Percutaneous thrombolysis via cholecystostomy catheter to dissolve biliary clots causing obstructive jaundice

Abstract

Haemobilia, or bleeding within the biliary tree, is rare. It can cause biliary obstruction secondary to blood clots. A comorbid 87-year-old was admitted to hospital with acute cholecystitis, choledocholithiasis, and an Escherichia coli bacteremia. He had a partial pancreatectomy and gastrojejunostomy 35 years prior for severe pancreatitis. He was treated with antibiotics and a percutaneous cholecystostomy. He developed atrial fibrillation and was subsequently commenced on warfarin. He re-presented 5 days after discharge with abdominal pain and fevers. Liver function tests revealed cholestasis and a supratherapeutic international normalised ratio. Imaging showed cholecystitis, biliary obstruction, and extensive biliary blood clots. He improved with antibiotics, vitamin K, and alteplase flushes through the percutaneous cholecystostomy. Repeat cholangiogram demonstrated dissolution of the biliary clots. Due to altered anatomy and comorbidities, alteplase flushes were utilized to relieve this patient’s biliary obstruction. Thrombolytics may assist in treating biliary clots when first-line options are not possible or favourable.
