There is a lot of clinical interest in deploying stents in iliac veins for thrombotic and non thrombotic disorders.
Stent failure is a major clinical issues following stent deployment. An emerging body of clinical pearls have been learned in stenting iliac veins. However, the "nherent angles and configurations of the iliac veins have not been thoroughly studied".
Researchers at the Department of Vascular Surgery, Peking Union Medical College, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, Beijing, China have investigste this. They have mapped out the iliac veins in urology patients and the major angles of the iliac veins were measured.
- All measurements were made with patients in the supine position.
-
- The autohors demonstrated several relatively constant angles along the pathway of the iliac veins.
-
- The pathway of the left iliac veins was found to be more complex than that of the right side. This surmised that the "difference in the angles might be related to the patients' age and bone structures. They concluded that these angles should be considered in planning iliac vein stenting as well as in designing stents specifically for the iliac veins.
