To evaluate the effectiveness of percutaneous arterial embolization in patients with penetrating peripheral arterial trauma.

Selective embolization with n-butyl cyanoacrylate is technically feasible and effective in treating lower extremity penetrating injuries.

Participants
12 patients presenting with lower extremity penetrating injuries participated in this retrospective review of trauma cases.

Methodology
12 patients (11 males, 1 female) with a history of lower limb trauma to the peripheral arteries were treated with percutaneous transcatheter embolization. All injuries were secondary to penetrating stab wounds. Bleeding vessels were embolized with n-butyl cyanoacrylate (nBCA) glue using coaxial microcatheter system.

Results
All patients had successful embolization of target vessels that were bleeding, which included the inferior gluteal, internal pudendal, branch of profunda femoris, superficial femoral, peroneal, and anterior tibial arteries.

Conclusions
Selective embolization with nBCA is technically feasible and effective in treating lower extremity penetrating injuries.

Reviewer’s Comments
nBCA is a potent permanent embolic agent and is usually reserved for treating arteriovenous malformations and refractory/failed embolizations with other agents. Reflux into nontarget vessels can lead to disastrous consequences with loss of limb or organ function.
