Abstract:
This was a single-center retrospective case series study. This study evaluated the efficacy and safety of percutaneous covered stent endovascular exclusion under digital subtraction angiography (DSA) for removing dialysis catheters misplaced in arteries. The clinical data from 7 patients treated in the First Affiliated Hospital of Zhejiang University School of Medicine from January 2012 to October 2023 were analyzed. All patients had dialysis catheters confirmed to be misplaced in arteries via chest CT, X-ray radiography or computed tomography angiography. Percutaneous covered stent endovascular exclusion under DSA was used to remove the catheters. The results showed that except for one elderly patient died during waiting for surgery, the remaining 6 patients achieved satisfactory outcomes with no postoperative bleeding. There was no related complication observed during a 6-month follow-up. Arterial misplacement of dialysis catheters is a serious complication requiring prompt removal. Percutaneous covered stent endovascular exclusion under DSA offers a minimally invasive, effective, and safe approach with a high technical success rate and a low complication rate, making it a viable surgical option for similar clinical cases.
