Nutcracker syndrome

Sayf Al-Katib, Monisha Shetty, Syed Mohammad A Jafri, Syed Zafar H Jafri
A wide range of clinically important anatomic variants and pathologic conditions may affect the renal vasculature, and radiologists have a pivotal role in the diagnosis and management of these processes. Because many of these entities may not be suspected clinically, renal artery and vein assessment is an essential application of all imaging modalities. An understanding of the normal vascular anatomy is essential for recognizing clinically important anatomic variants. An understanding of the protocols used to optimize imaging modalities also is necessary...

BACKGROUND: Nutcracker syndrome is a rare entity, and in the majority of cases is the result of extrinsic compression of the left renal vein between the superior mesenteric artery and the aorta, associated with functional stenosis. OBJECTIVE: To present the case of a 19-year-old female with no significant medical history with confirmed diagnosed of nutcracker syndrome treated successfully by endovascular means. CLINICAL CASE: She was referred to the Vascular Surgery Department with a 6-month history of macroscopic haematuria, after other aetiologies were ruled out...

Parkinsonian-pyramidal syndrome (PPS) is an early onset form of Parkinson's disease (PD) that shows degeneration of the extrapyramidal region of the brain to result in a severe form of PD. The toxic protein build-up has been implicated in the onset of PPS. Protein removal is mediated by an intracellular proteasome complex: an E3 ubiquitin ligase, the targeting component, is essential for function. FBXO7 encodes the F-box component of the SCF E3 ubiquitin ligase linked to familial forms of PPS. The Drosophila melanogaster homologue nutcracker (ntc) and a binding partner, PI31, have been shown to be active in proteasome function...

Nutcracker syndrome (NCS) is symptomatic unilateral renal venous hypertension due to compression of the left renal vein between the superior mesenteric artery and aorta (anterior NCS) or between the aorta and spine (posterior NCS). The left ovarian or spermatic vein empties into the left renal vein and is an additional site of venostasis in about half the cases of NCS. The presenting symptom of NCS in about half the cases is atypical left flank pain suggesting a disorder of the lower ribs or thoracolumbar spinal junction, particularly as the pain worsens with standing and increased lumbar lordosis...

OBJECTIVES: We sought to evaluate renal parenchymal elasticity with Virtual Touch quantification of acoustic radiation force impulse imaging in nutcracker syndrome and to compare shear-wave velocity (SWV) values with grayscale Doppler sonography and laboratory findings. METHODS: Thirty-eight healthy volunteers and forty-three nutcracker syndrome patients were enrolled in this prospective study. SWV values for both kidneys in nutcracker syndrome patients and healthy volunteers were evaluated...

Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutcracker" syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome...

Nutcracker syndrome refers to the complex of clinical symptoms caused by the compression of the left renal vein (LRV) between the abdominal aorta and the superior mesenteric artery, leading to stenosis of the aortomesenteric portion of the LRV and dilatation of the distal portion. Hematuria, proteinuria, flank pain, varicocele and pelvic congestion may occur, occurring more frequently in young adults. Conservative management, might be the option whenever it is possible. When surgical treatment is required, classically open surgery have been performed, with major surgeries as LRV transposition or bypass techniques...

Knowledge of the anatomy of the pelvic, gonadal and renal veins is important to understand pelvic congestion syndrome (PCS) and left renal vein compression syndrome (LRCS), which is also known as the nutcracker syndrome. LRCS is related to PCS and to the presence of vulvar, vaginal and pudendal varicose veins. The diagnosis of the two syndromes is difficult, and usually achieved with CT- or phlebography. The gold standard is the intravenous pressure measurement using conventional phlebography. The definition of PCS is described as pelvic pain, aggravated in the standing position and lasting for more than 6 months...

BACKGROUND: Nutcracker syndrome, or mesoaortic compression of the left renal vein (LRV), with associated symptoms related to venous hypertension in the left kidney, is a rare entity that may result in severe symptoms requiring operative intervention. We report on 3 patients who presented with nutcracker syndrome, including one patient with a circumaortic LRV resulting in posterior nutcracker syndrome, who underwent successful endovascular treatment with renal vein stenting. A review of existing literature on endovascular management of nutcracker syndrome follows...

In this report we describe a patient with anterior renal nutcracker syndrome caused by extrinsic compression of the left-sided inferior vena cava between the aorta and the superior mesenteric artery, as it crossed the midline, with resultant left renal vein hypertension. The patient was successfully treated by transposition of the right ovarian vein, which created a bypass of the compressed inferior vena cava and resulted in complete resolution of symptoms.

PURPOSE: To retrospectively evaluate the ability of computed tomographic (CT) findings to discriminate nutcracker syndrome (NCS) from asymptomatic nutcracker phenomenon (NCP) and to investigate the diagnostic value of CT findings in diagnosis of NCS. METHODS: From January 2014 to April 2015, 216 patients who underwent initial urographic CT were included. Initially, 216 patients were categorized as "nutcracker" or "normal," based on the following CT criteria: (1) the presence of beak sign and (2) hilar-aortomesenteric left renal vein diameter ratio >4...

We report the case of a 30-year-old male patient undergoing a robotic-assisted laparoscopic left donor nephrectomy, where compression of the left renal vein between the superior mesenteric artery and aorta was noted on magnetic resonance angiography before the operation. The patient was diagnosed with nutcracker phenomenon and was noted to be asymptomatic at that time. This is the first reported case to date of a patient with nutcracker phenomenon who underwent a robotic-assisted laparoscopic donor nephrectomy...

The nutcracker syndrome refers to compression of left renal vein between the superior mesenteric artery and aorta. Renal abscess consists of purulent and necrotic material localised to the renal parenchyma. These two entities are extremely rare and their coincidence has not previously been described in literature. Here, we report a case of a 10-year-old girl who developed left renal abscess probably due to nutcracker syndrome.

The left renal vein (LRV) has many developmental variations; the two most common are the circumaortic and the retrocaval. Anterior nutcracker syndrome is the compression of the LRV between the aorta and superior mesenteric artery, whereas posterior nutcracker syndrome occurs between the vertebral column and the aorta. An adolescent male (aged 16 years) was referred to the emergency department for flank pain. CT findings showed the combination of anterior and posterior nutcracker syndrome in the left circumaortic renal vein, which has not previously been described in an adolescent...

Duplicated inferior vena cava is a rare anomaly, and thrombosis in one or both segments is even less frequent. We present a case of deep venous thrombosis of the left lower limb involving the popliteal, femoral, and iliac veins as well as the left segment of the duplicated vena cava and nutcracker syndrome. After catheter-directed thrombolysis complemented by mechanical thrombolysis, the compromised veins had complete revascularization; the nutcracker syndrome was treated with stent placement, followed by the use of anticoagulants...

OBJECTIVE: In this study, we sought to investigate the incidence of stent migration after endovascular stenting (EVS) in patients with nutcracker syndrome (NCS) and to discuss the related factors. METHODS: We retrospectively evaluated the data of all patients with NCS who were treated by EVS at our single center between January 2004 and October 2014. Data collection included details on clinical findings, radiologic evaluation, laboratory values, EVS procedure, stent size, and morbidity of stent migration...
