Dear Editor,
With great deal of interest, we read the article “Three-Dimensional in Vivo Anatomical Study of Female Iliac Vein Variations” by Zhang et. al. [Citation1]. The authors presented the following female iliac vein variations based on CT imaging: absence of common iliac vein mainly on the right side, abdominal communication between left common iliac vein and right internal iliac vein and division of internal iliac vein into two branches plus convergence with the ipsilateral external iliac vein.
In the literature several other variants are presented e.g. formation of left common iliac vein by the convergence of four veins [Citation2] or posterior extrapelvic tributaries to the internal iliac veins [Citation3].
Wenling Zhang et al. highlight in their study the importance of identification of such anatomic variations in order to minimize vascular injury risk [Citation1]. We would also like to discuss the possible risk of May-Thurner syndrome in such variations [Citation4]. May-Thurner syndrome is the compression of the left common iliac vein between the lower lumbar spine and the right common iliac artery which may be correlated with deep vein thrombosis and post thrombotic events. In such patients, anticoagulation, angioplasty or thrombectomy might be essential as preventative measures [Citation5].
Once again, we would like to thank the authors for their excellent manuscript.
