All the usual complications related to the surgical procedure and anesthesia apply. Postoperative risk factors related to hepatic hydatidosis include age, previous surgery for hepatic hydatidosis, localization in the hepatic center, the presence of biliary communications, and cystic evolutionary complications. [8] However, radical surgery techniques seem to be protective factors. [8]

Complications related to the parasite include the following:

  • Recurrence

  • Metastasis

  • Infection

  • Spillage and seeding (secondary echinococcosis): Allergic reaction or anaphylactic shock

Those related to the medical treatment include the following:

  • Hepatotoxicity

  • Anemia

  • Thrombocytopenia

  • Alopecia

  • Embryotoxicity

  • Teratogenicity

  • Spillage and seeding (secondary echinococcosis)

Complications related to puncture, aspiration, injection, and reaspiration (PAIR) intervention include the following:

  • Hemorrhage

  • Mechanical damage to other tissues

  • Infections

  • Allergic reaction or anaphylactic shock

  • Persistence of daughter cysts

  • Sudden intracystic decompression leading to biliary fistulas

Those related to scolicidal agents includes chemical sclerosing cholangitis.

A rare case of alveolar echinococcosis embolism that required emergency surgical intervention has been reported. [1]
