Percutaneous transhepatic biliary drainage catheter fracture: A case report

摘要

Percutaneous transhepatic biliary drainage (PTBD) is safe treatment for biliary decompression given certain indications. However, this is temporary until definitive drainage is established. We report on a 76-year-old lady with recurrent pyogenic cholangitis and PTBD catheter fracture. She had hepatitis B virus-related Child-Pugh class A liver cirrhosis, hypothyroidism, hyperlipidaemia, and previous atrial fibrillation with a background of mild mitral, tricuspid and aortic valvular regurgitation. She had history of laparoscopic cholecystectomy in the past. She was deemed to be a high operative risk and declined hepatic resection. She had undergone multiple endoscopic and percutaneous biliary interventions to control sepsis and stone burden. A bilateral PTBD catheter was left in situ with plans for 3-monthly change. However, she defaulted follow-up and presented 11 months later with complaints of pain over the drain site and inability to flush the right catheter. Abdominal X-ray and computed tomography scans detected right catheter fracture at two places, making three fragments. She underwent percutaneous removal of the proximal fragment by an interventional radiology team. A temporary 4 Fr catheter was inserted to maintain biliary access. Endoscopic removal of the intra-biliary fragments was done the next day. Complete removal was confirmed on fluoroscopy. Finally, the 4 Fr catheter was replaced by a new 12 Fr catheter. The patient was discharged well.
