The purpose of this study was to evaluate the clinical characteristics of 44 pediatric patients who were diagnosed as having nutcracker syndrome (NCS). We also investigated the left renal vein Doppler ultrasonography (DUS) results, to determine whether or not there was an association between clinical symptoms and DUS findings among these patients. The clinical data from 44 pediatric patients who were diagnosed as having NCS from January 2008 to December 2015 were retrospectively reviewed. We grouped the patients according to the presenting symptoms as symptomatic (loin pain; macroscopic hematuria or both) and non-symptomatic (microscopic hematuria and proteinuria were detected incidentally) and evaluated the left renal vein DUS indices in these two groups separately. Asymptomatic NCS was found in 27 (61.4%) patients; 21 (47.7%) of whom were admitted for the evaluation of proteinuria. The most frequent presenting symptoms were left flank pain (20.5%) and macroscopic hematuria (13.6%); and 2 (4.5%) patients presented with a combination of left flank pain and macroscopic hematuria. The mean ratio of the diameter of the hilar portion of the left renal vein (LRV) to that of the aortomesenteric portion was 4.36 ± 1.55. The mean ratio of the peak velocity (PV) between the two sites of the LRV was 7.32 ± 2.68 (3.1–15.6). The differences in the ratio of the diameters were statistically significant between the two groups and significantly higher in children with asymptomatic NCS (p = 0.025). The PV ratios of the LRV (p = 0.035) were significantly higher in asymptomatic children with NCS than in the symptomatic group. Our study identifies that increased compression ratio of the LRV entrapment is most observed in orthostatic proteinuria and microscopic hematuria.

Nutcracker syndrome includes all the symptoms associated with the narrowing of the left renal vein (LRV). That narrowing occurs between the aorta and the Superior Mesenteric Artery (anterior) or vertebra (posterior). The symptoms are various and not specific but the patient sometimes presents hematuria with or without left flank pain. We report a case on a 42 years old woman, who was suffering from left flank pain for a long time aggravated during and after each pregnancy. The diagnosis of nutcracker syndrome was initially omitted. Abdominal pelvic Angio CT and venography were performed. We placed a percutaneous stent in the narrowed portion of the renal vein. The result was successful.

Retroperitoneal lipoma presenting with a nutcracker-like phenomenon is extremely rare. I experienced a case of a 65-year-old man presenting with left flank pain and macrohematuria intermittently for 3 years. Computed tomography revealed a lipoma at the left pedicle of the kidney, 30 mm in diameter, causing a curving of the left renal artery and dilatation of the left renal vein. This patient was treated successfully by retroperitoneoscopic resection of the lipoma. There have been no symptoms for 10 years after the operation.

The anterior nutcracker syndrome is defined by the compression of the left renal vein between the aorta and superior mesenteric artery, usually related to the occurrence of hematuria. We report the case of an uncommon complication of the nutcracker syndrome. A 75-year-old woman was referred to our institution for left flank pain without hematuria. Multiphasic computer tomography urography showed a condition of left renal vein entrapment between the aorta and superior mesenteric artery with the development of left gonadal vein varicosities at the level of the renal hilum; a pyeloureteral junction compression with dilation of the pyelocalyceal system coexisted. To our knowledge, this is the first report of the association between nutcracker syndrome and pyeloureteral junction obstruction.

This paper ilustrates the imaging aspect of a rare pathology- aorto-mesenteric compression syndrome (Wilkie's disease). In this disease acute angulation of the superior mesenteric artery will lead to compression of the duodenum and of the left renal vein. Duodenal compression may lead to delayed gastric emptying and to nutcraker syndrome when left flank pain and hematuria may be present

Nutcracker syndrome is a rare entity in which compression of the left renal vein (LRV), usually by the overlying superior mesenteric artery (SMA), results in renal venous congestion and reflux in the left ovarian vein (LOV). Patients may present with hematuria, left flank pain, dyspareunia, and vaginal or abdominal wall varicose veins. We report a patient with nutcracker syndrome who presented atypically with left flank pain that was exacerbated in the postprandial state. We hypothesize that the physiologic dilation of the SMA after oral intake caused increased LRV compression at that site and augmented lateral LRV distention. The patient had no evidence of SMA syndrome or chronic mesenteric insufficiency. Her symptoms resolved after we performed an LOV to inferior vena cava transposition.

Nutcracker syndrome (NCS) seems to be an under-diagnosed condition defined as external compression of the left renal vein and consequent blood outflow impairment. The majority of cases involve the left renal vein entrapment between abdominal aorta and the superior mesenteric artery. The exact epidemiology is unknown due to lack of consensus on diagnostic criteria and often asymptomatic courses. NCS may occur at any age with peak presentation in the second and third decade of life. There is a slight prevalence in females. The most frequent presentations include micro and macroscopic hematuria, orthostatic proteinuria, orthostatic hypotension, flank pain. Patients may develop pelvic congestion syndrome comprising dyspareunia, dysmenorrhea, abdominal pain, pelvic, gluteal, vulvar varicose veins and varicocele in men. Clinical suspicion of NCS based on signs and symptoms, requires imaging confirmation utilising modalities such as doppler ultrasonography, computed tomography and magnetic resonance angiography, intravascular ultrasound and phlebography. Treatment options of NCS range from conservative surveillance to nephrectomy, thus appropriate approach should be based on clinical manifestation and severity of symptoms. Patients presenting with mild to moderate haematuria, and acceptable symptoms should be treated conservatively. In cases of severe symptoms or when conservative management fails, invasive treatment should be considered. Recommended open surgical procedures include left renal vein distal transposition and renal autotransplantation. Endovascular stenting approach seems to be an encouraging solution.  Further long term follow-up is required to create objective treatment guidelines.

Isolated renal vein thrombosis is a rare entity. We present a patient whose complaint of flank pain led to the diagnosis of a renal vein thrombosis. In this case, abdominal computed tomography angiography was helpful in diagnosing the nutcracker syndrome complicated by the renal vein thrombosis. Anticoagulation was started and three weeks later, CTA showed complete disappearance of the renal vein thrombosis. To treat the Nutcracker syndrome, we proposed left renal vein transposition that the patient consented to.

Nutcracker syndrome refers to the symptomatic extrinsic compression of the left renal vein presenting most commonly as flank pain and haematuria. While surgery remains the first-line treatment, stenting is gaining more acceptance and there are now several published case series. This article highlights the outcomes of left renal vein stenting in the setting of nutcracker syndrome.

AbstractNutcracker syndrome is defined as a compression of left renal vein leading to symptomatic hematuria and flank pain. There are very few reports about its association with May–Thurner syndrome that is related to compression of left iliac vein causing severe leg edema. We are reporting a rare case of a patient having both conditions successfully treated with sequential percutaneous interventions. This case and treatment options are discussed in detail.
