CANADIAN PECULIARITIES
R.D. Moore et al. Cystic
Hydatid Lung Disease in Northwest Canada. 1994.
Can J Surg;37(1):20-22
- Echinococcus granulosis var. canadensis
- cystic hydatic lung disease in NW Canada:
- involves lung more often than liver
- relatively benign natural history
- associated with wild natural hosts
- wolf (and dogs) definitive host
- ungulates (moose, caribou, reindeer) intermediate hosts
- "sylvatic" strain (Canada) versus "pastoral" (World)
- pastoral strains more likely to involve liver, there are generally more
complications, and the natural hosts are domestic animals
- role of surgery less clearly defined in "sylvatic" disease?
- surgery recommended for symptomatic, infected, or enlarging pulmonary
cysts
- asymptomatic patients can be observed
- cyst rupture intraoperatively appeared to be harmless as well as difficult
to avoid as the sylvatic form has extremely delicate cyst wall
