title: Surgical and endovascular interventions for nutcracker syndrome.
abstract: Nutcracker syndrome is a rare condition of left renal vein entrapment manifesting with hematuria, flank pain, and, occasionally, pelvic congestion in females or varicocele in males. Diagnosis requires a high index of suspicion upon careful history delineation. The gold standard for definite confirmation remains venography with renocaval pressure gradient. Treatment is mainly guided by the severity of symptoms. For the majority of centers, it appears that surgery remains the first-line therapy, however, endovascular alternatives are rapidly evolving into the field with favorable outcomes. This article reviews current concepts on nutcracker syndrome with particular focus on contemporary surgical and endovascular techniques and their outcomes.
