title: Preaortic left primitive iliac vein: two case studies.
abstract: Although congenital abnormalities of the inferior vena cava (IVC) are rare, they can lead to serious hemorrhagic complications, especially during aortoiliac surgery. The most frequent complications include the double IVC, left-sided IVC, and the left retroaortic renal vein isolated or associated with a preaortic renal vein forming a periaortic venous collar. Preaortic primitive iliac vein represents an exceptional anatomic entity and only a few cases have been reported in previously published data (Ruemenapf et al., J Vasc Surg 1998;27:767-771; Schiavetta et al., J Vasc Surg 1998;28:719-722; Shindo et al., Ann Vasc Surg 2000;14:393-396; Balbridge and Canos, Arch Surg 1987;122:1184-1188; Honkasalo et al., Acta Chir Scand 1983;149:717-719; Brener et al., Arch Surg 1974;108:159-165; Vohra and Leiberman, Eur J Vasc Surg 1991;5:209-211; McClure and Huntington, Am Anat Memoirs 1929;15:1-55). In this study, we report two cases of preaortic left primitive iliac vein. The first patient was a male who was operated on for an aortobiiliac aneurysm. The second was of a female patient who was operated on for an interaortocaval lymphadenopathy that resulted from ganglion curettage performed for ovarian cancer.
