Ethylene-vinyl alcohol polymer trans-arterial embolization in emergency peripheral active bleeding: initial...

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Emergency Medicine

Background:

• Active peripheral arterial bleeding presents a significant clinical challenge.
• Traditional treatments may carry substantial risks and limitations.

Purpose of the Study:

• To assess the efficacy and safety of superselective embolization using ethylene-vinyl alcohol copolymer (Onyx) for emergency arterial bleeding.
• To evaluate clinical outcomes in patients treated with Onyx embolization.

Main Methods:

• Retrospective analysis of 15 patients with active peripheral arterial bleeding treated between January 2014 and June 2014.
• Superselective embolization using Onyx as the primary treatment modality.
• Multidetector computed tomography and digital subtraction angiography for diagnosis and confirmation.

Main Results:

• 100% technical success and immediate bleeding control rates were achieved.
• No rebleeding occurred within 30 days post-embolization.
• No major complications or treatment-related deaths were observed during a mean follow-up of 5.1 months.

Conclusions:

• Superselective embolization with Onyx is a feasible and safe primary treatment for massive active peripheral emergency arterial bleeding.
• This technique offers excellent hemostasis with a low complication rate.
• Onyx embolization provides a reliable alternative for managing critical arterial hemorrhage.
