Abstract

Aim: Retroaortic left renal vein (RLRV) is a usually asymptomatic anatomical variation whose detection frequency has increased relatively in parallel with the recently increased use of radiological imaging. In this study, we aimed to investigate if there is increased vein pressure in asymptomatic patients with RLRV. Materials and Methods: A total of 138 patients diagnosed with RLRV by contrast-enhanced computed tomography (the RLRV group) and 100 participants (the control group) with similar age and sex characteristics were included. Left renal vein diameter, RLRV diameter at the narrowest segment, and left gonadal vein diameter were measured and compared. Results: When the RLRV and control groups were compared, left renal vein diameter at the preaortic segment was found to be significantly greater in the patients with RLRV. Left gonadal vein diameter also was observed to have increased in these patients. Discussion and Conclusion: RLRV, though usually asymptomatic, can cause increased pressure in the left renal vein and gonadal veins by compressing the left renal vein posteriorly to the aorta. This pressure increase is important in the etiology of pelvic congestion in women and varicocele in men. It can also lead to clinical symptoms such as flank pain and hematuria.

Özet

Amaç: Retroaortik sol renal ven (RSRV), saptanma sıklığı son yıllarda artan radyolojik görüntülemeye paralel olarak görece artmış bulunan, genellikle asemptomatik bir anatomik varyasyondur. Çalışmamızda RSRV’li asemptomatik hastalarda ven basıncı artışı olup olmadığını incelemeyi amaçladık.Gereç ve Yöntemler: Kontrastlı bilgisayarlı tomografide RSRV saptanan 138 hasta (RSRV grubu) ve bu hastalarla yaş ve cinsiyet bakımından benzer 100 kişi (kontrol grubu) çalışmaya dahiledildi. Sol renal ven çapı, en dar olduğu segmentte RSRV çapı ve sol gonadal ven çapı ölçülüpkarşılaştırıldı.Bulgular: RSRV ve kontrol grupları karşılaştırıldığında preaortik segmentte sol renal ven çapıRSRV’li hastalarda anlamlı olarak daha geniş bulundu. Bu hastalarda sol gonadal ven çapınında artmış olduğu görüldü.Tartışma ve Sonuç: RSRV, sıklıkla asemptomatik olmakla birlikte, sol renal venin aorta arkasında sıkışmasıyla sol renal ven ve gonadal venlerde basınç artışına neden olabilir. Bu basınç artışıkadınlarda pelvik konjesyon, erkeklerde ise varikosel etiyolojisinde önemlidir. Aynı zamanda hematüri ve yan ağrısı gibi klinik semptomlara da yol açabilir.
