Musculoskeletal synovial abnormalities and treatments

Between January 1991 and December 1993, duplex ultrasound characterization of venous disease in leg swelling was studied in 214 patients (261 limbs; 167 unilateral and 47 bilateral). All patients were examined with a duplex scanner, the superficial and deep venous systems were evaluated for the presence of thrombus and valvular incompetence. Of the 261 limbs, 29 (11.1%) had deep venous thrombosis, 14 (5.4%) had superficial venous thrombosis, 66 (25.3%) had deep venous incompetence (31/66 limbs also had superficial venous incompetence), 65 (24.9%) had incompetence in the superficial veins only. and five (1.9%) had deep venous obstruction resulting from a popliteal cyst or a popliteal vein ligation. Eighty‐two limbs (31.4%) had no evidence of venous obstruction or incompetence at the areas evaluated. This study showed that venous obstruction and valvular incompetence had occurred in two‐thirds of swollen legs examined. Some of the venous obstructions resulted from surgically treatable diseases such as a popliteal cyst, and some of the venous disorders involved the superficial venous system only. Complete venous evaluation with duplex imaging can be very helpful in the determination of the underlying cause of the swelling.
