PTFE mesh in renal allograft compartment syndrome.
2006
We report a case of anuria in a 42-year-old female kidney transplant patient that occurred secondary to extrinsic compression from a large kidney being placed extraperitoneally in a small iliac fossa. Prompt reexploration in the immediate postoperative period resulted in salvage of the graft with restoration of kidney function. The abdominal wall was reconstructed using prosthetic mesh, which decreased the compartment pressure within the iliac fossa sufficiently to allow the renal vein patency and the kidney perfusion. We think that this tension-free surgical technique should be applied in those cases in which the retroperitoneal space is less than the size of the kidney to avoid renal allo…
Sources of human plasma cyclic AMP. Examinations before and after beta 2 adrenergic stimulation.
1981
Plasma cyclic AMP was measured in different vessels in seventeen volunteers before and after stimulation with terbutaline. Differences between arterial blood and blood from the hepatic vein, right ventricle, inferior vena cava and a cubital vein could not be demonstrated. Only in the renal vein was the concentration of cyclic AMP decreased. Our results indicate that cyclic AMP is not generated from any specific isolated organ and that changes in cyclic AMP after subcutaneous injection of terbutaline reflect a general influence of this drug.
Bolus-enhanced renal spiral CT: technique, diagnostic value and drawbacks
1994
Abstract In addition to pre- and postcontrast renal CT scans, early bolus-enhanced spiral scans during demarcation of the corticomedullary junction were acquired in 85 patients. The diagnostic value and drawbacks of the three imaging series in the evaluation of renal disease were assessed. Renal calcifications and calculus disease detected at precontrast scans (18%) were obscured after contrast administration and excretion in most cases. In the detection of renal lesions bolus-enhanced spiral CT and delayed postcontrast scans had an identical diagnostic yield (94%). Bolus-enhanced spiral CT was superior in the assessment of lesion vascularity and vascular anatomy as well as opacification of…
Treatment of Idiopathic Varicoceles by Transfemoral Testicular Vein Occlusion
1981
Percutaneous transfemoral occlusion of the testicular vein is a new alternative in the treatment of idiopathic varicocele. Embolization with the Gianturco coil was done on 27 patients. The occlusion was performed immediately after diagnostic phlebography. The results of followup for 1 year are available for 18 patients. In 1 patient the coil had to be removed because of persistent pain, although cause and effect could not be proved. Two patients had a recurrence. The urographic findings were normal 1 year after embolization. No dislocation of the foreign body was observed. Two patients reported that their wives were pregnant.
Transposition of the left renal vein for treatment of the nutcracker phenomenon: long-term follow-up
2002
Abstract Objectives To assess the therapeutic value of left renal vein transposition for treatment of the nutcracker phenomenon in long-term follow-up. Methods Eight patients (4 women and 4 men) between 23 and 58 years old (mean 39.1) underwent transposition of the left renal vein for treatment of the nutcracker phenomenon associated with recurrent gross hematuria and flank pain. The postoperative follow-up was 41 to 136 months (mean 66.4). Results No perioperative complications were encountered. The postoperative complications comprised deep vein thrombosis (n = 1), retroperitoneal hematoma necessitating surgical revision (n = 1), and paralytic ileus that resolved with conservative managem…
The Nutcracker Syndrome: New Aspects of Pathophysiology, Diagnosis and Treatment
1991
Magnetic resonance imaging (MRI) was used to study vascular anatomy in 3 patients with the nutcracker syndrome and in 10 healthy volunteers. From these studies an abnormal branching of the superior mesenteric artery from the aorta was identified as being the cause of the nutcracker syndrome. Consequently, surgical transposition of the left renal vein to achieve an unobstructed renal venous backflow was performed successfully in 2 patients, while 1 underwent nephrectomy. In 1 patient adjuvant ureteral instrumentation became necessary to aid occlusion of persisting shunts between peripelvic venous varicosities and the urinary tract. Awareness of the pathophysiology of the nutcracker syndrome …
Retroaortic left renal vein joining the left common iliac vein
2000
Retroaortic left renal vein joining the left common iliac vein is a rare congenital anomaly in the development of the inferior vena cava. To our knowledge, only one case has been reported in the literature; however, its imaging features have never been described. A 27-year-old male presented with a 1-year history of recurrent right flank pain, dysuria, hematuria, and fever (39 degrees C). Computed tomography and MR venography showed a retroaortic left renal vein joining the left common iliac vein. We present the CT and MR venography findings and discuss their feasibility in showing this congenital anomaly.
Retroaortic left renal vein: a report of six cases
1992
Six cases of retroaortic left renal vein have been studied, two in corpses and four by means of Computed Tomography. Any previous pathology has been rejected. The total number of dissected specimens was 116, whereas the patients with non-pathological retroperitoneum studied by CT numbered 170. In our six cases, the left renal vein formed a single trunk of considerable size, retroaortic position and directed obliquely towards the inferior vena cava.
Congenital renal arteriovenous malformation (aneurysmal type) in childhood.
1985
We report on a 9-year-old boy with a congenital renal arteriovenous fistula of the aneurysmal type, a form previously not observed in childhood. The clinical picture was unusual with severe arterial hypertension, excessive polyuria and decreased levels of serum sodium and chloride as main signs. Clinical and biochemical findings normalised after nephrectomy of the kidney involved.
Nutcracker syndrome due to left renal vein compression by an aberrant right renal artery
2007
Classic nutcracker syndrome is caused by left renal vein compression between the superior mesenteric artery and aorta, leading to retrograde venous hypertension associated with such urinary abnormalities as hematuria or proteinuria. We describe a case of symptomatic nutcracker syndrome treated by means of stent placement in which hypertension in the left renal vein was caused by stenosis of this vein compressed by an aberrant right renal artery at a point closer to the inferior vena cava.
