左髂总静脉狭窄与急性下肢深静脉血栓形成

目的探讨左髂总静脉狭窄程度与深静脉血栓形成的关系。方法对１９９１年９月～１９９７年３月的６３例急性髂股静脉血栓（ＤＶＴ）病例的一般资料、血栓形成诱因、手术方法及结果进行了回顾性分析。结果左髂总静脉直径较正常狭窄≥４７．１％时血栓形成的病例数骤然增加。结论左髂总静脉直径狭窄接近一半时，随时可能发生血栓形成，但因侧支代偿而不发病。一旦血栓形成的诱因出现，将可引起血栓发生。因而，遇有血栓形成的诱因时，应行多普勒超声检查。

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.
