[Treatment of iliac vein thrombosis by use of filter placed in the inferior cava vein in a female patient after reoperation of meningioma of the smaller section of the sphenoid bone].

Deep phlebothrombosis is a one of the postoperative complications in neurosurgery in 90% localized in lower extremities. The brain contains the highest concentration of tissue thromboplastin compared with the other organs. That fact plays an important roll in pathophysiology of thrombo-embolic process in neurosurgery. The most frequent places of thrombogenesis are venous sinus of soleus muscle and gastrocnemius muscle, next: deep veins of crus, femoral veins and iliac veins. We describe the case of the efficient treatment of femoral vein and iliac vein thrombosis using filter placed under control of monitor in the inferior caval vein higher than the thrombus.
