Síndrome de quebra-nozes: o que há de novo?
Abstract
The nutcracker syndrome occurs due to extrinsic compression of the left renal vein between the aorta and the superior mesenteric artery. Despite the clinical relevance of this syndrome, there are few Brazilian publications on the subject, and underdiagnosis of the condition is frequent. The objective was to perform a bibliographical review on the nutcracker syndrome. This is a literature review from articles published in the last 47 years in the following databases: Scholar Google, SciELO, Pubmed Central®, ScienceDirect. Nutcracker syndrome has several manifestations, with the most common being pain in the left flank and hematuria. The diagnosis is difficult and can be often late. There are several treatment options, with open surgical procedure being the most accomplished, and of these, left renal vein transposition has been the most used and effective surgical approach in the treatment of the syndrome. A less invasive alternative to open surgical treatment that is gaining space is the endovascular approach, although some complications have been reported. Nutcracker syndrome is clinically difficult to diagnose, is na important differential diagnosis of hematuria, requires high clinical suspicion and is potentially treatable. Thus, this article will expand the scientific literature on the subject in order to contribute to the reduction of underdiagnosis of the syndrome.\n.
