Methods: 15 formaldehyde-preserved cadavers were studied with special attention to the variety and surrounding structure of ascending lumbar vein (ALV) and iliolumbar veins(ILV) , and their relationship with lumbar plexus.

Objective To investigate anatomic structural features of the lumbosacarl veins and provide anatomic bases for clinical lumbo- sacarl anterior approach Methods We dissected the iliolumbar veins and ascending lumbar veins from 20 formaldehyde-preserved cadavers(17male,3 female).

Study on imaging examinations for iliac vein compression syndrome;

Diagnostic value of CDFI for congenital iliac vein compression syndrome causing left iliac femoral venous thrombosis;

The imaging quality and imaging characteristic of iliac vein disease were analyzed.

Anatomic features of the confluence of the common iliac veins and its clinical significance;

An anatomical measurement was made in 101 adult cadavers tor the intervention of the cardiac tube through the external iliac vein.

All the cases were performed catheter of popliteal vein thrombolysis guided by B-ultrasound combined with intraluminal dilatating and stenting in the iliofemoral vein.
