肝胆道常规操作中的血管并发症及其管理：介入放射科医师的视角和病例系列

Hepatic and biliary interventions, though routinely performed, can lead to significant vascular complications such as bleeding or pseudoaneurysm formation. These injuries usually result from vessel trauma during needle puncture, catheter manipulation, or stent placement and can cause life-threatening hemorrhage if unrecognized. Interventional radiology offers minimally invasive, effective alternatives to surgical management through timely diagnosis and targeted embolization. We present four cases of vascular injuries following common hepatobiliary procedures, each successfully managed using endovascular techniques, underscoring the critical role of interventional radiology in their prompt detection and treatment.
