adults ≥ 18 years who required embolization with EmboCube™ Embolization Gelatin for bleeding. Primary performance and safety endpoints were the proportion of patients that achieved clinical success (i.e., cessation of bleeding post-embolization, the absence of rebleeding at the treated site requiring reintervention within 24 h), and the absence of unanticipated serious adverse device effects within 24 h of the initial embolization, respectively. Secondary endpoints included technical success and serious device- and/or procedure-related adverse events 28 days post-initial embolization.

A total of 101 patients (54 males) were enrolled and treated. Sixty-six patients were treated with EmboCube only, 35 patients were treated with an additional embolic to control bleeding. Technical and clinical success rates were 100% and 99%, respectively. No patient experienced an unanticipated serious event related to the embolic. The mean time to hemostasis was 3.4 (± 3.96) minutes. Of the 90 patients that completed 28 days of follow-up, 4 (4.4%) experienced an adverse event (access site hematoma, n = 2; ischemic colitis, n = 1, peritonitis, n = 1).

EmboCube is safe and effective for control of acute and sub-acute arterial bleeding, alone or in combination with other embolic agents, when rapid hemostasis is required.
