Clinical Summary

56-year-old male with swelling and pain in left lower extremity



Imaging Procedures and Findings

Left iliac vein is dilated and filled with hypodense thrombosis.



Venous thrombosis is obstruction of veins by clotted blood. Deep venous thrombosis (DVT) of the lower extremities is the usual source of pulmonary embolism. The pathogenesis of DVT consists of one or a combination of the following: stasis of venous flow, endothelial injury and hypercoagulability. There is a greater incidence in patients with heart disease, after surgery, especially orthopedic procedures, and in some malignancies. Clinical features of DVT lack specificity and sensitivity. About half of the patients with DVT are asymptomatic. Compression and Doppler ultrasonography are the most frequently used imaging studies for DVT. Ultrasonography is reliable for the diagnosis of deep venous thrombosis of the lower extremities in symptomatic patients. The major criterion for this diagnosis is loss of venous compressibility. Diagnostic accuracy is better for proximal lower extremities than for the infrapopliteal lower extremities and the upper extremities. The diagnosis can also be established with contrast phlebography and MR venography. MR venography is the optimal procedure for demonstrating thrombosis of central veins in the chest, abdomen and pelvis.


Final Diagnosis

DVT of left iliac vein
