[Acute arterial occlusion associated disseminated hydatidosis].

Hydatidosis or echinococcosis are terms used to denote the zoonotic infestation caused by adult and larval stages (metacestode) of the cestode from the genus Echinococcus (family tenidae). The term hydatidosis should be applied to the infestation caused by the metacestode while echinococcosis for the larval and adult stages. In Peru there is a high prevalence of this infection, liver and lung being the most affected organs. There are factors from the host and from the infectious agent that contribute to this infection, with the immune component of the host as an important infection and dissemination point. A case of acute arterial occlusion associated with disseminated hydatidosis in a 54 years old patient, born and from Huancavelica, with sudden onset of an acute arterial obstruction is reported. The patient did not improve after surgery and died within 48 hours of presentation.
