The rupture of hepatic hydatid disease into the right hepatic vein and bile ducts: a case report.

Echinococcus granulosus and Echinococcus multilocularis cause liver hydatid disease. One of its most common complications is rupture into the bile ducts; however, penetration of a cyst into a vessel is a very rare complication. We detected a defect (2 x 1 cm) on the wall of the right hepatic vein, in addition to three distinctive ruptures into the bile ducts, in our case. For systemic hypotension due to a bleeding during operation and to repair the vessel wall defect, an urgent right thoracotomy followed by a radial phrenotomy was needed. We were able to reach the operation site easily and repaired the vessel wall with polypropylene suture. Because of the occurrence of these two complications together and the difficulties of the operation, we decided to report this case.
