extravascular stent management for migration of left renal vein endovascular stent in Nutcracker Syndrome
BMC Urology, 2015Co-Authors: Lu Tian, Shan-wen Chen, Gaoyue Zhang, Hongkun Zhang, Wei JinAbstract:Nutcracker Syndrome is an entity resulting from left renal vein compression by the aorta and the superior mesenteric artery, which leads to symptoms of hematuria or left flank pain. The alternative option of endovascular or extravascular stenting is very appealing because of the minimal invasive procedures. Stents in the renal vein can cause fibromuscular hyperplasia, proximal migration or embolization. A 30-year-old female was diagnosed with Nutcracker Syndrome for severe left flank pain. After failed conservative approach, she underwent endovascular stenting and subsequently developed recurrent symptom for stent migration one month postoperatively. She underwent successful extravascular stenting with complete symptom resolution. The extravascular stenting is an alternative option after migration of left renal vein endovascular stenting. The computed tomographic imaging was closely correlated to therapeutic interventions and stent migration.

Nutcracker Syndrome how well do we know it
Urology, 2014Co-Authors: Shan-wen Chen, Lu Tian, Wei Jin, Hongkun ZhangAbstract:Nutcracker Syndrome (NCS), which is caused by compression of the left renal vein between the abdominal aorta and the superior mesenteric artery, leads to a series of clinical symptoms including hematuria, proteinuria, flank pain, and varicocele. The diagnosis of NCS is difficult due to variations in normal anatomy. Treatment, which ranges from observation to nephrectomy, remains controversial. We conducted a review based on the related literature and our experience with hundreds of cases. We summarize the characteristics of NCS, the different measurements used in diagnosis, and the current treatment options. We present our diagnostic criteria and recommend endovascular stenting as the primary option for NCS.

endovascular management of Nutcracker Syndrome after migration of a laparoscopically placed extravascular stent
American Journal of Kidney Diseases, 2012Co-Authors: Shan-wen Chen, Hongkun Zhang, Lu TianAbstract:Nutcracker Syndrome results from compression of the left renal vein between the superior mesenteric artery and the aorta, leading to symptoms of hematuria and left flank pain. Management options include endovascular or laparoscopic extravascular stent placement, which is very appealing given the minimally invasive nature of these procedures. We report a case of migration of a laparoscopically placed extravascular stent for Nutcracker Syndrome that was treated successfully by endovascular stent placement.

Left renal vein transposition in treatment of the left renal vein Nutcracker Syndrome
Zhejiang da xue xue bao. Yi xue ban = Journal of Zhejiang University. Medical sciences, 2004Co-Authors: Zhou-jun Shen, Shan-wen Chen, Xiao-dong Jin, Shi-fang ShiAbstract:Objective: To improve the operative procedure of the left renal vein Nutcracker Syndrome. Methods: Two patients underwent transposition of the left renal vein in the treatment of the left renal vein Nutcracker Syndrome. Results: Renal ischemia, due to clamping of the renal artery, lasted 14 minutes and 13 minutes, respectively. The gross hematuria disappeared 1 day and 4 days respectively after surgery, and microhematuria ceased spontaneously 5 days and 7 days respectively after surgery. Transposition of the left renal vein effectively relieved the symptoms related to the left renal vein Nutcracker Syndrome. The patients had no recurrence of symptoms following up during 3 months. Conclusion: Transposition of the left renal vein is a safe and effective surgical approach in the treatment of the left renal vein Nutcracker Syndrome.

laparoscopic transposition of the left renal vein into the inferior vena cava for Nutcracker Syndrome
Journal of Vascular Surgery, 2010Co-Authors: Olivier Hartung, Pierre Barthelemy, Amine Azghari, Mourad Boufi, Yves S AlimiAbstract:Reimplantation of the left renal vein into the infrarenal inferior vena cava is the standard surgical procedure for Nutcracker Syndrome. A 40-year-old woman with a solitary left kidney suffered from left lumbar pain and hematuria. Imaging techniques found a large kidney with Nutcracker Syndrome. A totally laparoscopic transposition of the left renal vein was performed. Twelve months later, the patient is improved and has no more hematuria. Duplex scan showed no residual stenosis. Laparoscopic transposition of the left renal vein into the inferior vena cava is feasible with short length of stay and good short-term result.

laparoscopy assisted left ovarian vein transposition to treat one case of posterior Nutcracker Syndrome
Annals of Vascular Surgery, 2009Co-Authors: Olivier Hartung, Pierre Barthelemy, Stephane Berdah, Yves S AlimiAbstract:We report one case of posterior Nutcracker Syndrome treated by left ovarian vein (LOV) transposition. A 36-year-old woman was suffering from Nutcracker Syndrome associated with pelvic congestion Syndrome. Color duplex scan, computed tomographic scan, and angiography demonstrated a stenosis of a retroaortic left renal vein with proximal dilatation and incompetence of the LOV. The renocaval pullback gradient was 10 mm Hg. The LOV was harvested laparoscopically and transposed into the inferior vena cava. Completion angiography showed a patent reconstruction with no significant gradient. At day 4, an asymptomatic thrombosis was treated by thromboaspiration. Forty months later, the patient remained asymptomatic with a patent transposition. Posterior Nutcracker Syndrome is a rare condition. When associated with pelvic congestion Syndrome due to LOV reflux, it can be treated by LOV transposition.

robotic assisted laparoscopic transposition of the left renal vein for treatment of the Nutcracker Syndrome
Urology, 2015Co-Authors: Ping Wang, Taile Jing, Jie Qin, Dan Xia, Shuo WangAbstract:Nutcracker Syndrome is a rare condition of left renal vein entrapment manifesting with hematuria and flank pain. We report a case of Nutcracker Syndrome, where a robotic-assisted laparoscopic transposition of the left renal vein was performed. To our knowledge, this is the first case of robotic-assisted laparoscopic surgery of a Nutcracker Syndrome.
