Retrospective Analysis of 120 Cases of Iatrogenic and Traumatic Peripheral Arterial Pseudoaneurysms.

OBJECTIVE

The pseudoaneurysm formation is the most common complication of arterial catheterization. This study aimed to report our clinical experience with the treatment of iatrogenic and post-traumatic pseudoaneurysms of the peripheral arteries.

MATERIALS AND METHODS

One hundred twenty patients, who were treated with the diagnosis of arterial pseudoaneurysm of the lower or upper extremity artery between January 2010 and October 2017, took part in this study. Patients with pseudoaneurysms originated from the anastomotic line of the previous vascular operations were excluded from the study. The diagnosis of pseudoaneurysms was made using ultrasonography and confirmed by magnetic resonance imaging (MRI) or computed tomography (CT) scan when deemed necessary.

RESULTS

The most frequent symptom was a pulsatile mass. The mean diameter of pseudoaneurysms was 4.7±1.8 cm (2.3-8 cm). Among 120, 108 patients underwent surgery, and 10 patients required a blood transfusion during the operation. Wound infection was reported in 20 (15.5%) patients as an early postoperative complication. Arterial thrombosis developed in 6 (4.5%) patients, venous thrombosis in 2 (1.7%) patients, and lymphorrhea in 15 (12.5%) patients. A male patient died on the postoperative 25th day, while two patients died on postoperative 10th and 12th days (2.5%).

CONCLUSION

Although lesser invasive treatment modalities have been described with some advantages or disadvantages, open surgical repair is the standard method of treatment for iatrogenic and traumatic peripheral arterial pseudoaneurysms.
