title: [Diameter and length measurement of infrarenal inferior vena cava in Shandong Peninsula adult and its significance].
abstract: OBJECTIVE
  To measure the diameter and length of infrarenal inferior vena cava (IVC) in Shandong Peninsula adult through digital subtraction angiography (DSA) for better vena cava filter (VCF) choice and placement.
  
  
  METHODS
  From April 2008 to June 2010, 83 discontinuous patients (49 males and 34 females, mean age 56.4 years) with deep venous thrombosis (DVT) of lower extremity were placed VCF through DSA according to ACCP-8. During operation, diameter and length of infrarenal IVC were measured. At the same time, the renal vein location and the type of the IVC were identified to help the VCF choice.
  
  
  RESULTS
  All the VCFs were placed successfully, no complications occurred. The diameter of infrarenal IVC was 10 to 26 mm with a mean of (19 ± 5) mm. The average length from beginning of IVC to the lower renal vein was (10.6 ± 2.8) cm. The renal vein was located between the first and second lumbar vertebra, the IVC beginning was located between the fourth and fifth lumbar vertebra.
  
  
  CONCLUSIONS
  Diameter and length measurement of infrarenal IVC is helpful to the VCF selection and the domestic VCF research. Vena cava angiography is very important to the accurate placement of VCF.
