Left renal veins of 77 patients were examined by computed tomography (CT) to evaluate its usefulness in determining the left renal vein compression which is causing renal bleeding. From CT image, left renal vein compression was observed in 6 (86%) of the 7 cases which had been classified as idiopathic renal bleeding, in 9 (21%) of the 42 cases which had urinary tract diseases causing hematuria, and in 3 (11%) of the 28 cases which did not have hematuria. In 15 of the 18 cases of left renal vein compression, left renal vein was compressed between the superior mesenteric artery and the abdominal aorta, showing so-called nutcracker phenomenon. In the remaining 3 cases, however, the superior mesenteric artery provided sharp delineation from the abdominal aorta. The superior mesenteric artery and the abdominal aorta made the mean angle of 35.5 degree in patients with normal left renal vein, the mean angle of 45.4 degrees in those with left renal vein compression without nutcracker phenomenon, and the mean angle of 11.9 degrees in those with nutcracker phenomenon. CT was superior to ultrasonography, in revealing left renal vein compression. 相似文献

INTRODUCTIONPosterior Nutcracker syndrome (NCS) is a rare anomaly in which the left renal vein passes behind the aorta which compresses it against the vertebral column, restricting the venous drainage of the left kidney.PRESENTATION OF CASEA 46 year-old lady presented with intermittent painless hematuria for 6 years. Urinalysis showed microscopic hematuria. An abdominal CT scan showed left renal vein duplication with the retroaortic branch trapped between the vertebral column and the aorta at the level of the aortic bifurcation, suggestive of posterior NCS. There were multiple small cortical cysts, sand-like stones in the left kidney and duplication of both right and left renal arteries.DISCUSSIONPosterior NCS in a patient with a duplicated left renal vein may not show all the clinical features of a typical NCS as the elevated pressure due to compression is dissipated through the pre-aortic branch of the duplicated renal vein. CT Angiography can be helpful in such a patient with multiple abnormalities. Management can range from simple surveillance to nephrectomy depending on the symptoms and renocaval pressure gradient.CONCLUSIONAlthough posterior NCS is a rare anomaly of the left renal vein, it should be considered in the differential diagnosis of haematuria. 相似文献

A case of a pre-aortic left renal vein compression by the aorta is reported. The clinical presentation was characterized by the left flank pain varying with body position. Renal venography was crucial for the diagnosis of this lesion. The left renal vein was successfully decompressed by ovarian vein-vena cava shunt surgery. The patient's left flank pain subsided after the surgery. This is the first reported case of a left renal vein compression syndrome by the aorta following the nephrotic syndrome. 相似文献

Large bronchial cyst causing compression of the left atrium. 总被引:2,自引:0,他引:2
Tohru Mawatari Toshiro Itoh Yoshikazu Hachiro Hideyuki Harada Takeshi Kobayashi Tatsuya Saitoh Hisayoshi Ohsawa Atsushi Watanabe Tomio Abe 《Annals of thoracic and cardiovascular surgery》2003,9(4):261-263
We describe here a case with a large bronchogenic cyst treated by surgical resection, who presented with evidence of left atrial overload on electrocardiogram (ECG). The 50-year-old male patient presented with the chief complaint of heaviness in the chest on exertion. An ECG revealed evidence of left atrial overload, and echocardiography and imaging revealed a mass having a maximum diameter of 9 cm on the cranial aspect of the left atrium, caudal to the tracheal bifurcation. The patient was treated by surgical resection of the cystic mass via right anterolateral thoracotomy. His postoperative course was satisfactory and the patient was relieved of his main symptom. 相似文献

Spontaneous aorto-left renal vein fistula: the "abdominal pain, hematuria, silent left kidney" syndrome 总被引:1,自引:0,他引:1
Spontaneous aorto-left renal vein fistula (ALRVF) is a rare occurrence; with this case, only 16 have been reported to date. Common features in patients with ALRVF include abdominal pain (81%), hematuria (100%), impaired renal function (85%), and nonvisualization of the left kidney (100%). Less common but also present in the majority of cases are a left sided bruit (73%), pulsatile abdominal mass (63%), and proteinuria (50%). Also important, 94% have a retroaortic left renal vein, unlike the six cases of traumatic ALRVF that have been reported. This magnifies the diagnostic value of contrast abdominal computed tomographic scanning, which demonstrates not only the anomalous location of the left renal vein but also the abdominal aortic aneurysm and poor enhancement of the left kidney. These findings rule out the possibility of the "nutcracker syndrome" (left renal vein compression between aorta and superior mesenteric artery). Although confirming the presence of a fistula by early caval opacification, aortography does not always distinguish ALRVF from the more common aortocaval fistula. This can be accomplished by Duplex scanning with deep probes and even preferably color coding of velocity signals. With such precise preoperative localization, surgical repair is relatively easy and safe. 相似文献

Ligation and division of the left renal vein is a reasonable safe procedure in selected patients when exposure of the perirenal aorta is crucial. This manipulation is possible because of extensive venous collateralization from the left kidney in man. Measurement of the venous stump pressure before ligation is recommended to assess the degree of collateralization, and the upper limit within which the vein may be divided safely is probably in the neighborhood of 60 cm of water. Reanastomosis of the vein is not necessary for preservation of renal function, although transient left renal dysfunction may occur. Examination of the urine and careful monitoring of renal function should be routine in the postoperative period. Intravenous urography and left spermatic venography later in the postoperative course can indicate the ultimate degree of function of the left kidney and the pathways of venous collateralization. Preservation of normal function and venous architecture at the renal hilum should be the rule. 相似文献

Noninvasive radiological diagnosis of renal vein thrombosis in renal transplantation. 总被引:1,自引:0,他引:1
Thrombosis of the allograft renal vein is a rare complication of renal transplantation. Of 557 consecutive renal transplants performed between January 1, 1985 and November 30, 1989, 3 cases occurred for an over-all incidence of 0.4%. In 2 cases the diagnosis was made preoperatively with renal scintigraphy and duplex Doppler sonography. No graft was salvaged, despite timely diagnosis in 2 patients. We conclude that the diagnosis of renal vein thrombosis in the renal allograft recipient should be suspected clinically and by the radiographic findings of absent perfusion on renal scintigraphy, and the detection of an arterial signal, albeit abnormal, on duplex Doppler sonography. When diagnosed, nephrectomy appears to be the only treatment. 相似文献

Transposition of the left renal vein in nutcracker syndrome. 总被引:1,自引:0,他引:1
J Y Kim J H Joh H Y Choi Y S Do S W Shin D I Kim 《European journal of vascular and endovascular surgery》2006,31(1):80-82
Mesoaortic compression of left renal vein produces left renal vein hypertension resulting in left flank pain, hematuria and pelvic-ureteral varices. This is called the nutcracker syndrome. The nutcracker syndrome has been treated in various ways. We recently experienced two cases of patients with nutcracker syndrome. We treated the patients with transposition of their left renal vein. 相似文献
