[Stenosis of the common left iliac vein and acute deep vein thrombosis of the lower extremity].

OBJECTIVE
To study the relation ship between (DVT) acute deep vein thrombosis (DVT) of the lower extremity (DVT) and common left iliac vein compression by the common right iliac artery.


METHOD
We reviewed 63 cases of DVT from September 1991 to March 1997.


RESULTS
43 cases operated on the left leg showed when the stenosis reached nearly or beyond half of the lumen of iliac vein, the number of DVT increased greatly.


CONCLUSION
DVT will occur if the stricture of the left iliac vein reaches nearly or beyond half of the lumen. But there is no DVT because of collaterals. If the stricture of iliac vein exists, especially reaches nearly or beyond half of the iliac vein, preventive measures will be taken.
