Revascularização venosa via transposição de veia gonadal esquerda em síndrome de nutcracker posterior: relato de caso

The Nutcracker Syndrome is manifest in the presence of a symptomatic entrapment of the left renal vein between the abdominal aorta and the superior mesenteric artery. In a more ephemeral variation of this disorder, called the Posterior Nutcracker Syndrome, the renal vein is not compressed anterior to the aorta, but posteriorly, between the artery and the spine. Although there are multiple treatment options, current techniques aim to relieve the symptoms and reduce venous pressure on the left renal vein. This report describes a case of Posterior Nutcracker Syndrome in which the management approach chosen was open surgery, transposing the gonadal vein distally, to the inferior cava vein.
