Management of traumatic peripheral artery pseudoaneurysm: A 10-year experience at a single center

This study aimed to report our 10-year experience with the management of iatrogenic (penetrating trauma) and traumatic (blunt or penetrating trauma) peripheral artery pseudoaneurysms, based on data from a tertiary referral center.

From January 2012 to December 2021, the medical records of consecutive patients with iatrogenic and traumatic peripheral artery pseudoaneurysms were retrospectively reviewed. Patient demographics, clinical features, imaging data, treatment details, and follow-up results were analyzed.

Sixty-one consecutive patients were included in this study; 48 (79%) were men and 13 (21%) women, with a mean age of 49.4 ​± ​13.4 years (range 24-73 years). There were 42 patients (69%) who underwent open surgery, 18 (29%) undergoing endovascular embolization or stent implantation, and one (2%) undergoing ultrasound-guided thrombin injection. All patients successfully underwent open or interventional treatment. The median follow-up was 46.8 months (2.5-117.9 months), and the overall reintervention rate was 10%. Of these, one (5%) patient in the interventional treatment group and five (12%) patients in the open surgery group underwent reintervention. The overall complication rate was 8%, with complications occurring only in the open surgery group. No deaths occurred in the peri-operative period. No late complications, such as thrombosis or pseudoaneurysm recurrence, were observed.

Peripheral artery pseudoaneurysms arising from iatrogenic or traumatic causes can be effectively treated by both open surgery and interventional procedures in selected patients with acceptable mid- and long-term outcomes.
