Presented in this article is a clinical case report regarding treatment of a patient with deep vein thrombosis complicated by venous gangrene having developed 10 days after the onset of the disease. Conservative therapy (infusion of colloids and crystalloids, anticoagulants, agents improving microcirculation, venotonics, nonsteroidal anti-inflammatory drugs, elevated position of the limb) made it possible to stabilize the patient's condition, but not improving haemodynamics of the affected limb. A decision was made to use endovascular techniques.
