Case report: Emergency management of adjacent arterial injury during inferior vena cava angioplasty in a patient with Budd-Chiari syndrome.

Budd-Chiari syndrome (BCS) is a clinical syndrome caused by stenosis or occlusion of the hepatic veins and/or the inferior vena cava (IVC) near their orifices. Endovascular therapy is a common therapeutic approach. However, the puncture procedure during angioplasty may damage adjacent arteries, compromising patient safety and affecting clinical outcomes. This report describes a case of a patient with BCS who suffered an inadvertent injury to the origin of the right common carotid artery (CCA) during IVC angioplasty under angiographic guidance. Through multidisciplinary consultation and emergency intervention, three covered stents were precisely placed at the bleeding site, achieving successful hemostasis. This case report aims to provide a guidance for the early clinical recognition and management of such intraprocedural complications.
