title: Portal vein thrombosis related to Cassia angustifolia.
abstract: BACKGROUND
  Cassia angustifolia (Senna), used as a laxative, is a plant from the Fabaceae family. It includes hydroxyanthracene glycosides, also known as Senna Sennoside. These glycosides stimulate the peristalsis of the colon and alter colonic absorption and secretion resulting in fluid accumulation and expulsion. In the literature, there are reports illustrating the hepatotoxic effects of Cassia angustifolia but there is no report of portal vein thrombosis caused by Cassia Angustifolia.
  
  
  METHODS
  A 42-year-old woman was admitted to the emergency department with a five-day history of worsening epigastric pain, anorexia, episodic vomiting, and intermittent fever. She reported that she had boiled dried senna leaves she had bought from herbalists and drank approximately 200 mL daily for two years. Color Doppler screening found an echogen thrombus obliterating portal vein bifurcation and the right branch. The lumen was obstructed at this level and there was no blood flow through it. Treatment with thrombolytics was unsuccessful.
  
  
  CONCLUSIONS
  Severe hepatotoxicity senna use is unusual. The cause of senna-related hepatotoxicity is unclear but could be explained by the exposure of the liver to unusual amounts of toxic metabolites of anthraquinone glycosides.
  
  
  CONCLUSIONS
  Chronic use of Cassia angustifolia may rarely be associated with portal vein thrombosis.
