The paper reports on surgical cases of treatment of dirofilariasis Dirofilaria repens in the Tomsk Region. Dirofilariasis - transmissible tissue helminthiases, characterized by damage to the skin, subcutaneous tissue, mucous membranes (Dirofilaria repens) or internal organs: heart, lungs, bronchi and large blood vessels (Dirofilaria immitis). Until recently, the disease was considered exclusively zoospecific, so doctors did not study it. To date, little is known about it and it is not immediately possible to make a diagnosis. Due to the fact that in recent years cases of infection of people in the territory of the Russian Federation, including in the Tomsk Region, have become more and more frequent, the description of the clinical picture, methods of diagnosis and surgical treatment of this disease is relevant.
