To explore the endovascular technique in the treatment of iatrogenic vascular injury (IVI).

Medical records of 11 patients who suffered from IVI and underwent endovascular treatment at our institute from December 2018 to June 2022 were reviewed. There were 4 cases of venous IVI, 5 cases of arterial IVI and 2 case of intravascular foreign body. The treatment of IVI included intravascular compression, embolism of the vascular rupture, percutaneous intravascular stent implantation (PISI) and intravascular suture with vascular closure devices (VCDs). The intravascular foreign body was captured by using a snarer assisted with a catheter. The methods of endovascular treatment were analyzed, and the operation success and complications related to the operation were concerned.

Technical success was achieved in 11 patients (100%). One patient with venous IVI underwent PISI during the process, and was detected with in-stent thrombosis at post-operative 3 days. One patient with arterial IVI was treated with intravascular compression combined with injection of procoagulant drugs for pseudoaneurysm, and the femoral artery pseudoaneurysm recurred 4 days later, then underwent surgery. One patient died 4 days after endovascular compression combined with embolization, but there was no correlation between the endovascular treatment of IVI. All the other cases had no obvious complications related to the treatment, and no death was encountered. The clinical success rate of operation was 81.82%, and the incidence of complications was 9.09%. There were no serious complications related to the operation.

As a minimally invasive method to treat IVI with small trauma and rapid post-operative recovery, endovascular technique is worthy of clinical promotion. Meanwhile, pre-operative evaluation and post-operative observation should also be concerned.
