“…DUS criteria for the nutcracker syndrome include the five times increase in flow velocity in the LRV before and in the site of compression is related to have sensitivity of 80% and specificity near to 95% for nutcracker syndrome. Also the post-stenotic peak systolic velocity more than 100cm/s is a good parameter to consider a high-gradecompression [7][8][9].…”

Left Renal Vein compression, entitled as Nutcracker Syndrome, usually is described as cause of Pelvic Congestion once the difficult of drainage of the left kidney deviate vein flow to Gonadal vein developing Pelvic varices in women, and Varicocele in men. Recurrence of Varicocele is described to be between 1 to 35%, dependent on the surgical technique used to repair it. Among the cause of recurrent varicocele, include surgical technique failure, low Body Mass Index, venous plexus variation (persistence of branched spermatic veins), and venous compression. In this study, the authors present 2 cases of recurrent varicocele in young men caused by pelvic congestion due to the Left Renal Vein (LRV) and Left Common Iliac Vein (LCIV) compression, treated by endovascular techniques with good results. In the Literature there are few papers relating the association of both syndromes. Authors discuss of the association of recurrent varicocele and pelvic congestion, and also suggest a routine investigation of it in this recurrence.

“…The normal aortomesenteric angle and distance are 25–60° and 10–28 mm, respectively [ 6 ]. However, in SMAS this angle is narrowed to <25° and the distance is shortened to < 8 mm [ 7 , 10 ]. Several factors are associated with SMAS, mainly marked weight loss as a consequence of other diseases (cancer, bariatric surgery, chronic infections, severe burns) but may also be congenital such as shorten Treitz’s ligament or abnormal origin of the SMA, or associated with surgical interventions that distorts the anatomy as scoliosis correction or esophagectomy [ 3 , 4 , 6 ].…”

Wilkie’s syndrome, or superior mesenteric artery syndrome (SMAS), is a rare clinical entity caused by compression of the third portion of the duodenum between the abdominal aorta and superior mesenteric artery, leading to duodenal obstruction and severe malnutrition. The authors report a case of a female patient with years of chronic intestinal obstruction with abdominal pain, vomits and weight loss. Contrast intestinal series showed dilation of stomach and duodenum. Abdominal computed tomography study revealed findings compatible with SMAS. After initial nutritional support, she was successfully treated by laparoscopic duodenojejunostomy. Surgical treatment of SMAS may be necessary in most cases with chronic symptoms or conservative treatment failure. A minimally invasive approach can be considered a safe surgical option with favourable outcomes. Clinical details, diagnostic studies and treatment are discussed.

“…The five times increase in flow velocity offers sensitivity of 80% and specificity close to 95% for nutcracker syndrome. 11 Doppler spectral analysis can also be used to measure the post-stenotic peak velocity, which normally exceeds 100 cm/s. 12 Computed tomography and magnetic resonance imaging (MRI) are additional methods, but in the past they were little used for diagnosis of nutcracker syndrome.…”

Diagnóstico e tratamento da síndrome de quebra-nozes (nutcracker ): revisão dos últimos 10 anos

et al. 2018

View full text Add to dashboard Cite

Resumo A síndrome de quebra-nozes é caracterizada por um grupo de manifestações clínicas que ocorrem por conta da compressão da veia renal esquerda. Seus principais sintomas são macro e micro-hematúria, proteinúria e dor no flanco. O diagnóstico é geralmente realizado após a exclusão de outras causas mais comuns, por conta da ausência de critérios clínicos para diagnóstico. Sua confirmação é feita por exames de imagem, com uso da ultrassonografia Doppler e tomografia computadorizada. O tratamento pode variar com as características do paciente e com a gravidade dos sintomas, e inclui o tratamento conservador, a cirurgia aberta e a cirurgia endovascular. Atualmente, a cirurgia aberta continua sendo a linha de frente, mas abordagens menos invasivas vêm ganhando cada vez mais espaço.
