Angiography and ultrasound-guided therapeutic embolization in iatrogenic vascular injury

Objective To evaluate the angiographic manifestations and clinical value of ultrasound-guided therapeutic embolization in iatrogenic vascular injury.Methods 22 cases with vascular injuries caused by surgical process or interventional punction were collected.Arteriogrphy was performed in 19 cases,11 cases underwent thera-peutic embolization,and 3 cases were treated by ultrasound-guided thrombin injection.Results In 19 cases,extravasation of contrast medium was found in 8 cases,pseudoaneurysm in 7 cases,arteriovenous fistula in 1 case,and artery dissecting and occlusion in 3 cases.After embolization,the bleedings were stopped in 7 patients,with no occurrence during following-up;one died for multiple organ failure;bleeding occurred in 2 cases;one was treated by arterial em-bolization again.3 patients who underwent ultrasound-guided thrombin injection cured.Conclusion Arteriogrphy and ultrasonography are determinant for the diagnosis and therapeutic choice,and effective and safe in the treatment of iatrogenic vascular injury.
